Strengthen a Paper Bridge
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp
Kites
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Kites) is a full inquiry investigation into how a kite’s shape affects its performance.
Paddle Power
Source Institutions
In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.
Kinetic Sculpture
Source Institutions
In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.
Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
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.
Sky Glider Challenge
Source Institutions
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.
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
In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.
Blimp Jet Challenge
Source Institutions
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.
Popsicle Bridge
Source Institutions
In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit
Sail Car Design
Source Institutions
This activity (on page 3 of the PDF under GPS: Sailboat Design Activity) is a full inquiry investigation into design optimization.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
Lift Off!
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
