Fused Plastic Wallet
Source Institutions
In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Shipping for Survival
Source Institutions
In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

Why Circulate?
Source Institutions
In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

Engineered Music
Source Institutions
In this activity, learners explore how musical instruments are engineered.

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.

Drugs, Risks and the Nervous System
Source Institutions
In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

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.

Be a Scanning Probe Microscope
Source Institutions
In this activity, learners investigate Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

Water Illusions: Refraction & Magnification
Source Institutions
Learners demonstrate how water can distort, refract and magnify light.

Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

Dry Ice Comet
Source Institutions
In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.

Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.

Carbon Sequestration
Source Institutions
In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

Kool Colors
Source Institutions
Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
