Year 5 continued looking at properties of materials as part of their Science topic today in Forest School.

We talked about the difference between reversible and irreversible changes, and then carried out our own experiments, exploring the different indicators of chemical changes.

We investigated the effects of mixing bicarbonate of soda with vinegar, observing the gas it produced, the sulphur produced between raw and cooked eggs, the sounds effects of popping candy and the differences between fresh milk and sour milk!
