Designed for AQA C2, this is a structure and bonding task, including polymers. Each pupil has a sheet, and they have to go around the class and find different people that explain the answer to each question. Kind of like bingo. Then once someone has finished they come to you, and in front of the class have to answer random questions from the grid correctly to win.

I used this as a stretch activity for top year 10's. It is a problem solving activity that requires an understanding of the concepts of ionic and covalent bonding. Encourages pupils to apply their knowledge! ( The answers are X = Sodium, Y = Carbon and Z = Chlorine). P.S. I know that some of the statements are not necessarily true, but they are for the purpose of GCSE chemistry!

This tarsia covers a variety of chemical word equations - designed with OCR 21st century science C6 in mind. If pupils finish it quickly you could extend by getting them to write balanced symbol equations for the word equations in the tarsia.
