Icy Investigations
Source Institutions
In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.
Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
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.
Hot Equator, Cold Poles
Source Institutions
In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.
Parachutes
Source Institutions
In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.
Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
Exploring Products: Nano Sand
Source Institutions
In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.
Egg Drop
Source Institutions
In this activity, kids make and play with Ooze before testing the material in an egg drop!
Exploring Materials: Liquid Crystals
Source Institutions
In this activity, learners discover that the way a material behaves on the macroscale is affected by its structure on the nanoscale.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).
Smelly Balloons
Source Institutions
In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.
Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
Exploring Tools: Special Microscopes
Source Institutions
In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.
Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Divers
Source Institutions
Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.
