Matter and Particles: Chemical
Changes

2. Homework
• Reviewing Homework 3 set by Mr Downs

3. Word Equations
Add this into your notebook after your report on
Experiment A (Burning Magnesium):
Magnesium + Oxygen  Magnesium Oxide
When anything burns it takes in Oxygen from
the air.

4. Conclusions
• Looking back at the three experiments we have
done, we can say that:
Chemical reactions have the following things in
common:
– They produce new substances
– They involve a change in temperature
– They involve a change in appearance

5. Let’s review our learning:
hands up please!
• Spot the mistake: when Magnesium reacts with
Oxygen, the mixture produced is called
Magnesium Oxide
• Name two changes that happened when you
added the two solutions together
• Chemical reactions have three things in common
– name them
• If we had weighed the Magnesium before and
after burning – which would have been heavier?
