From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based instructional activity includes a range of learning experiences, from experimenting with the rate at...

Fourth graders observe and identify the effects of weathering and geological activities. They take part in an excellent hands-on group activity called "Erosion Race," in which each group tries to simulate erosion of soil in the quickest...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Coloring pages showcase microbes—bacteria, viruses, and protists. Scholars have the option to download a coloring book and scavenger hunt or color the page directly on the computer. Three paragraphs describe each microbe. 

Eighth graders utilize Internet research skills, and practice their communication skills by presenting their research to the clas. They actively consider the types of hazards for humans associated with Natural Disaters and ways that...

Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...

Wind is a natural resource available around the world. Help your pupils appreciate the power and importance of wind by researching wind farms, making pinwheels, and designing windmills. 

This weathering instructional activity reviews the two types of weathering, chemical and mechanical. Included is a game that assesses if students know examples of chemical and mechanical weathering and how they each affect the earth's...

Students discuss the importance of "land." They review the four types of land classification--urban, rural, agricultural and conservation--and participate in an activity involving an apple that demonstrates the use of land in Hawaii....

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Young scholars use authentic satellite data to produce plots and graphs of sea surface temperature as they explore the seasonal changes of the Gulf Stream.

Excite scholars to design their own planet in this first of five lessons. The instructional activity starts with a pre-activity assessment, a complete lesson plan that is easy to implement, and a post-activity assessment that would...

After a basic introduction to the rock cycle and the three main types of rocks, young geologists can deepen their understanding of how rocks change through a fun learning game. Based on the characteristics and events shared by a reader,...

Viewers learn about three different weather measurement tools in installment five of the 10-part Discover Your Changing World series. They build weather vanes to collect data on wind speed, barometers to determine air pressure, and...

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

Apply scientific principles to designing an experiment to study organisms living on the coral reef in our oceans. Through reading, individuals learn about the coral reef ecosystem and important factors that affect its function....

Students analyze the Greenhouse Effect and the science of greenhouses. For this global climate lesson, students read background information about the 'greenhouse effect' and define 'albedo.' Students examine pictures of clouds, read...

Young scholars discover the interconnectedness of the world. In this global studies lesson, students identify challenges the world faces and craft solutions to the problems they identified. Young scholars present their findings in a...

Students examine how Earth-Sun relationships affect Earth's energy balance and the pattern of world temperatures. Students study a Surface Temperature Regions map and write a paragraph describing the temperature pattern from the Equator...

Students create flubber glaciers. In this glacier dynamics lesson, students experiment factors that may affect glacier speed. Factors include slope, ice temperature, and basal conditions. Students develop hypothesis, conduct experiment,...
