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

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

In this activity, learners explore why they can see colors in bubbles and why they change.

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.

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.

In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

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.

In this activity, learners will explore the insect life cycle by making a model.

In this activity about gravity (page 6 of the PDF), learners will come to understand how all objects will fall at the same rate, but that air will slow things down.

"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

In this activity, learners make a camouflaged butterfly to hide outside for others to find.

Up close, an array of dots could look random, but take a step back, and an image forms. By tracing over an image, learners can create their own dot based image.

Create beautiful spirals by drawing a straight line. This sounds crazy, but you can with a turntable (a record player or lazy susan), paper, and pen.

In this activity, learners investigate just how small a billionth of a meter is by attempting to cut a paper ruler down to a nanometer-sized sliver.

This demonstration activity models how Venus appears from Earth.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

In this activity, learners use sound to figure out, or infer, the position of objects. Learners create a maze inside a shoebox with blocks of wood.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.
