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

This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.

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.

In this activity, learners will create a speaker using a paper cup, magnet, and enameled wire. Also included in this activity is a Mr.

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 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.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.

In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.

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 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.

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.

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
