Modeling Nuclear Decay

Resource:
Modeling Nuclear Decay

In this actitivity, students learn about radioactive dating by modeling radioactive and decayed carbon atoms with the heads and tails side of pennies.

Unit 4 Absolute Dating 5E Instructional Model Plan

In this 5E sequence students model nuclear decay by emptying a bag of one hundred pennies on a table and removing all the pennies that are on the tails side (or that have decayed). Students repeat this process with remaining non-decayed pennies several times and record the data. Then students make connections to a radiometric dating and calculate the age of several objects using nuclear decay data. Finally, students elaborate on their learning so far in the unit by completing a 3-level guide that supports them in reading and interpreting the Geologic Time Scale found in the Earth Science Reference Table.

Unit 4 Does this Fossil Exist in New York State? Performance Task

Resource:
Unit 4 Does this Fossil Exist in New York State? Performance Task

Your challenge is to determine what your fossil is, how old the fossil is, and if the fossil could be found within the bedrock of New York State. You will organize your data about the fossil with the aid of a variety of questions. Based on the data provided and your Earth Science Reference Table, write a scientific explanation using evidence determining if your fossil could have existed in New York State.

Unit 4 Geologic History & Evolution of Life Unit Plan

The Earth's geologic history tells a story about the inception of life and the rise and fall of species, showing life is fragile in the face of gradual and sudden changes to the environment. In this unit, students will learn how rock and fossil observations in combination with radioactive dating techniques have been used to construct a geologic time scale.

Unit 4 Stratigraphy 5E Instructional Model Plan

In this 5E sequence students create their own models of sedimentary rock layers using various mixtures of sediment, then model folding and faulting in rock layers using clay. Students use the experience of modeling rock layers to develop an understanding of basic geologic principles. Their thinking is then extended by engaging in an activity in which they correlate rock layers based on composition and fossil evidence.
