<p>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.</p> <p>The worksheet is laid out in the form of SOLO taxonomy; and answers are given at the end.</p> <p>The four graphs used are taken from AQA past papers and practise questions.</p> <p>Any feedback is greatly appreciated.</p> <p>Thanks, Michelle.</p>

<p>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.</p> <p>There are two documents included; the first with the equations only, and the second with the equations and the answers included.</p> <p>Please provide feedback with how this resource can be improved.</p> <p>Many thanks.</p>

<p>Ideal for all areas of science, covering units from giga- to nano-</p> <p>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.</p>
