The sediment in Lake El'gygytgyn, (pronounced EL-ge-GIT-gin) located in NE Siberia, holds one of the longest records of climate change anywhere in the continental Arctic. How does sediment (clay and mud) tell us something about past climate? Proxy data! By studying the microfossils of diatoms and pollen in the sediment, we can re-construct the lake environment millions of
In this activity students learn about varves, annual sediment layers found in lakes. Students will analyze authentic varve data from New England in order to correlate data from three different geographic locations .
Objective
Students will analyze authentic varve sediment data and create a graph of varve thickness. Students will use their results to make inferences about
This activity is designed to make a connection between a group of scientists and the students.
Objective
Students will learn that scientists are people too.
Preparation
The teacher will need to contact a group of scientists to make sure they would like to participate in the project and to explain to them the goals of the
