• Homework set on Thursday 4th was due in
yesterday, Monday 8th
– Please hand this in by the end of this lesson, or
first thing tomorrow morning otherwise you will
receive a de-merit!
Check your notebooks!
Iron sulphide molecules
Let’s review our learning: show me boards
• How did we separate the Iron and Sulphur mixture?
• What do we call a material when two elements join
• What do we call the process when two elements chemically
• Could we separate the compound using a magnet?
• Are metals on the left or right of the Periodic Table?
• Are non-metals on the left or right of the Periodic Table?
• What are the only 2 liquid elements at room temperature?
• Are the gases on the far left or far right of the Periodic
• What is at the centre of an atom?
• What orbits the atom?
• Chemical reactions happen in our lives every
• Here are some examples:
Frying an egg
Lighting a match
More chemical reactions…
Petrol burning in a
Can you think of any more chemical reactions?
• Please copy this into your notebooks:
There are many, many different types of
chemical reactions. They all have some
things in common. We are going to
investigate some chemical reactions.
Time for an experiment!
• Burning Magnesium
– REMEMBER, do NOT look directly into the white
– Draw a labelled diagram of the experiment
– Note all of your observations
– What did Magnesium look like before it was
– What did it look like after?
Add this into your notebook after your report on
Magnesium + Oxygen Magnesium Oxide
When anything burns it takes in Oxygen from
Let’s review our results: show me boards
• What is the chemical symbol for Magnesium?
• What happened in the experiment?
• What did Magnesium look like before it was burned?
• What did it look like after it was burned?
• What new product was made?
• Was the new product a compound or a mixture?
• Can we separate the compound back to the elements?
• Where did the Oxygen come from to burn with the
• What is the chemical symbol for Oxygen?
• You will be performing more experiments on
chemical changes on Thursday…
• Using your traffic light colours – please let me
know if you have understood chemical
