Pupils identify the various adaptations of reptiles and amphibians. After distinguishing between reptiles and amphibians, students discuss the ways in which their adaptations aid in their survival. They participate in a hands on...

What would you be if you were attached to another object by an inclined plane wrapped helically around an axis? In this fourth presentation that covers work and simple machines, young physicists look at Newtons and Joules as...

Students examine the parts of a lever system and their functions.  In this simple machines instructional activity students study the different classes of levers and what they are used for. 

Young scholars consider the relationship between form and flight and investigate the history of man made flight and how wing shape and flexibility affects the maneuverability of an aircraft.

Pupils research and experiment to discover the lifting power of helium gas.

High schoolers use the World Wide Web to access and use FoilSim. They also use the World Wide Web to access the NASA Glenn Web site for information relative to the factors involved with the flight of an airplane.

Fifth graders classify goods based on their value and decide what they would take with them if they were resettling to a new land. They write an essay defending their choices.

In this earthquake exploration worksheet, students complete 2 prior knowledge questions, then use "Levers Gizmo" to conduct several activities, completing short answer questions when finished.

In this levers worksheet, students follow directions to making levers with a ruler, weights, pennies, and more. Students then see how much force is needed when adding more weights.

Students view a video clip about suspension bridges. They discover what forces support this type of bridge. They build their own suspension bridge using classroom materials.

In this air pressure experiment instructional activity, students participate in an experiment with a ruler on a desk or table and a newspaper to prove that air is pressing on everything.
