Acid Concentration and Metal Practical KS3

The powerpoint is very short but includes a practical based on 3 different concentrations of acids which are to be added to a metal. There is a section at the end of the lesson where the students have to write up their investigation from their equipment list, method and the analysis of their results. The write up has minimal support therefore would be perfect for a high ability class - however this has worked well for me in the past with low ability provided they are well trained in writing up investigations.
