The relationship between energy and states of matter is sometimes difficult for students to comprehend. This activity helps to reinforce the notion that, when energy is added to a system, the molecules themselves do not change but their motion and relative positions do change.

While the model is a...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to introduce the idea of solubility. Solubility is the amount of a substance that will dissolve in a certain amount of solvent.

This progression toolkit develops understanding of the key concept of solutions, as part of a topic on substances and mixtures. This key concept helps to build broader understanding about substances and properties, which is one of the big ideas of science education at ages 11-14.

It includes diagnostic...

Produced by the Learning and Skills Improvement Service (LSIS), these resources are aimed at mathematics practitioners.

In this resource, sessions look at:

• Solving simple equations (encouraging reasoning rather than 'answer getting')
• Rearranging simple equations (encouraging reasoning...
