Sea Level: On The Rise
Source Institutions
Learners will understand the relationship between climate change and sea-level rise.

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.

Drinking Straw Oboe
Source Institutions
In this quick activity (page 1 of the PDF under SciGirls Activity: Music and Sound), learners will construct an oboe-like instrument from a plastic drinking straw by cutting the end to split it into t

Coffee-Can Cuíca
Source Institutions
Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

Good Vibrations
Source Institutions
In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.
Splitting White Light
Source Institutions
In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

A Slime By Any Other Name
Source Institutions
This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

Gearing up with Robots
Source Institutions
In this activity, learners experiment with gear motion to understand how gears work to change the amount of force, speed, or direction of motion in machines.

Falling Rhythm
Source Institutions
Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.

How Do We Convert Mechanical Energy into Electrical Energy?
Source Institutions
In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

Which Parachute
Source Institutions
In this activity, learners will engineer three different parachutes to test how well each one works.

Radioactive-Decay Model: Substitute coins for radiation
Source Institutions
Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

Pop Rockets
Source Institutions
Learners place water and part of an antacid tablet in a film canister. The reaction creates a gas reaction that launches the film canister like a rocket.

Static Electricity
Source Institutions
In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.

Make Your Own Rainstick
Source Institutions
In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.

Make and Fly a Helicopter
Source Institutions
Learners follow the template to build and fly a paper helicopter.

Sky Glider Challenge
Source Institutions
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

Straw Pipes
Source Institutions
Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

Black Holes: No Escape
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with marbles and weights to discover some basics about gravity and black holes.
