Pedal Boat STEM Kit – Buoyancy & Propulsion Science Kit for Kids Grades 3-5

Introduce students to buoyancy and propulsion with the Pedal Boat STEM Kit — a hands-on science experiment that brings engineering and core physics concepts together on the water. Students build and test a motorized boat, connecting a simple circuit to power the propellers while the hull design keeps it afloat. As they experiment with different designs and adjustments, learners observe how electrical energy drives motion and how buoyancy and propulsion work together in real-world watercraft.

A perfect ready-to-use lesson plan addition for elementary and middle school science classrooms, this kit makes force, motion, and energy transfer visual, exciting, and easy to teach.

Why Teachers Love This Kit:

• Learning Concepts: Buoyancy, propulsion, simple circuits, and basic hydrodynamics
• NGSS Standard: PS2 & PS3 – Motion, Stability, and Energy; supports Next Generation Science Standards for Energy and Motion
• Grade Level: Ideal for grades 3–5 science classrooms and after-school STEM programs
• Setup & Use: Ready-to-use, ideal for small groups or partner work

Perfect for energy and motion units, physics experiments, engineering design lessons, and STEM stations.

Battery not included.
