Details

The Variable Inertia demonstrates an abstract concept in an easy-to-understand manner. It consists of two semi-clear plastic discs with the same mass and diameter. The discs are hollow inside with molded compartments. The 19mm steel balls can be placed inside the discs in a variety of configurations. Based on the location of the steel balls, the distribution of the mass will change, and the discs will become either "center heavy" or "rim heavy."


Ask your students, how does changing the position of the mass affect the speed at which the discs roll? The semi-transparent discs will allow your student to see where the mass has been placed inside the discs. After conducting the experiment, the student will be able to relate the position of the mass to the outcome of the experiment and answer the question.

This apparatus aims to help demonstrate rotational inertia and the effect that weight distribution has on it.

..I contacted Geyer via email. I had an email back within minutes!.. A back and forth via email sometimes takes days with other companies and customer service doesn’t happen like this very often. When it does, it’s much appreciated. Brett at Geyer was very polite and accommodating!

The customer service rep went as far as to reach out to the manufacturer of a product to answer my question, and then provided pictures. She really went above and beyond and answered the question thoroughly and gave me exactly the information I was looking for. This entire process was also extremely fast.

I called to ask how to submit a Tax Exempt Certificate for my library and spoke to a real person, no automation or asking me to press a number. He was friendly, helpful and got our Tax Exempt status established immediately.

...I don't think I've ever experienced that level of customer service before, and taking it into consideration along with the quality of their products, I would absolutely recommend Geyer to fellow teachers.
