Science in Emma’s 3rd Class

This week we did science with Kathy, Gracie’s mum. We are very grateful that Kathy came in to share her expertise, parents are always welcome in our class.

Before we started our experiment, we put on our safety glasses and gloves which Kathy brought in for us. She kindly let us keep them.

We dipped a swab into different liquids and tested it on litmus paper. We tested it with bleach, lime juice, Gaviscon and water to test the pH levels. We observed that bleach was navy and base or alkaline, Gaviscon was dark green showing that it was on the way to becoming base, lime juice was orange which shows that it’s acid, water was green which showed that it was neutral.

It was lots of fun!
