Students investigate rocks. In this earth science instructional activity, students collect rocks from the schoolyard and describe each of the rocks. Students measure and weigh each rock and record the results. Students create a rock...

Fourth graders participate in a Rock Cycle game to gain an understanding of the cycles that form metamorphic, sedimentary and igneous rocks.

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

Using a jigsaw approach, earth science experts teach each other about the physical, biological, and geologic components of the carbon cycle, with a specific focus on the ocean. 

Students describe the water cycle and create a Mobius strip model. They determine that the weathering of rocks continually adds sodium to the Earth's rivers and subsequently to the oceans. They discuss the fact that the water on Earth...

Ninth graders explore ways water moves through various reservoirs on Earth, examine how human activities change water cycle, investigate substances present in water that indicate human activity, and discuss how understanding water cycle...

Third graders describe and label the water cycle, and list how water changes from one form to another; students use Inspiration Software to label a blank water cycle diagram.

Students explore the differences in sedimentary, metamorphic, and igneous rocks. They discuss the rock cycle of the different formations. Students discuss how rock is formed into different shapes. They explore, predict, and create each...

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Students explore the carbon cycle. In this carbon cycle lesson, students discuss the four main reservoirs where carbon is stored and then discover the process through which each reservoir absorbs and releases CO2. This lesson includes a...

How is the Earth's weather created? Middle schoolers will explain how the Sun's energy is transformed into different forms. They will perform mathematical calculations of volume, mass, and temperature. They they will explain the...

A hands-on activity helps learners explore the water cycle. After discussing how they use water, classes discuss water pollution and then move into a simulation where 20 pupils move through the water cycle based on description cards. 

The carbon cycle is natural and has happened for millions of years, so can humans change it? Young scientists play the role of carbon as they travel through the carbon cycle. They complete two rounds, once before the industrial...

Second graders discuss the geologic rock cycle and work with their group to simulate creating a sedimentary rock. They conduct an experiment that demonstrates the sedimentary process and draw the steps of the rock cycle.

Fifth graders observe several examples of types of rock and write about their similarities and differences in their science journals. They discuss their observations and discover that rocks are grouped according to the scientific...

Middle schoolers examine how sedimentary rocks are formed.  In this rock lesson students research different rock formations and different types of rock. 

Students investigate the property of rocks and how to distinguish among the different types. They explore the hardness of rocks and perform streak tests to determine mineral color. They classify rocks according to their properties.

Learners investigate how the ocean plays a part in the water cycle. In this earth science instructional activity, students locate a puddle outside and mark it with chalk. Learners observe the changes in the water during the next two days.

Pupils explore, predict, and create each major rock form (sedimentary, metamorphic, and igneous) with colored modeling clay, discover cycle of rock formation, and examine important relationships of heat and pressure in rock development.

Students explain the processes involved in the rock cycle. In this earth science instructional activity, students identify the different kinds of rocks. They complete a worksheet during the activity.

Third graders study the 3 main types of rocks: igneous, sedimentary, metamorphic. They examine samples of these types of rocks and discuss ways to tell what kind of rock each is. They take notes and draw pictures in their science...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

Students examine a crushed rock and sort the minerals they find in that rock by color and other properties.

Students explore the physical properties of rocks. They explore the three different types of rocks and are able to compare and contrast their different properties. Students simulate the creation of sedimentary rock, they also...
