Float Your Boat Challenge Write Up

Name: Mara                                                                                                BLK: D

CHALLENGE: Make a boat that can float in water and hold the most amount of      pennies.

PROBLEM: What materials can we use and how can we make a boat that will float in water?

HYPOTHESIS: If we use tinfoil as a base, and attach the straws on the perimeter and marshmallows on the corners of the bottom, the boat should be able to float.

IDEA FOR ORIGINAL DESIGN:  Insert image and write a description explaining your thinking/reasoning as to why you chose that particular design


 

 

 

 

 

 

 

We thought that the straws would add some support to the base, and the marshmallows would be able to resist water and therefore assist the boat in staying above the water once weight (pennies) were added. We also decided to add wax paper in the middle to hold a sort of curve for the pennies.

HOW MANY PENNIES DID YOUR BOAT HOLD?

35

WHAT WOULD YOU KEEP OR CHANGE ON YOUR BOAT DESIGN IF YOU WERE TO DO THIS AGAIN?  (saying nothing is not an option)

For the most part, our theory worked. The straws added support to the base and but it also allowed some water to seep through, next time, we should make sure that the ends of the straws are secure so they become more water resistant. The marshmallows also really helped the boat stay afloat and so did the wax paper, however it could only hold 35 pennies.
