While this is geared for the Intermediate/Middle school level, I think both older and younger children can learn a lot from it. My children are on the younger side (3, 5 and 11). My 11 year-old helped daddy build while the 5 year-old watched. All three children enjoy watching the clay "fly" through the house! The 5 year-old asked to see which one made the clay go farther (she wanted them to "race"). We didn't use many of the experiments in the book because they are written above the level of my children but we are saving it and the machines for when they are ready! We did, however, lead the children in discussions that were related to the experiments in the book and did some modified (age-approipriate) experiments.
Other thoughts:
~The kids LOVE it! They love watching the clay "fly" and seeing how far it will go. The also enjoyed seeing how it was built.
~Daddy and Unicorn said the directions were easy to read and follow. It only took about an hour to build each one. (That is start to finish including drying time).
~I loved that it was a fun and easy way to bring Daddy into a homeschooling project! I was able to take pictures (see below)!
