We used this in groups of 5 in my 4th grade class. Each student was able to create a machine with help from the group. After creating the machine, they used the activity cards- reading and answering the questions for that machine. I went around and checked their answers and then they moved on to the next machine. This is a great tool for understanding simple machines, student led learning, and cooperative learning. I would also recommend the activity cards that go with it.
So far this has been a great product. We use this product several times a day as part of our homeschool, for teeth brushing, reading, chores and so much more. It's easy to set and I love the versatility of the timing options. Not that we would need to set a timer for 1-2 seconds, but if we did it will definitely to that no problem at all.
Purchased this for my kiddo and she loves it, especially since she can remove the top and climb in there. I store some of her toys in there; well built - solid, no splinters. It is a great toy for the little ones.
