Investigate all aspects of velocity, kinetic and potential energy, work, and more with the models built from the roller coaster set. Eleven different classic coaster designs are capable of construction with the 2,039 pieces in this set. Compatible with datalogging sensors from Vernier, Pasco, and Texas Instruments, your students can measure and record results from their built models. All pieces come packaged in three large, silver storage trays with moveable dividers. Includes teacher’s guide aligned to NSES standards and CD-ROM of color-coded building instructions.

Students will love this simple but impressive demonstration. The “apparatus” consists of a pair of heavy (454g) hardened, chrome plated steel balls. The demonstrator holds one ball in each hand a few inches apart, and an assistant holds a piece of paper between the balls. The demonstrator strikes the balls sharply together. Immediately, a hole with charred edges appears in the paper, with a smell of burning! Since the hardened balls are not deformed on impact, most of the kinetic energy of the collision is converted to heat (and sound). The heat is sufficient to burn a hole through the paper.

Simply connect appliances to the Kill A WattTM, and it will assess how efficient they are. The large LCD display shows consumption by the Kilowatt-hour, just like the power company, and also displays voltage (V), line current (Hz), current (I) and more. Students can calculate the cost to run any device with this inexpensive and easy-to-use meter.
