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


Fossils are found in sedimentary rock

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


Let s make a fossil

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


Homeroom

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

How do fossils help us to learn more?


Homeroom

Thinking like a paleontologist


How do you know

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?


Let s try again

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

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 paleontologist1

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?


Homeroom

“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

Once Upon a Time

Asian Elephant

Wooly Mammoth

How are these two animals the same?

How are they different?

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.


Why does that matter

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.


Homeroom

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

TIC TAC LAB


Homeroom

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.


Homeroom

Write in your spiral the lab set up!

TIC TAC LAB

Materials:

Mouth, 2 tic tacs

Variable:

Homeroom

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

Conclusion:

Summarize the tic tac lab, explaining what the tic tac represents and the limitations of this model.

Changes to Earth’s Surface

Changing Landforms


Landforms

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

Examples of Landforms


Landforms change all the time

Landforms Change All the Time

  • Wind

  • Moving Water

  • Rain

  • Glaciers

  • Volcanic Eruptions

  • Earthquakes

  • Hurricanes


Weathering

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

Physical vs. Chemical Weathering


How does water effect weathering

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

Erosion

  • Process of moving sediment from one place to another


Deposition

Deposition

  • Process of depositing sediment in a new location


What new landforms are created by erosion and deposition

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
