Students view Understanding Geologic Time on the Internet or by CD-Rom to explore the length of time that the Earth has existed.

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

Practicing paleontologists map the geologic time scale, simulate the formation of sedimentary rock, and analyze fossil data. Instructions for four activities and five assessment choices are provided for the teacher. This comprehensive...

Students design, construct and interpret a model of geologic time and investigate change through geologic time.

Students recreate and comprehend the geologic time scale. They discuss how long humans have been around on Earth. Students are shown the geologic time scale and its different parts. They work in groups to recreate the time scale.

Learners investigate the history of Earth by creating a geologic time scale.  In this Earth History lesson plan, students practice sequencing events in their life as a way to get familiar with creating a time scale.  Learners...

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...

Learners create a simple tool to visualize geologic time. They create knots to represent the K/T, P/T and Precambrian boundaries in a 4.6 meter string with each millimeter representing one million years. They then refer back to this...

Third graders investigate the events of geological time using a chart called a "Clock of Eras". In this geological events lesson plan, 3rd graders compare a standard clock to a geological clock. In addition, students consider periods...

Students discuss information relating to Illinois geology. They examine top mineral resources in Illinois to find detailed information about geodes and where they can be found. Students complete geode lab to explore external structure of...

A beautiful tapestry map of North America is examined by geology masters. The map incorporates the topography and geology of different regions. You can purchase printed copies or a large poster of the map, or if you have a computer lab...

Young scholars study geology and explore the meaning of geological time.  In this geology lesson plan students use the Internet to find a website and answer the questions and fill out their handout. 

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Sedimentary rocks are the building blocks of this geology lesson. In it, learners discover what sedimentary rocks are and how they form. They understand the differences between the major sedimentary rock varieties and learn what types of...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson, learners use scientific equipment to collect...

Here is a geology lesson that is sure to get your charges excited. It's all about the process of weathering of rocks. Learners study natural events that can cause rocks to break apart. Some of these events are: ice wedging, plant...

After five class sessions, young scientists will be able to identify common rock types: igneous, sedimentary, and metamorphic. This plan involves hands-on activities, includes various handouts and worksheets, and requires there to be...

Students combine information from several field labs to construct an overall geologic history of the local region. They are able to use published reports of the geologic history as they compile their own version.

Students examine fossils to understand how they are formed and how they give information about geological history. In this fossil lesson, students research and write about fossils and make models of different fossil types.The PDF...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Students investigae using radioactive decay to determine geologic age.

Fourth graders observe and identify the effects of geological activities and weathering on Earth's surface. They also take a look at reports of events such as storms, earthquakes, floods, and volcanoes. There is a hefty hands-on activity...

Students investigate how geologic sequestration reduces carbon dioxide concentration in the atmosphere. In this earth science lesson, students simulate oil mining in the lab. They write down their observations and complete the lab report...

Students predict how sediments in a water column will settle.  In this earth science lesson, students examine the layers of sedimentation. Students are given sediments to place into a column of water and observe how they settle....
