Float a Boat!

Webb and Bill explore the concept of floating and sinking by building and testing canoes made from aluminum foil. They explain how displacement allows objects to float and demonstrate this by filling their canoes with marbles until they sink. The video concludes with a discussion on why the canoes sank, emphasizing the relationship between the weight of the displaced water and the object.

What is the principle that explains why objects float?

• Density

• Gravity

• Displacement

• Buoyancy

What materials did the hosts use to make their canoes?

• Paper and string

• Aluminum foil and tape

• Plastic and glue

• Wood and nails

Why is it important to have the ends of the canoe taller than the middle?

• To ensure it floats better

• To use less material

• To make it look like a real canoe

• To make it easier to hold

What did the hosts use to test how much the canoes could hold?

• Rocks

• Marbles

• Sand

• Water

What happens when the weight of the canoe exceeds the water it can displace?

• It floats higher

• It stays the same

• It sinks

• It moves faster
