HYPOTHESIS(仮説):  (Use an “If…then…”statement)

If bottom part of the boat is bigger, then the buoyancy of the boast will increase and it will hold more pennies.If I can reinforce for floating, then the buoyancy of the boast will increase and it will hold more pennies.

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

• Put straw outside of the boat to
• Cross the straws inside of the boat
• Make a standard boat to balance
• Make high enclosure

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

• do not break it before the experiment.
• Increase reinforcement to float the boat.
• Increase the area of the bottom.
• Increase the enclosure.
