Angle Hunting
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment. Learners will observe that angle measurements do not change with distance, because they are distance invariant, or constant. Note: The "Pocket Protractor" activity should be done ahead as a separate activity (see related resource), but a standard protractor can be used as a substitute.

Anti-Gravity Mirror
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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. To make the effect more dramatic, cover the mirror with a cloth, climb onto the table, straddle the mirror, and then drop the cloth as you appear to "take off." This resource contains information about how this trick was applied during the making of the movie "Star Wars."

Rating
0.0 stars

This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying. When we tried this trick on the Exploratorium's exhibit floor, we gathered a crowd of visitors who wanted to know what we were doing. We explained that we were engaged in serious scientific experimentation related to energy transfer. Some of them may have believed us. If you'd like to go into the physical calculations of this phenomenam, see the related resource "Bouncing Balls" - it's the same activity but with the math explained.

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. Learners experiment with the speed of rotation and direction of rotation to observe varying patterns. Use this activity to explain to learners how our eyes detect color and how different color receptors in the eye respond at different rates.

Cardboard Automata are a playful way to explore simple machine elements while creating a mechanical sculpture. This activity was inspired by the Cabaret Mechanical Theatre, a group of automata builders based in England. Artists like Paul Spooner, Keith Newstead, and Carlos Zapata build beautiful narrative pieces using elegant mechanisms based on cams, gears, springs, and linkages. Working with simple materials, this activity is easy to get started, and may become as complex as your mechanical sculpture ideas.

In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes. They rinse half the pennies with water, then compare the rinsed pennies to the unrinsed after all pennies sit and dry for about an hour. Learners also observe what happens when they submerge a screw and nail in the liquid compared to a nail only half-way submerged.

In this activity, learners use their hands as tools for indirect measurement. Learners explore how to use ratios to calculate the approximate height of something that can't be measured directly by first measuring something that can be directly measured. This activity can also be used to explain how scientists use indirect measurement to determine distances between things in the universe that are too far away, too large or too small to measure directly (i.e. diameter of the moon or number of bacteria in a volume of liquid).

Rating

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer. Most common batteries--such as car batteries and the batteries inside a flashlight--work on the same principle that the pickle battery works on: two metals suspended in an ion-rich liquid or paste separate an electric charge, creating an electrical current around a circuit. In this activity, the pickle provides the ion-rich liquid - pickles contain salt water, which is rich in ions.

Light painting is a creative activity that involves creating striking images and illusions using a camera, a light source, and a little practice. Light paintings may be literal representations or impressionistic, color-filled images. When the camera shutter is open (and the room is dark) the film or digital sensor acts like a blank canvas onto which learners "paint" with a flashlight.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead. Natron is made up primarily of sodium carbonate (a very efficient, but relatively expensive, dehydrating material), with about 17% sodium bicarbonate (baking soda). This activity explains how to create your own fish mummy using common baking soda!

This activity shows you how to make a mold terrarium using a jar and leftover food. Learners explore mold, an "icky but necessary" thing that helps living matter rot, return to the soil, and provide nutrients for other plants. If you use a variety of food scraps, with preservatives and without, you'll see the different kinds of mold and be able to compare the rate of growth on various foods. Note: don't put meat or fish in your mold terrarium--after a few days, these would start to smell very, very bad.
