1-2 Activity 6: Mapping Seed Sources


This activity introduces students to ongoing research into the genetics of loblolly pine. Because of variation between the eastern and western populations of native loblolly pines and the environments in which they grow, some families of pine grow faster than others and some resist drought better. Students are asked to graph survival and height data from six different families on three sites to determine which traits are associated with which population. Based on what they learn about forest genetics, students can project where trees with certain characteristics are likely to thrive in changing climatic conditions.

Teacher Comments

My students did well with this. It was a great review of different climates and how trees might respond to them.

I went over some of the graphing basics and assigned this activity as homework. We discussed it the next day. Students were able to extrapolate the data needed and to interpret their graphs.

We used our laptops to develop the graphs. Prior knowledge of the software will be needed for the teacher and the students. We took a couple days just getting a handle on our spreadsheet program. Once we had that under control, we moved quickly to the questions and answered the problem.

I had the students graph their data on large Post-it® note graph paper to make it more interesting to them and to showcase the data better when we analyzed it as a class.
