Easily illustrate the conversion of light energy into mechanical energy.

Description

Originally, designed by William Crooke in the 1860s, the radiometer still fascinates both young and old. Whenever light shines on the four diamond-shaped vanes the paddle wheel spins at up to 3,000 rpm. Great for illustrating the conversion of light energy into mechanical energy. Each vane is black on one side and white on the other. Because the black surface absorbs energy better than the white reflective side, the molecules of air move faster near the black surface. Molecules of heated air moving faster on one side of the vain than the other cause it to spin.

Great tool for teaching about energy, light, inverse square law, conservation of energy, energy transformation. Buy 2 or 3 because children drop them and they break.

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

4-PS3-1

Students can use Radiometers to make observations and measurements for evidence to construct an explanation relating the speed of an object to the energy of that object.

4-PS3-4

Students can use Radiometers in an investigation to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

MS-PS4-2

Students can use this tool to develop and use a model to describe how waves are reflected, absorbed, or transmitted through various materials.

HS-PS4-5

Students can use Radiometers to conduct investigations about technological devices that use the principles of wave behavior and wave interactions with matter to transmit and capture energy.

When light shines on the four diamond-shaped vanes, the paddle wheels spin. The opposite side of the vane is white because the black surface absorbs energy better than the white reflective side. The molecules of air move faster near the black surface. Great for illustrating the conversion of light energy into mechanical energy.
