Use a light microscope to observe, draw and label a selection of plant and animal cells.
Practical 2
Biology Only Investigate the effect of antiseptics or antibiotics on bacterial growth using agar plates and measuring zones of inhibition.
Practical 3
Investigate the effect of a range of concentrations of salt or sugar solutions on the mass of plant tissue.
Practical 4
Use qualitative reagents to test for a range of carbohydrates, lipids and proteins.
Practical 5
Investigate the effect of pH on the rate of reaction of amylase enzyme.
Practical 6
Investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pondweed.
