How much weight can an aluminum foil Boat float?

Have you ever wondered why big ships float while small objects sink? This exciting activity helps you explore buoyancy by designing a boat made from aluminum foil and testing how much weight it can hold. As you begin, you’ll discover that floating is not just about size—it’s about shape and balance too.

You will create a foil boat and slowly add weight to see how much it can carry before sinking. By observing what happens, you’ll learn how spreading weight evenly helps objects float better. This hands-on exploration makes science concepts easy to understand and fun to test.

As you work through the activity, your science and math skills grow together. You’ll compare amounts, count added weight, and notice patterns in floating and sinking. Learning new science words helps you explain your observations clearly and confidently.
