With advances in technology and access to remote locations across the globe, scientists are rediscovering species that were once thought to have disappeared or thought to be extinct.

There are many variations of this exercise to have students generate the plot to the left, but I follow the Carbon Dioxide Exercise from the SERC website, where "Students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years.

An image is a powerful tool for Earth and space science instruction.  An image can capture a feature, a process, and/or an event and allow us to bring that snapshot to our students.  Although images may be used throughout a class period, an image can be used at the very beginning of a class to engage students and direct classroom discussion for the day.

We invite you to contribute to our collection of examples of how you utilize an “image of the day.”

I came across this exercise on the Project Exploration website and have used it as an in-class exercise for a course I teach on Dinosaurs.  My goals are to get students to think about what is involved in preparing and carrying out a field expedition, as well as to engage students in a basic quantitative exercise.  I like to expose my students to the process of science, and in this case, what it takes to think about and prepare for an expedition in the desert.
