Testing materials in Science

Back from the holiday rested and raring to go!
The inquisitive minds of Year 5 have been experimenting with the properties of materials, our science topic for this term.  We have made a start by reminding ourselves of what we already know, such as magnetism, sink or float and Moh's test for the hardness of rocks.  We also built a simple conductivity tester to test whether materials are conductors or insulators.
