In this activity, learners explore what happens when polarized white light passes through a sugar solution.

This lab activity has learners create a pendulum with a one-second period.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

Did you know that a Slinky makes a handy model of earthquake waves?

Play with a slinky and make transverse waves. In this simple Exploratorium Science Snack, learners will experience making waves and will learn the different parts of a wave.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.

In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

In this activity about light and perception, learners create and observe moire patterns.

This activity was designed for blind learners, but all types of learners can model how vibrating particles, such as in a sound wave, bump into other particles causing them to vibrate, and that the vib

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.
