It's not easy to measure the weather. Pupils learn about what all weather has in common—the atmosphere. Scholars discover how a meteorologists must be able to measure aspects of the atmosphere and decipher the data. They then create a...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Pack just enough to fit. Crews determine what personal items to take with them on a trip to Mars. Each team must decide what to take with them on a two-and-a-half year trip to Mars and whether their items will fit within the allotted...

Hear from deep space. Pupils learn how satellites transfer information back to Earth. They learn about three different ways to modulate radio waves and how a satellite sends information with only 0s and 1s. Using sound, class members...

Take a look at climate change from another angle. Readers learn about the MISR instrument on the Terra satellite and how it studies Earth. Pupils experience how the multiple cameras give scientists multiple views so they can better study...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

The top priority when it comes to food waste is to avoid generating more. Food waste includes all food intended for human consumption that never reaches us, as well as edible food that consumers throw away. As it rots in landfills, food...

Article describing efforts in the 19th and 20th centuries to determine the Earth's age, particularly using naturally occurring radioactivity. It notes that scientific disciplines frequently overlap in the work they do. Questions are...

Discover the ways in which the Earth's surface is always changing and what causes those changes through reference materials and a collection of activities.

Article describing early efforts, beginning with Aristotle, to determine the Earth's age, and the influence of current culture on the acceptability of new and radical scientific theories. Questions are posed throughout about the nature...

Article explaining the history of our scientific understanding of volcanic activity, ending with questions for students about scientific methods and historical contexts.

Article outlining the scientific history behind the evolution of theories about measuring time based on the movement of a pendulum, and about how gravity would impact a pendulum's movement depending on one's proximity to the Earth's...

Researchers are beginning to find data implicating that an asteroid impact and supervolcanoes might have been the beginning of the end of dinosaurs on Earth.

Making Climate Change Relatable to Teens: The goal of my Earth and Environmental Science course is to provide students with the scientific principles, concepts, and methodologies required to understand the interrelationships of the...

Climate change and heat from a strong El Nino played roles in making 2016 the hottest year on record. Understand the specific impacts of climate change.

Article reports on the recent discovery that many suns in the universe host "Earth-like" planets. Includes a vocabularly list.

Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread. Scientists are concerned with the rising temps of Earth.

The buildup of carbon dioxide in the atmosphere is rising faster than at any time since dinosaurs roamed the Earth. The burning of fossil fuels is largely to blame.

Find out why keeping a part of your yard as bare ground is important for providing nesting habitat for native bees.

An illustrated article helps learners understand the water cycle and the distribution of Earth's water.

Around 72 percent of the Earth's surface is found under the oceans. It has always been contributing to the dynamically changing face of the Earth through the tectonic phenomenon occurring at its depths. Such a naturally occurring...

Article reports on the European Space Agency's upcoming program to search for exoplanet in space.

Scientists have learned that when gusts of high-speed solar particles enter our atmosphere, the number of lightning bolts increases. Learn more about how this phenonemon works.

From ABC News in Science, Irene Klotz's article discusses the findings of researchers and scientists related to the discovery of an "Earth-like planet" which is capable of supporting life.
