Boat Launching-Science

By: Maddie Cooper

Day 1 Day 2 Day3

The process of experimenting

Our first boat: It couldn’t float because… The secret potion didn’t work Balloons too big so it was pulling boat up, so

cap wasn’t in water To make it better we… Added a paddle (fought against secret potion,

if potion worked anyway)

Day 1

Modified boat two by… Adding paddle to front to work with potion

(if potion worked) Paddle kept hitting the bottom

Day 2

We made a whole different boat called the Speed Splash!

It works because… We have a balloon that deflates When balloon deflates the air pushes the

boat The water bottle shape helps the boat cut

through the water easily The chopsticks helps keep it balanced

Day 3

Here are some materials we used on our boat:

Balloon Water Bottle Chopsticks Tape Go Speed Splasher!!!
