Understanding particle theory is fundamental to science; it's so important that students have a really good understanding of it. This activity is designed to make students really think through these important ideas before they record what they have discovered.

This hands-one, minds-on activity is designed to get students thinking about the differences between atoms and molecules. It is backed up with a student worksheets which gets students thinking even further. Molymod (or equivalent) models are required. Although this activity is aimed primarily at KS3 students, GCSE students are likely to find it helpful too.

This card game is based on rummy and is designed to help students understand how salts are made when an acid and alkali react. Points are scored when a complete set of chemicals is collected. The game can be followed with a student worksheet developing ideas about neutralisation.

Here are two activities designed to help students understand the significance of elements and investigate some of their properties. The activities are backed up by a student worksheet. It is primarily aimed at KS3 students though teachers might like to use it with less able KS4 students too.

So many students find this topic confusing! This resource is intended to make clear the differences between atoms and molecules and between elements and compounds. The practical work is backed up by a student worksheet. It's primarily aimed at KS3 students but weaker KS4 students will find it helpful too.

This is a suite of materials containing a number of different activities. It starts with lots of fun mini experiments where students record the differences between them. Their results are used to examine the differences between continuous and discontinuous variation. Variation in other species is examined too with an emphasis on data handling.

It's hard to find much practical work to do around food chains. Here's a very active demonstration that turns into a student race and brings home all the key ideas that students need to understand. It's accompanied by a crossword puzzle.

This group of activities provides a fun and active way to introduce cells including building squidgy model cells. It includes investigative work to find out the conditions that cells need to grow best. All the activities are backed up by student worksheets.

Here students consider the genetic and environmental causes of variation by building a model human. Students enjoy making the models which make clear the different types of variation. There is a worksheet to use as a follow up to the activity which extends the key ideas and promotes thinking.

A fun role play activity to help students understand the concept of bioaccumulation. There's also a worksheet for students to complete which consolidates the concept. Students of all abilities will be able to take part
