Doing a bit of work on density with 7C and so they did a quick bit of revision of some Year 6 work, density in solids.
First regular objects
Get the ruler out
then find the mass
Then they did irregular objects
using water and measuring cylinders with Archimedes Principle to find the volume
Some objects floated so that problem had to be overcome.
After that they found the density of water and then air. Tomorrow carbondioxide!
