    What People Are Saying

    Demonstrates exactly what it should

  • This balance does a good job of demonstrating the relationship between weights and distances. Also, it was a good exercise to level the balance according to the instructions. I definitely recommend buying another knife clamp or two so that the effect of more than one weight on either end can be studied.

  • When I saw this product, I was truly concerned about the sturdiness and quality of the product. However, after a month of rigorous use, I find it to be a great addition to our Physical Science classroom. The students have enjoyed using it in all sorts of experiments. I would recommend this to anyone that is looking for an inexpensive, but sturdy balance.
    great balance for physics

  • This is a great demonstration balance for demonstrating forces and eqilibrium in physics. It wouldn't be my first choice as a simple balance for young kids, however. For physics, I use hanging masses and I've bought some additional knife lever edge clamps for this balance. I alss sometimes swap the 1/2 meterstick for a full meterstick.

      Demonstration Balance

      Use this inexpensive balance to show principles of mass, force and leverage. Move masses (not included) along the half-meter beam to equalize forces. You can also use it as a simple elementary balance by hanging plastic cups or bowls (not included) from the meterstick. Includes study guide with instructions and experiments.
