Foam ball has a battery-powered buzzer inside. Start the buzzer and play catch. Throw it fast enough, and students can hear the frequency shift!

Doppler Ball-waste of money

Comments about Arbor Scientific Doppler Ball:

I was so psyched about this until I used in with my classes. The motor disconnected from the wires by my second class period. Since I had two, I was frantically trying to find a way to repair it. No such luck. The alarm is also a piece of junk. It wouldn't not keep the same pitch so it was impossible to observe the change when tossed. I ended up making up a new alarm with my own materials that were highly successful in my last class period. Then I realized how cheaply the thing was made. I could have bought the foam ball, cut a slit, and added an alarm system with a SWITCH. What a rip off!

ArborScientific Response: Please contact customer service for a replacement. A modification has been made to the wires to keep them in place better.

Comments about Arbor Scientific Doppler Ball:

Used to demonstrate doppler effect... the one addition that I added was to put the ball on the end of a string with a net holding the ball....swing the ball horizontally above your head... the effect becomes very evident.

Comments about Arbor Scientific Doppler Ball:

Doppler ball has variable tone (defective) and takes some fiddling to make constant. Tone is kind of quiet and the battery unit must be placed very near the edge of the opening to be heard effectively.

ArborScientific Response: This is not a normal experience. Please contact us at mail@arborsci.com for a replacement.

Comments about Arbor Scientific Doppler Ball:

I used this for my physical science lab. I lined them up and threw the ball past their heads. They got the concept! It was nice that the ball is soft as my aim wasn't always great.

I love this simple demonstration!

I just have students throw it to each other before and after I've explained the Doppler effect. It really helps their understanding.

Doppler Ball - very simple and useful

By Nikki

from Torrance, CA on 10/26/2007

Pros:

Easy and effective, Good Value, High Quality

Best Uses:

Student interactive, Teacher demo

Bottom Line:

Yes, I would recommend this to a friend

Comments about Arbor Scientific Doppler Ball:

The ideas for use were helpful. I demo'd it for my students and then let them toss it around. The demo was more effective for teaching the Doppler effect than the tossing - they were too interested in catch and throw to pay close attention to the sound change.

it will be better if having a switch

By Yalan

from Rocklin, CA on 5/14/2007

Comments about Arbor Scientific Doppler Ball:

it is useful for classroom demo, but should build the set (battery, buzzer, and switch) inside of the ball.

ArborScientific Response: The buzzer assembly resides inside a slit in the foam ball, and is easily removable for battery changes, but the foam ball securely holds it in place when thrown.
