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.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
In the Toilet
Source Institutions
This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Biobarcodes: Antibodies and Nanosensors
Source Institutions
In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.
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.
Clap Sensor: Build a Sound Sensor Using a Pico Cricket
Source Institutions
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.
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.
Pendulum Snake
Source Institutions
In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
Water Fountain
Source Institutions
In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.
Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.
Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.
Investigating Ice Worlds
Source Institutions
In this activity about the solar system, learners use various light sources to examine ice with different components to understand how NASA studies planets and moons from space.
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.
Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.
Exploring Fabrication: Gummy Capsules
Source Institutions
In this activity, learners make self-assembled polymer spheres.
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.
