A whole-group discussion kicks off a hands-on activity that challenges young engineers to build a sailboat using reusable materials. Participants gather recycled items to assemble their one-of-a-kind sailboat and test its ability to float and sail by making wind with their breath or fanning.

Instructional Ideas

• Locate a video or book of Curious George on a boat to hook learners at the start 
• Conduct the activity near Earth Day or part of a unit on recycling; emphasize the importance of reducing, reusing, and recycling 
• Go outside to keep your classroom from getting wet

Classroom Considerations

• Requires a variety of reusable materials; make a list of items needed and ask families to donate what they can
• Your age group may require extra assistance; invite volunteers to help build boats 

Pros

• Provides guiding questions and details how the activity connects to science and engineering
• Encourages creativity and imagination to build  a unique boat

Cons

• None
