Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.

Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

A Recipe for Air
Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Egg-cellent Landing
Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Hanging Around
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

Leaning Tower of Pasta
Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Hot Stuff!: Testing Ice
In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

What's Hiding in the Air?: Rubber Band Air Test
Learners build devices from rubber bands to test for invisible air pollutants.

Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

Make a Tikiville Teepee
Source Institutions
In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

Control a Bird’s Flight
Source Institutions
In this engineering design challenge, learners make a bird and then control its flight with attached strings.

Wire Maze
Source Institutions
Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

Design a Microexpression Zoetrope
Source Institutions
In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

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