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

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

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.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.
