topic 2: cells, tissues and organs

In Year 7 Biology you will learn about how we know if something is alive and what living things are made of. You will see how different living things interact together in their environment and what makes organisms the way they are.

If you think you know all about Year 7 Biology try this Year 7 Biology Mega Quiz. 

1.1 Explanations, argumentation and decisions;
1.2 Applications and implications of science: a) exploring how the creative application of scientific ideas can bring about technological developments and consequent changes in the way people think and behave; 
2.1 Life processes;
3.3 Organisms, behaviour and health: a) life processes are supported by the organisation of cells into tissues, organs and body systems
