The total amount of energy in the system remains the same. This energy does not disappear, however-it is converted into other forms like heat and sound. The marble also loses a small amount of energy due to friction, or when it collides with the walls of the track. Its potential energy is converted to kinetic energy, the energy of motion. When you release the marble, gravity starts to pull it down the track. Potential energy is the energy an object stores due to its height off the ground and its mass. It can be hidden away which is music to this mom's ears.What happens as your marble races down your marble run? First, when you raise your marble off the ground, you give it gravitational potential energy*. This set has ONE piece with a button battery, but it is screwed inside a light. I have a small child so that was not an option. It had button batteries on each marble piece. The more I looked at it the more I decided I did not want it. I was going to give it to my kids for Christmas, but then they found it in the car where it was supposed to be hiding. I actually bought something very similar during Target's summer toy clearance. The toy that I am going to review today is the National Geographic Glow In the Dark Marble Run.
We are all about STEM here especially with my kids home 3 days from school a week for now. They asked me if I wanted to review a couple other toys other and I jumped at the chance. I found National Geographic when they were promoting their Blockaroo toys, also a great toy. I have searched out the best toy companies when I attended the 2020 New York Toy Fair and have been super lucky to review some toys from them this year. Every day I consider myself lucky when a toy box arrives.
