A clever way to demonstrate the transfer between potential energy and kinetic energy
Create a model car consisting of a simple chassis and a straw-based axle system (simple machine) that produces minimal friction and allows the cars to roll with little energy input, making them ideal learning too..
Discover the rainbow of colors in white light!
White light is actually a combination of different colors. This easy-to-build spectroscope allows students to separate the incoming light into its component colors, forming a light spectrum (rainbow). Besides creating interesting color patterns it c..
Let a steel needle point the way!
The floating compass is a useful tool for detecting the magnetic fields of magnets and of the Earth. Make a simple compass with a magnetized needle demonstrates the properties of magnetic materials and shows that magnets have north and south poles. Using the floa..
Explore the fun of energy conversion
Enjoy the hands-on experience of building and using the Roller Racer, a modern variation of an old favorite. Explore the application of simple machines and energy conversion and investigate how changes in stored energy can affect performance.
Make a telescope like the one Galileo designed!
See how convex and concave lenses can be combined to magnify far-away objects.
Curriculum topics: Lights, Optics, Refraction, Astronomy
Kit includes: Idea Sheet, 10 plastic pipe caps, 10 convex lenses, 10 concave lenses, 10 cardboard tubes, an..
Explore renewable energy from the Sun
The Sun provides a daily source of free and non-polluting energy that can be collected and converted. Concentrate sunlight using a reflective collector and explore heating and “cooking” foods and other materials.
Curriculum topics: Solar Heating, Radiant E..
