Required Practical - Rates of Reaction (AQA) - Changing Concentration

This gives a one sheet document that can be printed out and used by the class to complete the required practical. There is a sheet for both part 1 (disappearing cross) and part 2 (volume of gas). For part 1 I have included two options - the second slide is my preferred option and gives the students more guidance (this is the hand out that I used and it goes well along with the power point). Covers hypothesis, variables, the purpose of each step and conclusions. If you are only carrying out the disappearing cross practical then diagrams of the other possibilities are used in the plenary.
