AQA practicals – effect of gravity on seedling growth (not combined science)
Investigate the effect of light or gravity on the growth of newly germinated seedlings.
Observations of biological specimens to produce labelled scientific drawings.
Record results both as length measurements and as accurate, labelled biological drawings to show the effects.
Use appropriate apparatus to record length and time.
Selecting appropriate apparatus and techniques to measure the growth of shoots or roots.
Safe and ethical use of plants to measure physiological function of growth in response to light or gravity.
Plan experiments to make observations to explore the phenomena of plant responses.
Apply knowledge of a range of techniques, apparatus and materials appropriate to the experiment.
Make and record observations and measurements using length and biological drawings.
Suggest improvements and further investigations.
Present observations as tables, graphs or drawings.
