Based on a video visit to the Great Lakes Boat Building School, lessons include the phenomena of buoyancy and water displacement to help students understand why a boat floats. Activities also include learning about how boats have been made out of various materials — including wood — over the years and engineering a boat according to certain constraints to hold a certain amount of weight.
Lesson Objectives
- Know how the upward buoyant force that keeps a boat afloat is related to the amount of water displaced
- Understand the how the design of a boat helps it to stay afloat and hold weight
- Be able to design and build a model boat out of aluminum foil and tape to float in water and hold a specific amount of weight without sinking

Activity 1
This activity is a video discussion of a Great Lakes Now episode segment that discusses the design and building of wooden boats. During the video students need to jot down four things they took away from it.

Activity 2
This activity aims to provide students a better understanding of just how much weight boats can hold when they’re able to displace enough water because of the size of their design.
Activity 3
The purpose of this activity is for students to create a boat out of aluminum foil and tape that will hold the most cargo without sinking.
