Curated OER
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.
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
Students 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
Permeability of Earth Materials
Students observe and classify the permeability of a variety of materials.
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
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
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
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.
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
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
Towel Testing
Students examine how to design and implement experiments. In this paper towel experiment activity students test the strength of paper towels.
Curated OER
Soil Comparison and Analysis
Students perform tests on different soil samples. In this earth science lesson, students classify the soil into groups according to test results. They write a lab report following a certain criteria.

Teach Engineering: Density Column Lab Part 1
In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...
TeachEngineering
Teach Engineering: Density Column Lab Part 2
Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as...
