I've had this for a few years now. It is a great tool to help students visually understand force and motion.

This little kit provided good concrete examples of the Simple Machine concepts I'm exploring with my K students. I teach in a private school, and only have 5 students, so this little kit is great for them all to see and try. I will buy more of these kits for next year.

This force and motion lab is worth every cent of the cost! I bought two sets and was able to rotate my 20 students through tables. The materials are sturdy, reliable, and easy for children to manipulate. The teacher's packet was very informative and the lab copies were well put together. The only thing that would be nice is if we had the option of purchasing parts of the set separately as well.

It gives children a more hands on experience.
