Students determine what an anemometer is and how it measures wind speed. They decide on a place to put a wind turbine by using an anemometer. They examine the role that engineers play when using wind speed to determine a place for wind...

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

Students investigate why leaves change color. In this chlorophyll lesson, students examine how chlorophyll effects the color changes in leaves. Students take pictures of changing leaves, and create a class quilt showing the changes of...

Students design and conduct an experiment to test three organic pesticides to control ants. They view a video that demonstrates ant behavior and the role of pesticides in insect control. In small groups, they set up behavior...

Second graders discuss worm composting. In this decomposition lesson, 2nd graders look at the anatomy of the worm and how it eats food. They have their own worm bin and review what foods can and can not be given to the worms for...

Third graders read, write, and listen to information about the sun and its effects on the Earth.as it relates to its axis, orbit, rotate, and revolution.  In this solar system lesson, 3rd graders examine how the sun...

Third graders learn how to use solar power.  For this sun, technology and energy lesson, 3rd graders learn how the solar power from the sun can give off energy, learn about solar panels, discuss their uses and benefits, and design a...

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

Learners conduct a series of experiments to explore carbon dioxide properties. In this chemistry lesson plan, students explain the production and uses of this gas. They measure its amount in soda and waste product of yeast.

Discusses the details of chemical weathering such as carbonation, cation exchange, chelation, oxidation and hydrolysis.

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on chemical weathering. Review questions are included at the bottom of the study guide.

In this Earth Science field investigation, students will make observations of the rock above and below the Minneopa State Park waterfalls. Students will then make observations of gravestones at Minneopa Cemetery. Through these...

Explains what weathering is and gives lots of examples of mechanical, chemical, and biological weathering.

A video and a short multiple-choice quiz on the topic of weathering and erosion, what they are, and how they alter the Earth's surface.

[Free Registration/Login may be required to access all resource tools.] Variables that affect the rate of weathering.

For this activity, students will discover some of the factors that influence weathering of the monuments in a cemetery. These factors may include the type of rock, length of time the rock has been exposed to the elements or the amount of...

Smithsonian in the Classroom presents Building Up, Breaking Down. Teachers can download this comprehensive teaching package in which students investigate how buildings weather. See what happens to a building once it has been erected....

Learn about physical and chemical weathering.

In this interactive tutorial, you will learn about the types of weathering and erosion that rocks and landforms undergo. This will lead to a discussion of soil and the types of soil. Lastly, you will learn about mass movements of soil,...

This activity simulates the way that dissolution, a chemical weathering process, leads to the formation of caves.
