This lesson investigates the correlation between the rate of cellular respiration and metabolic rate of Weddell seal pups. Students will collect data of their personal oxygen consumption rate at rest and during exercise, and evaluate how collecting oxygen data can be used to calculate metabolic rate. Students will comprehend that heat is a product of the reaction of cellular
This lesson investigates the effects of different insulators (fur and blubber) on maintaining the body temperature of polar animals. Water balloons filled with warm water simulate the marine mammal. The blubber insulator will be simulated by covering the balloon in vegetable shortening. The fur insulator will be simulated by placing another balloon over the “marine mammal” and adding an
The following presentation was given by Dr. Patricia Yager at the 2012 Arctic Ocean Ecosystem Workshop in Barrow, Alaska. The presentation outlines Dr. Yager's work in biological and chemical oceanography, and focuses on the feedbacks between climate change and marine ecosystems at different locations around the world.
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.
