Zip Line
Source Institutions
In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).
Balloon Flinker
Source Institutions
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.
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.
Speedy Shelter
Source Institutions
In this design challenge activity, learners invent an emergency shelter that can fit a person and is sturdy and quick to build.
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Sky Floater Challenge
Source Institutions
In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
