Students investigate how melting glacial ice affects sea levels by conducting an experiment comparing land and sea ice melt. They analyze predictions, record observations, and discuss the implications of rising sea levels, including regional variations and climate impacts.
Students investigate how warming seawater affects sea levels by measuring water expansion when heated. They analyze their results, discuss thermal expansion’s role in sea level rise, and explore the broader impacts of melting Arctic sea ice on climate and ecosystems.
Students investigate whether melting Arctic sea ice affects sea levels by observing an ice cube melting in a cup of water. They record predictions, analyze results, and discuss how ice displacement explains why sea ice melt does not raise sea levels, with extensions exploring water density differences.
Review the effects of retreating glaciers and increasing stream flows and erosion on river, coastal, and ocean ecosystems.
Students construct a mini Secchi disk to investigate transparency and the effects of increased turbidity from the increased flows as glaciers melt on aquatic and marine ecosystems.
