Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

A lot can change in a year! Investigators observe a video of Earth over the course of a year and complete a KWL chart. Astronomers view a second video, participate in a guided discussion, and discuss the rubric for successfully...

Follow a fabulous slide show on how monsoons form and how satellite technology is being used to observe the phenomena, explaining why they occur. Afterward, visit the TRMM (Tropical Rainfall Measuring Mission) website to access actual...

Fourth graders take a look at the effects of weathering and other geologic activities found in the environments in which they live. Along with a guided geologic walk outside of campus, there is also an effective in-class demonstration of...

Examine predator-prey marine relationships through an interactive lesson design. Learners begin by studying a specific shark species and then analyze real-time shark-tracking data. They also study threats to shark populations and...

Explore the science behind Earth's amazing diversity of life with this lesson on genetics. Looking at specific traits in piebald deer, carnations, and roan cattle, young scientists use Punnett...

Fourth graders observe and identify a variety of weathering and geological activities in the area in which they live. This focuses primarily on what happened during the Ice Age, and how, even today, glaciers are shaping and re-shaping...

Students research Galileo's work and contributions to science. They make a timeline of Galileo's life, discuss the historical context for his book "Dialogue on the Two Chief World Systems" and examine his trial by the Inquisition for...

Youngsters examine resource maps to find out which states are using solar and wind power and discuss as a class various other renewable energy sources. They use a provided data table to record pros and cons to each technology, build and...

What's the difference between base metals and precious metals? Experimenting with natural metals is an interesting way for kids to learn about the world around them. Use a resource that contains over 30 pages of worksheets and...

Though UV radiation can damage skin, it isn't all bad. The third installment in a six-part series allows the class to study the structure and function of skin. They learn about the different types of skin cancer and the SPF rating...

Learners use computer images to explain why the Earth has seasons and examine the phases of the moon. They create 3-D images and present them to the class. They answer a series of questions at the end of the lesson.

Students explore the make-up of the earth and the changes it undergoes in an earthquake. In this earth science lesson, students have two activities as part of a unit. First, to use a Styrofoam ball to model the earth's structure, and...

Students practice addition and estimation. They use tens models to solve the problems related to grocery bags and Earth Day. Afterwards, they complete an activity sheet and draw a large grocery bag decorated with Earth Day messages.

Eighth graders conduct a "Length of Day Symposium." They complete a variety of activities and explorations regarding the earth's rotation, its revolution around the sun and the cyclic changes in climate and energy distribution on the...

Egg-cellent! A series of lessons on eggs awaits your class. They study everything from how eggs are formed in a chicken's body to how well they float, how to determine if they are raw or cooked, the strength and construction of the...

Your class will watch as one child orbits the sun as Earth, while another orbits as Mars. If the timing is right, they will see the repetitive dance between the two planets and discover how often they are opposite from each other. For...

Working in cooperative groups, young scientists research and report on how undersea volcanic activity may benefit marine ecosystems. There are many links to websites that you can use to stimulate curiosity or for pupils to use for...

Collaborative groups work together to report on the volcanic activity leading to island formation and construct models to demonstrate the process. Consider having each group present their project to the rest of the class. There are many...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Earth science learners create a two-dimensional topographic map of the floor of the Aegean Sea. They use it to then create a three-dimensional model of the ocean floor features. This comprehensive resource delivers strong background...

You may not be able to take a field trip to the moon, but that doesn't mean your class can't study moon rocks. Using graham crackers as the moon's bedrock and powdered donuts as micrometeorites, young scientists simulate...
