Stretch and Challenge

Produced by Nelson Thornes, these materials are samples of their A2 level science resources. They are designed to support the AQA A2 specifications but samples and activities can be applied to the teaching of other courses. Activities cover chemistry, physics and biology and include teacher notes as well as student sheets. The topics covered include:
• Born-Haber cycles
• Drug synthesis
• Reaction rates and mechanisms
• Redox titrations
• Rusting
• Carbon fixation
• Gene therapy
• Kinetic theory
• Selection and speciation
• Energy conservation
• Organic farming

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
