Curated OER
Calorimetry
High schoolers investigate calorimetry and set up equipment to measure calories. In this calorimetry lesson plan, students make a calorimeter and compare large amounts of heated water with small amounts to show the difference in...

What Floats Your Boat?
Students discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

Designing a Flotation Strategy for the Purification of Recycling
Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...
Curated OER
Towel Testing
Young scholars examine how to design and implement experiments. In this paper towel experiment lesson students test the strength of paper towels.
Curated OER
Testing Termites to Discover
Students design an experiment to discover how termites respond to their environment.
Curated OER
Mining for Natural Resources
Students discover that mining for nonrenewable natural resources has a dramatic effect on our environment. They gain an understanding of the processes involved in harvesting a natural resource and the impact it has on the earth.
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Physical/Chemical Properties of a Burning Candle
Students investigate the physical and chemical properties of a candle before and after it is lit. They conduct a burning candle experiment, and complete a KWL chart and worksheet, recording the results of the investigation.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Density Columns
Eighth graders create solutions with 5 different densities. In this chemistry instructional activity, 8th graders analyze the density of solutions stacked on top of each other. They document their data through graphing. This assignment...
Curated OER
Laboratory - Density of a Material
Middle schoolers conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.
Curated OER
Density of a Gas
Eighth graders investigate the mass, volume, and density of a gas by producing it in a chemical reaction. The entire Density of a Gas Lab and L section of the K W L chart be formatively assessed.
Curated OER
The Air Up There!
Students create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.
