Waves: An Alternative Energy Source
Source Institutions
In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.
Your Blind Spot
Source Institutions
In this activity, learners will explore how their own eyes work by experimenting with their photoreceptors.
Photosynthetic Pictures Are Worth More Than a Thousand Words
Source Institutions
This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
String Thing
Source Institutions
String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.
Resonant Rings
Source Institutions
Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.
Exploring the Nanoworld with LEGO Bricks: Structures and Their Construction at the Nanoscale
Source Institutions
In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.
Metal Noise Maker
Source Institutions
In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.
How Do We Find Planets Around Other Stars?
Source Institutions
This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.
Polarized Sunglasses
Source Institutions
In this activity, learners explore how polarizing sunglasses can help diminish road glare.
Whale Cart
Source Institutions
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).
Writing for Night Vision
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Forensics), learners will use a home video camera with a “night vision” mode to test how various inks appear outside the spectrum of visibl
Laser Projection Microscope
Source Institutions
In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.
Doppler Effect
Source Institutions
Sound changes pitch relative to how you or the source of the sound is moving. Use this simple activity developed by the Exploratorium to experience the Doppler Effect yourself!
Sound Off!
Source Institutions
This activity includes several games about animal sounds. Using their sense of hearing and communicating with various kinds of noisemakers, learners role-play predator and prey.
Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Coffee Filter Rainbows
Source Institutions
In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.
Let's Make Music
Source Institutions
In this activity, learners will create their own percussion instrument with recycled materials. Learners will explore design, fabrication, cause and effect and sound through this activity.
Make a Green Gumball Black
Source Institutions
In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!
