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

Let’s make a fossil• Using cereal and gummies we are going to make a sedimentary rock

model

1. Anti- Bacterial your hands2. Look in the microscope at the detail of the fossil3. Get a cup4. 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 complete9. 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 paleontologistThinking 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?

http://www.arctic.noaa.gov/gallery.html

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?

http://www.nps.gov/olym/wic/gallery.htm

http://www.nps.gov/yell/slidefile/index.htm

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

Note how the distance of the wrist bones from the ground changes. What else has changed?

• 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 futureHelps us understand why our world is like it is.

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 fasterIf I break the rock, instead of letting it dissolve.

Write in your spiral the lab set up!

Mouth, 2 tic tacs

__________________


1. Put a tic tac in your mouth, do not bite it2. Lightly swish it with your “river” in your mouth

a. Think about your observations3. Now swish it faster and hit your teeth (rocks)…

do not break ita. Think about your observations

4. Now bite it and swish ita. Think about your observations

5. Swallow and write your observations


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 WaterRainGlaciersVolcanic Eruptions EarthquakesHurricanes

Weathering

Process of breaking down rock into smaller pieces, or sediments

Smoothes out rocks edges2 Types of Weathering Physical WeatheringChemical 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
