The Composition of Potassium Chlorate
The third lesson plan in a series of 11 begins by using thermal decomposition of potassium chlorate to determine the mass percent of oxygen. Then a second activity allows scholars to demonstrate that the resulting residue is from a...
Curated OER
What's Happening Below The Surface?
Students determine the soil composition of soil layers in their area. They collect soil samples, calculate the percentage soil water content, analyze data, and evaluate each site for future tree growth.

A Crust Full of Rocks
In this rock worksheet, pupils answer seven short answer questions about the composition of the earth's crust. Questions refer to metamorphic, igneous, and sedimentary rocks.
Curated OER
The Atmosphere
Learners calculate the percentage of oxygen in the atmosphere. They create a semi-scale drawing of the atmosphere.
