By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...
