In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

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

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

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.

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.

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.

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 design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

In this activity, learners observe fly behavior and then build a flytrap.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

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

In this hands-on activity, learners investigate the functional design of leaves on a tree.

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 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 modify a cup so it can carry a marble down a zip line and also drop it onto a target.
