Third graders research about the location of different planets from the sun. In this earth science lesson, 3rd graders discuss the weather in their place and identify common weather terminologies. They explain how tornadoes form and...

Students observe and analyze weathering. In this earth science lesson, students demonstrate physical and chemical weathering in two experiments, then write questions for a class Jeopardy game.

Students investigate comets. In this space science lesson, students study overhead transparencies of the orbits of Earth and a comet. Students identify various locations and times where comets would be visible from Earth.

In this Earth worksheet, students find 8 words, related to the Earth, in a puzzle. Students also use the words to answer 8 questions about the layers of the Earth.

Students explore Earth science by completing a could identification activity. In this weather lesson, students discuss the different forms of measurement for the weather of Earth. Students discuss global warming and examine a list of...

Students identify the main components of the solar system. In this earth science lesson, students order the planets according to their distances from the Sun. They differentiate planets from dwarf planets.

Students simulate the movement of the Earth using their body motion. In this earth science lesson, students explain how this causes seasonal changes on Earth.

Middle schoolers examine the major events that have taken place in the Earth's development.  For this Earth lesson students view a video and put major events in chronological order. 

Middle schoolers create a timeline.  In this Earth's History activity, students research the history of life on Earth and use the information collected to create a timeline.  Middle schoolers also answers the provided...

Eighth graders compare and contrast weather and climate. In this earth science lesson, 8th graders research weather data site and analyze historical data. They present their findings in class and explain identifiable trends.

Students explore the different types of renewable and nonrenewable energy sources. In this earth science lesson, students discuss the pros and cons of each type. They conduct a variety of experiments on renewable energy.

Students explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students explore different natural and manmade disasters through a webquest. In this earth science lesson, students explain their causes. They also discuss how disasters affect society. 

Ninth graders will identify/understand the differences between soil and dirt. They will classify soil color accurately and use Munsell notation to describe it (Munsell books provided).Students will classify soil texture using the feel...

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

What factors affect the creation of glass? Youngsters work with sugar crystals as a simulation of glass-making. First, they melt some crystals, then they add water and stirring action as a modifier, they melt sugar in water without...

Story elements such as conflict, character analysis, resolution, and moral are discussed and charted as elementary children read folktales involving animals. An element of science is also introduced as learners discover what a keystone...

A lamp, four globes, and some signs taped around the room are all you need to set up a solar system simulation for teaching how Earth's tilted axis creates the seasons. (Sticky dots are also needed, but not mentioned in the materials...

How many times have you traveled around the sun? Aspiring astronomers grasp what a year is and they differentiate between orbit and rotation by walking around the sun right within your classroom. Place a lamp in the center of the room to...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Historians have proven that as early as 1497 skilled navigators were using a kamal to sail across oceans. Scholars learn about navigation tools and astronomy before building their own kamals. They then learn how to use it to determine...
