Abstract: This activity gives students a chance to build a differential or difference equation model similar to standard textbook mixing problems.The activity uses tangible objects ("fish") and a student-designed restocking and fishing plan for a lake. The mixture is of two species of fish; one is the only species currently in the lake and the other is introduced via restocking. Students generate data via a brief simulation and then conjecture forms of a differential or difference equation model.
