Before you start: what do you predict will happen? Why?
What you do
| Step | What I observed | |
|---|---|---|
| 1 | Add magnesium to beaker 1. | |
| 2 | Add zinc to beaker 2. | |
| 3 | Compare the highest temperatures. The bigger the difference in reactivity, the more heat. |
Questions
- Write a word or symbol equation for one reaction you observed.
- Explain your most important observation using particles, ions or energy.
- Was your prediction right? What would you change to get a more reliable result?
