If someone yelled for eight years and eight months, they could produce enough energy to heat one cup of coffee. A lesson on energy encourages scholars to research 10 different energy sources in groups before playing a game. Twenty...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Using a teacher-built wind tunnel constructed from a paper concrete tube form, a fan, and a balance, individuals determine the amount of drag their rocket design will experience in flight. Pupils make modifications to increase the...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

Middle schoolers design and build their own car. In this physics lesson, students collect data to determine the speed of the car. They plot the data on the graph analyze the relationship between variables.

Students experiment with buoyancy as a force. In this buoyancy lesson, students access an assigned website to examine the sailing vessels that came to the New World. They work as teams to build boats out of aluminum foil to see which...

Learners write a sketch of an artist or athlete that has pushed the limits on gravity. They explore concepts of rhythm, balance and friction. They examine how engineers design sports equipment.
