Matter and Particles: Chemical Changes
Homework• Reviewing Homework 3 set by Mr Downs
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.
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
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?
What’s next?
