Dive into an exploration of the water cycle cycle with this simple earth science instructional activity. After first discussing where rain comes from, young scientists define the...

An excellent lesson on the water cycle! In it, learners should gain a general understanding of the water cycle, along with how water first falls as precipitation, then ends up coming out of our faucets. This lesson nicely integrates...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Hydrology hopefuls learn about their local watershed. Through discussion and online interactives, they see that their habits affect the water supply. The lesson concludes with a pledge to filter out bad water usage habits. It makes a...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...

Global warming isn't just an issue on land; deep ocean waters are also showing troubling signs. Young scientists learn more about deep water corals and the many recent discoveries researchers have made. Then they examine data related to...

How is energy transferred within an ecosystem? What would happen to a food web if one of the organisms was removed? Elementary or middle school ecologists examine these questions and more in a comprehensive 5E learning cycle lesson....

Guide your students through the process of opening up a frog. The resource provides step-by-step instructions for dissecting a frog, as well as guiding questions to answer throughout the lab.

Engineering challenges are not just man-made ... nature has its own set of them. A hands-on STEM activity has groups designing a seed dispersal system. Each group can only use one sheet of paper — a tough task!

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...
