Our first topic in Biology is ''Food Tests'' The molecules that make up the bodies of living things are introduced in this topic, and will be referred to in all of the subsequent units.
This unit starts by considering the molecules from which living organisms are made, and then looks at food sources for animals and their necessity to build up the structure of their bodies, and also to supply energy.
This unit also provides opportunity for students to improve their practical skills. Practical work in this unit includes :
Scientific Enquiry work focuses on:
