We made crystals in class yesterday. To do this experiment you need a jar, a jug, a pencil, boiling water, some thread, a paper clip and salt. First we put some boiling water into a jug. We then poured salt into the jug and stirred it to dissolve the salt. You keep putting in salt until it stops dissolving. Then you leave the water to cool. When it is cool, pour the water and salt mixture into a jar. Next, tie a paper clip to a piece of thread. Tie the other end to a pencil and drop it into the jar. It shouldn’t touch the bottom or the side of the jar. Leave it somewhere to cool fully overnight. Crystals will appear on the thread. It was good fun doing this experiment.
