Extraction of metals

This piece of work should be up to 2 pages long.

Remember to use diagrams and pictures where this is useful.

You need to cover the following points

Examples of ores

• Why most metals are not found “native” (which are?)
• How metals are extracted showing a range of methods to include both the smelting of iron ore (show a blast furnace and what happens) and the electrolysis of aluminium (keep to the general principles – don’t get bogged down in the chemistry)
• When the metals were first identified (stick to ones we use in class – copper, iron, aluminium etc)
• Uses of different metals.

The piece of work needs to cover:

causes of rusting (oxygen, water also effect of heat and salt solution)

how to prevent rusting (include painting, galvanising)

why is rust a problem (think of the strength)

Include pictures as well as written info. Strictly no copy and paste of text.

One side A4 max.

You will be researching about fossil fuels. You need one side of A4 maximum.

Include:

• how fossil fuels are formed (need a diagram which you explain)
• the 3 types of fossil fuel (an include pictures)
• briefly - how we get the fuels
• any issues you an find out about them (e.g. how much is there of each, pollution).

Remember not to copy and paste text - it will be deleted!

Plant Life Cycles

1. Before starting this lesson you should make sure that you have your exercise book, a pencil, a rubber, a pen and a ruler. If you don't please ask one of your friends if you can borrow equipment and go back to the classroom to get your book.

2. Click here and watch the video and complete all the tasks within the video.

3. Once you have finished watching the video and finding all the ways that seeds can be moved around click the link below and read all 8 of the information pages (use the next button at the bottom of each page to move on) http://www.bbc.co.uk/schools/ks2bitesize/science/living_things/plant_life_cycles/read1.shtml

4. On a fresh page in your book put the title ' Life cycle of a flowering plant'

Using approximately half a page draw the flower diagram from page one of the information notes and label each part of the flower.

Using the other 7 information pages write a short paragraph of notes explaining each of the sections of a flower

Example

Receptacle

This is the top of the flower, where it attaches to the stalk. All parts of the flower attach to it.

5. Finally using what you have learnt and the information available in the video and the information pages write a short paragraph of notes explaining 'How Seeds are Made'. Choose an appropriate title for this section yourself.

6. Having watched the video, read the information and taken some notes, test yourself on the quiz below

7. BBC Bitesize can be used to help you with your revision for topics that will be tested in the summer Exam. You can use BBC Bitesize in the same way as you just have done for any topic that we have covered. Use the time left in this lesson or at home to revise another topic by watching the video, reading the information pages, making some notes and finally testing yourself.
