Students examine the techniques that may be used to reduce carbon dioxide in the atmosphere. In this pollution lesson students simulate oceanic sequestration using chemistry.
Curated OER
Ecological Succession in Pond Water Cultures
Students collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.
Curated OER
Smelly Balloons
High schoolers investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the...
Curated OER
Mining Simulation
Eighth graders put their knowledge of rocks and minerals into perspective by seeing how minerals can be mined and the difficulties and costs of mining. They explore the environmental impacts of mining.
Curated OER
Acid Rain
Students perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Food Energy
Students compare the energy value of traditional foods eaten by indigenous people with those of modern commercial foods. They use a calorimeter to measure and calculate the amount of stored energy in various food types, and identify the...
Curated OER
Experiments in Nanotechnology: Ferrofluids
Students explore the world of nanotechnology by synthesizing ferrofluids in a series of chemical reactions. In small groups, they follow the procedure to create the ferrofluids using precise measuring techniques. They test the resulting...
Curated OER
Creating Coacervates
Students create and observe coacervates. In this origin of life lesson, students create coacervates by mixing carbohydrate and protein solutions. They observe the life-like qualities of the structures and discuss the origin of life.
Curated OER
Newton's First Law Crash!!
Students examine Newton's first law of motion and demonstrate how it applies to cars. In this motion lesson students complete an experiment and worksheet on speed and inertia.
Curated OER
A Comparison of Polymeric Liquids with Newtonian Liquids
Students concretely illustrate and define a macromolecule, observe the unique behavior of polymers and relate to their knowledge of molecules, and use the scientific process to determine the difference between Newtonian and non-Newtonian...
Curated OER
Enzymatic Action
Students observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other elements...
Curated OER
Measuring Calories in Food
Students measure the amount of calories in food. In this food energy instructional activity, students discuss what a calorie is, how our bodies use a calorie, and how many we need. Then, students use a calorimeter to calculate the amount...
Curated OER
Trapping CO2
Students investigate climate change and how the properties of carbon dioxide and methane play a part. In this climate activity students use a chemical reaction to trap CO2 and methane.
Curated OER
