This activity set includes 10 different manipulatives, 1 tugboat, 1 sorting bowl and an Activity Guide. An ideal early STEM resource, this set assists in the observation of floating or sinking concepts such as weight, volume, density, buoyancy and more. Children can predict an object's ability to float or sink by observing its physical attributes. Children can also practice classifying and sorting the brightly colored manipulatives into "floaters" or "sinkers". The Activity Guide provides extended play options and teaching ideas. Children can start with beginner STEM lessons and move to advanced concepts. Includes: 1 x sorting bowl, 1 x tugboat, 8 wooden geo solids, 10 x 1" plastic geo solids, 8 x 8cm geo volume solids, 4 x 2cm foam cubes, 4 x 2cm plastic cubes, 6 x transparent pattern blocks in 6 shapes, 12 x plastic stacking weights, 12 x stacking counters, 6 x small pet counters, 6 x big pet counters and an Activity Guide. For ages 3+. Water tank not included.
