Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Learners discover hazards related to volcanoes and predict the effects these hazards have on people and land. As blossoming geologists explore various volcanic eruptions, including the hazards associated with them, they...

When oil spills happen, how is the oil cleaned up? Pupils of polymer science discover an amazing substance that turns oil into a solid during a microscale experiment. Individuals observe oil or paraffin before and after addition of the...

Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Time to rock out! Discover the "life" cycle of the average rock using an illustrative stations lab and stimulating pairs game. Roll the dice to determine your fate: will it be melting in magma or chilling out to form igneous rock? The...

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...

The Mammoth Lakes area regularly releases warnings to hikers and skiers to be careful because melting snow releases trapped gases from volcanic vents. The 17th lesson in the 20-part series opens with a demonstration of carbon...

Human impacts on the environment can sometimes be difficult to measure, especially under water! An activity centered on ocean acidification gives science scholars the opportunity to examine the effects of carbon dioxide on marine life....

There's nothing better than a cool breeze blowing in from the ocean. Scholars explore how water affects change in temperature using a hands-on experiment on climate. They use measurement tools to compare the continental and oceanic...

Turn your class discussion of rock formation from ho-hum to holy hornfels! Junior geologists gain experience in identifying rock types and rock origins, with an emphasis in hypothesizing the environment needed to form certain...

Investigate the different types of pollution that storm drain runoff carries into oceans, lakes, rivers, and streams with this class demonstration. Using an aquarium and an assortment of everyday items that contaminants like motor oil,...

Carbon is in the air; should we care? Teach the class why it is important to pay attention to carbon levels and how the world population and various countries across the globe affect the carbon levels in the atmosphere. High schoolers...

What makes a watershed? What are the natural and human features of a watershed? How do human features affect watersheds? Where can I find my local watershed? These questions are thoroughly explained in an informative watershed interactive.

Bring together a study of two major scientific topics with a lesson on the relationship between pollution and evolution. With the help of a PowerPoint presentation, hands-on activity. and class demonstration young scientists learn...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

After challenging themselves to correctly choose the form of erosion and length of time required for a given landform to develop, earth science class members model mechanical and chemical weathering with various lab demonstrations over...

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...

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...

Three days of erosion exploration await your elementary geologists. Learners begin by examining rivers via Google Earth, then they model water flow in sand, and finally, they identify resulting landforms. This lesson is written...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

El Nino, La Nina ... and the Santa Maria? The 11th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explains the mechanism of El Nino/Southern Oscillation. Pupils use previous data to determine...

One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...

These rocks are HOT! Well, they used to be, anyway. Take young geologists on a two-week journey through the life and times of the average igneous rock. Lab groups work together to hypothesize about intrusive and extrusive igneous...
