Curated OER
More on Temperature and Solubility
Students discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.
Curated OER
Mixtures
Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.
