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.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

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, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
