This is a three page SOLO worksheet aimed at helping foundation pupils to understand and use graphs to determine radioactive half-life, in the topic of Atomic Structure. Pupils give the definition of half-life, before stating how to determine half-life from a given graph, then using four graphs to practise determining half-life, and finally drawing their own half-life graph. The worksheet is laid out in the form of SOLO taxonomy; and answers are given at the end. The four graphs used are taken from AQA past papers and practise questions. Any feedback is greatly appreciated. Thanks, Michelle.

A collection of 62 chemical equations for students to balance. Differentiated into four categories of difficulty. These will come in useful for KS3, KS4, and the basics of KS5 Chemistry. There are two documents included; the first with the equations only, and the second with the equations and the answers included. Please provide feedback with how this resource can be improved. Many thanks.

Ideal for all areas of science, covering units from giga- to nano- Some students can find converting units difficult, but practise makes perfect. Over the past few years I have found that this help sheet helps in the early stages of GCSE and learning/practising this skill.
