Today we will be finishing off for the year, as this will be your last year 8 Science lesson before the new timetable starts! Answer the following in your books:

1. What have you enjoyed about Science this year?
2. What would you have liked to change?
3. What do you feel you've got better at doing?
4. What are you most excited for about next year?
5. The last thing to do - and this is very important - is to try and find an activity or game that has something to do with Science from this year. It could be anything that you're interested in or even something that we haven't looked at in class - it just has to be related to Science! Send me the link if you find a good one, there will be achievement points for good resources.
6. Try any of the activities here to help you get started.

Choose one of the following chemistry topics we have covered and tell us all you know about it....

The fire triangle

Exothermic/Endothermic reactions

Fuels and combustion

Atoms and Elements

Compounds and Mixtures

Solids, liquids and gases

DONT PRINT your work, save it and we'll copntinue next week. Once you've finished and shown Mr. Perkins and Mr. Cole, try one of these activities:

Scientist Biography

Your job today is to produce a poster containing information about Joseph Priestley or Dmitri Mendeleev which other Year 8 students can use to learn about the people who have shaped our lives.

Use the internet to find information about the following points and create a powerpoint with it:

Things to include:

Name

Picture

When did they live?

8A3 CHEMISTRY- 23/5/12

1. Write down the fire triangle (fuel, air, and heat supply) from the video you have just seen of a hybrid rocket:

2. What is combustion?

3. What is a fuel? List as many fuels as you can find.

4. Which gas in air is needed for burning?

5. What is an exothermic reaction?

6. Hydrocarbon fuels contain atoms of hydrogen and carbon. When hydrocarbon fuels combust, energy (heat/light), water and a gas is given off. What is this gas?

7. Petrol used in cars is an example of a hydrocarbon fuel. What happens to the petrol in our cars?

8. Methane is the gas fuel we use in our Bunsen burners at school.

a) Where does the fuel come from?

b) Where does the air come from?

c) Complete the equation for the combustion of methane gas.

Methane + oxygen -->

9. Try and write a balanced chemical equation for this combustion reaction. (Hint methane= CH4)

10. Can you balance the equation so both sides have equal atoms of each element?

8A3 CHEMISTRY- 9/5/12

1. What is an element? Give an example

2. What is a compound? Give an example

3. What is a mixture? Give an example

4. Give 3 properties of metal elements?

5. Give 3 properties of non-metal elements?

6. It is important to get chemical symbols correct! CO is the symbol for Carbon Monoxide and Co is the symbol for Cobalt!  What is the correct chemical symbol for magnesium?

 Mg        MG        mG         mg

7. What is the chemical symbol for oxygen?

8. Magnesium and oxygen are the two reactants for the combustion of magnesium. Write down the word equation for this chemical reaction including the reactants and final products.

9. Do you think the mass of magnesium oxide is lighter, the same or heavier after the magnesium is burned? Explain your answer?

10. What does the periodic table represent? Is it a table of elements, compounds or both?

When you have finished the quiz:

Revision for Monday

Sorry for the delay in posting this, here's what you'll need to remember for the test tomorrow:

1. What the three rock types are and how they are formed (sedimentary from layers being deposited on lake or ocean bottoms, igneous from lava or magma cooling, matemorphic from other rocks being put under heat and pressure)
2. What dangers are created by volcanoes (lava, ash, volcanic bombs) and why they look different from each other (the viscosity of the lava they are made from)
3. What problems are involved with buildings made of limestone (being dissolved by acid rain).  The video below this post is worth watching to help you with this.
4. What fossils are and why they are important (dead organisms buried in sedimentary rock, can help Scientists find out about the past).

Make sure you use the other links on this page to help you revise - the 'rockhounds' site from question 2 on the 28th of Feb. has lots of good information. 

There will also be a little bit of time before the test in class for anyone to ask any questions they aren't sure about.  Make sure you bring in your revision sheet to help you just before the test.  Good luck, see you tomorrow!
