Have you ever stretched out a Slinkie so much it wouldn't go back to its original shape? Slinkies, like all springs, follow Hooke's Law. A simulation uses springs and masses to demonstrate kinetic, potential, and thermal energy. It...

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...

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...

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...

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...

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...

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...

Scholars take off on an interactive spaceship to explore a historical timeline of the big bang theory. They learn about the evolution of mammals and humans, the formation of stars and planets, and the chemical composition of the early...

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...

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...

The Big Bang Theory is more than a television show. Pupils read how Edwin Hubble observed other galaxies and noticed that the galaxies are moving away from each other. Scholars learn about the idea of the big bang and what happened next...

What's life like in a hydrothermal vent? Find out in part five of a 13-part series. Learners journey to one of the harshest environments on the planet, the hydrothermal vent, to learn about the creatures that survive the extreme...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

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...

Titan is Saturn's largest moon and has its own atmosphere. An attention-grabbing tutorial allows learners to analyze the spectrum of Saturn and Titan to determine their elemental compositions. Scholars compare a known element's spectrum...

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...

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...

Rocks and minerals are great on their own, but they also turn into some pretty amazing stuff! An online lesson explains the different types of materials we get from rocks and minerals, including glass, plastic, and coins. An embedded...

Illuminate the information about stars. Pupils respond to 10 multiple choice questions about stars. The questions cover topics such as the size of the Milky Way Galaxy, the Sun, and the life cycle of a star. The resource works as a...
