This is a research based task designed for the C4 unit of Twenty First Century Science but could be used for any specification that looks at the periodic table.

A worksheet for GCSE about concentration and titration calculations with answers

This worksheets gives the formulae of some of the more common ions and their charges and requires students to find the right charges and combine them correctly to give the right formula.

A research based task on the development of the atomic model with success criteria. This has been commonly used as a bridging task from Year 11 into Year 12 Chemistry.

This worksheet is intended for use during or after a teacher demonstrates (or shows a video) of the reaction of lithium, sodium and potassium with water.

A two sided, differentiated by task worksheet based on atomic structure. Students see how far they can go and can easily identify what grade (approximately) they are working on.

Designed for GCSE Chemistry courses, this set of questions and success criteria require students to draw a graph of the boiling point of the halogens and then asks then increasingly difficult questions about the halogens. A simple success criteria is included.

This is a two-sided worksheet designed to help students studying the formation of salts from metals, metal oxides, metal hydroxides and metal carbonates. The first side deals with simple word equations whilst the second side covers more complex equations using formulas and balancing equations.

This is a simple game devised specifically for unit C3 of OCR Twenty First Century Science GCSE. Students are put into groups and play a simple decision making game about making and selling a perfume bottle. The aim of the game is to generate discussion and ideas around sustainability and life cycle assessments which can be a rather dry topic to teach. This game was originally published for free in 2008. It has been slightly adapted for the new (2012) specification.

This activity is designed for Year 12 students studying Chemistry. Rather than teach the students the rules and then give them some examples to work through, this activity encourages independent thinking and problem solving skills. The students are given some of the values for oxidation states and have to figure out the rules. The task has been differentiated by support by proving a list of rules that can be issued if a particular student or group is beginning to struggle.
