Water Wizardry

We experimented as to whether or not substances would dissolve in water. We took 6 jars per group and half filled each with water. We labelled each jar and added a different substance (salt, sugar, flour, pepper, rice or sand) to each. We observed what happened, then we mixed and observed further. Sugar and salt dissolves in water. The flour and pepper mixed a little with the water. The rice and sand did not dissolve or mix. We repeated the experiment with hot water to see if there was any difference. We found that sugar and salt dissolved faster in hot water. It made no change to the other substances. We recorded our experiment in our Science copies.
