This activity consists of 2 parts created by different entities. The simulation has instructions on the left side of the screen with a bar that can be scrolled forward as you proceed. The icons are interactive at the bottom of the page: a nail with a tag and a magnifying glass, the computer, a chisel and a specimen collection box. The dig site number is displayed at the top so students can keep track of which site they are using. The worksheet provides the background, procedure and data tables from each dig site organized in a way that the data can be easily transferred and analyzed. MS-ESS Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Clarification Statement: Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents including continental shelves , and the locations of ocean structures such as ridges, fracture zones, and trenches.
Comments about Including the Performance Expectation In the dig site simulation the students start immediately interpreting data and finding evidence on the distribution of fossils and rocks.
The worksheet has labeled data tables used to organize and interpret the findings of the dig site simulation. This activity does not address any continental shapes, seafloor structures or plate motions.

Only the distribution of fossils and rocks, the age of rock layers and the Law of Superposition are addressed in this activity. In addition to the simulation activity, to meet this part of the performance expectation I would have the students complete a kinesthetic lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions. In this activity students are given a map with a view of the Earth as a whole including the seafloor structures.
Students will create a model and explain it to their peers with their moveable continental plates. This resource is explicitly designed to build towards this science and engineering practice.
MS-ESS Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions. Clarification Statement: Examples of data include similarities of rock and fossil types on different continents, the shapes of the continents (including continental shelves), and the locations of ocean structures (such as.
Comments about Including the Science and Engineering Practice Using the data collected from each virtual dig site, students will analyze and predict ages of rock layers and come to their own conclusions about the Law of Superposition. This resource appears to be designed to build towards this disciplinary core idea, though the resource developer has not explicitly stated so.
Comments about Including the Disciplinary Core Idea The disciplinary core idea is illustrated by a simulation of a fossil dig and the fossils found in each site correlated to an age of the substrate this activity is clearly an investigation of rocks and fossils. By matching partial sequences, the truly oldest layers with fossils can be worked out.
By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. This is called relative dating.
Relative dating tells scientists if a rock layer is "older" or "younger" than another. This would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.
In reading earth history, these layers would be "read" from bottom to top or oldest to most recent.
If certain fossils are typically found only in a particular rock unit and are found in many places worldwide, they may be useful as index or guide fossils in determining the age of undated strata. By using this information from rock formations in various parts of the world and correlating the studies, scientists have been able to establish the geologic time scale.
This relative time scale divides the vast amount of earth history into various sections based on geological events sea encroachments, mountain-building, and depositional eventsand notable biological events appearance, relative abundance, or extinction of certain life forms. Objectives: When you complete this activity, you will be able to: 1 sequence information using items which overlap specific sets; 2 relate sequencing to the Law of Superposition; and 3 show how fossils can be used to give relative dates to rock layers.
Materials: two sets of sequence cards in random order set A : nonsense syllables; set B : sketches of fossilspencil, paper Procedure Set A: 1 Spread the cards with the nonsense syllables on the table and determine the correct sequence of the eight cards by comparing letters that are common to individual cards and, therefore, overlap.
SW Science 10 Unit 6 Relative Dating Worksheet Name: Student #: Geologic Time Relative Dating The Law of Superposition In any undisturbed sequence of strata, the oldest layer is at the bottom of the sequence, and the youngest layer is File Size: KB. fireemblemheroestips.com: File Size: 14 kb: File Type: docx: Download File. Powered by Create your own unique website with customizable templates. Once students begin to grasp "relative" dating, they can extend their knowledge of geologic time by exploring radiometric dating and developing a timeline of Earth's history. These major concepts are part of the Denver Earth Science Project's "Paleontology and .
The first card in the sequence has "Card 1, Set A" in the lower left-hand corner and represents the bottom of the sequence. If the letters "T" and "C" represent fossils in the oldest rock layer, they are the oldest fossils, or the first fossils formed in the past for this sequence of rock layers.
Now, look for a card that has either a "T" or "C" written on it. Since this card has a common letter with the first card, it must go on top of the "TC" card.
STEP Answer the question about fossils and relative time, then press "NEXT" Read through the screens, and answer the following question: WHY DOES RADIOMETRIC DATING WORK? STEP Read through the screens until you find the . Like, OMG! I totally love Science!

The fossils represented by the letters on this card are "younger" than the "T" or "C" fossils on the "TC" card which represents fossils in the oldest rock layer. Sequence the remaining cards by using the same process.
When you finish, you should have a vertical stack of cards with the top card representing the youngest fossils of this rock sequence and the "TC" card at the bottom of the stack representing the oldest fossils.
Interpretation Questions: 1 After you have arranged the cards in order, write your sequence of letters using each letter only once on a separate piece of paper.
