As a follow-up, students read two short articles on the connection between hurricanes and global warming and discuss these articles in context of what they have learned from model output.

In this middle school and high school unit, students compare and constrast Arctic expeditions of the past (1893-1896 Fram expedition) and the present (2019-2020 MOSAiC expedition) to prepare for the Arctic of the future.

Once the pride of the German Navy, this 700 foot long heavy cruiser was used by the U.S. as a test target for not one but two atom bombs at Bikini atoll. Today, at the bottom of the ocean, the radiation levels of the Prinz Eugen are low enough for safe exploration. In this video, Jonathan joins historian Mark Miller on a trip to explore this mysterious shipwreck. What they find about the condition of this wreck is surprising. Please see the accompanying lesson plan for educational objectives, discussion points and classroom activities.

Research physical scientist, Dr. Dalia Kirschbaum, is featured in this short (~3 min.) video. Dr. Kirschbaum explains how the integration of her initial interest in math and her subsequent interest in the science of natural disasters lead to her career focus of landslide modeling. Now part of the NASA Global Precipitation Measurement (GPM) team, she communicates about the GPM mission and data to the public and to others who use it in their work and/or research.

Do shark feeding frenzies really exist? Will sharks turn into a bunch of cannibals if they start competing for food? In this video, Jonathan wants to find out, and travels to Micronesia for an experiment. You won‰ŰŞt believe the fantastic result! Please see the accompanying study guide for educational objectives and discussion points.

Course description: introductory lab science course that examines the four major categories of oceanographic study: geological, physical, chemical and biological. Emphasizes the geological and geophysical aspects of the sea floor; physical and chemical properties of sea water, waves, tides, ocean circulation and currents; marine ecosystems; and ocean utilization.

The purpose of this brief (~15 minutes) activity is for students to directly observe some of the unique properties of water that are the result of hydrogen bonds, such as capillary action, adhesion, cohesion, and surface tension. Students will compare the behavior of water to that of vegetable oil, a non-polar liquid. I have created an activity handout that can either be given to directly to the students or used as a guide by the instructor. It includes vocabulary terms and a discussion "answer key" that should be edited if given directly to students. There is also an "extension activity" that addresses the concept of immiscible solutions.
