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. 

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

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...

More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the...

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

The 12th lesson in a series of 20 opens with a demonstration of exponential functions using pasta. This concept is connected to the Richter Scale, which is also an exponential function. Scholars compare the exponential scale that...

A multi-part lesson opens with a review of p waves and s waves. Then scholars use a simple s wave simulator to view the way the wave travels. Next, pupils use cups and various fluids to simulate p waves moving through different...

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...

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...

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...
