This kit is truly packed with parts, including a beautiful, precision, brass colored balance scale to measure mass, a hover puck, a jet car that really zooms, the components to make your own spring meter, an accurate to 1/100 of a second stop watch to clock speed, velocity and acceleration and the tubes, stoppers and inflation needle to launch both water rockets and baking soda rockets. Each project has been lovingly crafted through years of testing and feedback with children into joyous, age appropriate fun. 

The systematic coverage of the physics behind the play flows smoothly and whimsically into a deeply intuitive grasp of Newton's fundamental laws of motion. This title is such a party and so visual, that even very young children simply love it.  Like many of our other titles developed for this age, there is so much here that a surprising percentage of the children in our enrichment classes and summer camps have communicated that they partied with the materials when they were very young and then revisited the book and projects a second and even a third time as they grew older and understood it with an ever deepening comprehension. Like other classic titles you learn more each time you visit it.

Perhaps more than any of our other titles, we have heard over-and-over from older siblings and envious older students in middle school, in high school and even in college comment, "I am just learning that now. Why didn't I have this when I was little?"
