How Old Is Mike?
Young scholars 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 Ages of Rocks
In this ages of rock worksheet, learners will review the processes and techniques of determine the age of rocks. Then students will use a rock layer diagram to determine what rock materials are older or younger. This worksheet has 16...

Relative Dating-Telling Time Using Fossils
Students explore how to read fossil range charts. They develop an knowledge of the strengths and weaknesses of the fossil record. Students become familiar with the concepts index fossil and fossil range. Students use bar graphs to...
Curated OER
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.

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...

Determining the Age of Fossils
High schoolers examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.
Curated OER
Relative Dating - Telling Time Using Fossils
Students use fossil range charts to explain relative dating. They graph for ammonites, marine organisms that went extinct at the same time as dinosaurs.
Curated OER
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...
Curated OER
Determining Age Of Rocks And Fossils
Students discuss together how to determine the relative age of each of the rock units in the block diagram (Figure 1). After students have decided how to establish the relative age of each rock unit, they should list them under the block.

Dating Sedimentary Strata
Students investigate how the age of sedimentary strata is determined. For this sedimentary strata lesson, students work through problems that show that geological history covers millions of years. They distinguish between relative and...
Curated OER
Geologic Time: Relative and Absolute Dating
Students 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.
Curated OER
Absolute Ages of Rocks
In this rocks worksheet, students review the process of absolute dating of rocks and compare it to the relative dating process. This worksheet has 16 fill in the blank questions.

VARVES: Dating Sedimentary Strata: Geology, Paleontological Patterns
Students count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.

A Discourse on the History of Language
Analyze and make inferences from the information used by linguists to construct the evolution of languages. They research different dating techniques to explain how scientists infer age with evidence.

Your Nutrition Needs
It takes some work to ensure you have a balanced diet, but once you know the types of foods that are good for you, it becomes second nature. In the sixth of seven lessons about energy and nutrition, learners create a healthy eating plan...
