A grade 8 science experiment involving kinetic molecular theory?

Answer 1

Hmm, experiment's concerning Kinetic Molecular Theory. Simple experiment's off the top of my head are a ballon, with a hot and cold water bath, observe the effects of temperature on volume. Another temperature vs. volume experiment (more like demonstration, if this is for the 8th grade) is: placing approximately 5mL of water in a empty soda can, heat on a hot plate until steam starts to form, using tongs place the can upside down in a pan of cold water, the gas inside the can cools and contracts thus decreasing the internal persure and making a satisfying implosion, you can experiment with heating times to get the coolest implosion (if the can stops steaming take off the hot plate, there is no more water!). Those are the two that I can think up right now. I'll ask my AP chem teacher to help.

Answer 2

An experiment could involve demonstrating the concept of diffusion using food coloring in water. Students can observe how the food coloring molecules spread out in the water due to random motion, in line with the kinetic molecular theory which states that all matter is made up of particles in constant motion. This experiment could help students visually understand how particles move and interact in different states of matter.
