Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Benham's Disk
Source Institutions
In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
Spherical Reflections
Source Institutions
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
Safer with Science-Masks
Source Institutions
Why should we wear masks? Do masks work? Do some masks work better than others? Learners find out in this activity.
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
Circuit Sense
Source Institutions
In this activity about electricity, learners identify closed and open circuits. First, learners examine and label diagrams of open and closed circuits.
Anti-Gravity Mirror
Source Institutions
In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.
Falling Feather
Source Institutions
In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall
Tasty Buds
Source Institutions
In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
Does the Moon Rotate?
Source Institutions
This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.
Penny Battery
Source Institutions
In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
What Causes Wind?
Source Institutions
In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.
What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.
Turbidity
Source Institutions
This is an activity about turbidity, or the amount of sediment suspended in water.
Carrying Charges: Testing for Conductivity
Source Institutions
Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
