Homeroom • Planners out • On Today’s date write: Get Report Card Signed • I need the report cards back tomorrow! Please fill out your planner for the entire week! January 14-18 MONDAY SE: Sedimentary Rock Fossils HW: MS 209-212 due Thur TUESDAY SE: Weathering,Erosion Deposition Lab HW: Due Thurs THURSDAY SE: Landforms made from W.E.D. Stream Table FRIDAY SE: HW:Handwrite page 1-2 notes HW: Quiz Bill Nye Erosion WEDNESDAY SE: Landforms made from W.E.D. HW: Tutorials everyday 7:00-7:20 New EARTH SCIENCE NOTES When you are finished with you planner: Get your binder and MS book! Tuesday Homework • Open your MS book to page 209. • Mark it with a sticky note • 20 questions due on Thursday, please draw pictures MS book now on the floor Get out your binder- open up to FOSSIL EVIDENCE Write this in binder Fossils are found in Sedimentary Rock! 1 dead organism + layers of sediment + Heat + Pressure + Millions of years = Fossil How do you make a Fossil? An Organism Dies It’s Covered with Sediment It’s covered with MOre sediment It’s covered with MORE sediment What else do you need? Heat and Pressure Heat and Pressure Heat and Pressure Lot’s of time Lot’s of time Lot’s of time What are you going to get A FOSSIL! Let’s make a fossil • Using cereal and gummies we are going to make a sedimentary rock model 1. 2. 3. 4. 5. 6. 7. 8. 9. Anti- Bacterial your hands Look in the microscope at the detail of the fossil Get a cup Add a layer of “sediment” Add 1 “dead organism” Add a layer of “sediment” Add 1 “dead organism” Continue until layers are complete Now add Heat and Pressure 10.Now wait at your desk…Millions and Millions of years Once everyone is at their desks Now very carefully you may “dig out your fossil” And you may put the sedimentary layers in the cave of your mouth and let the river wash it down the canyon. How do fossils help us to learn more? Thinking like a paleontologist How do you know? First… Look at the bear in this picture. What environment do Would the bear on the left live in this warm environment? you predict it lives in? ….Or, would the bear on the left live in this colder environment? How did you decide which environment the bear lives in? http://www.arctic.noaa.gov/gallery.html Let’s Try Again Would the tree live in this environment? Look at these pictures of things that come from a tree. Make a prediction about the environment where you would find this tree. http://www.nps.gov/olym/wic/gallery.htm … or, would the tree live in this environment? This is more difficult isn’t it? Why? What would help you decide on the correct environment? http://www.nps.gov/yell/slidefile/index.htm Now you are the paleontologist This is the environment where you are looking for fossils. Here in an example of the kinds of fossil your team has found. What do you think the environment might have been like in the past? Now you are the paleontologist You just found the plant fossils, on the left, in an area where it is now hot and dry like the picture on the right. What predictions can you make about what the environment might have been like in the past? “Small animal fossils are one of the best indicators of prehistoric ecosystems and environments. For example, a fossilized frog tells scientists that the habitat within which it lived must have been wetter because the frog was dependent on permanent water to breed. In other words, it was a captive within its environment.” A quote from a Scientist from the Page Museum's Laboratory http://www.tarpits.org/education/guide/index.html Once Upon a Time Wooly Mammoth Asian Elephant http://www.bbc.co.uk/radio4/science/frontiers_20020515.shtml How are these two animals the same? How are they different? Once Upon a Time – A Look at the Horse Horse B Horse A Change Over Time – A Horse’s Foot Note how the distance of the wrist bones from the ground changes. What else has changed? wrist Adapted from Florida Museum of Natural History. For more information visit their website at http://www.flmnh.ufl.edu/natsci/vertpaleo/fhc/relatives1.htm Let’s Look More Closely How have the bones in horse feet changed over time? Why might this have happened? Adapted from Florida Museum of Natural History. For more information visit their website at http://www.flmnh.ufl.edu/natsci/vertpaleo/fhc/relatives1.htm Wrap-Up • Fossils are formed under very special conditions. • They give us clues about what life was like long ago. • Fossils also give us clues about the environment from a long time ago. • They help us understand that plant and animal species change over time. Why does that matter? Allows us to understand how events have changed the world Might prepare us for the future Helps us understand why our world is like it is.

Do bigger rocks or small sediment weather faster? I think that the bigger rocks will weather faster If I break the rock, instead of letting it dissolve. Write in your spiral the lab set up! Mouth, 2 tic tacs __________________ Write in your spiral the lab set up! 1. Put a tic tac in your mouth, do not bite it 2. Lightly swish it with your “river” in your mouth a. Think about your observations 3. Now swish it faster and hit your teeth (rocks)…do not break it a. Think about your observations 4. Now bite it and swish it a. Think about your observations 5. Swallow and write your observations Write in your spiral the lab set up! __________________ Summarize the tic tac lab, explaining what the tic tac represents and the limitations of this model.

Example- Rocks to sediment Example- Statue of Liberty How does water effect weathering? When water leaks into the cracks of rock and freezes the rock expands, then freezes And what about glaciers? Erosion • Process of moving sediment from one place to another Deposition Process of depositing sediment in a new location What New Landforms are Created by erosion and deposition? Underwater volcano Eroding force of a river channel Deposition of sediment at the mouth of a river A glacier stops moving forward and deposits the sediment it carried with it Changes to Earth’s Surface Weathering Erosion Deposition Landform Breaks Erodes Depositing Mountains Cracks Moves Drops Beaches Freezes Carries Removes Valleys Carves Flows New Locations Plateaus Expands Floats Rivers Stream Table- Demonstration Let’s Discuss what happens in the model!
