This afternoon P3 conducted an experiment to find out what dissolves in water and what does not dissolve. Dissolving means that when it is mixed with water it disappears.

We got cups of hot water and lots of different things to test. We tested : sugar, coffee, sand, flour, tea, salt, bath salts, gray granules, chalk and bicarbonate of soda.

We predicted whether each item would dissolve or not dissolve by putting our thumbs up or down.

We also gave the water a stir when we put the item into the water. This helped some of them to dissolve.

This is a list of the things that did dissolve: bicarbonate of soda, sugar, salt, coffee, flour, bath salts and gravy.

We found out that the gravy granules only dissolved in boiling water.

This is a list of the things that did not dissolve: tea, sand and chalk.

We also found out that some of the things changed the colour of the water but did not dissolve, like tea.
