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?
