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...

Students 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 an...

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...

Orbitals are the focus of this video. Sal introduces Neils Bohr, who is the scientist who came up with the theory behind orbitals. Students view graphics which portray the orbitals, their energy shells, and how they correspond to the...

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...

Let me get an angle on this! Investigate the orientation of a photovoltaic panel and its effect on efficiency. By using a light source, learners collect and plot current output to determine the ultimate orientation. The resource includes...

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...
