In this lesson, students will conduct an investigation to discover how the behavior of hermit crabs change as water temperature changes.
Goals
Students will understand and practice the steps of a science investigation through an investigation about hermit crabs’ reaction to changing ocean temperature. Students will understand that as ocean temperatures increase some animals will adapt and some will
This lesson introduces students to the impacts of increasing ocean temperatures on marine life. Through this kinesthetic activity, students will learn more about marine ectotherms and what researchers in Antarctica have learned so far about how increasing temperature in Antarctic waters will affect their growth. Through the elaborate section of the activity students will connect what they learned about
Students will use marshmallows to simulate toxins in the environment. Concentrations of these toxins will be modeled and calculated as they bioaccumulate up the food chain. Methylmercury and POPs are substances that bioaccumulate in the Arctic food chain. OASIS scientists studied these in Barrow, Alaska. (See Ocean Atmosphere Sea Ice and Snow (OASIS) Project at www.polartrec.com)
Students will discover how a simple action such as turning on a television will lead to toxins in our food supply. Many of these toxins concentrate in the Arctic because of long-range transport of pollutants in the atmosphere. Scientists in the OASIS project (http://www.polartrec.com/ocean-atmosphere-sea-ice-and-snowpack-interactions) study these pollutants in the Arctic. Students will learn about actions that they can take to
This activity is designed to take place near or at the end of a unit on the ocean floor. Students should be familiar with the physical features of the ocean floor including the continental shelf, abyssal plain, seamounts and guyots, seafloor ridges and trenches, and submarine canyons. The students should have also previously learned about sonar methods for mapping the
In this lesson, students learn about what archaeologists do and then practice implementing these skills with "real artifacts".
Objective
Students will:
* be able to define an artifact and an archaeologist.
* use evidence to support their decisions about the origin and use of an unknown item.
