Source Institutions
Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.

DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.

Exploring Earth: Investigating Clouds
Source Institutions
“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

Why Are Bubbles So Colorful?
Source Institutions
In this activity, learners explore why they can see colors in bubbles and why they change.

Soap Film on a Can
Source Institutions
The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

Mirror, Mirror on the Wall: Angles of Reflection
Source Institutions
In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

See It to Believe It: Visual Discrimination
Source Institutions
In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

How Loud is Too Loud
Source Institutions
In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

Clothespin Workout
Source Institutions
This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.

Designer Ears: Make “better” ears!
Source Institutions
Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.
Sea State: Forecast Conditions at Sea
Source Institutions
In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

Percentage of Oxygen in the Air
Source Institutions
In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Paper Cutting
Source Institutions
In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

Physics in the Kitchen: Sink or Swim Soda
Source Institutions
In the kitchen, learners can perform their own density investigation.
Bend It, Break It
Source Institutions
In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
