Young scholars calculate the escape velocity of planets in our solar system and use that knowledge to calculate the escape velocity for NGC 2300 group. They then suggest reasons for the escape velocity to be higher than possible given...

Are you having trouble deciphering the Next Generation Science Standards on the website, or just trying to find the standards for your grade in a quick-and-easy format? If so, here is a free and easy-to-navigate app made with you in mind.

Your class will watch as one child orbits the sun as Earth, while another orbits as Mars. If the timing is right, they will see the repetitive dance between the two planets and discover how often they are opposite from each other. For...

Cartoon children compare the earth's age to timescales that we understand:a calendar year, the thickness of a book, the human lifespan. This smart film clip is definitely worth adding to your geologic timescale lesson! If you subscribe...

Why is the spin of a black hole important? Scholars explore spinning black holes and how they relate to momentum, matter, and mass. They investigate the different parameters that are used to measure black holes by understanding how they...

How did the planets form? An interesting video from the SciShow Space series identifies the differences between the inner and outer planets and how the history of the solar system's sun put everything in its place. Viewers also learn...

Space stations provide opportunities for space exploration and research. Individuals see how scientists build space stations and put them into space. Viewers explore the history of space stations, the different types of space stations...

How much do you actually weigh? It all depends on gravity. Scholars explore why gravity varies in different locations and how these variations affect weight.

A mass extinction event caused by an impact usually leaves a crater. Scholars use data from 10 different sites around the world trying to determine where to look for the crater. They use data, listing the amount of various minerals to...

How do scientists know the difference between a meteorite from space and a regular rock from the earth? Scholars read a passage and answer comprehension questions about the creation of the solar system. They extrapolate the main ideas to...

Should we be afraid of a large asteroid impact on Earth today? Young scientists estimate the size and composition of an asteroid similar to the one that caused the K-T mass extinction. They apply algebraic formulas to answer questions...

Understanding the size of the universe and its many galaxies challenges perceptions, and this visual journey through the universe helps create a scale. Starting from Earth and going out past our galaxy, thus backwards in time, the entire...

The motion of the earth around the sun creates many different patterns in our world. Watch as a video instructor explains the patterns of moon phases, sunrise and sunset times, seasons, tides, and constellations among others. He also...

Why do planets orbit the sun in ellipses when moons orbit their planet in circles? Pupils control the semi-major axis, eccentricity of the orbit, and position angle. The resulting orbital appears with the related force vectors as...

Why are there launch windows when traveling to outer space? Scholars explore the trajectory of traveling from one planet to another. By adjusting the departure and destination planets, as well as the launch date, they observe the ideal...

Enceladus, one of Saturn's moons, holds water beneath its surface. The lesson is an interesting tutorial where pupils learn about Saturn's rings and one of its moons, Enceladus. Pupils move through the tutorial at their own pace,...

Was the universe created or has it always existed? Here is a five-part series about the origin and evolution of our universe. To start, part one looks at celestial objects and allows pupils to discuss and share their knowledge about...

The propellant needed for space explorations runs in the thousands, while paying to get the craft into orbit costs millions! In the second installment of three, two activities explore laws of conservation of energy and momentum. Using...

Lasers are so precise, they can detect a change the thickness of a human hair in the distance from here to the nearest star. To replicate NASA's LISA mission to measure gravitational waves in space class members build a model of a laser...

This space is reserved for matter. After finding the density of a foam ball, young scientists predict the density of a larger ball. When they encounter a discrepant event, they must theorize an explanation. These concepts are linked to...

Should Pluto be considered a planet or a dwarf planet? Scholars research planets in our solar system to understand their similarities and differences. It also includes memory activities related to the order of the planets. 

Prompt scholars to discover the expansion of the universe themselves. Using photographs of other galaxies, they measure and then graph the size and distance of each. Finally, they draw conclusions and prove the universe is expanding.

What needs to go into a satellite that is going on a very long trip? This resource provides information about the New Horizon spacecraft and its mission to study Pluto. The packet includes a section with information about the...
