Two pictures showing pollution with 10 differences. Simple starter for a low ability class.

Powerpoint explaining hydrogen bonding. OCR A spec. Answers to starter: Van der Waal Forces Permanent Dipole Ionic

A lesson plan for a lesson on precipitation reactions to form soluble salts, along with a worksheet for pupils to complete, and a PowerPoint to explain the process.

Pupils cut out the 16 squares and sort into 4 piles - acids, bases, salts and water. They then use these to form neutralisation equations. These can then be stuck in books with + signs and arrows added to form correct word equations. Good for helping pupils to understand how to name salts.

Students are in pairs. One person in each pair is facing the board and the other is facing away from the board. The person facing the board has 30 seconds to describe the key word before the slide moves on, without mentioning any of the "taboo"
