Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about chemical reactivity and chemical change (GCSE and Key Stage 3)
I was sent this epic video showing a chemical party and just had to share it. It includes lots of nice ideas that you could modify and use in your classroom, but you will need to watch it first. I will add some more resources on chemical reactivity here shortly.
Chemical or physical change in the context of rusting
Key Stage 3 worksheet on chemical and physical change looking at rusting. Students take a nail home and have to make it rust! Students bring the nail back two weeks later and this can serve as a platform to begin thinking about chemical and physical change. (PDF)
Reactivity of metals
This activity asks students to measure the temperature change when pieces of magnesium are added to acid. Students plot a simple graph of their repeated measurements to help them visualise exactly what is meant by reliable data. This investigation could be easily adapted to investigate the reactivity of different metals (e.g. zinc, copper, iron and magnesium) by comparing temperature changes. This would make an excellent inquiry.
