A3 posters

Today you're going to make a poster explaining the features of your animal. We're in the library so you can use the colour printer to create an eye catching poster to tell people about the adaptations your animal has. You need to work as a group to produce a poster showing:

• The name of the animal (species name, not what it's friends call it!).
• Where it lives.
• What it eats.
• What colour it is (and WHY).
• Any other adaptations it has.
• Why it is important to the ecosystem.

Cut out your sections from powerpoint slides and stick them on your poster. We will finish painting the animals next week and make a display in class with them.

Animal posters

Today you're going to continue planning your animals from last lesson, thinking about the structures that help them survive. Answer the following in your books, and remember you will need these next week!

1. What colour is your animal? How does this help it?
2. Does it gain or lose heat easily? Why is this?
3. Think about your animal's activity levels. Does it move quickly? What type of muscles does it need?
4. How does the oxygen your animals muscles need get into it's blood? Name one other place in the animal's body where diffusion occurs.
5. Draw a biomass pyramid containing your animal. Where does it fit in? What is the term for where it fits?                                                                        
6. Most living things are made from lots of carbon. What element makes up most of yours?  How does this benefit your animal?
7. Read about this lizard defending itself (a real story). Does your animal have any chemicals that help it stay alive?
8. Use this site to list five other adaptations of your animal. You should also explain how they help it:
9. Try this activity. Name one animal adapted to a desert environment:
10. Identify the organisms in this ecosystem, then place them into a food web:

revision

Today we're going to finish off revising for the test tomorrow in class. make sure you have your handouts from last week, and complete the following in your books:

1. What is conduction? Give an example:
2. What does heat transfer through during convection?
3. Explain how density relates to convection:
4. Where does radiation occur? Give an example and explain how it is different from the ther two heat transfer methods.
5. Why are metals good at conducting heat? Why ISN'T wood a good heat conductor?
6. What is a heat insulator?
7. What are the two ends of a magnet called?
8. What 4 metals are attracted to magnets?
9. Explain how you would make an electromagnet. How is this different from a normal magnet?
10. How can magnets be made to repel each other? How can they attract each other?
11. Extension - Do some reading and find out how maglev trains work. Why are they better than normal trains?
12. This video helps you look at examples similar to those we saw in class.
13. Finally, try this activity. Which charges attract and repel each other?

HOMEWORK - Read through these questions and your notes from last week, to mae sure you're ready for the test in period 2 tomorrow! Come and ask Mr. Cole beforehand if you have any questions.

Group presentations

Today we will be working in groups of two on presentations for tomorrow. They will go for no more than 2 minutes each and will deal with one question about this topic. Some will be about heating, and some will be about magnetism. The tasks for today are:

1. Organise a group of two and get a question from Mr. Cole.
2. Find information on the internet or in your books about your topic, and make sure you understand it!
3. Make 2-5 powerpoint slides about your topic, and write a script so you will know what to say. 
4. Practice your part so you know what to do, there will be prizes for good presentations!!

We will present these tomorrow in J18, so make sure you come on time. For homework, read over your section so you know what you will say in front of the class. 

Heating

Today we're going to keep working on ways that things can be heated. Answer the following in your books.

1. What needs to happen for conduction to occur?
2. How is the food on this bbq getting warmed? Name all three types of heat transfer here:

3. What is convection?
4. Why is a convection oven better at cooking? 
5. Watch this video. Explain how Heston uses conduction, convection and radiation to create the meal:
6. Think of your favourite hot food. Find a picture of it, and put it on a powerpoint slide. You need to use arrows and axplanations to show HOW the food is heated (by conduction, convection, radiation, or more than one) and where the heat comes from. Save this and we will print it if we can.

Homework:

For one meal you have this week, explain what you had which was cooked and how it was heated. Make sure you use thte terms from class today. Bring it in next week. on Monday.

Heating, cooling and magnetism

Today we're going to be working on the topics that we will continue with after half term - heating, cooling and magnetism. Answer the following in your books.

1. Watch this animation. What are the three ways that heat can be transferred?
2. Give three examples of conduction:
3. Which three metals can be used to make magnets?
4. How are magnets different to normal objects? Use this picture to help you explain:

   

   A magnet on the left, a non magnet on the right.

5. What is an electromagnet? Describe one and draw a diagram:
6. Watch this video, and explain where electromagnets can be useful:
7. Complete this sentence - 'Substances get ...............when they are heated and.................when they are cooled.'
8. Explain what happens to particles when they heat up. What problems can this cause with large objects like bridges?
9. Describe shrink fitting:
10. Try and finish this challenge!
11. Try this activity. What charges attract each other? Which ones repel?
12. One more activity if you finish early.....

Rocks and weathering revision

Today we will be starting to revise for the tes on rocks and weathering next week. Answer the following in your books:

1. What does limestone look like?
2. Using the link above, what sort of rock is it? (metamorphic, sedimentary or igneous?)
3. Explain one problem associated with building things out of limestone:
4. What will this lava form when it cools down?
5. What influences the size of crystals in a rock formed this way?
6. What is metamorphic rock?
7. Watch this animation ( http://www.bbc.co.uk/bitesize/ks3/science/environment_earth_universe/rock_cycle/activity/ ), and explain what you can often find buried in sedimentary rock:
8. Try this quiz, which is fairly similar to the questions you'll have on the test next week:
9. Use the rock cycle to explain how a sedimentary rock could become a metamprohic rock:
10. How would you describe weathering and erosion? Give two ways a rock can be eroded:
11. Try this quiz (it's pretty hard so don't worry if you get some wrong!).
12. Last of all, try and find out what coccolithophores are and what part or Britain they helped create.  There's an achievement point for anyone wo can do this!
