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 MS book now on the floor Get out your binder- open up to FOSSIL EVIDENCE

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 Lot’s of time What are you going to get A 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 Lot’s of time What are you going to get A FOSSIL! Write this in binder

Let’s make a fossil Using cereal and gummies we are going to make a sedimentary rock model 1.Anti- Bacterial your hands 2.Look in the microscope at the detail of the fossil 3.Get a cup 4.Add a layer of “sediment” 5.Add 1 “dead organism” 6.Add a layer of “sediment” 7.Add 1 “dead organism” 8.Continue until layers are complete 9.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

Would the bear on the left live in this warm environment? ….Or, would the bear on the left live in this colder environment? How do you know? First… Look at the bear in this picture. What environment do you predict it lives in? How did you decide which environment the bear lives in?

Look at these pictures of things that come from a tree. Make a prediction about the environment where you would find this tree. Would the tree live in this environment? … or, would the tree live in this environment? Let’s Try Again This is more difficult isn’t it? Why? What would help you decide on the correct environment?

Now you are the paleontologist 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? This is the environment where you are looking for fossils.

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

Once Upon a Time Wooly Mammoth Asian Elephant How are these two animals the same? How are they different?

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

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

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

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. Wrap-Up

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.

STOP Think before you leave. 1.Did you put binder on shelf 2.Do you have your planner out 3.Did you clean up your area 4.Did you push in your chair 5.Do you have all your belongings Do not throw away your cup Stack them and I will wash them Do not throw away your cup Stack them and I will wash them

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

WEATHERING EROSION WEATHERING EROSION

Write in your Binder the lab set up! 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. __________________

Changes to Earth’s Surface Changing Landforms Copy on new page

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.

Examples of Landforms

Landforms Change All the Time  Wind  Moving Water  Rain  Glaciers  Volcanic Eruptions  Earthquakes  Hurricanes

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

Physical vs. Chemical Weathering  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

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
