NOAA Data in the Classroom: Understanding Ocean and Coastal Acidification part of CLEAN Collection

Through the five lessons in this module, students will explore relationships between carbon dioxide, ocean pH, and aragonite saturation state. By examining these parameters using interactive graphs ...

NOAA Ocean Odyssey: Ocean Currents part of CLEAN Collection

This lesson provides a demonstration and lesson focused on ocean currents. The demonstration of how cold water and warm water interact is a strong learning tool for the topic.

NOAA Ocean Odyssey: Cycles in the Ocean part of CLEAN Collection

In this activity, students connect art and science by creating a drawing and conceptual model of the thermohaline circulation. Students get to create drawings to understand how water moves in the ...

It is a slippery slope part of CLEAN Collection

This is a demonstration that includes a review of scientific abstracts that show how warm water currents speed up ice sheet loss and sub-ice water infiltration into the Southern Ocean.

NASA Global Warming Demonstration part of CLEAN Collection

This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an ...

Thermal Expansion Model part of CLEAN Collection

This activity allows students to demonstrate the thermal expansion of water for themselves using water bottles and straws. The discussion allows them to explore the connection between this concept ...
