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!
