Is it soluble?

Form 5 have been investigating the solubility of various solids.

Form 5 learned about soluble and insoluble solids in Science this week.  They took a variety of substances and tried to make solutions with them by adding a spatula's worth to 5ml of water in a test tube.

After tapping the test tube to mix the two, the pupils then recorded whether the solid was soluble or insoluble.
