In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this lab (Activity #1 on page), learners explore how we see color.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

In this activity, learners make a parachute out of tissue paper, tape, and string. Then, learners test their parachute to see how many paper clips it can carry.

In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!

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.

In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.

In this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.

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.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

This activity is a hit for family events and all ages—some will finish in 45 minutes; others can go on for hours.

In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
