  • Behind the Scenes with Light & Color: 10 Great Demos
    Did you know the yellow you see on your smart phone doesn't actually contain the color yellow? It's true! Watch this revealing video to see this - AND 9 more great demos that show there's more to studying light and color than meets the eye.
  • Measuring the Acceleration with the g Ball
    Galileo claimed that all objects fall toward Earth with the same acceleration. Modern measurements indicate that this acceleration is about 9.8m/s2.  Using the G-Ball by Arbor Scientific, you can measure this value and compare the acceleration of other objects with different masses and in different states of motion.
  • Turn Your Mobile Phone into a Mobile Microscope [W/Video]
    Can the new Cell Phone Magnifier unlock why Mint Mentos's are better than Fruit Mentos for making soda explode? Check out this inexpensive option for those times when high-powered microscopes aren't necessary.

The Blue-Violet Laser

The wavelength you've been missing!

Take a look at the new blue-violet Laser, which produces wavelengths at 405 nm. Sure, it is a different color and that is always cool, but why use this over any other Laser?

Labs & Activities

  • Momentum - Tailgated by a Dart
    In this lab, students will learn to estimate the speed of an object by applying conservation of momentum to an inelastic collision. Energy is not lost its transferred from one object to another. Students will fire a dart into the back of the free rolling car and measure the distance of the car, calculate the speed of the dart and car, and measure the mass of the car and dart.
  • Density Rods
    The Density Rod Set consists of two rods. The aluminum rod sinks in warm water and floats in cool. This is because cool water is more dense than warm, and the aluminum rod is made to be between those two densities. The PVC rod does the reverse – floats in warm water and sinks in cool. This time, the rod changes more than the water, becoming more dense when it is cool.
  • Quantum Lab (Inquiry)
    Something that is quantized exists in multiples of a set quantity. Examples are charge [1.6 x 10-19C] or quantum energies of photons. Planck and Einstein predicted that light existed as discrete bundles called photons. Since they could not see a unit of photon energy, this lab constructs a model of how quanta was derived and visualized by scientists. In this INQUIRY lab, students will develop their own method for finding the pennies' mass.
