How to Analyze Migration Data

How do scientists analyze migration data? They study the data they've collected, organized, and graphed. They look for patterns, make predictions, formulate hypotheses, ask questions, make comparisons, and share discoveries. Guide your students in taking the same steps that scientists take!

Here's how:
Use the Summarize and Analyze Chart to help students learn how to examine the data they collect and graph. This open-ended handout can be used in different ways. For example:

  • One week, look at the migration data to find patterns and make predictions.
  • Another week, make comparisons and pose possible explanations for differences noticed in the data.

Explore the sample sentence starters for ways to guide and support students' learning. Throughout the season, migration updates will include prompts and questions that will also help students learn how to analyze the data they collect and graph.
