Our primary 4A students had a great time in the laboratory.
First we were dealing with the density of different materials in our daily lives.
They had to guess if some things would float or sink in water before the experiments
Then they had to identify homogeneous and heterogeneous mixtures.
We used everyday objects such as water, oil, vinegar, milk, sugar, a plastic comb, two balls of pasticine, two pebbles, some sand, etc
