The Chemistry of Refining Crude Oil
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

Nailing Rust
When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Chemistry Lab-Molar Volume of Gas
Learners determine the molar volume of hydrogen gas. In this molar volume lesson plan, students find the molar volume of hydrogen produced in a reaction between magnesium and hydrochloric acid. They use a eudiometer to measure the volume...

From Polymers to Bioplastics: Looking Toward Finding Renewable Resources
Students investigate the properties of polymers. For this chemistry lesson, students explain the importance of energy sources. They produce a bioplastic from the lab and evaluate its structural integrity.

Seltzer Breath
Young scholars investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.
Curated OER
Periodic Behavior of Oxides
Students investigate the properties of oxides and observe their periodic trends. For this behavior of oxides lesson plan, students experiment with metallic oxides and non-metallic oxides to determine if they are acid, basic or amphoteric...

Osmosis Investigation
High schoolers investigate osmosis as they determine how carrot cells respond to two different environments. They conduct the experiment, record the data, and answer discussion questions.
