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...

In this dinosaurs worksheet, students review the different theories that scientist believe may have led to the extinction of the dinosaurs. This worksheet has 18 fill in the blank questions.

In this earthquakes and volcanoes activity, students will review how volcanoes are formed and where they are found. Students will describe earthquakes and their magnitudes. Students will use a table to answer questions about tsunamis....

In this evolution worksheet, high schoolers will complete a table by writing in the era and biological event based on 4 different time periods of Earth's history. Students will answer 8 fill in the blank questions based on the different...

In this gravity worksheet, 8th graders complete 4 different questions related to defining gravity. First, they identify the various types of mass movement that is described in each. Then, students explain what each of the 4 types of...

In this moving continents activity, learners review the different types of plate boundaries, what causes earthquakes, and where volcanoes are formed. This activity has 10 fill in the blank and 9 short answer questions.

Using a cake analogy, this activity teaches concepts such as: geologic time, rock layers, fossils, Law of Superposition, and relative dating. Activity can be modified to grade level and appropriate content for learners,

[Free Registration/Login may be required to access all resource tools.] Looks at how stratigraphy can be used to determine the relative ages of rocks, how unconformities occur, ways to match rock layers in different areas, and how...

An explanation of radiometric or absolute dating of geological formations based on using the half-life of radioactive elements to figure out how old given rock layers are. A link on the left provides information about relative dating as...

This lesson involves an innovative strategy for introducing the concept of relative dating using a block of wood that has been painted, damaged, and nailed. The task for young scholars is to analyze the order in which these events...

[Free Registration/Login Required] This flipchart presents information about how the earth was formed. It discusses methods of dating the layers of the earth's surface. Assessment questions are included.

In this interactive tutorial you will explore how geologists use clues in rocks to determine the order in which rocks formed. Learn how principles of radioactivity are used to assign actual ages to rocks. Students will explore fossils...

In this activity, students use popcorn to simulate the process scientists use to date layers in an ice core.

[Free Registration/Login may be required to access all resource tools.] How rock layers in different locations can be connected to make pictures of a region's geology.

Arrange fossil pictures in sequence from oldest to youngest.

Understand fossils and the fossil record as it relates to Earth's history.

A discussion of geologic time, how scientists use the concept, and how they have determined its span.
