A demonstrator taps a glass beaker to find its natural frequency of vibration and then sets an oscilloscope and amplifier to produce a loud sound at that same frequency. The resonance created by exposing the beaker to the sound wave forces the glass to vibrate and distorts the shape of the beaker. The amplitude of the sound wave from the speaker is increased until the oscillation of the beaker exceeds the elastic limit of the glass and the beaker breaks.

What Causes a Volcanic Eruption?  
Video 
Observe how the continuous movement of Earth's tectonic plates results in volcanic activity. In a volcanic eruption, super-heated magma from within the earth’s upper mantle works its way to the surface. This most often occurs at tectonic plate boundaries, but some volcanoes can also form over 'hotspots', or weak areas in the earth's crust. 

Earthquakes
Video, images, vocabulary, reading and review questions 
An earthquake is sudden ground movement. This movement is caused by the sudden release of the energy stored in rocks. An earthquake happens when so much stress builds up in the rocks that the rocks break. Almost all earthquakes occur at plate boundaries.

Endangered Species: Worth Saving from Extinction? 
Video, student handouts, activity and facilitator guide
Throughout Earth’s history there have been five major mass extinction events—where a large percentage of species died out. Scientists estimate that we are in the middle of the 6th mass extinction event right now, where species are dying out at 1,000 to 10,000 times baseline extinction rates. Moral and ethical arguments to try to prevent species extinction include reasons like all life has a right to be here, or that we owe it to our grandchildren to protect species so they can see them in the wild. So, are species worth saving from extinction?

Activity: Conservation across Fence Lines
Interactive and facilitator guide
Public lands in the United States are often set aside for conservation of land and wildlife. In Nebraska, less than three percent of the land is protected public or conservation land. To protect at-risk habitat and species in Nebraska, innovative wildlife conservation strategies attractive to private landowners are needed. Private landowners committed to sustainability and interested in innovative approaches to land management have found that the common-interest community model can benefit wildlife populations and increase biodiversity on ranchland in the Nebraska Sandhills. For a fun, hands-on, real-world approach to understanding the common-interest community model, click “ENTER” below to play the Conservation Across Fence Lines interactive game.
