Scientists who study water might be called hydrologists. For this week we will all be hydrologists, that is we will all be studying the earth's waters, their distribution and the water cycle. Focus on concepts similar to the following. Scientists follow safety rules. Scientists are recorders.
Scientists ask questions.
Oceanographers, biologists, botanists, meteorologists, ecologists, and geologists are a few of the groups of scientists who study hydrology. Have a lab coat, goggles, test tubes, and other commonly expected things and have students dress up one of the group as they think a scientist would look. Groups or individuals who are finished early could brainstorm lists of the kinds of scientists they have heard of, or list things they know about science, or write a paragraph about what they like about science. Groups could be divided into 'recorders', 'reporters', 'supply managers', 'timekeepers' etc. After observing posters, groups come back together in large groups to expand the concept that science is all around us.
