Wednesday 3/6/19 Turn in your Earthquake and Volcano Investigation Packet and CER Papers! Bell Ringer: How old are you? How old is Mr. Boyle? How old is the Earth? 5-10 min

What is Geologic Time?

How have scientists pieced together this calendar of Geologic Time? Fossils can tell us what has happened in the past IF we know how they form.

Fossils Investigation Essential Question: How and where do fossils form?  You will work through a series of models to uncover how fossils form and they types of places in which they form. 

Key Vocabulary in the Intro Organism – refers to anything that is or once was living.  People, animals, insects, plants, bacteria, etc.  Remains – any part of the organisms body that is remaining after death  Scavenger- any other organism that eats dead organisms they come upon.  Vultures, coyotes, wolves, etc.  Decompose – over time material from a once living organism will be recycled back into the soil, water and air. 

Let's start together Model 1 Number the boxes in the diagram to show the order in which they occurred.  What is the first step in fossil formation? Support your answer with evidence from the diagram. 

Fossil Investigation: You will be working with a partner on Model 1 and Model 2 in the fossils packet. Carefully read the information and directions. Answer in complete sentences. 2 minutes

Thursday 3/7/19 Bell Ringer: One day you are out hiking in the mountains. You notice some dinosaur footprints pressed into the rocks! Do you think these footprints are fossils? Why or why not?

Fossil Investigation Day 2 Directions Using the materials in your basket to complete Model 3 – if you are working in pairs you will have to share the playdoh with the other pair.  When finished with Model 3 return the materials to the basket as you found them. If the desk or the animal has playdoh on it please wipe off with paper towel.  Complete Model 4 Read, highlight and complete the last section. Homework: Read pages 104-107 in the Earth’s Surface book (new book with arch on the front)

New Book Earth’s Surface a.k.a the Arch book. We will go back to using the Earth Structure (Geode Book) in a few weeks. Write your first and last name along with your period number on the cover and on the spine. We will store these in notebook cupboard. Please put it on your class period shelf once it is labeled. The geode book will be stored in the next cupboard to the right.

Friday 3/7/19 Bell Ringer: The picture below shows Montana T. rex; one of the most complete skeletons ever found. This fossil was discovered near the Fort Peck Dam. Describe the process you think paleontologists used to get this fossil out of the ground? called Montana’s T. rex. Discovered near the Fort Peck Dam and one of the most complete T. rex skeletons ever found, Montana’s T. rex stands 12 feet tall and approximately 40 feet from nose to tail. It would have weighed almost seven tons as it walked the eastern regions of the state. The Tyrant Kings, featuring Montana’s T. rex presents the science and research of Tyrannosaurus rex in a very, very big way.

Typical Process of Fossil Formation

How do Paleontologists get fossils out of the rock? Paleontologists prepare to remove a Tyrannosaurus rex skull from a fossil dig site in northern Montana and transport it to the Burke Museum at the University of Washington.Dave DeMar/Burke Museum/UW

What is a fossil? Get out your new textbook. Using the glossary in your textbook, find the definition for the word fossil.  Analyze the textbook definition of fossil in comparison to the definition you created at the end of the investigation.
