This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

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

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
