I would love to hear about your experience with the earthquakes we have had in Utah. Leave a comment and tell me have you felt any of them? If so, where were you and what did you do? When I was doing research to try and answer my questions about earthquakes, I came across this cool website called Weather Wiz Kids. Check it out!
Looking at the pictures of animal evidence, (starting with the top left picture and going across) this is what I discovered... 1. Elk scat 2. Deer antler 3. Large bird nests or just clumps of branches...still not sure. 4. Deer scat 5. Robin's nest 6. Land snails Credits Information gathered from the following resources: Answers #1 and #4 Who Pooped? Lehmann, Steph. Who Pooped: Field Guide, Journal & Activity Book. Farcounty Press, 2019. Answer #6 Utah Division of Wildlife Resources, dwrcdc.nr.utah.gov/rsgis2/Search/Display.asp?FlNm=oreohayd. Found this hive when I was walking in my neighborhood! 1. Why is the lake so salty? 2. Do any animals live in the Great Salt Lake? 3. Has the size of the lake changed over time? 4. How deep is it? 5. Can you swim in it? I found almost all the answers to my question when I went to the EBSCO database I showed on the video. I just typed, "The Great Salt Lake" into Explora and here is what I found... Click here to see the site and be able to listen to the text. I have underlined a few of the important details below: The Great Salt Lake is saltier that the oceans because its water is not drained away by streams or rivers. The size of the lake depends on weather conditions. When there is little rain, the lake shrinks because of evaporation; when there is a lot of rain, the lake grows. In the 1980s, the lake was close to its largest size, about 2,400 square miles. The lake's normal size is about 1,700 square miles. In 1987, a pumping system was installed to control the level of the lake. There are no fish in the Great Salt Lake, only small brine shrimp. The lake is very easy to float in because of the salt content. The Great Salt Lake contains about 5 billion tons of minerals. In some areas, more than 25 percent of the lake is common table salt. The salt in the lake comes from the many minerals that are dissolved in the water. The Great Salt Lake is actually really shallow. The average depth is only 14 feet and the deepest part is 33 feet. You can swim in the lake and float pretty easily because of the salt. Some people enjoy sailing, kayaking, or boating on the lake as well.
Hi Students! A few of you guessed the rock from last week. If you thought it was obsidian, way to go! However, I had another discovery this week that made me question whether we were right about the rock being obsidian. I thought it was obsidian because of it's shiny, glass-like surface, but after doing more research and looking for more obsidian in my yard, I noticed a couple of things. First, I noticed that most of the other rocks around our house were sedimentary rocks, like sandstone and limestone. Obsidian is igneous (formed by the cooling of magma from a volcano). Second, as I looked for more obsidian, I started finding more small chunks that were shiny on some sides, but not all over. Finally, my husband reminded me that he had removed gravel and tar from our roof a few years ago and he thought the black rocks were actually dried tar. This week I'll be coming up with a test to figure it out, so stay tuned! Watch my experiment video and check out what happened! |
