This is a short experiment to demonstrate the concept of thermal expansion of water when heated, as an analogy to thermal expansion of oceans due to global warming.

This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

In this short but effective demonstration/experiment, students investigate how thermal expansion of water might affect sea level.
