Science: Adding Solutes to Solvents
Students design experiments examining the effects of various solutes on water. They record results on graphs explaining any unexpected consequences of their experiments and determine if their hypotheses were correct.
Chemistry Collective
Brownian Motion
Explore particle motion between solute and solvents. An interactive simulation allows learners to observe the motion of solute particles as they interact with the solvent particles. It provides an option for including...

Freezing Point Depression: Why Don’t Oceans Freeze?
Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...
Curated OER
Mixtures
Students experiment with solutions. In this mixtures and solutions science instructional activity, students work in groups of three to perform an experiment. Students place a sugar cube in three glasses, and observe and record the...
Curated OER
Solution Shapes
Eighth graders examine different solutions. In this solution material lesson students complete a lab activity and several worksheets.

Visual Models of Solutions and Concentrations
Learners model solutions with beakers of colored glass or plastic spheres. In this solutions lesson, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions. They discuss...
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.
Curated OER
Study the Fizz
Young scholars experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson plan, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and...

Paper Chromatography
Students investigate the pigments in Magic Markers using chromatography. In this paper chromatography lesson plan, students use absorbent paper and mark the strip with a Magic Marker. They place the strip in a solvent and observe the...
Curated OER
Mixing in the Kitchen
Learners identify the different types of mixtures. They identify examples of solutions, suspensions, colloidal dispersions, and emulsions through a game and basic experiments.
Curated OER
Solubility
Fifth graders determine the difference between a soluble and an insoluble solution and how to increase solubility. They make a saturated solution using solvents at different temperatures.
