Gravity and Its Effect on Planetary Orbits

Why is the sun round? Examine this question, and others, with your pupils while teaching them how to live in a more earth-friendly environment. Pupils explore Sun composition and discuss how solar wind, sunspots, and solar energy affects...

Examine the phenomenon of El Niño and its impact on the environment. Using social studies, language arts, and science, learners will develop a news story on past occurrences of El Nino, its global effect on weather patterns, predictions...

In 1842, Christian Doppler proposed a theory relating the change of wavelengths based on motion. Young scholars observe the Doppler Effect on a small scale in a ball, on a larger scale from a car, and on the largest scale studying the...

High schoolers investigate the greenhouse effect and examine the potential effects of climate change in the Arctic. They construct a mini-greenhouse and test its effect on temperature, analyze historical climate statistics, and conduct...

What does your world revolve around? Challenge the class as they learn about orbits and the effects of them on our modern world. Young astronomers begin by measuring ellipses and calculating the eccentricity of Earth's orbit. Then, they...

A more detailed description and definition of orbitals, and the role they play in the atomic world are the focus of this video. The "P Orbitals" are described by taking a close look at the carbon element's properties. The periodic table...

Does space have its own gravity? And, if so, why do astronauts just float around in the space station? Science sleuths examine the forces acting upon astronauts in the International Space Station with help from the narrator. He...

Discover the transition from circular orbit theories to elliptical orbits. An episode of a video series on astronomy models the different elliptical shapes of the orbits of the planets in the solar systems. Using string, the presenter...

Pore over the properties of plastic. Working through four different stations, pupils investigate some properties of plastic, including chemical decomposition, mechanical breakdown, density, and the ability to infiltrate the food chain....

Where does limestone actually come from? The sixth video in a seven-part series introduces pupils to the quandary of quarrying. The resource examines the positive economic factors involved in digging for limestone, as well as the...
