Ocean Acidification in a Cup part of CLEAN Collection

This model of ocean-atmosphere interaction shows how carbon dioxide gas diffuses into water, causing the water to become more acidic. The video demonstration and instruction provide an explanation of ...

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 ...

Your Own El Nino part of CLEAN Collection

This activity allows students to make El Nino in a container, but it might work better as a teacher demonstration. The introduction and information provided describe El Nino, its processes and its ...

Sea Level Rise part of CLEAN Collection

This very short video introduces the concept of sea level rise and ties it back to global warming. The video is brief, basic, and clear. It can be used for a quick introduction, but nothing deeper ...

Graphing Sea-Level Trends part of CLEAN Collection

Students use long term sea-level rise data set to create models and compare short-term trends to long-term trends. They then determine whether sea-level rise is occurring based on the data.

Lessons in Sea-Level Rise part of CLEAN Collection

This activity allows students to examine graphs of sea level rise data as well as global temperature data. They calculate amounts and rates of sea level rise for various time periods and answer ...

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 ...

Oceans and Atmosphere Example part of CLEAN Collection

This unit allows students to investigate past changes in Earth's climate. Students first explore relationships in climate data such as temperature, solar radiation, carbon dioxide, and ...

Arctic Climate Feedbacks part of CLEAN Collection

This video uses film of the Arctic and Arctic researchers as well as animations to discuss feedbacks in the Arctic climate system related to sea ice, the ocean, and clouds. It explains concepts such ...

Windy part of CLEAN Collection

This is a full color, worldwide, animated weather map using GIS interface showing current and projected wind and other weather conditions for any location in the world. Data can be viewed at ...
