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.

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.

Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners will create a model rocket out of an inflated balloon attached to a straw on a taught string.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

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!

Learners design their own experiment to investigate how pollution diffuses through ground material.

Students design and build their own parachutes in this hands-on engineering project.

In this engineering activity, learners design their own board games.

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.

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

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

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 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 activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.

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
