Capacitor Lab.Use the theory of radioactive isotope decay to calculate parent and daughter isotope abundances and determine the absolute age of geological materials. Determine relative geologic age sequences using the basic principles of relative age determination.

Distinguish different types of unconformities in the stratigraphy of the Grand Canyon. There are two parts to this lab exercise A. Part 1 is on absolute age determinations using radioactive isotopes and their daughter products in geological materials. In Part 2 you will use the principles of relative dating to determine sequences of geological events as indicated by the layers and structures in the rocks.

Part 2 ends with an application of the principles of relative dating to the rocks of the Grand Canyon. E-mail a copy of your certificate to the Assignments folder in the virtual classroom, or else mail in a hard copy, or both.

Note on Carbon Table 8. Add one more: Carbon decays to Nitrogen with a half-life of 5, years. With such a geologically short half life, carbon can only be used to determine ages of relatively young materials, less than 70, years old.

Older materials have so little carbon left that it cannot be accurately measured. Thus, carbon is of no use in determining the absolute ages of, for example, dinosaur fossils. The only materials that start out with usable amounts of carbon in them are carbon-bearing materials which derived their carbon immediately from the atmosphere or from shallow water.

This means that the remains of living things are useful for carbon dating. Most rocks, however, are not useful for carbon dating either not enough carbon, or didn't derive its carbon from the atmosphere-shallow water reservoir. You can either print out and mail a copy of your marked-up exercise Part A from Dr.

Reynolds, to:. Remember to put your name on your exercise pages, not just the outside of the envelope. View the above image, a cross-section side-view of a cut-out through the crust of the Grand Canyon. Study this diagram carefully, noting the orientation of individual rock layers, as well as the type of rock in each layer, and the age of the rock in each layer.

Refer to the geologic time scale on page for the names of each of the geologic time periods, as well as the absolute dates attached to each Period. In order to answer the following questions, you will need additional geologic information about the Grand Canyon. Four major unconformities are evident in the Grand Canyon cross-section. Remember that unconformities represent sections of missing time, either through non-deposition of rocks for a period of time, or through an interval of erosion which has removed some strata.

Strata are layers of rock. The three different types of unconformities are shown in the textbook refer to the index of the book to find where. Each of the four major unconformities in the Grand Canyon can be identified as one of the three specific types of unconformities.

For each of the four major unconformities in the Grand Canyon, answer each of the following questions:. Between which two rock layers use the names of the rock layers shown on the diagram does the unconformity occur? What evidence do you specifically see that allowed you to identify an unconformity at this location?As many us work on developing online courses we have to ask ourselves how to implement lab activities.

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.

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.

This activity does not address any water patterns in each of the simulated dig sites and the ancient land would relate loosely to the layers in the simulated dig site.

Only the age of the rock layers and the Law of Superposition are addressed in this activity. After this simulation have the students complete a lesson related what they have learned about the ages of the rocks and fossils, but adding in plate motions.

This resource is explicitly designed to build towards this crosscutting concept.

Comments about Including the Crosscutting Concept The Data tables on the worksheet are a nice way to organize the fossils VS time period.

The data shows a numerical relationship to the age of the rocks. Another numerical relationship is having the students use a method called radiometric dating to calculate the absolute age of the rock. Reviews No reviews Be the first to write a review. Performance Expectations.

Guide to Evo Conceptual framework Teaching resource database Image library Dealing with objections to evolution Correcting misconceptions Alignment with science standards.The lab is one in which students get to work together to figure out some geologic "puzzles".

Correlating rock layers involves using techniques like index fossil correlation, superposition, and horizontal originality to piece together what happened in the past. Students are tasked with three "mini-labs" in this class block, which are of increasing complexity.

Relative Dating - Example 2

We read the information collectively, with particular emphasis on the definition of what constitutes an index fossiland the criteria that make it one 1. I then briefly explain the multi-part nature of the lab note Procedure s ABand C below, which are done in order and then have students transition quickly into their lab groups. Like always, students are timed during this transition, and any "records" are kept celebrated and publicized on the display board at the front of the room.

Procedure A presents students with their first and easiest problem of the day. There are no index fossils here yetas I want to get them familiar and comfortable with the process of geologic correlation first. They are to use the four 4 disparate rock layers A, B, C, and D and use their knowledge to make one geologic sequence on the next page underneath the term Procedure A.

As I've noted many times before, pedagogically, I structure this more or less to the needs of the class. For one of my classes, which struggles a bit more and tends to reach frustration level a bit easier, I try to model at least the first part of this with them so that they have a bit more guidance going into to the rest of this section, and Procedures B and C later on in the class period.

For my more advanced students, I might offer no more than a hint or suggestion on how to proceed before letting them grapple with it. As a general note, feel free to consult the embedded comments for a complete key on the correct version of rock strata, but it is most helpful to start from the bottom farthest in the geologic past and work your way to the present.

How to calculate air flow rate from pressure and diameter

Some rock strata A,B,C,D are missing rock layers due to erosion or creation of unconformities. That's okay! Students might be worried at first about this. Due to geologic and tectonic forces, sometimes rock strata aren't found where they should be, and that's fine!

That eliminates a lot of potential confusion and helps clarify for students where to look next. Generally, I find that this doesn't take them too long, especially once they understand the concept of using the illustrated geologic evidence to date the index fossils. When lab groups are struggling with this problem, I find that they only need a gentle push to refer to the notes on the index fossils to successfully complete the correlation.

But the procedure for students is basically the same - they're allowed to proceed together to communally work out the problems together.

As noted above, students have the opportunity in this lab to pace their own work. Aside from group check-ins, the lab groups can work at their own pace through the listed procedures. Given that there are no necessary materials needed for this lab outside of the normal printed resources, clean up is usually quick, and only involves having the students put their desks back into a normal classroom arrangement and preparing their desks for transitioning out of the room.

In the last minute or so, I do utilize the same procedure I do on non-lab days, which is to ask the students time to think about their self-mastery of the objective which is posted on the whiteboardthrough some guided questions:.
