The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
Pencil Drop
Source Institutions
In this demonstration, learners observe as a bottle is placed on a table with wooden hoop balanced on top and a pencil balanced on top of the hoop.
Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.
Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Become a Master of Inertia
Source Institutions
In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.
Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.
One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
Mirrorly a Window
Source Institutions
In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.
Penny Cup Game
Source Institutions
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
A Stand-up Egg
Source Institutions
In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.
Phantom Phlame
Source Institutions
In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.
Magic Disc
Source Institutions
In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.
Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.
Arrows
Source Institutions
In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.
Invisible Ink
Source Institutions
In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a
Lifting Lemon
Source Institutions
In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
Magical Match
Source Institutions
In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.
Test Your Lung Power
Source Institutions
In this activity, learners try to blow up a balloon hanging inside of an empty bottle.
Inertia Coin Stack Challenge
Source Institutions
In this activity, learners experiment with inertia by performing an easy and hands-on investigation with a playing card and a stack of coins. The activity includes an accompanying Mr.
