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.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

In this seismic simulation, learners play a "who-dunnit" game to explore earthquakes.

Learners use beach profile data from a local beach or online data from Ocean City, Maryland to investigate coastal erosion and sediment transport.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Build your own version of the classic physics toy using simple materials.

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

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

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 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 activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this outdoor, beach activity, learners use tennis balls, water balloons and other simple devices to investigate the movement of waves and currents off a sandy beach.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.
