In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
