This afternoon, Year 6 have “combusted” iron wool and have found out that iron oxide is heavier than iron wool. This is due to
the oxidation process, which changed the iron wool to iron oxide (denser).
We did this by using electricity from a battery to add energy which created sparks; combusting iron wool looks very pretty.
“We tried different masses of iron wool and found out each time that the mass increased after combustion.” Jess Bullivant
“I enjoyed it because it wasn’t like any other experiment we’ve done before.” Poppy Bunn
