Mars might be full of salty liquid water! Plus, a guide to the upcoming Lyrids meteor shower.

Pluto might seem like the least likely place to find liquid water, but thanks to New Horizons, we have new information about oceans on the dwarf planet and more from the outer reaches of the solar system!

If you've ever gone outside really early on a cold day in fall, you might have seen a thin layer of sparkly ice crystals covering everything! That ice is called frost, and it can only form if the weather is exactly right!

Explore the four inner rocky planets, as Jessi and Squeaks take you on a tour of the solar system!

Colorful, engaging footage emphasizes the fact that phase changes occur all around us. Freezing, melting, vaporization, and condensation are all explained through crisp imagery and colorful animations. This video correlates to the Next...

This captivating program uses the example of water to illustrate the three different phases in which it exists as a solid, liquid, or gas. Special attention is given to how particles in liquids and gases act thus causing them to behave...

In this program students will visually learn how the particles in the various phases of matter influence the characteristics of solids, liquids and gases. Instructive animations and vivid footage illustrate the movement of particles in...

Discover the wonders of "Earth" with our catchy video that makes learning about our home planet fun and engaging! Perfect for kids, this tune will spark your imagination and teach you about Earth's diverse ecosystems and natural resources.

NASA’s Habitable Worlds Observatory "will draw on technologies proven by the agency’s Hubble, Webb and upcoming Roman Space Telescopes," to search for life outside our solar system, according to the Goddard...

If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - which holds around 5 METERS of sea level rise - is...

Pupil outcome: I can identify the part played by evaporation and condensation in the water cycle. Key learning points: - Water doesn’t leave Earth’s atmosphere. It moves around in what is called the water cycle. - Water evaporates from...

Outlines the key features of equilibrium in physical systems, like constancy of properties

Explains how equilibrium is established in physical changes like phase transitions

Describes experimental setups to demonstrate reversible reactions.

Everything about sundogs, lunar halos, ice halos, parhelia, and circumzenithal arcs.

The UAE has joined the space race, skipping the Moon altogether and going straight for Mars. What will the Hope Emirates Mars Mission investigate while in orbit around the red planet?

Where does Earth fit into the Solar System and what makes this planet unique? Physics - Our Solar System - Learning Points. Earth is the third planet from the Sun. 71% of Earth is covered in liquid water, which is vital for life. Earth...

The unique force created by hydrogen bonding gives water some unique properties, which seem to defy the laws of nature. Chemistry - Atoms And Bonding - Learning Points. Hydrogen bonding is a special force of attraction between water...

The Sun is dying, and getting hotter as it does. As life on Earth becomes unsustainable, could we move to Mars? Physics - Universe - Learning Points. The Sun will die in approximately 5 billion years. As the Sun ages, it will get hotter,...

We know that Mars once had a landscape with oceans and rivers, but what happened to it? Physics - Universe - Learning Points. Although Mars is a freezing dry world today, it is thought the planet was once like Earth. If liquid water once...

Scientists have found microbes frozen deep in the Antarctic ice sheets, in conditions very similar to the red planet's surface. Could life exist on Mars, in suspended animation? Physics - Universe - Learning Points. In 2001, a frozen...

A delicate balancing act between the Sun and Earth makes ours the only known life-bearing planet in our Solar System. Physics - Our Solar System - Learning Points. Earth is the only planet with liquid water. If a planet is too close to...
