Activity 1
Begin by checking some general concepts. Look at these links on Systems and Cell Processes. Work in pairs to answer the questions below. Answer the questions on a sheet of paper.

1. What is a system?
2. Name at least three different systems found in the ‘Systems’ link
3. Why can’t systems work alone?
4. What is excretion?
5. What are the two types of respiration?
6. How do plants make their own food?
7. Can animals make their own food?

Check your answers with your teacher.

Activity 2
Now you are ready to work in teams. Form groups of three and choose your topic. There will be more than one team researching each topic.

• Team 1 will research animal digestive systems
• Team 2 will research respiratory systems
• Team 3 will research plants

Read the instructions for the website for your topic. Then click on the link under the image to visit the website and take notes.

Team 1 Animal Digestive Systems
Digestion	Digestive systems of different animals	The flow of energy through plants and animals
Read: ‘Animal digestion: Herbivores & Carnivores’. Write down 3 important things.	Read these sections: ‘Digestive Systems in different Animals’. Choose 3 animals and write down 3 important things for each animal.	Read: ‘Picture of a Food Chain’. Write down 3 important things.

Team 2 Respiratory Systems
Respiratory systems in different animals	Respiratory System	Respiratory System
Read: ‘External Respiration’. Note down 3 important things.	Read these sections: ‘Respiratory System-All about breathing’; ‘What does this system do?’, and ‘Interacting with other systems’. Write down 3 important things from each section.	Read these sections: ‘Respiratory System’ and ‘Gas Exchange’, ‘Bodies and Respiration’, ‘Methods of Respiration ’and ‘Respiratory Principal’. Write down 3 important things from two of the sections.

Team 3 Plants
Video on Photosynthesis	How plants and animals differ	Photosynthesis
As you watch the video, complete this worksheet.	Read the chart explaining the difference between plants and animals. Write down the most important points.	Read ‘Photosynthesis is for the Birds-and Everything Else’ Write down 3 important things.

Now move on to Task 2 or see the Other Resources below.

Take a look at these additional links if you need more information

• Closed and Open circulatory systems
• Stages in the Digestive process: In this link only read the section ‘Stages in the Digestive process’.
• Digestive Systems: This covers vertebrates, sharks, birds, rabbits, horses, koalas, cattle, deer, sheep. The descriptions are brief, but there are some good line drawings of the digestive systems.
