Diary of... a y9 SCIENCE class - March 22nd 2007

Hello,
Today wasn't one of most fun lessons but... all lessons can't be fun and this way enjoy more the better ones so...
Well, we continued with the topic about reactivity and Andy tried a demo but... it didn't work. He was trying to evaporate water and transport it through a tube to a test tube with magnesium in it, so that it reacted, and then transport the hydrogen given off to an upside down test tube full with water so that we could after do the hydrogen test. Well, we would have like to see it but... we are not gonna die, no? Something went wrong so nothing hapenned.
That's all folks.
See you.

Planning ahead - Year 7 - books due in on the Tuesday after you return

Year 7, as I mentioned today in class, your books will be collected in on the Tuesday after we return from the Easter break.

As I have said for year 8 below, MAKE SURE YOUR BOOK COMES IN by the end of the day at the latest. No book no mark, and the grades go towards next terms grade.

Planning ahead - Year 8 - books due in Next Tuesday

Year 8, as I mentioned in class today, I will be collecting your books in for marking next Tuesday, so make sure that your book is with me by the end of Tuesday at the very latest and all the work is complete.

The marks from that marking will go towards your grade next term, so if you can't get your book to me on Tuesday get it to me earlier, but whatever you do don't just NOT hand a book in.

You've been warned

Caesium and rubidium

well you asked for it...

Genes in America

Hi its me Naika from NY! Im here to tell you what another school is doing while your with your experiments. We're studing genes over here, and we've seen dominant and recessive genes and punnet squares and how to use them and figure out what genes the offspring could have. We're going to watch a national geografic video on sexual reproduction (after the school finishes editing it!).

Diary of... a y9 SCIENCE class - March 16th & 19th 2007

Hello,
Sorry for delaying my post about last class on Friday. But I'll talk about them in one post.

FRIDAY:
We started talking about metals reacting in water and did some exercises. We also did four experiments: reacting calcium powder in cold water, reacting magnesium strip with cold water, reacting calcium powder with hot water & reacting magnesium strip with hot water. The reactions with magnesium were a bit boring, almost nothing happened. But with calcium.... it actually blew up when it reacted. But thinking about this: in a previous experiment Andy didn't give us powdered magnesium because it was dangerous, and now: he gives us powdered calcium which is really more reactive than magnesium. We could accidentally have thrown some in the Bunsen burners (some people maybe not accidentally - not me, I'm not that stupid)!!!!!
Andy?????

Well, let's continue with today's class (MONDAY):
Today we talked about the reactivity series. And Andy, to demonstrate the order in the RS, did some amazing demos: he first reacted calcium with lots of water with universal indicator, it wasn't a very entertaining reaction, but... We still had to see the next ones. Secondly, he reacted sodium with water and universal indicator, wow! it gave lots of hydrogen. But the next one was, without any wonder, the big winner: He reacted potassium with water and universal indicator: it immediately exploded and went on fire, burning all the huge amount of hydrogen which was being produced. With the last one, Andy didn't need to do the hydrogen test, it was already taking place. The universal indicator was added to prove that an alkaline product was given off: the metal hydroxide. That's why these metals and the ones in the same group in the periodic table (group 1) are called: alkaline metals.
Well: that was all.

Don't forget that we need to do at least half a page about properties of the metals in group two (alkaline earth metals).

See you next time.

Want to know what happens when you burn calcium?

Wow! It melted the test tube!

And how could these children have seen this without getting blind?

Andy: now you know without doing it. Although... it doesn't look very dangerous.

Practice makes perfect

I was looking today for an old book that I used when I was studying GCSE - it was a great book just FULL of questions that was perfect for studying and practising and I found it - it's this one.



I suggest that, especially if you're in year 10 you get your hands on a copy of this - it's a great thing to own and to practice.

Also, if you're having trouble with any of the topics we are studying I would suggest CGP revision guides and practice questions.

You can find these on www.cgpbooks.co.uk

Diary of... a y9 SCIENCE class - March 15th 2007

Hye guys,
Today we didn't do alot: we did some exercises about metals reacting in water and we talked about The Bread. Have any of you smelt it? Disgusting! And it is not even green! The expiry date was the 27th of January!
Anyway...
bye.

P.s.: Andy, if we did today the exercises of metals reacting with water, are we going to do next lesson the famous amazing explosion?

haha! Nice try year 10

To those of you retaking the test tomorrow, just a quick note to say that it will be completely different to the one that you sat last time, but still on the topic of energy and force.

The reason?

Someone decided to leave the room with one of the test papers at the end of the lesson, so I've had to write another one. Just so that whoever took the test doesn't revise the answers.

I know who it is.

So a completely different test, all on the same topic and you will be expected to get over 50%.

Good luck!

Diary of... a Y9 SCIENCE class - March 12th 2007

Hello,
Today Andy gave us back our tests corrected. I hope everybody got a good grade.
After that, we started the new topic. We also did an amazing experiment: we got a little piece of sodium and threw it a big glass bottle with some water in it. It started fizzing. Andy, then, covered the bottle so that the hydrogen produced didn't escape. We then litted it with a match. A flat flame appeared going downwards inside the bottle and it made a very strange squeak which longed for more than a second. It longed much more than the hydrogen we did reacting a metal with an acid as we produced much more hydrogen.
Bye.

Next units

Pretty much all my classes had tests this week so you will now be moving on to the next units. These are as follows:

Year 7: 7I: Energy Resources, from page 99
Year 8: 8G: Rocks and Weathering, from page 75
Year 9: 9F: Patterns of Reactivity, from page 67
Year 10: Thermal Effects, from page 97

It is unlikely that I will be able to get another test in before the reports are due, which means it is even more important when studying these units that you do good classwork, homework and experiment write-ups and pay attention to the deadlines, because this is the only way you will be able to improve your report grade.

Remember, books not handed in by the deadline for whatever reason will not be marked and attract an automatic zero.

Reminder - year 11 books in on Wednesday

That means YOU!

Girls in science site

I just got sent a link to a science girls site thing. It's called Girls go Tech and you can reach it by clicking here

Lighting a match with steam

Useful for showing that steam has a higher temperature than 100 Celsius and also that steam has kinetic energy.

andy, i don't really understand a question from the quiz.

andy, when it said on the question... if the cat was dropped from the 6th floor, when would it hace half of its kinetic energy, is that just halving the number of the floor?, or is it a trick question?
and another one. the question about the men lifting bricks. how would you know which one does more power, because they don't give you any magnitudes to have you calculate...
meli

Want to learn stuff but can't be bothered to read?

I was just trawling the website of my old university and found some really interesting podcasts by leading academics. They talk about really interesting issues that may be very relevant to any subject you are studying in school and the people that record these are world-renowned professionals in many cases.

You can check out the podcasts by going to http://www2.warwick.ac.uk/newsandevents/audio/

Year 10 you may find the one about the nuclear energy debate useful - especially Melissa after our chat.

I think that a lot of the boys will appreciate the one on football management decisions and people into Terry Pratchet books will appreciate the one on the Science of Discworld

And the best thing about it? No reading - you just put it on your MP3 player and listen!

Energy Resources Yr10

You can see on the BBC website, Renewable Energy is a big issue in todays society

Yr 7 and Yr8 tests also reset

As with yr 10 yr8 and yr7 tests have been reset to allow you to do them again over the weekend at home.

http://quizstar.4teachers.org/

Year 10 - quizzes reactivated

I've reset the quiz that you took today in class to allow you to use it for revision at home.

This means that now you can retake the quiz again, twice as before. At the end of taking it twice you will be given the answers.

Just an idea but I suggest that you change your password in the profile bit and also I suggest you take this on perhaps Saturday night and Sunday night after some revision to see how much you know after all that revision.

And yes the exam on Monday will be as hard as this and maybe even harder. It's a test to see how much you know. No trick questions just good solid physics questions.

Good luck!

To get to that test go to http://quizstar.4teachers.org/

Oh yeah I've also added a test I made for year 8 once about forces to help you revise what a force is - Thought it may be of some use.

science games can be found in this webpage

Year 10 Revision Quiz lesson

In this lesson you will be taking a quiz to help you to revise for the test on Monday.

To take the quiz, click here to go to the Quizstar site and log in with the details that Andy has given you.

You will be asked to take the quiz up to two times. The first time you can't use your books at all and this will show you how much you know at the moment and how much you need to revise. When you complete the quiz you will be given a grade immediately.

The second time you may use your books.

In each case you are permitted to use a calculator.

If you manage to finish early then I want you to research only ONE piece of information on James Joule and post it on the Forum. You MUST post a different piece of information than everyone else! THis way we'll slowly build up a profile of this man piece by piece. So no wholesale copy and paste, just a single sentence on him.

Good luck!

Year 7 - Milk

Year 7 - Can we stop making the mistake of saying that milk is a solvent - it is a mixture of lots of different things in solution!

Thanks I just wanted to get that off my chest...

Year 10 - Various tests

I've just found this link to lots of online quizzes you can take in preparation for the test on Monday and the quiz tomorrow. Why not try them by clicking HERE

Year 7 Solubility revision test

If you want to take a quiz in preparation for the test on Monday, try the one on the BBC website, found by Ariadna

Just click here to take this quiz!

More quizzes on the same topic can be found here

This topic is ALSO relevant for the year 9 test tomorrow!

Year 7 Computer lesson

Today you will be taking an online quiz in preparation for your test on Monday.

To access the test you need to go to the Quizstar site and log on using the login name and password I have given you.

The quiz is multiple choice and you will be asked to click the correct answer for 20 questions.

At the end of the quiz you will be given your mark straight away.

You will be expected to take the quiz twice. The first time I expect you to take the quiz with no books open and without talking to anyone else about it.

Once you have taken it once, return to the start and take it again, to try and improve your grade. The second time you may have all your books open and you may discuss.

Once you have finished the quiz, I expect to see you revising for your test on Monday not wasting time.

Genetics

Chemical Reaction

A chemical reaction is a process that results in the interconversion of chemical substances . The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are characterized by a chemical change, and they yield one or more products which are, in general, different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions. On the classical definition, therefore, there are only two types of chemical reaction: redox reactions and acid-base reactions. The former involve the motion of lone electrons and the latter of an electron pair.

Different chemical reactions are used in combinations in chemical synthesis in order to get a desired product. In biochemistry, series of chemical reactions form metabolic pathways, since straight synthesis of a product would be energetically impossible in conditions within a cell. Chemical reactions are also divided into organic reactions and inorganic reactions.

Some reaction are:

• Isomerisation, in which a chemical compound undergoes a structural rearrangement without any change in its net atomic composition; see stereoisomerism
• Direct combination or synthesis, in which two or more chemical elements or compounds unite to form a more complex product:

N₂ + 3H₂ → 2NH₃

• Chemical decomposition or analysis, in which a compound is decomposed into smaller compounds or elements:

2H₂O → 2H₂ + O₂

• Single displacement or substitution, characterized by an element being displaced out of a compound by a more reactive element:

2Na + 2HCl → 2NaCl + H₂

• Double displacement or coupling substitution , in which two compounds in aqueous solution (usually ionic) exchange elements or ions to form different compounds:

NaCl + AgNO₃ → NaNO₃ + AgCl

• Combustion, in which any combustible substance combines with an oxidizing element, usually oxygen, to generate heat and form oxidized products. The term combustion is used usually only large-scale oxidation of whole molecules, i.e. a controlled oxidation of a single functional group is not combustion.

C₁₀H₈+ 12O₂ → 10CO₂ + 4H₂O

CH₂S + 6F₂ → CF₄ + 2 HF + SF₆

The cork in bottle

The Cork OFF The Bottle Trick - The best video clips are here

I told you it could be done! And well done to year 9 for doing it too, although this guy makes it look a lot easier doesn't he!

Diary of... a Y9 SCIENCE class - March 5th 2007

Hello guys,
Today we started revising the properties of metals and non-metals and ways of separating a metal from its ore (Electrolysis, displacement & smelting) because in the quiz we did on quizstar we were asked about them and some went: "¡UH?!" (We haven't done yet, so...).
Andy explained us how electrolysis work with a little experiment: having electricity go through a solution of salt in water. Chlorine gas and sodium were produced, but sodium reacted very quickly with the water producing sodium hydroxide. We couldn't smell the chlorine because it is a poisonous gas (the nazis used it in concentration camps), so be careful if you do it at home!
We also did something that isn't related to the topic: Who to get the cork out of an empty wine bottle? We used a plastic bag. We stuck it inside the bottle except for the mouth, we blew the bag up and then took the bag out and... the cork went out with it!
Today's was a fun class indeed.
See ya'.

DNA

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and functioning of living organisms. All living things contain DNA genomes. A possible exception is a group of viruses that have RNA genomes, but viruses are not normally considered living organisms. The main role of DNA in the cell is the long-term storage of information. The genome is often compared to a set of blueprints, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information.

In eukaryotes such as animals and plants, DNA is stored inside the cell nucleus, while in prokaryotes such as bacteria, the DNA is in the cell's cytoplasm. Unlike enzymes, DNA does not participate directly in most of the biochemical reactions it controls; rather, various enzymes act on DNA and copy its information into either more DNA, in DNA replication, or transcribe and translate it into protein. In chromosomes, chromatin proteins such as histones compact and organize DNA, which helps control its interactions with other proteins in the nucleus.

DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases, and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. Some RNA copies are used to direct protein biosynthesis, but others are used directly as parts of ribosomes or spliceosomes.

Animal Cell

An animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical. Human cells are biologically categorized as animal cells.

Cytoplasm
All cells consist of a jelly-like substance called Cytoplasm.The cytoplasm allows substances such as food and oxygen to move around within the cell take place in a cytoplasm .

Cell membrane
Surrounding the cytoplasm is a soft and thin cell membrane.The cell membrane holds the cytoplasm inside it. It also controls substances that go in or out of the cell.

Nucleus
In both plant and animal cells, there is a nucleus found in the cytoplasm. The nucleus is a very important part of a cell. It controls everything that happens inside the cell.

Year 8 computer lesson

I presume everyone saw the lunar eclipse on Saturday night - magnificent huh!

Anyway in todays lesson you will be doing a multiple choice quiz online to help you to revise for the end of unit test.

Unfortunately due to circumstances beyond my control, the test cannot be held on Thursday (you'll see why) but, will have to be held first lesson next week for each class, i.e. Monday 8C and Tuesday 8P.

This does mean that this week will be rather dull revision I'm afraid but this is beyond my control.

In todays lesson you will take an online quiz using a site called quizstar

I have written the test by looking at the chapter you have just studied, but not the test paper, as this would influence the questions I write. The questions I present here give a broad idea of the type of information you need to know, but I can't say if it has any resemblance to how the final test will look.

You will have 2 goes to complete the test and a maximum of 20 minutes each time.

Initially, I want you to do it with no book to see what you get.

At the end of the test, the computer will work out your grade straight away and you will be told what you got.

After your result comes back, you may do it again one time with your book open.

In each case you must not talk to anyone about it, as this is under test conditions to help you to practice.

Because this is under test conditions usual test rules apply. These include:

No talking
No using msn or email to communicate. If anyone is caught with any other windows open during the session they will be taken off the computer immediately no argument heard and will not be allowed to take the practice test.

You have been warned.

At the end of the test when you finish you need to go to the Science Heaven Forum Year 9 Page

On there, I want you to write a limerick about ANYTHING YOU HAVE STUDIED SO FAR.

Limericks are 5 line verses where the first and second line rhyme with the fifth line and the second and third line rhyme with each other.

An example of a limerick would be

There was a young man from Dealing
Who caught the bus for Ealing.
It said on the door
Don't spit on the floor
So he jumped up and spat on the ceiling

or

A mosquito was heard to complain,
'A chemist has poisoned my brain!'
The cause of his sorrow
was paradichloro-
triphenyldichloroethane.

or

The soil had so much uranium
It killed my prize geranium.
It would have won shows
But now it just glows
Enough to light up a stadium

You may have noticed, that limericks have a certain pattern to them that looks a bit like this

d'DAH-dah d'DAH-dah d'DAH (dah)
d'DAH-dah d'DAH-dah d'DAH (dah)
d'DAH-dah d'DAH
d'DAH-dah d'DAH
d'DAH-dah d'DAH-dah d'DAH

So I'd like to see at least one limerick from everyone by the end of the session. You will need to join the forum before you can post, and the link to join is up the top of the forum somewhere.

I shouldn't see any other windows open other than this one www.scienceheaven.com, quizstar, and the forum

Enjoy!

Comets

A comet is a small body in the solar system that orbits the Sun and (at least occasionally) exhibits a coma (or atmosphere) and/or a tail — both primarily from the effects of solar radiation upon the comet's nucleus, which itself is a minor body composed of rock, dust, and ice. Comets' orbits are constantly changing: their origins are in the outer solar system, and they have a propensity to be highly affected (or perturbed) by relatively close approaches to the major planets. Some are moved into sungrazing orbits that destroy the comets when they near the Sun, while others are thrown out of the solar system forever.

Comets are usually discovered visually or photographically using a wide-field telescope or other optical means of magnification, such as binoculars. However, even without access to optical equipment, it is still possible to discover a sungrazing comet online with a computer and an Internet connection.

Most comets are believed to originate in a cloud (the Oort cloud) at large distances from the Sun consisting of debris left over from the condensation of the solar nebula; the outer edges of such nebulae are cool enough that water exists in a solid (rather than gaseous) state. Asteroids originate via a different process, but very old comets which have lost all their volatile materials may come to resemble asteroids.

Year 9 Test dates next week - Friday test NOT Thursday

Unfortunately (for me) I can't set the test on Thursday so year 9 I had a choice to either do it Wednesday or Friday.

I realise that some of you have a French test that day, but the alternative is Wednesday and I'm sure that you won't mind the extra day study.

Good luck for FRIDAY'S test and don't forget you can use quizstar to help you revise too

Year 10 Homework - Due Wednesday

Your task is to summarise the works done in class on energy.

By Wednesday, I expect you to hand in an interesting summary of AT LEAST 2 A4 sides on the energy resources researched by your class in Fridays lesson.

Remember that you can still add to this information now. Make sure also that EVERYONE in your group has added SOMETHING - as I will also be checking to see that you have contributed to the research when I assign marks.

On top of this I expect to see the Brake Test worksheet done as I will be marking that and also I asked for the questions on Page 87, which after all that research, should be remarkably easy.

Looking forward to recieving your books, complete with your full names on them.

Electron Microscopes

Electron microscopes, which use beams of electrons instead of light, are designed for very high magnification usage. Electrons, which have a much smaller wavelength than visible light, allow a much higher resolution. The main limitation of the electron beam is that it must pass through a vacuum as air molecules would otherwise scatter the beam.
Instead of relying on refraction, lenses for electron microscopes are specially designed electromagnets which generates magnetic fields that are approximately parallel to the direction that electrons travel. The electrons are typically detected by a phosphor screen, photographic film or a CCD.

Two major variants of electron microscopes exist:

Scanning electron microscope: looks at the surface of bulk objects by scanning the surface with a fine electron beam and measuring reflection. May also be used for spectroscopy.
Transmission electron microscope: passes electrons completely through the sample, analogous to basic optical microscopy. This requires careful sample preparation, since electrons are scattered so strongly by most materials. It can also obtain detailed information on the sample's crystallography through selected area diffraction.

Virtual Lab

NASA has done a program which can be downloaded by clicking here. This program is called Virtual Lab, and consists of downloadable images taken with powerfull microscopes. There are alot of strange images you can download, as a water beetle.

Year 9 Computer room lesson 02 March 2007

In todays lesson you will be taking an online test using a site called Quizstar.

It is a multiple choice test and is just a practice test to warm you up for your test next week, which is next Thursday, the 8th of March. The test is not for me to judge you, but for you to judge yourself and to assess how much work you will need to put in to get a great mark next week.

I have written the test by looking at the chapter you have just studied, but not the test paper, as this would influence the questions I write. The questions I present here give a broad idea of the type of information you need to know, but I can't say if it has any resemblance to how the final test will look.

2nd March - Year 10 Group Research Exercise

As I mentioned yesterday, you will be doing your work today entirely online on the science forum, and hence you SHOULD have created yourself a profile so that you can post on there already.

If you haven't, you will need to do that before you begin, which will take about 5 minutes. You were told to do this yesterday, so if you haven't done so, and you don't know how, you will need to ask someone else in your group to help you.

Each group will be researching 2 different topics. The topics are:

Hydroelectric power

Tidal Energy

Wind Energy

Wave Energy

Geothermal Energy

Solar Energy

Biofuels

Saving energy

Fossil Fuels

Nuclear Fuels

There will be five groups that I assign (no you're not working with whoever you like) and each group will have 2 headings to research between them.

In your books, on pages 86-89, you have the bare minimum of information on these topics, but your task is to scour the internet and find out relevant information about all of these topics and present them to the class on the forum in a form that they can understand.

When you present information on the internet you must be aware of how it is set out and may need to consider a number of factors, like layout and structure of your information so that when you all post your information it doesn't turn into a big jumbled mess.

All of these topics are MUCH more indepth than the book lets on. For example you may want to look at the present state of each type of energy resource, how efficient it is, examples of where they are being used in the world at the moment, the history and development of each type of resource or the profits that can be made by each type.

This is not simply a cut and paste exercise, as every pupil can post on every other site and ask questions and the chances are I will be posting on the group sites and asking questions to see if you REALLY know what you're talking about or not.

So the task is pretty complex.

1 - you look up a good amount of information in your group on the subjects I set you

2 - you go and check out the other groups sites and test that they know their stuff too

3 - H/W - For homework you will be writing summaries in your books of each of the different types of energy resources, using the information gathered by the all of the groups. It must be at least 2 pages long.

So now it's up to you to get collecting and to start posting on the forum.

Diary of... a Y9 SCIENCE class - March 1st 2007

Hello,
Today was the day our books had to be given to Andy to be corrected, so, if you haven't give it... TOUGH!
We continued with the topic and did an experiment: reacting copper oxide and zinc oxide with sulphuric acid (not all in one test tube). It wasn't very "exciting" but it was OK because it is related with reactions.
That's all we did.
REMEMBER: next Thursday 8th we have the test about chapter E of our textbook and what we did in our notebook about reactions.
See you tomorrow.
