• DIY: Baby Plasma Cutter

Pencil lead and some batteries make a small plasma cutter that is used to etch a pattern in aluminum foil.
In this simple but cool demo, you are able to observe how a high velocity ionized gas (plasma) conducts electricity across a small gap between the tip of the pencil lead (graphite) and a conductive solid [...]

• Newton's Eye Poke Experiment [W/Video]
Anna Spitz explains the physics of the eye, and proves how we actually do see an upside down world.
• Fun and engaging activities using the Energy Stick [W/Video]

Welcome to our March 2015 Issue of our CoolStuff Newsletter. This month, we are featuring a simple, safe and Cool device called an Energy Stick. Physics teacher James Lincoln demonstrates several experiments that help students understand the principles of electric current and light. James has authored many of our past CoolStuff Newsletters, and teachers have [...]

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.
