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.

Honestly Just What I Wanted
Review star icon Review star icon Review star icon Review star icon Review star icon Jul 31, 2019
The radiometer is a fond childhood memory, when I was younger- around 6 to 7- I would glance up from my bed when I was waking up to see and hear the radiometer spinning in the window frame. It was cool and mesmerizing to see it spin so fast, and simply due too the sun's light. Ever since I could not find the original one, so when I got this new one, it has taken it's place above my bed in the window frame, spinning, and spinning, and spinning away. It is honestly just what I wanted, as it is just what I remembered.

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.
