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:

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.

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.
