Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
Inverse Functions: Pennies, Pressure, Temperature, and Light
Source Institutions
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.
Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Whirling Windmills
Source Institutions
In this activity, learners are challenged to design and construct a windmill to harness the power of wind.
Soaring Satellites
Source Institutions
Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.
Ping Pong Ball Shooter
Source Institutions
In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.
Aerogel
Source Institutions
This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.
Try Your Hand at Nano
Source Institutions
This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.
Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
Measuring the Wind
Source Institutions
In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.
Dough Creatures
Source Institutions
In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.
Plankton Races
Source Institutions
In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.
High Tech Fashion
Source Institutions
In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.
Can You Canoe?
Source Institutions
In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.
Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Nano Waterproofing
Source Institutions
This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
