Population Estimates: Bringing Math and Science Together

Project EXTREMES lessons were written to be stand alone lessons, but this activity may be used prior to a field study to provide students with practice in estimating or used in a unit on ecosystems.

During this activity students will learn how to estimate population size using two techniques, density extrapolation and the mark-recapture method.

A Changing Arctic Ecosystem

This storyline unit consists of 8 lessons, each tied to NGSS life science standards

The Arctic is warming more rapidly than anywhere else on Earth. One consequence of a warming Arctic is a dramatic decline in sea ice, an important habitat for many Arctic plants and animals. In this unit students will engage with 360° virtual reality tours, hands-on labs, and authentic Arctic datasets as they gather evidence to construct explanatory models for the unit driving question, "How might the decline in sea ice affect Arctic organisms large and small?"
