Designed boats using aluminium foil and predicted how many paper clips it would hold. Discussed density, surface area and surface tension. Redesigned the boats to improve the bouyancy.

Science

• The student learned about density, as they had to consider the amount of aluminum foil used in relation to the volume of water displaced by the boat.
• They also learned about surface area as they designed the shape of the boat, considering how it would affect its ability to hold paper clips.
• By predicting and experimenting with the number of paper clips the boat could hold, the student gained an understanding of surface tension and buoyancy.
• Redesigning the boats prompted the student to think critically about how to improve buoyancy, incorporating elements of design, engineering, and problem-solving.

For continued development related to this activity, encourage the students to explore further experiments with different materials to create boats, such as using clay, plasticine, or even crafting materials like popsicle sticks. This will allow them to continue exploring concepts of buoyancy and surface tension in a creative and hands-on way.
