9. Modeling Waves

Students learn about the differences between S-waves and P-waves that move through the inner part of the earth and are created during earthquakes. Introduction S-waves and P-waves, collectively known ...

10. Liquefaction

Students explore how vibrations can make solid ground very unstable. Introduction Liquefaction occurs when vibrations from seismic waves increase water pressure between soil grains, transforming ...

11. Sound = Vibration, Vibration, Vibration

In this demonstration, students use their bodies to model vibrations that lead to sound waves. Introduction Three things vibrate when sound is created: the source object the molecules in the ...

12. Modelling A Sound Wave

Use a stretched Slinky to model sound waves moving through a material. Introduction When you squeeze the Slinky's coils together at one end (compression), this causes the coils in front of them to ...

13. Speaking Involves Air, Vibration, and Muscle

... This in turn makes the air surrounding the rubber vibrate, propagating waves through the air to your ears, translating into sound. When blowing through their "fart whistles," students get to both see ...

14. Feeling The Vibes!

In this activity, students get the opportunity to see and hear sound waves by experimenting with tuning forks. Introduction A tuning fork is a two-pronged fork with the prongs (tines) formed from ...
