Radiometric dating activity answers
They will only re shake the radioactive M&Ms each time. Once they are finished with their 8 runs, they will record their data on the class data table (which can be on the board).Once all groups data is on the table, you can calculate the average for each run (1-8) and determine a class average.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 Dinosaurs" module written for students in grades 7-10.
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
The module is an integrated unit which addresses the following National Science Education Standards: *Science as Inquiry: Students develop the abilities necessary to do scientific inquiry identify questions, design and conduct scientific investigations, use appropriate tools and technologies to gather, analyze and interpret data, think critically and logically to make the relationships between evidence and explanations, communicate results, and use mathematics in all aspects of scientific inquiry.
*Life Science: Fossils indicate that many organisms that lived long ago are extinct.
Although most attention in today's world focuses on dinosaurs and why they became extinct, the world of paleontology includes many other interesting organisms which tell us about Earth's past history.
The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.
