Exciting Experiments

Bicarbonate of soda and vinegar

In Class 5 we have had 2 weeks learning about the properties of materials. We had some exciting investigations into solubility and reversible and non-reversible changes. We learnt that there are many different properties for different materials which help us to decide which material to use for which purpose.

In our experiments, we were able to see the salt particles join over time to create squares and cubes due to their atomic structure - very intriguing! We also saw the reaction when bicarbonate of soda is mixed with: water, lemon juice, or vinegar.
