In this lab/demonstration the teacher will demonstrate how convection currents in the atmosphere occur. This demonstration is very visible and can easily be done without any special equipment except for a hot plate. Students will fill out a science lab sheet that has them hypothesize and then diagram how air currents are moving. As part of the lab students will get some reinforcement as to what high and low air pressures are and what causes them. Students will also be able to demonstrate their previously gained knowledge of density.
In this video of the 2010 Haiti Earthquake students will see some the of shaking that occurs. This is where I discuss P and S waves as well because you can actually see when the two wave hit. Also there is footage of one of the buildings being collapsed. I show this video as part of my Daily Dose of Destruction series.
In this video students will get a great view as to what liquefaction is during an earthquake. This video comes from the 2011 earthquake in Japan. One of the cool things about this video is that you can actually see the earth shift as is grinds the dirt squeezing the water out causing the liquefaction.
Students will be able to witness some video captured during the 1989 Loma Prieta Earthquake. I use this video as part of my Daily Dose of Destruction series when teaching about the destructive power of earthquakes.
In this video students will gain a better understanding of what seismographs, seismometers and seismograms are. As students study earthquakes they can use some of this information to understand how scientists use use seismic data to discover where earthquakes are located. This science video also talks about the different types of earthquake waves, P, S, and Surface waves.
In this video your earth science students will be able to witness a compilation of video from the 2011 Japan earthquake. In this video students will see that building can sway as the earth moves. They get to see a little liquefaction. There is some video of the tsunami that occurred. Most of the video show how earthquakes can be destructive. I use this video as part of my Daily Dose of Destruction series during my earthquake unit.
I show this video when discussing pyroclastic flows. This is a pyroclastic flow that killed a few people in Japan a couple of years ago. It is pretty impressive video as people try to protect themselves and outrun the flow. I also get to discuss how even though there are many warnings of a pending volcanic eruption occurring, it doesn't always mean that there will be advanced warning.
I show this volcanic eruption when trying to discuss the different types of eruptions. This one is called a lava dome eruption. Lava Dome eruptions stay pretty close to the vent and are very thick non explosive eruptions.
