This activity lets you program your 'robot' (a willing friend) to pick up and dispose of some 'toxic waste' using as few commands as possible.

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

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this design challenge, learners will use computational thinking to design their own board game.

If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.

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.

Learners follow the template to build and fly a paper helicopter.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

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 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 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!

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.
