Pollen Tracks

In this activity (on pages 30-36), learners simulate a dig for ancient pollen, to experience how paleobotanists study fossilized pollen in rocks to learn about early geological and climatological events on earth. Learners search in a "dig site" to find rocks, then carefully extract "seeds" from the imitation rocks (which must be made ahead of time). They record their data to understand the process scientists use in understanding the ancient earth.
