MODULE 6. HANDS ON ACTIVITIES: WATER EXPERIMENTS
In this section we propose a number of hands-on activities in chemistry to increase students’ knowledge of
•

Add some food colouring and about a teaspoonful of salt to the water in the bowl.

•

Take all the equipment out to a sunny, level place.

•

Place the glass or cup in the middle of the bowl making sure no water splashes into it. •

Cover the bowl loosely with cling film, sealing the film to the rim of the bowl.

•

Place the stone in the middle of the film above the cup.

•

Leave the still for at least an hour (the longer the better) and then check that there is some water in the cup.

•

Take the still back indoors, remove the cling film and take out the cup without splashing any water into or out of the cup.

•

Measure the amount of water in the cup.

•

Observe the colour of the water in the cup and test it for salt.

•

Calculate the percentage of the water that was purified:
