Kinetic Theory Model STEM Lab
Product Code : SCL-MH-12540
Quick Answer: The Kinetic Theory Model simulates gas molecules with steel and polymer balls agitated by a variable-speed vibrating base inside a clear acrylic cylinder. A floating graduated piston shows how volume and pressure respond to changes in “temperature”.

About This Product
At low speed the balls jiggle close together like a cool gas; at high speed they fly about the whole chamber. Holding the speed steady and pushing the piston down makes collisions with it more frequent, illustrating Boyle’s law, while letting the piston float and raising the speed lifts it, illustrating Charles’s law. Mixing light and heavy balls shows how molecules of different mass behave at the same energy.
Frequently Asked Questions
How is temperature represented in the Kinetic Theory Model?
By the speed of the vibrating base. Turning the speed knob up gives the balls more kinetic energy, like heating a gas.
How is Boyle’s law shown?
Keep the vibration speed constant and push the floating piston down; the smaller volume brings more frequent collisions on the piston, representing higher pressure.
