The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.
The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
Your Age on Other Worlds
Source Institutions
Did you know that you would be a different age if you lived on Mars? It's true!
Quadraphonic Wind
Source Institutions
In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.
Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.
A Cubic Foot Per Second
Source Institutions
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
Whose Fault Is It?
Source Institutions
In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.
Engineered Sports
Source Institutions
In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.
Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
Crunch Time
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.
Colors, Colors?
Source Institutions
In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th
My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
Making Music in Nature
Source Institutions
In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.
Motion Madness: Choose the Winner
Source Institutions
This is an online game that explores speed, range and momentum. Learners will pick the winners in a 16-team tournament in 3 events: Tug-o-war, sprint, and marathon.
Mid-Air Maneuver: Skateboard Science
Source Institutions
To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.
Experiencing Parallax With Your Thumb
Source Institutions
In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.
Hanford at the Half-Life Radiation Calculator
Source Institutions
This quiz lets you estimate your annual radiation exposure.
