Sailboat Design
We're Max and Brian, and we both love to sail. When we're not sailing in our 15-foot boats, we sail models. We even sail them when we visit the California Science Center. There's a cool sailboat exhibit here, where you can make models of different shapes, sizes, and sail types. Our question was: which kind of boat sails faster, a single-hull or a double hull boat?

How would you investigate this question?
Take the time to carefully develop an investigation that answers Max and Brian's question. You may need to have a variety of boats of each type available to get a complete answer to your question. Since you can change so many properties about a boat (for example, its sail size and shape, its weight, etc), you need to design an investigation that makes a fair comparison between the two types of boat. Describe your investigation in your notebook and discuss it with your teacher, or go to Sailboat Design to learn what Max and Brian discovered.
