An experiment where polarized light is shone into a solution of sugared water, causing each of the colors in white light to change direction in varying amounts.

Activity 4 investigates How does electron distribution impact our observations? Students have described how properties of molecules change depending on what atoms make up the molecule. In this activity students will use those ideas to...

Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding...

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

Lots of information here about glaciation, types of glaciers, the formation of glacial ice, changes in glacier size, how glaciers move, glacial erosion, landforms produced by glaciers, glacial deposition and drift, effects of glaciation...

Use this site to learn about the effects of persistent organic pollutants on the ecology of Antarctic coastal waters. Information is presented for both teacher and student researcher.

Construct a story about the Inuit or the polar bear from a series of pictures that can be put together in a sequence.

Did you know that penguins can survive for more than 100 days without food or water? Discover more educational facts about these fascinating birds when you explore this site.

[Free Registration/Login may be required to access all resource tools.] Covers solubility in water and polar molecules.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

In this learning module from The Concord Consortium, students will investigate how polar and nonpolar regions in big molecules interact to result in certain shapes and properties for those molecules.

"Global Circulations explain how air and storm systems travel over the Earth's surface. The global circulation would be simple (and the weather boring) if the Earth did not rotate, the rotation was not tilted relative to the sun, and had...

One of the ships the United States has stationed in Antarctica is heading to warmer waters for intense cleaning.

This site from the University of Frostburg provides an explanation of the process by which nonpolar molecules dissolve in water.

Here is a comparison of the atmospheric composition of Earth, Venus and Mars.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Young scholars will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and...

Wind is air in motion. It is produced by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to...

Through nine lessons, students are introduced to a range of energy types--electrical, light, sound and thermal-as well as the renewable energy sources of wind, hydro (water) and solar power. Subjects range from understanding that the...

Media-rich lesson plan in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

This Smithsonian website has a brief, but thorough, article on the Walrus that also includes pictures and an extensive quote from naturalist Edward Nelson.

The problems of global warming are examined from the following perspectives: climate pattern changes, health effects, and ecosystem disruption. You will also find a number of NRDC related webpages further amplifying the topic of global...

Explore the chemical properties involved in surface tension.

Learn about six geological processes from Luke W Interface Designs that are happening or have happened on Mars. Ex: aeloian, cratering, landslides, volcanic, and more.

A map showing Australia and the Western Pacific in the Glacial Age (the Maximum of the Fourth Ice Age, about 50,000 years ago - Wells). While the waters were held up in the polar ice caps, the sea-level was low enough to enable...
