Levers: What Can Leverage Do For Me?
Students determine the identity of the three classes of levers while explaining how each works. They wait a video clip that shows uses for different types of levers and work as a class to write a KWL chart. Finally, they make a model fo...
Curated OER
Mobius Strips
Students discuss the scientific method and construct their own Mobius Strips. They examine their Mobius Strip, and write observations and a hypothesis on how many strips of paper they have when they cut the strip in half length-wise.
Curated OER
My Car Has Potential
Seventh graders investigate how changes in the mass or height of a ramp can affect the change in potential energy. They discuss the concepts of work and energy, then using the four question strategy, they design an experiment that...
Curated OER
Tobacco Smoking and Lung Cancer
Students explore tobacco smoking and the impact it has on society. In this health instructional activity students complete several experiments on smoking and lung cancer.
Curated OER
Fun With Food
Students participate in hands-on scientific experiments relying solely on household kitchen materials.

Building a Straw Power Tower
Learners build a tower out of straws. In this engineering lesson, students build a tower of straws that must be at least 58 cm tall. The goal is to be the group whose tower can support the most pennies. This lesson gives learners the...
Curated OER
Adventures in Electrical Engineering
Students explore electricity by conducting a series of experiments. In this physics lesson, students discover the relationship between current, voltage and resistance. They calculate voltage and power in a given system.
Curated OER
"The Yeast of Our Worries"
Students study yeasts or cellular respiration in this inquiry activity. They examine different types of bread to show which rise or do not. They measure the amount of carbon dioxide released by the yeasts when using different sweeteners.
Curated OER
