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.

Tiny Particles, Big Trouble!
Source Institutions
In this activity, learners discover why some nanoscale science and technology is done in the controlled environment of a clean room, what clean rooms are like, and how scientists help keep the clean r

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

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.

Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

Biomimicry: Synthetic Gecko Tape Through Nanomolding
Source Institutions
In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
