STEM Science Station - Sink or Float

This STEM Science Station introduces children to the fascinating concept of buoyancy through engaging, hands-on experiments. Designed to inspire curiosity and scientific thinking, the Sink or Float kit lets children explore what floats and what sinks using simple materials and fun scenarios. From creating a floating starfish to sinking a miniature raft, students are empowered to experiment, investigate, and draw their own conclusions.

Educational Benefits:

• Promotes understanding of buoyancy and density through visual, tactile learning
• Develops problem-solving and critical thinking skills
• Supports independent and inquiry-based learning
• Builds scientific vocabulary and observational skills
• Encourages self-motivation and persistence

Classroom Ideas:

• Create a classroom water station where children can test and predict which objects sink or float
• Encourage group discussions around hypotheses and experiment outcomes
• Use extension activities to design buoyant objects using recycled materials
• Combine with storytelling (e.g. floating in the sea) to build cross-curricular links
• Use the kit for STEM rotations or science discovery corners
