Investigate the properties of Slime, a trademarked toy material first marketed commercially in the 1970s. Your students will prepare this entertaining – yet educational – material using various natural and synthetic polymers and color it with various dyes. In addition, students will create Flexi-Putty, form it into a bouncing ball, and compare its properties to Slime. In the process, they’ll gain a better understanding of the chemistry behind these long-chain polymers and their application in a variety of products we use in everyday life.

Much like the AP Rocket, this kit offers a ball for a nose design that brings the rocket back to the ground without damaging it by increasing drag during the rocket’s descent.

Launching requires an AP Rocket Launcher II and air pump, sold separately. This is a quick and easy-to-build rocket; construction requires a ruler, scissors, T-pin, transparent tape, glue stick, and white glue.

Measures 12-1/2" L x 7/8" W x 7/8".

Even young students can learn some of the concepts of engineering used to create fascinating structures and do projects that help them apply the concepts. They will learn about:

  • Geodesic dome buildings and then build their own dome from mini marshmallows and toothpicks.
  • Roman arches and then assemble one from sugar cubes and glue.
  • Liquefaction, seismology, aquifers, corrosion, Newton's third law of motion, and much more!

The book features 25 hands-on projects and a glossary.

Kids invest a lot of time, heart, and hope in the construction of competitive CO2 dragsters. Protect that investment with our Competition Carrier, a hard-on-the-outside, cushiony-on-the-inside carrying case for one dragster. Constructed from durable ABS plastic, it features securely fastening snap closures and molded handles for convenient carrying.

Inside the case rests a thick foam cushion scored into multiple 1/4" x 1/4" x 1-1/2" sections. Each section can be removed to hollow out a space that fits the contours of almost any vehicle design. When safely nestled in its foam cushion, the dragster is covered with a foam pad, adding another layer of protection for a vehicle on its way to a competitive event.

Outside dimensions: 12" H (at the handle) x 14" L x 3-1/3" W. Inside dimensions: 8-1/2" H x 12-3/4" L x 2-3/4" W.

In Energy Resources: Use & Conservation, students learn that we can harvest the power of nature from a variety of sources all around us: the Sun, wind, and water; the atom; energy stored in fossil fuels; and the very heat of the planet itself!

They discover what life was like before people learned to harness electrical energy and how energy-rich fossil fuels like coal, oil, and natural gas helped fire the Industrial Revolution. They learn why these powerful energy resources are nonrenewable and in jeopardy of being used up as global energy consumption continues to rise.

Students are encouraged to play an active role in energy conservation and harness energy from the Sun by creating their own solar-powered oven. Part of the multivolume Energy in Action Video Series. Teacher’s guide included.
