(1) Steam engine cycle Pop-pop boats are a wonderful way to learn about the basics of a steam engine cycle. And, the come in a wide variety of styles.

Project Subjects - Science project ideas top - DNA structure - Optics, optical illusions - Water barometers

Regardless of the style, the underlying physics of the pop-pop boats is the same. Our tutorial on the flash boiler steam engine cycle that power these is found on the physics tutorials page.

For those who want to make their own boat, we have a tug boat kit. With the kit, you can put parts of the steam engine together yourself.

(2) Why boats float

A conceptual approach to the mysteries of Archimedes' Principle is found in The Amazing Book of Paper Boats. There are suggestions for at home experiments to prove the idea of buoyancy to yourself in the books introductory chapters.

There are 18 waterproof paper boats to fold and float. Each boat includes historical narrative and explanations of the pertinent nautical terms.

If you get a chance to go on a sail boat, take it! The entire boat is a marvelous demonstration of the science of classical mechanics.

(3) Buoyancy, acceleration, momentum

Experiment with a pop-pop or sail boat. Increase the weight of the boat.

Is is harder to get the boat moving? How is the overall speed of the boat affected? Does it sink?

Use your imagination. Be sure to record your observations. Then, compare your notes with the principles of buoyancy, acceleration, and momentum.
