Observe Like a Phenologist: Tracking Nature’s Patterns Over Time
Lesson Plan by Susan Bartol
3x 45-60
minutes
Students explore observation as a foundational scientific practice by engaging in outdoor data collection inspired by phenologist Dallas Hudson from Chapter 7 of the documentary film, Observer. Through repeated observation, students begin to notice patterns in living and non-living components of their local environment and consider how scientists use data over time to understand change.
Free for educators! Inspiring documentary film that explores the power of observation—in science, art, and everyday life—to transform how we see the world.

How can I use this chapter in an interdisciplinary way?

This is a 3-day lesson plan consisting of:
Subject Areas: Biology/Life Science
Prior Knowledge: All animals need food in order to live and grow. They obtain their food from plants or from other animals. Plants need water and light to live and grow. (K-LS1-1); Plants depend on water and light to grow. (2-LS2-1); There are many different kinds of living things in any area, and they exist in different places on land and in water. (2-LS4-1)
Learning Objectives: Students will be able to...

The goal for this video + reflection activity is to reframe what counts as science.
Hand out the worksheet Observer Chapter 7: Student Viewing Guide to each student.
Prompt students with the “Before” questions:
Screen Chapter 7 (or clip from it). You may have to stop periodically so that students can answer the questions under “During the film” section of the Viewing Guide.
Have students reflect on and answer the “After the film” questions in the Viewing Guide.
Students participate as citizen scientists, using the Phenology Scavenger Hunt worksheet to record outdoor observations of their local environment. The goal for this activity is to get students to observe closely and collect real-world data.
What to look for during this activity:
Have students record their initial observations using the Northeast Phenology Scavenger Hunt worksheet or your own adapted Scavenger Hunt worksheet.
The goal is to have students make meaning from their observations and connect to scientific ideas about patterns, evidence, and repeated observation. The teacher will document observations made throughout the year in a spreadsheet.
What you look for during this activity:
Same Spot for a Year - visit the same spot on your school grounds over the course of the year. Document your observations in a Phenology Wheel.
Journals - for every outing take your phenology journal and record your observations using sketches and/or words. What connections can you make between the things you observe?
Sense of Place/Social Studies Connection - Research the Indigenous people of your area. Who are they? How did they use the land? What species were there at that time? Are these species still present? If not, which ones were lost? What are some possible explanations to why? How can we communicate what is here now with future generations?
