Learners 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...

High schoolers perform experiments in which they grow crystals. They draw pictures of where each type of rock originates from. They also identify igneous rocks by using a chart.

Ready to roll up those sleeves and get your hands dirty? Dirty with soil science content, that is! Overcome those "But it's just dirt" objections with a trip outside to collect soil samples for some in-class analysis. Use the...

Learners study minerals and their physical properties.  In this mineral lesson students use technology to investigate minerals and their properties. 

Students classify sediments based on their physical characteristics, such as size, shape and color. They identify and describe rocks and minerals that are common to their region of the state.

Explore a variety of science concepts in an interactive textbook created for middle school scholars. A lengthy table of contents takes readers to pages comprised of a subject overview, outline, and summary. Follow links further to find...

Students observe and describe the properties of rocks and their significance relationship in the environment. They explain the implications of destroying habitats and the importance of rebuilding them.

Students investigate rocks and minerals and take a field trip to sample soils. They analyze rocks and soil, research the geological terrenes of the topology of San Francisco, and produce a lab research report.

Students make a mold using Plaster of Paris and then make a cast using that same mold. They pick a fossil and describe how it looks. They write a fictionalized story about its life, or burial. (

In this geologist learning exercise, students identify and collect five geologic specimens that have important uses, giving an example of each. Also, they create a drawing that shows the cause of a volcano, a geyser, or an earthquake....

Want your class to rock? Then try this boulder activity. Pupils learn about a specific boulder field and use edible materials to demonstrate the geological processes that formed this unique feature. Weathering, erosion, and mass...

Eighth graders compare and contrast the three different types of rock. In this earth science lesson, 8th graders classify rock samples according to their correct rock type. They design their own data collection table.

Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...

In this geology lab activity, students answer 31 short answer questions about sedimentary rocks. Teacher needs to provide text or internet site for students to find answers.

Students explore the development of the geologic time scale. They examine the major time periods in earth's history. Students discuss the role fossils play in helping us understand history.

Students investigate how to use Moh's Hardness Scale. In this geology instructional activity, students examine several minerals and develop a hypothesis about which mineral is the hardest. Students use the Moh's Scale Identification...

In this geological time line worksheet, students compare the time lines they created of the earth's history to the history of Missouri. They answer questions about the eras, the scale of the time lines and the major events that occurred...

Students discover the relationships between minerals, crystals and gems. They bring in rocks that they find at home, in the schoolyard, etc. and examine them and attempt to identify them. They set up a classroom exhibit that includes all...

In this science worksheet, students review the vocabulary words for the separate categories related to the concept of geology.

Students investigate the rock cycle. In this geology lesson, students read about the rock cycle on a website and discuss the steps of the rock cycle. Students visit a rock cycle website to complete a quiz. This is the first introductory...

Students devise a rock word web and sort rocks by applying the categories they discuss.

In this earth science worksheet, students determine the name of 10 minerals based on the descriptions given on the page. They see pictures of a number of minerals, and check their answers with the word bank at the bottom of the page.

Students examine igneous and sedimentary rocks. They observe and identify geological formations in their community, analyze igneous and sedimentary geological layers using a geological map, and use GPS to locate geological formations.

Students investigate the physical and chemical characteristics of minerals. They make a list of the uses of minerals found in Illinois. They write a report individually based on their observations.
