Glacier Game

Glacier Game

Review the effects of retreating glaciers and increasing stream flows and erosion on river, coastal, and ocean ecosystems.

Changing Landscape

Changing Landscape

Changing Landscape asks students to analyze “repeat photographs” (taken from the same vantage point at different times) of Alaska glaciers to observe the effects of retreating glaciers on the landscape.

Arctic Sea Ice Data

Arctic Sea Ice Data

This 5-6 day investigation challenges students to think about how sea ice is changing and the effects of a warming climate on sea level in Alaska.

Density

Density

In this 7-9 day investigation, students are engaged in a variety of hands-on demonstrations and experiments that will help them to understand thermohaline circulation in the ocean. They begin with an introductory activity that helps them to review or arrive at a definition of density, then go on to demonstrate the effects of temperature and salinity on density and design their own experiment to simulate ocean mixing. They experiment further with hot and cold water as they consider the effects of tropical and polar climates on ocean currents, and end by writing conclusions to summarize their learning.

Waves in the Water

Waves in the Water

In this 7-10 day investigation, students develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on investigation. They demonstrate wave motion in containers, and create marigrams to show local tide data and to compare tide patterns from different parts of the world. They use their knowledge to consider whether waves or tides could account for the movement of the bath toys to their final locations.
