Pupils in 5th and 6th classes were busy experimenting during Science Week 2020. They explored a number of hypotheses including: Liquid density. Children predicted what liquids would be most dense, carried out an experiment using a variety of liquids and were fascinated with the result! Bubbles.Pupils tried different formulas of bubble mix, including a commercial one, to see which combination made the best bubbles. Using pipettes to blow the bubbles they discovered that bubbles are made up of a thin wall of soapy film that are filled with air. They were pleased to discover that adding glycerin to their mixture made bigger, l;onger lasting bubbles. Cleaning coins. Children experimented with vinegar, cola and some dull pennies to test the cleaning properties of both liquids. Rainbow marker coffee filter experiment. Pupils dotted a variety of colours on the centre of a coffee filter. They placed the filters in jars, added a small amount of water and watched the pigments separate!.
