Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
The Parachuting Egg
Source Institutions
In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.
Leaves: Designing Leaf Arrangements on a Branch
Source Institutions
In this hands-on activity, learners investigate the functional design of leaves on a tree.
Marble Run!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Luge) is a full inquiry-based challenge related to motion and design optimization.
Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Block Neighborhood

Build a Better Roof
Source Institutions
In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.
Roller Coasters
Source Institutions
In this activity learners will build roller coasters and test them using small balls or marbles.
Watercraft
Source Institutions
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.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
Touch Down
Source Institutions
