Lesson: Canine Compass?

As a class, list the five main human senses (touch, taste, smell, sight, hearing) and record them. Ask for examples of how each sense is used. How do senses help humans survive? How do senses help other animals survive? Do some animals rely on different senses than humans? What are they? (Some animals, like bees, can see light that humans can’t; animals may hear sounds we can’t; animals may sense vibrations; animals may detect electrical [sharks] or magnetic [birds] fields, etc.)

Read the article aloud as a class. As you read, pause and note how the researchers used scientific processes even though they were not in a controlled lab setting. Ask questions such as: What was the research question? How did they test their ideas? What data did they collect? What did they conclude? After reading, ask the class for other possible explanations for the dogs’ behavior and what additional questions the study raises.

Distribute the “Investigate It! Canine Compass?” skills sheet and have students use it to complete the questions at the end of the article. Discuss why students felt there is or isn’t enough evidence to support the claim that dogs can sense magnetic fields. Discuss what additional evidence would strengthen the scientists’ case and what they have planned for further investigation.

Have students complete the “Check for Understanding” assessment. Then distribute the “Special Senses” skills sheet and have students complete the activity. Create small groups for students to share ideas and provide feedback. Remind them to use sentence starters like: One thing you did well is . . .; One thing you could improve is . . . Have students use the feedback to revise their plans. Optional: Have students make a video to pitch their proposed scientific study for funding. Discuss how scientists may have to secure funding for research.

As a class, examine the diagram showing Earth’s magnetic field. Ask students to describe their observations about the diagram. Then distribute “Magnetic Shield” for students to complete.
