1. Start with a Riddle
Share the following clues one at a time, encouraging students to
identify the animal you are describing: No
hearts...No lungs...Takes in
oxygen. After students share responses, reveal the

2. Assess Prior Knowledge
- When do you see earthworms in your backyard?
- What signs help us predict when we'll see the first earthworm of spring?
- How do you think the arrival of earthworms and the arrival of returning robins are related?
3. Make Predictions
Preview images in the photo gallery. Post the question: How is robin migration related to the return of earthworms in the spring? Have students share predictions and questions based on details they see in the photos.
