1 Monday, September 24th Entry Task Write down 3 things that you think are important to know about fossils. Be as detailed as possible. Schedule: Fossils Notes Objective I can understand that Earth’s past is revealed in rocks and fossils Homework: 9.1 Quiz tomorrow Please have on desk: 9.1 RSG 9.1 Review Questions

2 Traces or remains of living things from long ago.Traces or remains of living things from long ago. There are 2 main types of fossils:There are 2 main types of fossils: 1.Original remains 2.Rock fossils

4 Fossils that are the actual bodies or body parts of organisms.Fossils that are the actual bodies or body parts of organisms. There are 3 modes of preservation:There are 3 modes of preservation: 1.Ice 2.Amber 3.Tar

5 Ice is one of the best preservers of the remains of prehistoric life.Ice is one of the best preservers of the remains of prehistoric life. Huge ice fields in Siberia and Alaska contain 10,000 year-old mammoths.Huge ice fields in Siberia and Alaska contain 10,000 year-old mammoths.

6 Amber forms from resin, a sticky substance inside trees that flows like syrup and protects the tree by trapping insects.Amber forms from resin, a sticky substance inside trees that flows like syrup and protects the tree by trapping insects.

7 Original remains of animals have also been found in places where there are pools of tar – a thick, oily substance.Original remains of animals have also been found in places where there are pools of tar – a thick, oily substance.

9 If an organism is covered by or buried in sediment, it may become a fossil as the sediments become rock.If an organism is covered by or buried in sediment, it may become a fossil as the sediments become rock. There are 4 main types of fossils that we find in rocks: molds and casts, petrified wood, carbon films and trace fossilsThere are 4 main types of fossils that we find in rocks: molds and casts, petrified wood, carbon films and trace fossils

10 A mold is a visible shape that has left after an animal or plant was buried in sediment and then decayed away.A mold is a visible shape that has left after an animal or plant was buried in sediment and then decayed away. A cast fossil is a solid model in the shape of the organism.A cast fossil is a solid model in the shape of the organism.

11 The stone fossil of a tree is called petrified wood.The stone fossil of a tree is called petrified wood.

12 Carbon is an element that is found in every living thing.Carbon is an element that is found in every living thing. Sometimes when a dead plant or animal decays, its carbon is left behind as a visible layer.Sometimes when a dead plant or animal decays, its carbon is left behind as a visible layer.

13 Trace fossils are not parts of an animal or impressions of it, but rather evidence of an animal’s presence in a given location.Trace fossils are not parts of an animal or impressions of it, but rather evidence of an animal’s presence in a given location. Trace fossils include: footprints, trails, animal holes, and even feces.Trace fossils include: footprints, trails, animal holes, and even feces.

15 Conditions have to be just right for a fossil to form in rock – the organism must be preserved before it decomposes or disappears.Conditions have to be just right for a fossil to form in rock – the organism must be preserved before it decomposes or disappears. Rock fossils form in sedimentary rock. Why not in igneous rocks?Rock fossils form in sedimentary rock. Why not in igneous rocks?

16 Tuesday, September 25 th Entry Task Match the evidence with what scientists can learn about it. Write it all out. Type of Evidence 1.Tree rings 2.Trace fossils 3.Mold fossils 4.Petrified wood What can be learned a.Ancient trees b.Soft organisms c.Footprints d.Recent weather patterns Schedule: Bill Nye Fossils 9.1 Quiz Homework: None Objective: I can explain important information about fossils Please have on desk: Fossil Foldable

17 Wednesday, September 26 th Entry Task Make sure you have a book on your desk. Today we will be reading 2 sections and doing 2 RSGs. Whatever you do not finish in class will be homework. Schedule: Read/RSG 9.2 Homework: Finish Reading/RSG 9.2 Read/RSG 9.3 Objective: I can understand that Rocks provide a timeline for Earth and that the geologic time scale shows Earth’s past

18 Thursday, September 27 th Entry Task Imagine that a new road is being built in your area. Some hillside has been cut away, leaving its rock layers exposed. Draw a diagram of the rock layers. Label the layers from youngest to oldest. Schedule: Geologic Time Scale Homework: Chapter 9 Vocabulary Objective: I can understand how the geologic timescale can show clues to Earth’s past Please have on your desk 9.2 RSG 9.3 RSG

19 Chapter 9 Vocabulary There are 9 vocab words for chapter 9. You can find them on page 312. Pick a vocabulary strategy to do for all 9 of these. You can find the strategies in the back of your text book on page R50. Do these in your notebook in the next blank spot

20 Friday, September 28 th Entry Task Answer the following questions full sentences, IQIA. 1.Describe the concept of uniformitarianism 2.What does the geologic time scale measure? 3.What was life like on Earth for most of its history? Schedule: Geologic Time Scale Homework Questions 1-6 page 301 Use full sentences, IQIA Objective: I can understand how the geologic timescale can show clues to Earth’s past Please have on desk: Chapter 9 Vocabulary
