An Introductory Lesson Liberty Elementary School November 6 & 9, 2007

By the end of this lesson you will… Understand how satellite images are used by the program Google Earth to make 3-D digital maps. Open and run Google Earth Explore your area with digital images Learn the basics for navigating and saving information in Google Earth

What is Google Earth? An internet search engine Collection of satellite images A powerful tool for studying anything and everything about the earth A resource for a community of users to share information

How does it work? Satellites Cameras Computers People

Why do we need to use it? See our whole world Find information quickly Make Predictions Understanding!

Lesson 2: The Geology Field Trip Continued Today students will: Review the skills learned on Tuesday using Discuss their field trip around Frederick County and locate on satellite images the places they visited in real life. Visit places around the planet that are similar to the places visited in Frederick County and compare their similarities and differences. Write about what they find using a “blog”

1. “Go the Distance” usingtech2teach.tumblr.com Just how far across Frederick County did you travel on this Geology Field Trip? Here’s a task to find out: Put a thumbtack at High Rock, Cascade, MD. Put another thumbtack at Point of Rocks, MD Make sure you select both thumbtacks in your Search window so they show up on the map. Measure the distance between the two points using the ruler tool. BONUS: Use “Directions” to find out the true distance that it would be to drive between those two points. Post your answers to the blog! usingtech2teach.tumblr.com

2. “Down in the Valley” usingtech2teach.tumblr.com The Monocacy Valley is formed by the Monocacy River. What do you think formed “Death Valley”? Find Death Valley National Park on Google Earth. What does it look like? Now find The Tennessee Valley Authority at this address: 2805 N Highway 92 Jefferson City, TN 37760 Why do these two valleys look so different? Share your ideas on the blog. usingtech2teach.tumblr.com

3. “I’ve been to the top of the mountain…” This week you reached the summit of High Rock and maybe even Sugar Loaf. But can you imagine summiting the tallest mountain on earth? Find Mount Everest, then activate the NASA layers. You’ll see a link to some information and images from the International Space Station. Can you find the exact height in feet of Mount Everest from this information? When you do, post it to the blog along with your guess for the height of Sugar Loaf Mountain. http://eol.jsc.nasa.gov/EarthObservatory/OnTopoftheWorldEverestandMakalu.htm usingtech2teach.tumblr.com

4. “Have you checked your monodnock?” Sugarloaf Mountain in Frederick, Maryland is a “monodnock”. So is Uluṟu, also known as Ayers Rock. It is a large sandstone rock formation in the southern part of the Northern Territory, central Australia. It lies 335 km (208 mi) south west of the nearest large town, Alice Springs; 450 km (280 mi) by road. http://en.wikipedia.org/wiki/Uluru Use the Google Earth ruler to measure across Ayers Rock. Then do the same for Sugarloaf. Report your findings on the blog. Photo from http://en.wikipedia.org/wiki/Uluru usingtech2teach.tumblr.com

5. “What? It’s A Just a Big Hole!” This has to be one of the coolest things I have ever seen in the world. It’s every teacher’s dream to take their class on a field trip to the Grand Canyon, but for now… this is the best we can do. Go to Tuba City, AZ with the search window. Then activate all of the Gallery layers. About 43 miles to the WEST of Tuba City is the “Angel’s Window” photo that you can fly into. Check it out, then tell us what you think on the blog! usingtech2teach.tumblr.com

6. “Ring of Fire” usingtech2teach.tumblr.com Scroll around the globe to the Pacific Ocean, then zoom in on Hawaii. Find the “Big Island of Hawaii” and look for the volcano Mauna Loa. Turn on ALL LAYERS in the layer window, then activate the National Geographic layers under gallery. Select at least 3 links that you would like to read, then summarize the information you learned on our blog. You can also read about the volcano from the Smithsonian link. usingtech2teach.tumblr.com

7. “What’s the Point of Rocks?” Use the search window to find the town of Point of Rocks, MD. Look closely at the image, choose the layers for “Roads”, and then look between the highlighted roads and the river. What other form of transportation can you see? Make a mental list of the different forms of transportation you see going through Point of Rocks, then visit Chicago, Illinois (3D Buildings!) How are these two cities similar? Write about it on the blog. usingtech2teach.tumblr.com
