In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.
