1. A metal statue stands in an industrial city. The rain is acidic because of the pollution in the atmosphere. What will happen to the statue over time?

2. How quickly the reaction happens is called the rate of the reaction. What variables could affect the rate of this reaction?

3. The statue is going on a world tour. You will work as a class to investigate how the temperature of the acid rain would affect the rate of the reaction. You will be using magnesium ribbon and hydrochloric acid. What is the word equation for this reaction?

4. How are we going to measure the rate of the reaction? Hints: What will happen to the piece of magnesium? What will be given off during the reaction?

5. Variables… The independent variable (the thing we will change) is… The dependent variable (the thing we will measure) is… The control variables (the things we will keep the same) are…

6. Team Iceland 0ºC

7. Team Russia 10ºC

8. Team UK 20ºC

9. Team UK 20ºC Team France 25ºC

10. Team Italy 30ºC

11. Team Australia 40ºC

12. Team China 45ºC

13. Team Brazil 50ºC

14. Predict… In which country will the rate of reaction be the fastest? (assuming all other variables remain the same) Use the key ideas of particles and energy to explain your prediction.
