Energy

What energy is, how it changes shape and why a marble needs a high start. Play first, then read how it works.

Game

Build a marble run from ramps and loops and watch an energy bar show height turning into speed. Five missions, from a simple slope to a grand finale.

Short reads with pictures. Many have a live experiment built in.

Energy is what makes things happen. Meet its forms, and see how it changes from one to another.

Energy never disappears. It just changes form. Watch a marble swap stored height for speed.

Why a roller coaster has to climb so high before it loops the loop, and the 2.7 rule that predicts it.

Hands-on activities for home, class or self-study.

A simple home or classroom marble run, three measurements to take, and questions that connect it to Marble Machine.
