In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice. Learners create a chart, calculate population fluctuation for each transitional stage of sea turtles' lives, and graph the population at each stage. Learners investigate different factors including migration and human fishing that affect the size of the sea turtle population. Relates to the linked video, DragonflyTV GPS: Sea Turtles.
