This lesson focuses on the diffusion of gas molecules across the cuticle membrane of sea spider legs and the role body size plays in the ability of sea spiders to uptake gases. Students construct model sea spider legs of varying diameters and use them to investigate the relationship between surface area-to-volume ratios and diffusion.
This lesson introduces students to krill, their importance in ocean ecosystems, and the physical structures that make up the krill body. The students will then use the principles of a "floater" species and design their own krill, hopefully having a class competition to see who can build a better krill.
Objectives
Students will understand the importance of krill in
Rings of life is a comparative lesson allowing students to investigate growth rings in walleye Pollock from the Bering Sea and Ponderosa Pine trees.
Objectives
Students will be able to compare and contrast growth rings on fish and trees, showing just one of the tools scientists use to monitor the health of different ecosystems. Students will also be able
This activity is designed to make a connection between a group of scientists and the students.
Objective
Students will learn that scientists are people too.
Preparation
The teacher will need to contact a group of scientists to make sure they would like to participate in the project and to explain to them the goals of the
The Kuril Biocomplexity Project is a National Science Foundation-funded research project led by the University of Washington and being conducted by a team of American, Japanese and Russian scholars and students who are examining a 5000-year history of human-environmental interactions along the Kuril Island chain in the northwest Pacific Ocean. This is the link to the project website.
Students use data and pictures of a destroyed wind sensor, to develop a theory of what happened to the station. They then develop a plan to make sure the station is not destroyed again.
Objective
Students will be able to use data to develop a reasonable hypothesis.
This website contains gorgeous pictures and interesting background information on Antarctica, including history, environmental conditions, and research. A twelve-minute overview can be followed by longer segments on Antarctica's weather, Forecasting, and Antarctica and global climate.
To view the module, you will have to register. Once you have created a login, you will be forwarded to the Antarctica module. Additional modules
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
