Homeroom

1. Homeroom • Planners out • On Today’s date write: Get Report Card Signed • I need the report cards back tomorrow!

2. Please fill out your planner for the entire week! January 14-18 MONDAY TUESDAY WEDNESDAY SE: HW: SE: HW: SE: HW: Sedimentary Rock Fossils MS 209-212 due Thur Weathering,Erosion Deposition Lab Due Thurs Landforms made from W.E.D. THURSDAY FRIDAY Tutorials everyday 7:00-7:20 New EARTH SCIENCE NOTES SE: HW: SE: HW: Landforms made from W.E.D. Stream Table Handwrite page 1-2 notes Quiz Bill Nye Erosion  When you are finished with you planner: Get your binder and MS book! Tuesday

3. 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

4. Write this in binder Fossils are found in Sedimentary Rock! 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! 1 dead organism + layers of sediment + Heat + Pressure + Millions of years = Fossil

5. Let’s make a fossil • Using cereal and gummies we are going to make a sedimentary rock model • 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 • Now wait at your desk…Millions and Millions of years

6. 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.

7. How do fossils help us to learn more?

8. Thinking like a paleontologist

9. How do you know? Would the bear on the left live in this warm environment? First… Look at the bear in this picture. What environment do you predict it lives in? ….Or, would the bear on the left live in this colder environment? http://www.arctic.noaa.gov/gallery.html How did you decide which environment the bear lives in?

10. 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

11. 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?

12. 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?

13. “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

14. Once Upon a Time Asian Elephant Wooly Mammoth http://www.bbc.co.uk/radio4/science/frontiers_20020515.shtml How are these two animals the same? How are they different?

15. Once Upon a Time – A Look at the Horse Horse B Horse A

16. 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

17. How have the bones in horse feet changed over time? Why might this have happened? Let’s Look More Closely Adapted from Florida Museum of Natural History. For more information visit their website at http://www.flmnh.ufl.edu/natsci/vertpaleo/fhc/relatives1.htm

18. Wrap-Up Write this and draw sedimentary layers • 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.

19. Why does that matter? Write this • 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.

20. Do not throw away your cup Stack them and I will wash them STOP Think before you leave. • Did you put binder on shelf • Do you have your planner out • Did you clean up your area • Did you push in your chair • Do you have all your belongings

21. Homeroom • Planners out • I need your report cards • You need to be reading or studying • NO TALKING

22. Get your binder Copy this on new page! Weathering, Erosion, Deposition CRACK- Break WOOSH- Move PLOP- Drop All caused by wind, water or ice Be a Rock Weathering-Crack Erosion- Whoosh Deposition- Plop

23. WEATHERING EROSION

24. TIC TAC LAB

25. Write in your Binder the lab set up! TIC TAC LAB PROBLEM: Do bigger rocks or small sediment weather faster? HYPOTHESIS: I think that the bigger rocks will weather faster If I break the rock, instead of letting it dissolve.

26. Write in your spiral the lab set up! TIC TAC LAB Materials: Mouth, 2 tic tacs Variable: __________________

27. Write in your spiral the lab set up! TIC TAC LAB Steps: • Put a tic tac in your mouth, do not bite it • Lightly swish it with your “river” in your mouth • a. Think about your observations • Now swish it faster and hit your teeth (rocks)…do not break it • a. Think about your observations • Now bite it and swish it • a. Think about your observations • 5. Swallow and write your observations

28. Write in your spiral the lab set up! TIC TAC LAB Observations: __________________ Conclusion: Summarize the tic tac lab, explaining what the tic tac represents and the limitations of this model.

30. STOP Think before you leave. • Did you put binder on shelf • Do you have your planner out • Did you clean up your area • Did you push in your chair • Do you have all your belongings

31. Homeroom • Planners out • I need your report cards • You need to be reading or studying • NO TALKING

32. Binders out Copy on new page Changes to Earth’s Surface Changing Landforms

33. Landforms • Physical features on the Earth’s surface • These can be found on dry land or under water i.e. mountains, beaches, valleys, plateaus, rivers, etc.

34. Examples of Landforms

35. Landforms Change All the Time • Wind • Moving Water • Rain • Glaciers • Volcanic Eruptions • Earthquakes • Hurricanes

36. Weathering • Process of breaking down rock into smaller pieces, or sediments • Smoothes out rocks edges • 2 Types of Weathering • Physical Weathering • Chemical Weathering

37. Physical Weathering breaks up rocks without changing their composition Example- Rocks to sediment Chemical Weathering slowly changes the minerals that rocks are made up of. Example- Statue of Liberty Physical vs. Chemical Weathering

38. How does water effect weathering? • When water leaks into the cracks of rock and freezes the rock expands, then freezes • And what about glaciers?

39. Erosion • Process of moving sediment from one place to another

40. Deposition • Process of depositing sediment in a new location

41. 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

42. Changes to Earth’s Surface

43. Stream Table- Demonstration Let’s Discuss what happens in the model!

44. STOP Think before you leave. Homework is due tomorrow • Did you put binder on shelf • Do you have your planner out • Did you clean up your area • Did you push in your chair • Do you have all your belongings

45. Homeroom • Planners out • I need your report cards • You need to be reading or studying • NO TALKING

46. MS book out Red pen in hand Be sure to turn in so I can put the grades in

47. HOW LANDFORMS CHANGE SLOWLYQUICKLY WEATHERING MASS MOVEMENT Canyons mudslide landslide EROSION sinkholes glaciers avalanches Valley volcanoes earthquakes Deposition fires Beaches floods Deltas Oxbow lakes Islands

48. Stream Table- Demonstration Let’s look at this model, again!

49. What about Caves and Stalactites and Stalagmites
