Students will count the fronds of duckweed for nine days to observe the growth phase. Students will need one class period to start the experiment and one day for the final work and 15 minutes per day between start and finish.

Before the Activity

Students will need one day to set up the experiment.

During the Activity

Students will spend 15 minutes a day for nine days counting the fronds of the duckweed plant. On day nine, the students will use their TI-Nspire to perform a regression analysis.

After the Activity

Extension: Students research the duckweed plant.
