We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the...

Earth's climate system has been remarkably stable over the last 20,000 years or so. Human civilization developed in that time span, and our world's average temperature warmed by about 5 degrees C to the temperature it is today. This...

This project observes and analyzes the stable isotope composition of water vapor and precipitation, primarily at the 300 meter Boulder Atmospheric Observatory tower. The measurements are made using an optical measurement technology which...

In this section, I talk about the sun as a source of energy, consumers vs. producers and cycles found in nature

Life as we know it requires three ingredients: energy, organic...

We were lucky enough to get early access to THE WORLD'S LARGEST INDOOR TROPICAL RAINFOREST at The Eden Project. Whilst playing on the awesome cloud bridge we thought what better question to tackle than...How do Rainforests Make...

Can we do stoichiometry regarding phase changes? Sure! If we know how many moles of a substance we have, and the energy associated with each mole of that substance undergoing a particular phase change, we can get the energy associated...

Humidity is simply a measure of how "wet" the air is in a specific place, or the amount of water vapor present in the air. However, it's important to note that humidity is an umbrella term that can refer to three different types of...

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite has been scanning Earth for 20 years and now has a long enough record to help support climate change research. AIRS data on Earth’s atmosphere are...

This video discusses the different factors that can affect the nature of volcanic eruptions. It provides examples of explosive and calmer eruptions, such as the 1991 eruption of Mount Pinatubo in the Philippines and the eruption of Mount...

On May 4th, 2016, the Hubble Space Telescope made the first spectroscopic measurements of two of the three known Earth-sized exoplanets in the TRAPPIST-1 system just 40 light-years away.

Learn about why thunderstorms, tornadoes, hurricanes, and other weather phenomena typically form during the summer.

Learn how to make a wispy cloud come out of your mouth, even when it's not cold out. Like any awesome trick, physics is to thank for the mouth cloud. This simple and fun demonstration can be used to explain the cloud in a bottle...

This live-action video program is about the word air. The program is designed to reinforce and support a student's comprehension and retention of the word air through use of video footage, photographs, diagrams and colorful, animated...

New research by France’s National Center for Scientific Research suggests that water on Mars is evaporating faster than previously thought. <br/>

The Hubble Space Telescope has captured even more evidence of water vapor plumes on Jupiter's icy moon Europa. The probable plumes appear to be repeating in the same location and correspond with a relatively warm region on...

The video explains the concept and application of distillation, a technique used to separate mixtures by physical means based on the components' physical properties such as solubility and boiling points. The video explains the process of...

In this video, we delve into the fascinating world of clouds. Join us as we uncover the secrets behind these fluffy formations and learn about the different types of clouds, how they are formed, and what they signify. Investigating...

This kitchen science video lesson is all about crystallisation and the formation of crystals. Students will love this engaging and interactive video as they learn about science they can do at home.

Thunder, lightning, and rain are important elements of a thunderstorm. Discover how thunderstorms form and the three stages they go through. Also, learn the hazards associated with thunderstorms, including lightning, hail, tornadoes,...

Prof Hal Sosabowski demonstrates this simple yet effective experiment, which reveals several properties of solid carbon dioxide. Hal shows us how clouds of water vapour can be formed, how carbon dioxide is denser than air, how a gas...

This live-action video program is about the word transpiration. The program is designed to reinforce and support a student's comprehension and retention of the word transpiration through use of video footage, photographs, diagrams and...

A conversation with James Cockrell, Project Manager for Small Spacecrafts.

It talks about the availability, renewal and scarcity of freshwater resources. It lists the factors responsible for freshwater scarcity.
