We did an experiment to find out which material is the best to make earmuff and which material will keep our ears warm.
We worked as a team to wrap different materials around our beaker. Miss Garda then poured 50ml of boiling water into the beakers.
We then put the beakers outside for 5 minutes to see which material will keep the water warm.
After the 5 minutes were over, we measured the temperature of the water.
