In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.

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

In this engineering activity, challenge learners to make a "grabber" that can pick up trash. Learners use simple materials to create pinchers that can grab small items.

In this activity, learners investigate balance and symmetry by designing a symmetrical butterfly, using a paper cutout.

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 design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

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

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

In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.

In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.
