I know, I know, I know, I have been terrible at keeping up with weekly reporter updates. It seems that my life and time have been submerged in the raging river that is the school year. The first 9 weeks is almost over. Really it is quite inconceivable that it has already been almost 2 months since we began the year. Nonetheless, here we are. Look for several additions to the blog this weekend as I get caught up on updates that have been sitting in the cellar.
A couple of weeks ago Earth and Environmental Science spent a good amount of time looking into landslides, mudflows, and other related natural disasters. All of which have the capability of creating a very bad day for your village. This is the third time that I have had the opportunity to teach this unit. As is the case with many units the students complete a project to demonstrate what they have learned through their lessons. For this particular unit, students are responsible for creating websites that could be used to educate the public about the dangers of mass movements. Below you can find links to some of the more outstanding submissions.
Reflecting on the week's lessons (9/4-9/7), we have weekly reporter submissions from TyQwisha Gwynn, Gabby Garcia, and Jarrett Goins.
This week we studyed on mass movements. The 4 movements are creep,mudflow,slump,and landslides. The 2 main movements are landslides and mudslides. A landslide is when the earth slides down.Mudslides is when the earths sediments move downward.We also discussed the difference between erosion and weathering. Erosion is the moving of the sediments. While weathering is when its actually breaking down.And that is about all we learned this week.
What I learned this week was about mass movements. The mass movements are landslide, lahar, mudslide, and avalanches. Landslides is the sliding down of a mass of earth or rock from a mountain or cliff. Lahars they are a form of mudslide or landslide that needs to be triggered by volcanism. Mudslides are a fluid or hardness stream or avalanche of mud. Avalanches are a mass of snow, ice, and rocks falling rapidly down a mountainside. Then we learned about water and man. Water increases the weight of soil. Heavy soil is more likely to move downhill. Water reduces the friction between sediment particles and makes sliding much easier. Man is anything that removes vegetation, removing the base of a hill.
In class on Tuesday September 4, 2012 we had to identifyfactors that affect mass movements. Also we had to analyze therelationships between gravity and mass movements. Anddetermine the difference between the major types of massmovements. We also began our projects on which we had to createa website on (www.weebly.com) to show your knowledge on themass movements. They are Landslide, Slump, Mudflow, andCreeps.
