Paleoclimate Reconstruction Lab

Type of Resource



In this activity, students reconstruct past climates using lake varves as a proxy to interpret long-term climate patterns. Students use data from sediment cores to understand annual sediment deposition and how it relates to weather and climate patterns.

Performance Expectations

HS-ESS2-2   Analyze geoscience data to make the claim that one change to Earth's surface can create feedbacks that cause changes to other Earth systems.

MS-ESS2-2   Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.
