Exploring Size: Scented Balloons
Source Institutions
In this activity, learners use their sense of smell to explore the world on the nanoscale.
Water Drop Races
Source Institutions
In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.
Fading Dot
Source Institutions
In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.
Exploring the Solar System: Stomp Rockets
Source Institutions
In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can
The Amazing Water Trick
Source Institutions
Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.
Valves and Pumps: A Demonstration
Source Institutions
This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.
Solar Flare Flip Book
Source Institutions
In this activity, learners make their own flip book that shows real solar flares erupting from the Sun in November 2000. Step-by-step instructions are included with photos.
Glider
Source Institutions
In this activity, learners construct a paper glider to experiment with aerodynamic forces.
Dancing Spaghetti
Source Institutions
In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
Make a UV Detector
Source Institutions
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.
Non-Round Rollers
Source Institutions
Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.
Stereo Hanger
Source Institutions
In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.
Peanut Butter and Jelly Robot
Source Institutions
This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.
Build a Soundscape
Source Institutions
This is a virtual representation of a sound mixer containing pre-looped sounds of animal, insect, and environmental noises.
Some Sums
Source Institutions
In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.
Fun Fruit: Advanced
Source Institutions
This math challenge, played with two players or a whole group, engages your problem solving skills.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
Six Squares: Geometry and Design
Source Institutions
In this activity, learners take a turn contributing a closed figure made of six squares to a large grid; each must be different from all the others on the grid so far.
Musical Coat Hangers
Source Institutions
Discover how sound travels and what materials make better sound conductors. Can you hear better with your fingers in your ears? Find out with a coat hanger and some string!
Exploring the Solar System: Big Sun, Small Moon
Source Institutions
“Exploring the Solar System: Big Sun, Small Moon” is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomena using familiar objects—a tennis bal
