A cut and stick diagram to help students think through the rock cycle plus a worksheet about the three main types of rock.

In my experience (over 20 years!) this method of explaining how to balance equations has never failed. That's a bold claim but students unfailingly enjoy this activity and find it really helpful . Note that a molymod molecular model kit (or similar) is required. Also included are a two worksheets which allow students to practise writing equations without the models.

This suite of materials is designed to lead students through the details of ionic compounds The atoms and ions worksheet helps students understand how ions are formed from atoms. Follow it up with formulae activity where students where pairs of students have to work out the formula and the name of a compound formed from two ions randomly drawn from a pack. Finally, there's a worksheet with a structured, step wise approach to develop students ideas about ionic bonding.

This Venn diagram activity is ideal for diagnosing student misconceptions and helping them gain a really good understanding of collision theory. The statements that need placing have been chosen to prompt debate and discussion and it makes a great whole class activity. Although it was written for keystage 4 students it is also useful to use with keystage 5 students at the start of the topic. A second sheet gives the answers. There's a follow up worksheet to consolidate important concepts and a further colour in sheet exploring why chemists want to control reaction rates.

A lesson on the important difference between cause and correlation. The teacher notes give details of examples where there is a strong correlation but no causal link, examples which can be hard to think of on the spot! The presentation is based around air pollution and helps students to understand the key ideas. It can be followed up with the worksheet which includes many examples. For each example students sort the three options given into correlation, cause or no link

There are instructions here for a teacher demonstration comparing the oxidation of iron in air and oxygen. There is then a Venn diagram activity where students classify a series of chemical reactions - an activity designed to promote thinking and learning. Finally, there is a follow up worksheet that recaps the key ideas. Finally there is a presentation that gives a useful comparison of oxidation and reduction along with helpful definitions

A teacher led demonstration activity to help students understand how errors in measurement are inevitable. The accompanying worksheet allows students to record the errors as they occur in the demonstration and then provides an opportunity to think through what they learnt.

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.

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.

In this series of activities students analyse a sample of soil from Mars. The activities are straightforward and are designed to be a good introduction to practical work for year 7 students. The activities include testing for the presence of water, determining the acidity of the sample and examining the soil structure using a microscope. The sheet gives full details for teachers and technicians including a recipe for the Martian soil and there is a worksheet for students to complete as they go. Also included is a cut and stick Martian globe that students can make to fit around a tennis ball

UV reactive beads change from white to coloured when exposed to ultra violet light and are wonderful for teaching reaction rates (so much easier than trying to work out when the cross has disappeared!) They are genuinely suitable for use with any age group and the notes here give ideas about how to carry out investigations at different levels. Post 16 students can use these beads to find activation enthalpy with a convincing degree of accuracy.

A teacher demo is used to introduce some student practical work comparing, by measuring mass, the amount of sugar in different soft drinks. Students will need to draw up a calibration curve and the practical work will help to develop their ability to use a burette accurately.

A fun practical activity that introduces the idea about accuracy of measurement and using the appropriate piece of equipment. The teacher sheet is backed up by a worksheet for students. It is aimed at keystage 3 students but is likely to be useful for less able keystage 4 students.

Here are details of a practical investigation into the role of salt in preserving food that is simple to carry out and doesn't require much equipment. The results are quick and easy to analyse. To follow up there is a worksheet probing further into salt and human health where students calculate how much of the recommended daily intake is contained in various foods.

This resource gives full details for teachers on how to carry out three demonstrations with alkali metals. It should be helpful for new teachers or those teaching out of their specialism 1. observing and comparing with other metals 2 reaction with water- the straightforward demo plus two further enhancements readily carried out in the lab 3 reacting sodium with chlorine There is also a table for students to record their observations.

Here are teacher instructions for demonstrating three exciting exothermic reactions along with one that is endothermic. To follow up there is a student worksheet which introduces energy level diagrams.

This activity is the best method I've even found for helping students understand how to balance equations. In my experience, every child in the class, has been able to achieve success, even if it takes them longer than other. The activity requires at least a modest supply of molymod (or similar) atomic models. Two accompanying worksheets provide a structured opportunity to consolidate and stretch.

This is a great practical because students really will see the small beads of lead they create in the reaction. As well as details for the teacher and technician there is a worksheet for students that gives instructions as well as follow up work designed to help them think through the reaction. A foundation version of the student worksheet is also provided that may also be used with keystage three students.

A great practical activity for students who may be less academic; this experimental work will help students to see the relevance of chemistry to the construction industry. NOTE that access to a kiln (usually present in most secondary art departments) is required to make the bricks. There are instructions for making bricks and reinforced cement beams. Students then perform tests on the items they have made. There is follow up work provided on student worksheets

This is a role play activity to help students understand how electrolysis is uses to extract aluminium from aluminium oxide. It is designed to aid appreciation of the ionic nature of bauxite and assist the wring of ionic half equations. There is a follow-up worksheet to consolidate the key ideas.
