Absolute Ages of Rocks
In this age of rocks worksheet, students answer five matching questions about terms related to the decay of atoms. They use a strip of paper to simulate half life of atoms and determine the total amount of time it took to deplete the paper.

Determining Absolute Age
How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Geologic Age
Learners investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.

Relative Aging Study Guide
In this relative age worksheet, students define relative time and absolute time and define the laws and rules of determining the age of rocks and fossils.
Curated OER
Geologic Age
Students investigate rocks. In this geologic age lesson, students conduct an experiment to determine absolute age as one would for rock layers. Students graph data and problem solve using results.

How Old Is Mike?
Students examine the absolute dating of fossils, they use a list of names and ages to determine the difference between relative age and absolute age. They explore the relative age and absolute age of people and of fossils.

Relative Aging Study Guide
In this relative aging activity, students define relative time and absolute time and define the laws and "rules" related to studying the age of fossils and rocks.

Examining the Fossil Record
Students create an evolutionary tree based on fossil morphology and their ages. In this fossil record lesson plan, students are given 23 pictures of fossil. They study their morphology and arrange the fossils by age and structures on a...

Measuring Absolute Time
In this absolute time worksheet, students answer eleven questions about ways to measure the age of fossils. They define half-life, answer questions about radioactive dating, tree rings and varves.

The Mystery of Earth’s History
Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Geologic Time: Relative and Absolute Dating
Young scholars investigate relative and absolute dating; determine the difference between the two dating systems; and apply this knowledge by creating a geologic timetable of their own.

Understanding the Geologic Timescale
Students identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...
