Boat Launching-Science

Designing We wanted...•2 bottles•4 balloons•Add more vinegar and baking soda than it called for•Tape everything together

We ended up with…•2 bottles•3 balloons•Same amount of vinegar and baking soda it called for•Taped everything together•Chop sticks on the sides

The Process of Experimenting

When we first built our boat it could floatWe discovered that the balloons were lifting up the boatSo, to make it lay nicer we took some off

When we first built our boat it couldn’t move properlyWe discovered that the amount of baking soda and vinegar it called for didn’t workSo, we changed the amount by adding more

Modifications Made

•We had to change some of the design•Had to place it in the boat differently•Had to change the jobs that were assigned•Added different materials to the boat

Energy MapGravitational-the

vinegar falls out of the bottle

Elastic-the balloons that help the boat float are

stretchy

Sound-when the boat shoot across

the water

Chemical-we have to add baking soda

and vinegar.

Motion –when we have to pull back

the cap
