Designing Aluminum Foil Boats & Competition Lesson Plan

Designing Aluminum Foil Boats & Contest

Overview

In the aluminum foil boats challenge, elementary students learn about buoyancy by creating boats from aluminum foil. They experiment with different shapes to see which can hold the most weight before sinking. This fun activity teaches them about balance and how things float. The lesson ends with a competition, where students add weights to their boats and discover which designs work best.

Introduction

Subjects: • Science • Engineering • Math

Time: 60-90 minutes

Skills: • Teamwork • Problem-solving • Measurement • Engineering Design Process

• Understand the basic principles of buoyancy and density.
• Apply engineering concepts to design and build a boat that can hold the maximum weight without sinking.
• Evaluate the design and performance of their boats.

• Aluminum foil (sheets of approximately 12 inches by 12 inches)
• Weights for testing (e.g., pennies, marbles)
• Large container of water (e.g., plastic tub, sink)

Background

Boats float on water because their shape allows them to displace enough water to counteract their weight. Understanding buoyancy and density is crucial in designing boats that can hold weight without sinking.

Activity

• Introduce the concept of buoyancy and how boats float.
• Explain the challenge: Students will design and build a boat using only aluminum foil to hold the most weight without sinking.
• Show the class the objects that will be used as weights, other materials, and example boat designs

• Provide each team with one or two sheets of aluminum foil (or more).
• Students should start building their boats according to their designs.
• Encourage teamwork and problem-solving as they encounter challenges.

• Each team will place their boat in the water in the large container with water and gradually add weights until the boat sinks.
• Record the weight each boat holds and note the design features.

• Ask the students what they would like to change about their boat design and to brainstorm new features they could add
• Have them make a new version of the boat with the updated features and new design
• Retest this design and see if it can hold more weight than the first

This process of construction, testing, and redesign can occur more than once, the goal is for students to understand the fundamentals and that the process is not linear.

Extra

Tips for Students:

• Use the aluminum foil efficiently and strategically to ensure your boat is strong and buoyant.
• Think creatively about the design and aesthetic aspects of your boat.

Tips for Teachers:

• Have example designs of boats or pictures for students to look at
• The more rounds there are, the more materials students will need
• Other materials such as craft supplies can be added but this lesson mainly focuses on boats made solely from aluminum foil

• Integrate a math lesson by having students calculate the volume and surface area of their boats.
• Have students present their designs in front of the class
• Make other constraints, such as a character/figurine cannot get wet or that the boat can only be a certain length, etc.
