A set of seven slides presents an artist's rendition of our solar system, specifically, the asteroid belt, Kuiper Belt, and our outer planets: Jupiter, Uranus, and Neptune. The slides are beautiful, and a printable set with text is...

What a neat interactive that interacts with the amount of water on Earth's surface. It begins with a brief audio introduction of the Blue Planet and how it got its name. Then, users click on the activity to play a game...

Stunning images make up this slide show on the inner planets of our solar system. While visiting Mercury, Venus, Earth, and Mars, viewers also are introduced to the International Space Station and the Spirit Rover on Mars. Follow this...

Studying what you can't see can be challenging. Discover how scientists use indirect measurements to prove the existence of planets and estimate their sizes. The introduction explains the symbiotic movement of planets and stars during an...

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...

Yes, Venn diagrams are helpful in science, too. Learners use an interactive to classify celestial bodies as having moons, as dwarf plants, as both, or as neither. They answer a set of challenge questions based on the Venn diagrams they...

Does assessing Earth Science vocabulary making your head spin? Test scholars' knowledge of revolving and rotating using an interactive tool. The movement of a new planet and its moon is in their hands, allowing them to explore...

Get to know our little part of the vast universe. Learners read about the common and not-so-common facts about each of the planets in the solar system. The interactive lesson includes a large amount of information as well as a quiz to...

Not everything revolves around the sun! Believe it or not, there are planets, called exoplanets, that orbit stars other than our sun. Learners use an interactive online resource to research several of these planets. They learn about the...

Kepler decided to think outside the box and discovered that planets orbit in elliptical patterns. An engaging activity demonstrates the elliptical orbit pattern in relationship to the area of a planet to explain Kepler's Second Law....

Planetary atmospheres vary greatly from planet to planet. Explore these variations by experiencing the motion of the atmospheric molecules through an engaging simulation. Pupils discover that temperature and mass contribute to...

Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

Extinctions constantly occur, but what sets off a mass extinction event? Young scientists study the data from the previous five mass extinctions to better understand their causes. Then, they learn the impact each extinction had on our...

Creating a solar system map is a snap thanks to a hands-on activity! Science scholars explore the solar system by building it wherever they choose during an interactive from PBS's Space series. Users pick both the location and scale for...

Earth's thick atmosphere plays a vital role in the ability of the planet to sustain life. Learn about the layers of the atmosphere and their properties, how the gases surrounding the earth help protect the planet, and a little about...

Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...

The winds of change are blowing in our very own solar system!  But what makes some heavenly bodies more affected by solar winds than others?  Pupils discover the concept of magnetic forces at work in space in this...

Tornadoes and hurricanes and blizzards, oh my! Severe storms are always occurring somewhere on the planet. By reading through these slides, learners discover the characteristics of each type. Have them do this as homework and then take...

Fly around the Martian surface. Pupils view a presentation on the planet Mars featuring a flyover that shows different views of the surface where rovers have landed and explored on different missions. As individuals watch the images, the...

Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...

Create your own solar system using a simulation. Young scientists explore the components of a stable solar system through trial and error. Using the simulation, they place planets and watch as they orbit safely or cause fatal collisions.

Budding scientists fall hard for a gravitational field strength activity! Physics pupils compare the masses and distances relative to the center of planets using an interactive from a Circular and Satellite Motion series. Individuals...

Develop an understanding of the universe. Learners answer 10 multiple choice questions about several topics in astronomy. Questions contain information about the age of the universe, gravitational attraction, galaxies, planets and comets...

Earth's climate changed drastically throughout the history of the planet, so why do scientists blame humans for recent changes? Observe data covering the history of the planet that proves the natural climate change patterns. Then, learn...
