Interference in a Ripple Tank
Source Institutions
In this optics activity, learners explore interference by adding wax blocks to a ripple tank.
Erupting Fizz
Source Institutions
This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.
Ready, Set, Fizz!
Source Institutions
In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
Cycles in the Cards
Source Institutions
In this "game," learners explore and relate the evolution of stars to a Navajo creation story. The story is written on a series of cards, which are laid on a table as the story is told.
Bonseki Salt Art
Source Institutions
In this activity learners will be creating art using a traditional Japanese art style.
Hot and Cold: Endothermic and Exothermic Reactions
Source Institutions
Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.
Toilet Paper Solar System
Source Institutions
In this activity, learners build a scale model of the solar system using a roll of toilet paper.
It's A Gas!
Source Institutions
Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.
All Mixed Up!: Separating Mixtures
Source Institutions
Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.
Solar Convection
Source Institutions
In this activity, learners add food coloring to hot and cold water in order to see how fluids at different temperatures move around in convection currents.
Make Pan Pipes
Source Institutions
This is a simple activity for learners to create a traditional musical instrument. Pan Pipes have developed all over the world in different cultures, from South America to Greece and China.
Shrinkers
Source Institutions
Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
Concentrate: Concentrations and Reaction Rates
Source Institutions
Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.
Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
Measure the Sun's Size
Source Institutions
In this activity, learners make their own pinhole viewer in order to measure the size of the sun.
Papermaking at Home
Source Institutions
Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.
Clean Me Up, Snotty
Source Institutions
Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
Sun Cookies
Source Institutions
In this activity, learners use candy pieces and a cookie to make an accurate model of the Sun they can eat. Parts of the delicious model include solar granules, sunspots, and solar prominences.
