These items are well made and I never have to worry about them breaking! My preschool child care kiddos love the visual with a clear tub and are challenged with the activity cards. They ask a lot of inquiring questions and love to see what happens when they add more weight to the boats, etc.

I bought this when it was a monthly special at 50% off or I would have passed. My kids do love playing with it. I suggest that you also laminate the activity cards since water is obviously involved.

there is so much you can do with this set! we did guessing charts, and used it for sensory and science centers in preschool. The kids even brought in their own items and we could guess if they would sink or float.

I like the activities in this station. I do think it is over priced, a container for the water is not included.

I would have given this kit 4 stars if it weren't so expensive. I really like all the suggested activities as a way to extend the study of buoyancy beyond simple float or sink observations, but it does seem a little over-priced.
