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
Density Discoveries
Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.
Curated OER
Science Lesson Plans
Students conduct a variety of exploration activities on various science topics. In this science lesson outline, students design a cell encapsulation to hold a specific type of medicine. They give examples of physical and chemical...
Curated OER
Testing Density of Various Soap Products
Students have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.
Curated OER
Project Geode
Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
Curated OER
Aluminum Foil Boats
Pupils design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.
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...

Selecting Soil Organisms in Compost
Pupils 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 in...
Curated OER
Permeability of Earth Materials
Students observe and classify the permeability of a variety of materials.
Curated OER
How Dense Are You?
Students examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.
Curated OER
Testing Termites to Discover
Students design an experiment to discover how termites respond to their environment.
Curated OER
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
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.
