Lesson Overview
How Echoes, Sonar, and Echolocation Work
Sound waves travel in all directions and can bounce off surfaces, creating echoes. Scientists use this property in sonar technology to measure distances underwater. The lesson introduces reflected sound waves, explains sonar, and shows how animals like bats, whales, and dolphins use echolocation to navigate and locate objects.
The five-page lesson pairs a reading passage covering echoes, sonar, echolocation, and the Doppler Effect with 10 comprehension questions and a full answer key.
How to Use This Lesson
1. Read the lesson passage together or have students read silently (pages 1–2). Discuss echo examples students have experienced.
2. Review sonar and echolocation with examples from the text. Connect the Doppler Effect to everyday sounds like approaching vehicles.
3. Assign the 10 comprehension questions (page 3) independently or in pairs. Review answers using the key on page 5.
