Fossils of hard mineral parts like bones and teeth were formed as follows: Some animals were quickly buried after their death by sinking in mud, being buried in a sand storm, etc. Over time, more and more sediment covered the remains. The parts of the animals that didn’t rot usually the harder parts likes bones and teeth were encased in the newly-formed sediment.
In the right circumstances no scavengers, quick burial, not much weathering , parts of the animal turned into fossils over time. After a long time, the chemicals in the buried animals’ bodies underwent a series of changes.

Parents Information This lesson plan is designed so that your child can complete the chapter in five days. Since there is no research topic in this lesson, no parental decisions need to be made. The grade for this chapter can come solely from the end of chapter test. Geologic Time Geologists interpret the rocks of the earth based on their past history. Prior to the late ‘s, the accepted method of belief in earth’s history was based on a concept called catastrophism.
Catastrophism says that the earth is very young, about 6, to 10, years old. It also states that what we see in the rock record is the result of many catastrophic events that were quick in duration, such as volcanic events, or in the case of young earth creationism, the year-long global flood. In the late ‘s, the first geologists started to question this interpretation. They saw evidence in the fossil record that indicated the earth’s features evolved over many millennia, from slow and gradual processes.

Relative Dating Worksheet. 1. How does the rock layer H compare to rock layer M? Why? 2. How come the rock layers on the left side of the picture do. Name Date Class. The Relative Age of Rocks. Write the letter of the correct answer on the line at the left. L; .
General Lesson Plan Learning Objectives: What should students know and be able to do as a result of this lesson? Students will be able to define the Law of Superposition. Students will be able to organize fossils by their relative ages using the Law of Superposition. What prior knowledge should students have for this lesson? Students should have mastered 4th grade standard SC.
Identify the three categories of rocks: Students should already know that sedimentary rocks can be found in layers. Students should also know what a fossil is and that paleontologists search for them in order to give us clues about Earth’s past. What are the guiding questions for this lesson?

Rock Cycle Cartoon – Day 2 50 minutes Making students’ thoughts visible through pictures As we begin the second day of this lesson, I ask students to bring out the data they gathered the day before as they traveled through the rock cycle. I tell the students that they will have the rest of the period to work on the cartoon. I also mention that I do not expect them to finish in one class period, so any portion that is not finished will have to be done outside of class time.
They are expected to turn in their finished products in three days. I provide students with blank paper and coloring materials and allow them to get to work. I decided to provide only one class period for the students to begin their cartoons and have them finish for homework because I want them to have enough time to turn in quality work. There are always students that take a long time to draw out their ideas. This makes it so that I have a group that is done right away and one that will benefit from more time.
By starting in class and finishing at home, all students have the time they need to get it done without anyone having to wait. The conceptual load is not huge, and the students do not need my support to draw, so I’d rather they use their own time to complete this assignment and allow us to move on to the next lesson. In this video you can see samples of the students’ work.
Rock cycle cartoon instructions and rubric Rock Cycle Cartoons Closure 5 minutes To bring this lesson to a close, I have students go back to the Rock Cycle probe they completed at the on Day 1, and either correct their initial answer if they now have a different answer or confirm their original answer citing evidence from this lesson.
I collect the “corrected” probes and as I go over them, I am looking for answers that still reveal a misconception, and make sure that I address it with the individual students during the next session. All students had correctly identified the character that provided the “right answer”, and given sufficient evidence as to make going back to the probe unnecessary.

The half-life of a radioisotope can be used to measure the age of things. The method is called radiodating. Radiodating can be used to measure the age of rocks see below and carbon dating can be used to date archaeological specimens. Using Uranium to Date Rock. Some rocks contain uranium which is radioactive and follows a decay series until it produces a stable isotope of lead. The amount of uranium in the rock is compared to the amount of lead and then the age of the rock can be calculated.

Put together a survival guide for your region. Consider the different types of shelters where prehistoric people lived. Is it a cave, canyon overhang or alcove, or a rudely constructed tent or hut? What types of terrain did they frequent? Is it a woodland, a valley, hill country? Now create a model or diorama of an imagined prehistoric dwelling. How were these people alike and how did they differ. Present your findings in a graphical way by creating a poster that identifies your findings.
A single watch or clock for the entire class will do. Return to top PART 1: After students have decided how to establish the relative age of each rock unit, they should list them under the block, from most recent at the top of the list to oldest at the bottom. The teacher should tell the students that there are two basic principles used by geologists to determine the sequence of ages of rocks.
Younger sedimentary rocks are deposited on top of older sedimentary rocks.

After that comes a more difficult process: Finding a fossil merely places one organism within a time span. Finding many organisms places the group within a time span. Determining the actual existence-span of the species is very approximate. If the fossils are relatively rare, the actual existence-span may be much greater that the fossil record indicates. Even if the fossils are relatively abundant during the species’ heyday, the number of organisms may have been small during the time of its appearance on Earth and during its demise.
At these important times, its fossil record might be sparse or nil, causing those times to be under-represented. The oldest method is stratigraphy, studying how deeply a fossil is buried. Dinosaur fossils are usually found in sedimentary rock. Sedimentary rock layers strata are formed episodically as earth is deposited horizontally over time. Newer layers are formed on top of older layers, pressurizing them into rocks.
Paleontologists can estimate the amount of time that has passed since the stratum containing the fossil was formed.

USING RELATIVE DATING AND UNCONFORMITIES TO DETERMINE SEQUENCES OF EVENTS Introduction In order to interpret Earth history from rock layers, it is necessary to know which rock layers are older and which rock layers are younger. Absolute .
