Here's a great GCSE science revision idea. Create Venn diagrams to help to visually represent the similarities and differences between two concepts.
Venn diagrams are named after British logician John Venn.
This example involves two sets, A and B, represented here as coloured circles.
The pink circle, set A, represents types of living creatures that are mammals. The yellow circle, set B, represents the living creatures that have wings. Each separate type of creature can be imagined as a point somewhere in the diagram. Living creatures that have wings and are mammals, for example, bats—are then in both sets, so they correspond to points in the region where the pink and yellow circles overlap. This overlapping region would only contain those elements that are members of both set A (mammals) and set B (living creatures that have wings).
There are lots of topics within GCSE science that you can create Venn digrams for. An example of a biology topic would be cells.
The diagram identifies the features of animal cells and plants cells with the overlap showing your knowledge of the similarities for the two as well.
For a chemistry topic, you could choose ionic and covalent bonding. Have a go before you look at the one below and then compare them.
How did you go?
Got the idea? Now try a physics topic. Let's have a go at comparing series and parallel circuits. Create your own and then compare with the one below.
Venn diagrams are a great way to get you to interact with your class notes or any other notes that you are using to study/revise from. They also check how well you have grasped the topics and will indicate if you need to do further work on that topic.
