NASA Lessons in Sea Level Rise
"Sea level rise" - we hear that phrase, but what does it mean, really? How does it affect us? Do I have to be concerned about it in my lifetime? These are all great questions! Sea level rise is the increasing of the average global sea level. It doesn't mean that seas are higher by the same amount everywhere. In fact, in some areas, such as the west coast of the US, sea level has actually dropped slightly...for now.
Bridge DATA - Diatomaceous Sediments: Ooze Clues
Just as ocean beaches display a variety of sand types, the ocean floor has different sediment types. Sediments can come from land, living organisms, chemical reactions in the water column, and even outer space. When skeletal remains of microscopic organisms make up more than 30% of the sediment, it is called "ooze." In this activity, students will plot the distribution of various oozes using information from sediment maps.
The Bridge's own DATA Series is made up of lesson plans (DATA Tips) on many ocean science topics that explore the world of water using the language of science: mathematics. Learn more about the DATA Series.
Join the ocean education conversation! Scuttlebutt is the national email discussion list for educators and scientists interested in talking informally about ocean education ideas, issues and questions.
All educators and scientists interested in marine science education are invited to subscribe. The Bridge staff monitors list activity and often is able to assist in locating expertise to answer questions that teachers post to the list, as needed. The list does not provide research services for students' assignments.
Scuttlebutt carries messages related to marine education that should be of professional interest to many marine educators nationwide. Petitions, political commentary or advocacy, resumes or job requests, requests for donations or votes, crowdsourcing, cross postings and commercial messages are not accepted. Please restrict attachments to a total size of 500kb or less.
