Mystery Powders
Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.
Curated OER
Constancy and Change
Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.
Curated OER
How a Liquid Changes to a Gas
Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...
Curated OER
Solid, Liquid or Gas?
Students explore solid, liquids, and gases. In this science lesson plan, students distinguish similarities and differences of matter and recognize that different states of matter may appear in one substance.
Curated OER
Performing Well Under Pressure
Students study the physical properties of minerals and illustrate their functions. In this mineral lesson students construct models of some minerals.
