Rings of Life
Individuals analyze tree rings to determine the health of an ecosystem. They then look at otoliths of fish, hard calcium carbonate structures located behind the brain, in the same manner.

Who Will Melt First?
If the Greenland ice sheet melted, sea levels would rise by about 20 ft; if the Antarctic ice sheet melted, sea levels would rise by 200 ft. Scholars explore ice melting through the analysis of different ice samples, clean and dirty ice....

Is There Salt in a Glacier?
What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts.

Can Carbon Dioxide Act Like a Greenhouse Gas?
Ninety-seven percent of scientists who study climate agree that human activity is warming the planet. Learners explore carbon dioxide as a greenhouse gas, a gas causing this warming, through a hands-on experiment. Once complete, they...

Sea Ice Impact
The arctic seas contain currents that are both warm (with high salinity) and cold (relatively fresh water) that circulate throughout the year. Through discussion, a lab, and a web quest, participants explore the impacts of melting and...

Arctic Smorgasbord!
Two blooms of phytoplankton, instead of just one, now occur in the Arctic due to declining sea ice, which will have widespread effects on the marine life and climate. In small groups, participants build an Arctic food web with given...

What Can We Learn from Sediments?
Varve: a deposit of cyclical sediments that help scientists determine historical climates. Individuals analyze the topography of a region and then study varve datasets from the same area. Using this information, they determine the...

Down to the Deep Virtual Lab
At a depth of 3,000 m in the ocean, the pressure is 300 times that at sea level! In the activity, individuals predict what will happen to Styrofoam cups submerged 3,000 meters into the ocean. They then convert these units to soccer...

Polar Detectives: Using Ice Core Data to Decode Past Climate Mysteries
How does examining an ice core tell us about weather? Learners set up and explore fake ice cores made of sugar, salt, and ash to represent historical snowfall and volcanic eruptions. From their setups, scholars determine what caused the...
