Students learn about plant response to light by setting up simple investigations in the classroom.
Students learn what to look for during budburst by observing variations in timing and appearance of leaves of different local plant species.
Students observe and classify local plants based on their patterns of change other than growth.
Students will analyze visualizations and graphs that show the annual cycle of plant growth and decline.
Students participate in a preparatory activity that will help them identify green-up progression in their local plants and this activity also introduces the idea of spatial scale related to plant observations.
