Lessons
Lesson Title: Alaskan Earthquakes
Abstract:
8th grade science – Earth Science, Earthquakes, one blocking period up to two weeks
Standards and GLE’s addressed in this lesson
State (Science Content - B, C, D):
State (Inquiry & Process, Technology, Culture, History and Nature of Science – A, E, F, G):
Materials Needed:
Large plastic and metal slinkies
Corn Starch
Water
Plastic Beakers – 250ml
Science notebooks
Colored pencils
Anchorage cross section handout
Maps of Anchorage and other AK Regions
Computers with Google Earth
MapTEACH software
GPS devises
Digital Audio Recorders and Cameras
New Vocabulary:
Seismic Waves, P waves,S waves,Surface Waves,Tsunamis, Epicenter, Liquefaction
Gear Up:
Materials: TD video - 1964 Alaska Earthquake
Timeline:10-15 minutes
Short Free write/Discussion on the 1964 Earthquake to elicit prior knowledge and then viewing the 1964 Alaska Earthquake video from TD. Then a quick post write on what they learned from the video.
Exploration:
Materials: Slinkies for every pair of students
Timeline:5 minutes – experimenting with slinkies to make different types of waves
Concept Introduction:
Materials:Slinkies, projector/smartBoard
Timeline:20-25 minutes – demo and practice of different seismic waves –observations in science notebooks. Comparison of quakes using the richter scale, historical records, and photos.
Concept Application:
Materials:Anchorage Cross Section Handout
Timeline:30-45 minutes – Students draw and label an imaginary earthquake occurring near Anchorage on the handout. Drawings should include the magnitude on the richter scale, all the seismic wave types, and damage to the city.
Concept Application:
Materials:
Maps of Anchorage and other Alaskan regions
Optional:
MapTEACH software
Google Earth
GPS
Digital audio recorders
Digital cameras
Computers
Timeline:1-2 weeks – Students interview family members, elders, teachers, etc. about 1964 earthquake, or another recent earthquake. If possible, students can check out GPS devices and mark locations of events before uploading them to the computer to create their maps (using the MapTEACH software or Google Earth). Students then create a map of the event on a poster or using the computer. Students should include pictures (drawn or photographs), interviews (transcribed or audio links), and other pertinent background information and research. Students then present information to the class (poster or computer presentation).
Additional Information for teachers: The last concept application could be applied to a variety of events, including tsunami, flooding, glaciers/ice floes melting, population declines, permafrost damage, etc. This could be used as part of a Climate Change unit to share stories from around Alaska and the rest of the world.
Blog Reviews
Woven Ideas and Practices:
This blog has a wonderful layout, with a nice wide format that shows off the colorful and well-chosen photos. I had a lot of trouble with the skinnier blog format that I chose, as well as the arrangement of my photos, and if I do another blog I would like it to be more like this one. I also like how each post is broken up into the explain/extend/evaluate categories. Misty does a great job of making her blog personal, informative, and concise. I enjoy the fact that she doesn’t spend a great deal of time re-wording information from the Explore Alaska blog, and instead builds on knowledge gained from there and adds in her own thoughts.
Dan's AK Connections:
I chose Dan’s blog to review because of my ties to Southeast Alaska, as well as the interesting content and conversational nature. He always includes great photos and ties the information back to the education of his 5th grade students. I appreciate how he always includes some stories and information from Southeast, which helps to personalize the information and make it relevant. The student generated learning center for Earth Day is an excellent idea. This seems like a great way to make age appropriate information on global warming accessible to the other grade school students in the school.
