Core Skills Analysis
Science
- Exploring the principles of buoyancy and density by observing how the raft floats on water.
- Understanding basic material properties such as water resistance and weight distribution.
- Learning about the relationship between shape and stability in watercraft design.
Math
- Estimating and measuring dimensions of raft components to ensure balance and size appropriateness.
- Applying concepts of geometry to design a stable structure that can support weight.
- Using problem-solving skills to calculate how different materials affect the raft’s floatation.
Art and Design
- Engaging in creative construction by selecting and assembling materials for the raft.
- Developing spatial awareness and fine motor skills through hands-on building.
- Experimenting with aesthetic design while maintaining functionality.
Physical Education

Tips
To extend learning around raft building, encourage the student to experiment with different materials to observe how density and weight affect buoyancy. Introduce basic water safety concepts alongside the science of floating objects. Incorporate measurement activities by having them record dimensions and weights to calculate loads and predict outcomes. Combine art by designing visually appealing, yet functional rafts, and promote reflection on trial and error to foster critical thinking and perseverance.
