Complete lesson with an interactive PowerPoint (I use mini-whiteboards for Q & A sections), full lesson worksheet for 6 common experiments (see below) and extra assessment worksheet.
I'm really proud of this lesson - like all my resources I've used it numerous times successfully and I'm confident your students will enjoy and learn as much as mine did. Let me know how you get on!
1. Discussion exercises leading to the definition of a chemical reaction
2. Teacher led instruction introducing the criteria for a chemical reaction
3. Discussion exercises about whether ice melting is a reaction, leading to the differences between reactions and physical changes
4. Six quick experiments that allow pupils to see the differences between reactions and physical changes
Chemicals required for practicals:
Chalk and dilute acid (HCl)
Teachers are advised to risk assess and practice any experiments in advance.
If used please provide feedback to direct future resources. Thanks
