GCSE Biology Required Practicals is a collection of interactive required practical simulations designed to support the teaching of AQA, Edexcel, OCR, WJEC, and WJEC Eduqas GCSE specifications. This title is available as part of the Focus Science Online Resource Pack. See below for sample screenshots and a list of topics.
Microscopy
This experiment is about using a microscope to look at onion skin cells and estimate their size. The right hand side of the animation shows a 3D view of a typical microscope. The left hand side shows the view seen through the microscope.
Microbiology
In this experiment you can investigate the effectiveness of Penicillin in preventing bacterial growth.
Osmosis in Potato Chips
In this experiment you can investigate the effect of glucose solution on plant tissue, using a potato.
Effect of pH on Enzymes
In this experiment you can investigate how pH affects the time taken for the enzyme amylase to digest (breakdown) starch.
Food Tests
This Required Practical features tests for: starch, protein and sugar.
Photosynthesis
This experiment investigates how light intensity affect photosynthesis.
Reaction Time
In this experiment you measure your reaction time by catching a falling metre ruler.
Field Work
If you wanted to know the total number of daisies (or any other species) present in a field, it would be impossible to count every flower. However, you can estimate the total number of daisies present by using a quadrat.
Decay of Milk
This experiment models the decay of milk by using the enzyme lipase to break down the milk to fatty acids
Plant Responses to Light
In this experiment you can investigate how light affects the growth of white mustard seeds.
