Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting activity, scholars explore buoyancy and the properties of air and water. They test cups to see...

Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

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...

How can you determine the maximum speed of a sailboat? A sailing presentation included with a straightforward lesson plan prompts learners to calculate the maximum speed of a sailboat with a displacement hull. The...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

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.
