Lesson 31: Synthesizing Information from Sources
Content
Students will synthesize ideas from multiple sources into a clear paragraph that answers an inquiry question.
Language
Students will use signal phrases, comparison transitions, and complex sentences to connect ideas across multiple sources.
Foundational Skills
Students will accurately use common signal phrases and transitions when combining ideas from multiple sources.
How do different disciplines and traditions, including scientific inquiry and cultural knowledge, help us understand our relationship to the natural world?
Knowledge-Building:
Students move from paraphrased notes to synthesis by showing how multiple sources connect, compare, and build on each other.
Enduring Understanding:
When knowledge is shared across generations and worldviews, it can restore balance between people and the planet.
Future Lessons:
In Lesson 32, students will continue to work on writing notes about their sources and/or drafting synthesis paragraphs. In Lesson 36, students begin to use their research to begin the drafting of their presentation for the Performance Task.
Unit Performance Task:
Students must synthesize multiple credible sources, including differing perspectives, in their final research presentation.

Quick Write
Have students take out their 3-Column Charts with their research notes from Lesson 30.
Say these Directions: Look across your notes from 2–3 sources. Think silently and jot down one idea that appears in more than one source. Turn to your partner and explain what the repeated idea is and why it matters for your inquiry question.
What is one idea that appears in more than one source, and why is it important?
More than one source explains that controlled burning reduces fuel buildup in oak woodlands. This matters because it shows a key way fire management restores ecological balance, which connects directly to my inquiry question.
Say: Today, you will look for repeated ideas across sources and discuss those ideas in synthesis paragraphs.
Sentence Combining with Signal Phrases & Transitions
Introduce to students the concept of sentence combining using signal phrases and transitions. Remind students that they learned about sentence combining as a writing strategy in Unit 8.1.
Say: A signal phrase names the source of an idea. A transition shows how one source connects to another. When we synthesize ideas, we combine ideas to show relationships.
Say: I will model how to combine notes using our model topic: fire management. If I list notes, my writing sounds disconnected. Instead, I name the source, add a second source, and show how the ideas connect.
Display the model notes and synthesis response.
Separate Research Notes
Note A: Karuk fire practitioners use seasonal observation and plant knowledge to decide when burns are safe.
Note B: Forest scientists measure fuel moisture and fire behavior to determine safe burn conditions.
Model Combined Response
According to Karuk fire practitioners, cultural burning depends on seasonal observation and knowledge of plants. Similarly, forest research shows that measuring fuel moisture helps identify safe burn conditions. While cultural fire knowledge emphasizes seasonal cues, Western science focuses on quantified fire conditions.
Say: Let’s look at the overall structure of the sentence combining model.
Model Structure
Part | Function |
|---|---|
According to Karuk fire practitioners | signal phrase (names source) |
Cultural burning depends on . . . | idea from Source 1 |
Similarly, forest research shows . . . | transition + idea from Source 2 |
While ___, ___ | comparison + analysis |
Say these Directions: Work with a partner to combine each of the notes into a 2–3-sentence synthesis paragraph. Use at least one signal phrase and one comparison transition.
Display the two research notes.
Note A: Yurok fire practitioners burn patches regularly so brush does not build up around oak trees. Note B: Ecologists report that frequent low-intensity fire reduces fuel loads and lowers the risk of severe wildfire.
Provide time for students to work with a partner to create a synthesis paragraph using sentence combining.
According to Yurok fire practitioners, regular cultural burns keep brush from building up around oak trees. Similarly, ecologists report that frequent low-intensity fire reduces fuel loads and lowers the risk of severe wildfire. Together, these sources show that repeated burning can prevent more destructive wildfires.

When students refer to Indigenous knowledge sources, push for specific attribution when possible. Encourage phrases like “According to the Karuk Tribe Department of Natural Resources . . .” instead of broad statements like “Indigenous people say . . .” |
Students will now synthesize their ideas from the notes that they have taken across their research. From this synthesis, students will learn how to create a paragraph that combines information from multiple sources.
Say these Directions: Today, you will use your overarching inquiry question from your research and choose 2–3 sources that help answer it. Then you will review those sources, looking for common ideas. From there, you will write a synthesis paragraph that discusses the common ideas across the selected sources.
Display the following research inquiry question.
Model Inquiry Question: How can fire management restore balance in California oak woodlands?
Say: I’m going to use this inquiry question to look across my notes and determine if there are commonalities or patterns I’m noticing across my sources. For example, I notice the following.
Display notes from Sources 1 and 2.
Source 1: According to the Karuk Tribe Department of Natural Resources, controlled burns are timed with seasonal signs and reduce excess brush before severe fire conditions build.
Source 2: Similarly, a forest ecology study explains that frequent low-intensity fire lowers fuel loads and helps oak woodlands recover.
Say: I notice that both of these research notes are talking about reducing severe fires through controlled burns. I can put these ideas together by comparing them.
Display the synthesis paragraph.
While the first source emphasizes place-based seasonal observation, the second uses fire-behavior data; together they show that repeated fire can protect the woodland system. Controlled burning supports reciprocity by helping both people and ecosystems thrive.
Ask: How did I combine ideas across sources? How did I use my notes to combine those ideas?
You took ideas that are similar and compared them to answer your inquiry question about controlled burns or fire management.
Remind students that a strong synthesis paragraph must name sources clearly, include evidence, and explain what the comparison shows.
Transition students into synthesizing ideas across their sources. Display the following process for students to follow:
Synthesizing Ideas Process
Read through your research notes using your research inquiry question.
Look for patterns and commonalities between sources.
Draw connections between those sources by combining the ideas in sentences.
Create a synthesis paragraph answering your research inquiry question with evidence from at least 2–3 sources.
Display the following synthesis paragraph to use to support students.
Model Synthesis Paragraph:
Fire management restores balance in California oak woodlands because multiple sources show that regular low-intensity burning protects the natural system from more destructive fires. According to the Karuk Tribe Department of Natural Resources, cultural burns are guided by seasonal observations and reduce brush before dangerous conditions build. Similarly, a forest ecology study explains that repeated low-intensity fire lowers fuel loads and supports recovery. While the tribal source emphasizes place-based observation, the scientific source focuses on measured data. Together, these perspectives suggest that restoration is strongest when both knowledge systems are used for fire management.
Remind students that their draft paragraphs need only include 2–3 sources with a common idea that can answer their research inquiry question. Also, students are only expected to draft one synthesis paragraph using several of their sources, not the entirety of their sources.
Say these Directions: Draft your synthesis paragraph using 2–3 sources that address a common idea in relation to your overarching research question.
Provide students with a confidence continuum (i.e., 1–5). As needed, model how to demonstrate a level of confidence using the continuum.

Students reflect on their research synthesis in a Quick Write response.
Ask: How did using signal phrases and transitions help you combine ideas from your sources? What was still challenging? What changes, if any, do you need to make to your research process, and what are your next steps for the next research lesson?
Signal phrases helped me clarify which ideas came from which sources so my paragraph did not sound confusing. The transition helped me compare a tribal fisheries source with a science article instead of listing them separately. One challenge was writing the analysis sentence after the evidence because I sometimes stopped too early. My next step is to review more sources and mark where I can compare or connect ideas before drafting again.
Students read their independent reading book for 20 minutes and complete a reading log entry.
Read your independent reading book for 20 minutes. In your reading log, record the date and pages you read, write 1–2 sentences about what happened or what you learned, and respond to this week’s prompt using evidence from the text.
