Lesson Sequence 1: Overview
Total Time: 1 hour of instruction
Lesson Sequence 1 kicks off the Life Science Module with an anchoring phenomenon--a puzzling or engaging situation that creates a "need to know" for students. The anchoring phenomenon for this Life Science Module is a photo tour of a North American forest ecosystem. This makes the students wonder: Is this a healthy ecosystem? What makes this ecosystem healthy or not healthy? Students share their initial thinking on these questions in a Scientists Meeting.
Long-Term Learning Addressed (Based on NGSS)
Develop an argument that the flow of matter and energy among the sun, plants, and animals indicates the health of an ecosystem. (Based on NGSS 5-LS2-1)
Because the purpose of this lesson sequence is to launch the module and build student engagement, it does not yet explicitly teach any of the Science and Engineering Practices, Crosscutting Concepts, or Disciplinary Core Ideas. See Teaching Notes.
Lesson Sequence Learning Target
- I can make observations and participate in a Scientists Meeting to share my ideas about the health of an ecosystem.
Ongoing Assessment
- Student science notebook: Anchoring Phenomenon entry
- Scientists Meeting: Gathering Ideas
Agenda
In Advance
- Read each section and complete the Preparing to Teach: Self-Coaching Guide.
- Refer to the Key Features of the Life Science Modules in the introduction for more information on Scientists Meetings.
- Establish expectations of behavior during group discussions and pair work.
- Prepare:
- Student science notebooks; consider where students will store them in the classroom so they will be readily available
- Teacher science notebook
- Image of professional science notebook
- Norms of a Scientists Meeting anchor chart (see supporting materials)
- Assessing the Health of an Ecosystem slideshow, or print out photos from the Assessing the Health of an Ecosystem slideshow in color (see supporting materials)
- Post: Life Science Module guiding question and lesson sequence learning targets.
Optional extensions:
- Personalizing My Notebook: Give students time to decorate their science notebooks or attach an additional cover. For suggestions see the video: Teacher Perspectives: The Value of Science Notebooking.
- U.S. Parks Virtual Tours: Show students additional ecosystems by exploring the Google Street View images here or here.
- Video of Olympic National Park: Students could view this wordless video entitled "Smell of Cedars Steeped in Rain" that features scenes around the park. Students could note the abiotic and biotic features.
Vocabulary
ecosystem = the living and nonliving things in an area that interact

Opening
Section 1: Opening | Preparing to Teach: Self-Coaching Guide |
---|---|
A. Reviewing Learning Targets and Launching Science Notebooks (15 minutes)
"What do you think this word means?" (Responses will vary.) "Where have you heard this word before?" (Responses will vary.) "What does each part of the word mean?" (eco = environment; system = parts working together)
"What is one thing you notice about the information in the professional science notebook entries?" (Responses will vary, but may include that these entries have observations written in words and pictures, they use scientific vocabulary, and they include basic information, such as where the information was collected.)
|
(1) What experience do my students have with the vocabulary word ecosystem? (Students may have learned about ecosystems in earlier grade levels. They may have used language, possibly discussing a plant or animal's habitat, environment, area, or surroundings.) (2) Have I used a student notebook in my classroom before? How is this similar to or different from what I've done before? Do I have a student model that would be useful to students? |

Section 1: Obtaining InformationA. Anchoring Phenomenon: Recording Observations about Ecosystems (15 minutes)
|
(1) After previewing the images in the slideshow, at which points will I stop and ask the students to turn and talk? (2) What questions will I ask to stimulate closer observations? |
B. Scientists Meeting: Gathering Ideas (30 minutes)
"What are your thoughts and wonders about ecosystems so far?" (Responses will vary.) "What does it mean for an ecosystem to be 'healthy'?" (Responses will vary.) "What do you think about the health of the ecosystem that we just viewed?" (Responses will vary, but may include: The ecosystem is healthy, unhealthy, or a combination.)
"These logs are rotting and decaying. Is this healthy or not healthy or both? How do you know?" (Responses will vary. Do not correct student thinking at this time.)
"This bear is eating something. Where did this food come from? Where will the energy that the bear gets from eating this food go?" (Responses will vary. Do not correct student thinking at this time.)
"This deer has reproduced. Is that an indication of being healthy or not healthy or both? How do you know?" (Responses will vary. Do not correct student thinking at this time.) "What should we measure to assess health?" (the plants and animals, air and water conditions, the way the needs of plants and animals are met, the cycles of the system, etc.)
"What did you see in the slideshow that makes you think that?" "What have you seen, heard, or read that makes you think that?" "What experience have you had that supports that idea?"
"Do others agree or disagree? Why?" "Can someone paraphrase what Student A said?"
"Did someone have something similar to what X observed? How was it the same? How was it different?"
"What will we observe about the organisms in a healthy ecosystem?" (They are in balance; all of the organisms can get their needs met in a stable environment; there will be a diversity of organisms, including lots of producers (like plants) and some primary consumers and a few secondary consumers.) "What will we observe about the water, soil, and air?" (It is clean; water and air will cycle through organisms; the nutrients in the soil will be part of the cycle of matter.) "What will we observe about the whole system and how it works?" (All parts of the system will work together to keep the ecosystem stable.)
|
(1) How can I record the Scientists Meeting for students to listen to at the end of the module so they can track their learning about the health of an ecosystem? (2) A Scientists Meeting is different from a regular group discussion. What group norms will I emphasize? (3) What probing questions can I ask if students are struggling to engage in the meeting? (Consider questions that ask students to look closer like "Did you notice...? What else do you see?") (4) Do not correct student thinking about the health of the ecosystem at this time; the purpose of this conversation is to document students' current thinking. (5) My students may not have accurate background knowledge about energy. What additional questions can I ask to surface misconceptions? Consider:
Note: Students will likely not be able to articulate the answers to these questions. By the end of the module, they will have learned these concepts. I'm eliciting students' current thinking; I should not give them the answers at this time. (6) How much practice do my students have with self-evaluation? Will they need a more structured way to reflect on how well they kept the norms? |
