Humans are creative. They try to solve problems in original ways. For example, some scientists are thinking of ways to decrease the amount of greenhouse gases in the air. Other scientists are thinking of ways to limit the amount of sun that reaches Earth so that the Earth won’t get so warm. Like most ideas, there are pros (good
Textbooks say that carbon dioxide is a greenhouse gas and can make earth's climate hotter. Try this lab to see if carbon dioxide gas can really act like a greenhouse.
Objectives
Students should be able to make a hypothesis, perform an experiment, analyze data and write a conclusion based on the evidence from their experiment.
Students will engage in a hands-on activity to help them consider what students in a tropical climate do to prepare for recess compared with students who live in the interior of Alaska.
Objectives
Students will:
* Compare what students in a tropical climate do to prepare for recess with students who live in the interior of Alaska.
* Learn
Through activities, video observation, experimentation and the construction of a Remotely Operated Vehicle (ROV) students will learn about the chemical and physical properties of sea ice.
Objectives
Students will be able to answer main questions of where sea ice is, how it is formed, why the ice is important, how it is classified by indigenous people and scientists, how
The title of this lesson, 'Ssssno Seals' is a play on words. Will the ice seals survive? Yes or No? Paul Lukosi is a high school teacher in the lower Yukon River Delta, 6 miles from the Bering Sea...as the slough goes. The village he teaches in is heavily focused on family and culture, and has survived for thousands of
Nature creates its own density column in marine systems, which is extremely important for the triggering of the spring bloom of phytoplankton. Phytoplankton are an important food source for all organisms- from microscopic zooplankton to large marine mammals such as walrus and whales. The different salinities (and therefore, different densities) of water help to stabilize the water column (by limiting
Students will review charts of day length to determine when the sun will set at Toolik Lake.
Objective
Students will learn the following:
* The sun is the major source of energy for phenomena on the earth's surface, such as growth of plants, winds, ocean currents, and the water cycle.
* Seasons result from variations in the
