This project is an introductory investigation of buoyancy and the shape of different boats for different purposes.
With an adult’s help cut different hull shapes from balsa wood, cardboard, or Styrofoam trays.
Experiment with each to see how quickly they can move across the water when given a little push. Once you have completed your exploration of different hull shapes experiment by adding keels.
If you are interested in experimenting even more with your boats you could investigate rudders and tillers. You may want to take photographs as you complete your experiments to use for your science fair poster or presentation.

When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. The goal is that the student will learn through their own experimentation the reason boats are shaped and engineered the way they are and gain scientific knowledge around a real-world concept.
Some of the parts of the boat that play a role in the way the boat moves are the hull and keel. Science Education, teaches and develops curriculum for Pre-Kindergarten through 6th grade science, in addition to helping to coordinate her schoolas annual Science Day bringing the student body together to present their work in science and participate in a school wide science project.
By experimenting with the shape and materials used to make these parts of the boat we can determine which shape is best for what purpose, and understand science concepts such as buoyancy and water displacement.

Create a chart like the one you used in your hull experiments to keep track of your tests and observations. Sarah has experience teaching science at museums, nature centers, and environmental education centers in addition to her work as a classroom teacher.
