Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...

Steer young minds to build better boats. Future engineers first spend a few days exploring the TinkerCAD software and completing some embedded lessons. They then design sea crafts with buoyancy in mind and print them using a 3-D printer.

Students experiment with buoyancy as a force. In this buoyancy instructional activity, students access an assigned website to examine the sailing vessels that came to the New World. They work as teams to build boats out of aluminum foil...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Learners construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

Each student uses a small quantity of modeling clay to make a boat that will float in a tub of water. The object is to build a boat that will hold as much weight as possible without sinking. In the process of designing and testing their...

Hands-on challenge to build an unsinkable boat out of straws and plastic wrap that can hold twenty five pennies. Provides full list of materials with ideas on how to build, test, evaluate, and redesign it if necessary. Also, includes...

Students use modeling clay, a material that is denser than water and thus ordinarily sinks in water, to discover the principle of buoyancy. They begin by designing and building boats out of clay that will float in water, and then refine...

Students explore material properties in hands-on and visually evident ways via the Archimedes' principle. First, they design and conduct an experiment to calculate densities of various materials and present their findings to the class....
