Advanced students may be able to learn from this information. If this rock formed less than 2 million years ago, then it is impossible that it was crafted by an Australopithecus!. The video is a great review tool. Inform your students that you have heard back from the Natural History Foundation. Collect student essays and review responses as a class. They know that the rock used to be entirely made of Uranium-235. The only error that might occur is a careless mistake where the wrong atomic number or mass number was written down in a decay equation.

For the next 5 minutes, after checking in the homework, I go over the decay series and graph that was to be completed for homework. Students must complete mathematical calculations involving equations and operations with fractions and percentages. If you feel these questions may benefit your class, you could either speak about them with each of your groups separately, or provide each group with this list of questions to help them with their response essay. The Pleistocene goes from 11,700-2. They can then complete calculations to see how many half-lives have passed, which will tell them the age of the rock! Please write us back and tell us which elemental isotope you feel should be used to calculate the age of each of our three specimens. This strategy is very easy to implement and requires very little time. Yes And how many half-lives had to pass to get us to 50g? Is that how much the scientist found in the rock? This part of the simulation applies a real world application to the Crosscutting Concept, energy and matter, by showing them that energy is released during a chain reaction and can be controlled by the absorption of neutrons.

For the students that are still struggling I provide them with another practice decay series with one-on-one help to move them past their difficulties. Open discussion with the entire class. This strategy is a structured way for students to scaffold reflections to key learning points. Most of the trees in the park are from the Triassic Era. One of the main requirements of this lesson is the development of an essay. I recommend they should only spend a few minutes on the first part of the investigation, but make as many observations as possible about what they see.

This work is the culmination of many progressions of learning in arithmetic, problem solving and mathematical practices. Requirements for the essay are described specifically in the Instructional Suggestions section above. The three items that must be dated are as follows: 1. Many students struggle with graphing, so I allow them to take a picture of the decay series and graph in order to check for accuracy in a more efficient manner outside of class. T his lesson has my students model the process of fission, explain the byproducts of fission, explain how a chain reaction works, and describe the requirements for a chain reaction. By this point in the unit students have had enough practice working on alpha and beta decay problems that most do not have questions.

In the second part of the lesson, the data remains the same and is instead used to analyze two new items. If you do not have access to these, a class discussion, read aloud from an appropriate selection of text , or other video review would be appropriate. Please explain why you selected that particular elemental isotope for each specimen with clear and concise reasoning. The following questions are about each of the three items being dated. The half-life of U-235 is 700 million years.

Complete the BrainPop post-lesson quiz as a class. What item do they think would be the oldest? The video or activity video are both excellent introductory sources. The two items that must be dated are as follows: 1. Homework Review 7 After checking in the homework, I have the first page of the showing on the document cam. As they were taking the quiz I handed out the assignment.

Pass out the and sheets to each group. We are writing to request your assistance in determining the most effective dating technique to be used to calculate the age of three very rare objects that the museum has recently acquired. Use their responses to transition into the next section. Obsidian is a special type of igneous rock that can have very sharp edges. This rock may provide proof of an ancient sea that once covered the middle of the continent. The National Museum of Natural History was so pleased with the results that they asked us to date two of the most precious items they have in their collection! They should have a written explanation of the steps used to make this selection.

This process will help students develop an understanding that energy is released during fission. Begin class with a review of Radioactive Dating and Half-Life. However, if it is older, this discovery could open an exciting new chapter in the history of human tool use! If using block scheduling, this allows you approximately 1 hour of the same class day to review concepts with the class, do reading on related topics, watch an educational video, or any other desired lesson reinforcement. We are currently working with the National Museum of Natural History on a few of their most recent findings. Use the readiness questions to be sure each group understands the assignment. Which one would be hardest to date? Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.
