In preparation for an upcoming research project focused on a topic of their choice, students will practice corroborating information found in a variety of sources. This lesson can be done with sources from any topic, as long as there are multiple sources on the subject.
Classroom Teacher; Science Teacher
Students will corroborate information using a variety of sources.
Students will identify information within a variety of sources.
Students will compare found information to determine what information is supported by other findings.

Common Core State Standards
CCSS.ELA-LITERACY.RI.3.1 Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers.
CCSS.ELA-LITERACY.RI.3.7 Use information gained from illustrations (e.g., maps, photographs) and the words in a text to demonstrate understanding of the text (e.g., where, when, why, and how key events occur).

ESS3.B: Natural Hazards: A variety of natural hazards result from natural processes. Humans cannot eliminate natural hazards but can take steps to reduce their impacts. (3-ESS3-1)
Begin the lesson by asking students why they think it may be important to check to see if information is correct. Share with students that one way to check information they find from sources is to compare it with the information from other sources.
Ask students to gather information from the source using a note taking system that students are familiar with. Encourage students to put information in their own words as opposed to taking information directly from the text.
After 10-15 minutes, bring students together to categorize information. Ask students what type of information they found about hurricanes. Categories may include how they form, the damage they can do, or historical information about past hurricanes. Choose one of those categories for the next step.
Using three intersecting circles as a graphic organizer, ask students to share information they found from their source. As a student shares information, ask students who used the other two sources to share whether they found information that was the same or similar. Place the information on the organizer based on whether it was confirmed by the other sources or not.
If students seem comfortable triangulating data in this way, put them in groups of three, including one student who used each source, to do the same with a different category. This may also be done again as a whole class instead of in small groups.
Ask students what information is the most trustworthy based on how many times it has been confirmed. Ask how they could verify other information that was found in only one of these three sources.
This lesson may be used with any combination of three sources on a topic. Resources can be text-based or audiovisual. Sources can vary in difficulty for a variety of student abilities. Students may also self-select their sources or work in pairs or small groups.
Students fill out an exit slip responding to the question: "How can comparing the information found in several sources help you when you are learning more about a topic?"
