Objects appear to be certain colors because of reflection and absorbance. Light is made up of different wavelengths that our eyes detect and convert into colors. The apple looks green because it reflects the wavelengths that correspond to the color we see as green. The apple absorbs all other wavelengths of light.

Journey to the Bottom of the Sea
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they learn about how living in the water differs from living on land. An ichthyologist first explains that ocean creatures have special features that allow them to breathe, eat, communicate, and move in water. (Each feature has its own trading card, which provides more detailed info.)Then students are challenged to "try to make the connection" by playing the Journey to the Bottom
8 Multiple plate collisions and the end of the Iapetus Ocean
Some of Britain’s most dramatic scenery is to be found in the Scottish Highlands. The sight of mighty Ben Nevis, the desolate plateau of the Cairngorms, or the imposing landscapes of Glen Coe can unleash the call of the wild in all of us. Although these landforms were largely carved by glacial activity that ended some 10,000 years ago, the rocks themselves tell of a much older history. The Highlands are merely eroded stumps of a much higher range of ancient mountains. This unit is an account o

Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the triggers that bring on hibernation, and whether internal signals or external season cues are predominant. It also examines the physiological adaptations that occur in hibernating animals. This unit builds on and develops ideas introduced in the

Chiton from the California rocky intertidal zone
Chitons have oval shaped, eight segment hard shells that provide protection for their soft shelled bodies. The plates of the shell allow for more flexible movement of the animal. The entire soft body is covered by the shell.
Saturday Night on the Range: Rural Life in World War I Era Montana
We often like to imagine rural life in the past as timeless, "traditional," and in some way simpler and more authentic. Yet, rural life in the years around World War I, while sometimes recalled as simpler, could often seem very much like life anywhere else. In this interview, conducted by Laurie Mercier in 1982 for the Montana Historical Society, Tom Staff remembers how Montana farmers took other jobs to supplement their incomes. Here he described how the road crew he worked on left camp for dan

Power and the illusion of control Architects and Engineers Skylab: A Home Above Our Home Planet
Niro Sivanathan's latest research investigates why power creates the illusion of control over uncontrollable situations, perhaps leading to some of the risky decisions that contributed to the global financial crisis
Students explore the interface between architecture and engineering. In the associated hands-on activity, students act as both architects and engineers by designing and building a small parking garage.
