Creates mesmerizing standing waves with a simple string.

Description

Create mesmerizing standing waves with a simple string by adjusting the speed of the machine's two motors and the distance between them. In the dark, the light from red, green, and blue LEDs allows a full spectrum of brilliant color. The variations in standing waves are limitless! Great for teaching about nodes, antinodes, and wavelength. 20" x 9.5". Uses 4 AA batteries (not included).

Not sure what this teaches but ive loved them for a decade. It does not come with a 6.1 volt adapter!!

I LOVE this machine. I buy these 2 at a time and have given them to my friends who appreciate them and now THEY love it too. The one thing Ive found difficult is finding the 6 volt one amp dc adapter not inckuded which i found at best buy for $22.

Fascinating teaching tool

Yes. It teaches about waves frequency and synchronisation while being pleasant to watch. A 6 volt 1 amp dc adspter is not included and is hard to find.

Very fun

This is a great example to explain standing waves. Will use at end of semester. Had a chance to show to former students and they were sad I didn't go have it last year. I would like it better if I could change the speed more.

I wanted to use this to teach waves to students, but had a hard time getting reliable waves. Sometimes I could get it to hold a wave nicely, other times not at all. Too much fiddling about to do in front of a class. Very frustrating. A toy.

Amazing!

This machine is an excellent device to teach standing waves. It is easy to set up and control and produces several different patterns of standing waves in a rotating string, which is about 20 inches long. The built-in LED multi-color illumination enhances its performance when is presented in a dark. Despite moving parts is safe to operate and even touch.

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

1-PS4-3

Students can use the 3D Standing Wave Machine to plan and conduct an investigation to determine the effect of placing objects made with different materials into the path of a beam of light.

4-PS4-1

Students can use the 3D Standing Wave Machine to model waves and to describe wave patterns in terms of amplitude, wavelength, and the fact that waves can cause objects to move.

MS-PS4-1

Students can use the 3D Standing Wave Machine in an investigation that uses mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to its energy.

MS-PS4-3

Students can use the 3D Standing Wave Machine in an investigation to integrate qualitative and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information.

HS-PS4-1

Students can use the 3D Standing Wave Machine in an investigation that uses mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of the waves traveling in various media.

Suggested Science Idea(s)

1-PS4-3

Direct a strong beam of light at the 3D Standing Wave Machine. Students can explore how that light travels through the wave while it is in motion.

4-PS4-1
MS-PS4-1
MS-PS4-2
HS-PS4-1

Students can use the 3D Standing Wave Machine in many hands-on investigations looking at waves. Allow students to visualize and manipulate the 3D Wave Machine to better understand waves.
