Can you rank these sets of quantities in order, from smallest to largest? Can you provide convincing evidence for your rankings?
Can you sketch graphs to show how the height of water changes in different containers as they are filled?
Can you place these quantities in order from smallest to largest?
This problem offers you two ways to test reactions - use them to investigate your ideas about speeds of reaction.
Is there a temperature at which Celsius and Fahrenheit readings are the same?
Many natural systems appear to be in equilibrium until suddenly a critical point is reached, setting up a mudslide or an avalanche or an earthquake. In this project, students will use a simple simulation game to investigate the properties of such systems.
Investigate how avalanches occur and how they can be controlled
Can you order pictures of the development of a frog from frogspawn and of a bean seed growing into a plant?
Can you rank these quantities in order? You may need to find out extra information or perform some experiments to justify your rankings.
This article for students gives some instructions about how to make some different braids.

Mathematics has allowed us now to measure lots of things about eclipses and so calculate exactly when they will happen, where they can be seen from, and what they will look like.
Mathematics has always been a powerful tool for studying, measuring and calculating the movements of the planets, and this article gives several examples.
