Groundwater Movement
Students study groundwater movement beneath the surface of the Earth. In this agriculture lesson, students experiment with how water moves through rock materials such as sand, gravel, and clay.
Curated OER
Breaking it Down
High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...
Curated OER
Osmosis
High schoolers investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into...
Discovery Education
School of Rock
Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

Solvent Snapshot
Discover the properties and purpose of chemical solvents. Continuing with the theme of shampoo ingredients, the 10th lesson of this 24-part series investigates the choice of solvents in shampoos. Through their exploration, they learn how...
Biology Junction
Water, Solutions, pH, and Buffers
What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Spin the Saltine!
Students investigate chemical energy. In this physical science lesson, students blow on saltine crackers to demonstrate how chemical energy in food can be converted to motion. Students compare the saltine cracker experiment to how...
Curated OER
Soak it up
Students complete a hands on activity using hard boiled eggs, food coloring, tape, cups, water, and a knife to show how permeability affects animals. In this permeability lesson plan, students complete this activity and learn how...
Concord Consortium
Energy of Bond Formation
Show your chemistry class that there's much more to covalent bonding than sharing electrons! Pupils manipulate atoms of hydrogen, oxygen, and carbon to observe the energy of bond formation using a well-rounded interactive. The resource...
Curated OER
Weathering
Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson plan, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to...

Science:Effects of Weathering
Seventh graders take an outdoor observation walk around the campus and take soil samples. Working in groups , they conduct experiments with rocks and soil that demonstrate the effects of different types of erosion.
Nuffield Foundation
Observing Earthworm Locomotion
One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...
