In this ice on Mercury worksheet, students read about the data collected from the NASA Messenger and the Arecibo Radio Telescope indicating the possibility of ice on Mercury. Students solve 6 problems including finding the scale of the...

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

In this sentence correction worksheet, students read the sentences and rewrite them by editing them with corrections. Students complete 4 examples.

Students describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.

Students examine the effects different substances have on proteins. They test different molecules reaction to water. They discover how the amount of water affects the shape of the protein.

Learners how islands form, rising water levels, growth of coral, and volcanoes. They complete Island Investigation worksheets after researching island formation on various Internet websites.

Young scholars identify the major Earth systems, and describe at least ten major uses of water on planet earth. They research major sources of earth's water, and describe general aspects of the hydrosphere.

Students, through video segments, explore what types of animals live in the Arctic and Antarctica. They also clear up any misconceptions they have about penguins or polar bears.

Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...
