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 [...]

Show Them the Speed of Light, Using a Chocolate Bar!
If you have the typical classroom, your students will be a little extra distracted this February 14th for Valentine’s Day. We found a fun way to capture their attention on this sweetie-filled holiday and still teach a little physics in the process. In particular, you can [...]

Students investigate properties of mechanical waves using a "slinky" spring: wavelength, speed, reflection, standing waves, interference.
Good for grade levels 5 through 8
Super Springy, Stopwatch, String, Masking Tape, Helical Spring
Acknowledgements: Thank you to Dwight "Buzz" Putnam for his assistance in developing this lab. Buzz is a 25 year veteran physics teacher at Whitesboro High School, New [...]
Posted on January1,2011 by Arbor ScientificIn this activity, students will investigate the splitting of a light beam that occurs when the beam passes through a diffraction grating. You will determine the role of wavelength and line spacing in the resulting pattern. When light passes through a pair of thin slits, an interference pattern reveals the wave nature of light. A diffraction grating is a film with thousands of slits. Light waves passing through a diffraction grating also produce an interference pattern. The geometry of the pattern depends on the spacing of the slits and the wavelength of the light.
