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.
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.
Feel the Heat
Source Institutions
In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.
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.
Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.
Convenient Carrier
Source Institutions
In this design challenge activity, learners invent a convenient way for someone using crutches or a wheelchair to carry small personal items.
Slide Rules
Source Institutions
Learners make their own simple slide rules out of paper and learn how they work.
Cup Draw (Low Tech)
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.
Cup Draw
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.
Secret Writing Devices
Source Institutions
In this activity about encryption, learners cut out a secret decoder badge from a handout and use it to encode messages to each other.

Source Institutions
In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.
Cardboard Sculptures
Source Institutions
Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
Speedy Shelter
Source Institutions
