About the course

On a hot summer day, when you leave ice out, it melts into liquid. And if it’s hot enough, it evaporates into water vapor. Explore how matter changes from one state to another, and visualize how temperature can measure kinetic energy.

Let's get molecular with matter! Engage in experiments exploring the four states of matter, kinetic energy, and water cycles.
