Gather Your Materials
Your Engineering Challenge:
Design a boat that can hold as many pennies as possible without sinking!
Create your Cargo Boat Prototype
1) Cut one 6 inch by 6 inch square out of aluminum foil.
2) ONLY using the aluminum foil, design a boat that you think will hold a lot of cargo (pennies). Do this by folding and molding the foil.
Upload a drawing or photo of your cargo boat OR answer the question below.
Describe your design - what does it look like? Why did you design it that way?
Predict how many pennies you think it will hold:
Test Your Prototype
1) Add pennies to your boat, one at a time.
2) Repeat this until your boat starts to sink!
How many pennies did your boat hold?
What were some difficulties you had with this design?
Your new challenge is to design a new cargo boat that can hold EVEN MORE pennies! You get to decide on the size, shape, and folds of the aluminum foil. Continue re-designing until you have a success. Think about WHY your new design works better.
Upload a drawing or photo of your re-designed cargo boat OR answer the question below.
What did you do differently this time? Why?
How many pennies did your re-designed boat hold?
Communicate Your Results
Why do you think large boats can float on water, even though they are really heavy carrying a lot of cargo?
What advice would you give engineers designing a boat?
