Viscosity: The Fluid Lab
There's more to fluids than meet the eye—they include gases, liquids, and polymers, too! Scholars complete three hands-on activities exploring different properties of fluids. They explore viscosity by measuring the resistance, or...
Curated OER
Edible Transformations
Students differentiate the different phases of matter. For this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

Warming by Freezing
Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...
Curated OER
Solid Water
Students turn solid water (ice) into liquid water. In this solid and liquid water lesson plan, students use water, ice, cups, and heat in order to change water from one state to another. They draw their findings as well.
Curated OER
How Structure Can Affect Properties Through Phase Changes
Students discuss how changing the structure of atoms and molecules can change the properties of a substance. They brainstorm and review their own examples of phase change with the help of a phase change diagram. Students describe the...
