Polar ice samples provide scientists with valuable information about the condition of the atmosphere for hundreds of thousands of years in the past. Of particular interest is the amount of carbon dioxide in the atmosphere and its...

Raise children's awareness about the importance of conservation with this hands-on science lesson. Start by breaking the class into groups and having them collect trash from around the school or local park. Students then use the provided...

When it comes to the environment, no variable is constant. Class members graph behavior over time for the thneeds produced over truffula trees chopped down over the course of Dr. Seuss's The Lorax. 

Discover the connection of native peoples to their natural world, including cultural and agricultural practices, by studying the Zuni people of the American Southwest. This lesson includes examining a poster's photographs, reading...

A lesson introduces the reproduction rate of E. coli though a video. Then scholars complete a data table and graph of reproduction rates in ideal conditions as well as less than ideal conditions. 

Dust is everywhere around us; it's unavoidable. But what exactly is dust and are certain locations dustier than others? These are the questions students try to answer in an interesting scientific investigation. Working independently or...

Scholars use data to analyze and determine which sets of information need to be counted. They create a model to explain differences among chemical elements using graphs to prove concept mastery.

Traveling through space is an amazing experience, but it definitely takes a toll on the body. After reading an article and watching a brief video, learners perform an experiment that simulates the effects of zero gravity on the...

Can microorganisms live in the dry, cold climate of Antarctica? Young scientists view a research project measuring microorganisms in the Taylor Glacier. They record the findings from dirty ice, clean ice, boots, sediment, and more. Then...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Capture the engagement of young mathematicians with this upper-elementary math lesson on measuring time and distance. Using Google Maps, students first measure and compare the distance and time it takes to travel between different...

Looks at how people use natural resources and ways to conserve natural resources in this module. Module reviews over conservation, natural resources, and precycling with explanations, graphs, and pictures.
