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.
Curated OER
What's the Matter? (Experiments)
Students observe a scientific discrepant event, and are then challenged to create experiments to solve the dilemma.
Curated OER
Let's Take a Rock Apart
Students take a crushed rock and sort the remains of the rock minerals into different categories based on the different properties. In this sorting lesson plan, students learn what makes up a rock and how to sort something into categories.

Where's the Evidence?
Eighth graders observe evidence of chemical reactions. In this chemical reactions instructional activity students study chemical processes and complete a lab activity.
Curated OER
Is Dilution the Solution to Pollution?
Students explore the different types of pollution. they conduct experiments using dye mixed with tap water to measure the levels of dilution. They discuss at what point the dye (pollution) would be diluted enough to be safe to drink.
