Hands-on buoyancy exploration for curious minds

This STEM set invites young learners to investigate how objects behave in water through a two-piece submarine and a floating raft, complemented by a spectrum of weights, rings, balls, and stars. With 32 pieces in total, it’s designed to spark tactile discovery and beginner physics thinking.

The kit includes ten detailed activity cards—covering over 20 hands-on activities—that illuminate core science ideas such as buoyancy, density, and settling behavior. An accompanying Activity Guide provides step-by-step prompts, adjustments for varying skill levels, and practical tips to keep investigations engaging. Educator-informed materials pair real science concepts with playful components to support approachable, goal-driven science play.

What you can explore

  • Buoyancy and density: compare how different shapes and weights influence float or sink behavior
  • Measurement and estimation: use simple tools to quantify outcomes and make comparisons
  • Prediction and observation: formulate hypotheses and document results during guided tests
  • Problem solving: design quick experiments to test ideas and refine approaches

Real-life use cases
