What Are Solutions?
In this solutions worksheet, students brainstorm different types of solutions and an example of each type of solution. This worksheet is a graphic organizer.
Curated OER
Mixtures
Young scholars 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.
Curated OER
What is in the Water?
In this mixtures worksheet, learners read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.
