Objectives:
Investigate the remarkable physical adaptations of humpback whales, focusing on the unique tubercles found on their flippers. Discuss biomimicry and explore the potential implications of humpback whale adaptations in inspiring advancements in human technology.
*IMPORTANT NOTE* Remind students that they will be doing a research report about humpback whales and reporting it to the class in part 3 of this class series. Instruct students to do research using JW.ORG and other sources about humpback whales and write a report. They will bring this report to the final class.
Materials:
Visual aids (diagrams and images illustrating humpback whales and their tubercles)

- What Do Whales and Wind Turbines Have In Common?:
Exploring Humpback Whale Adaptations (10 minutes):
Introduce the concept of tubercles, specialized bumps found on the leading edge of humpback whale flippers, and explain their role in enhancing lift and minimizing drag during locomotion. Use visual aids and describe how tubercles create controlled turbulence, facilitating precise maneuvering and enhancing agility in the water.
Discuss the applications of humpback whale flipper design in human technology, such as improving the efficiency of aircraft wings, turbine blades, and wind turbine designs.
Activity/Discussion (15 minutes):
Organize a hands-on activity where students learn to draw humpback whales, using the resource linked here. Facilitate a group discussion about biomimicry and humpback whales, challenging them to think of other ways technology could benefit from imitating the ingenious design of the whale flipper.
How to Write a Report (5 minutes):
Briefly review how to write a report to prepare students for the final class in this series. Briefly summarize the points from the 4th Grade Reading & Writing – Writing a Report: Part 1 and the Reading & Writing – Writing a Report: Part 2 lessons.
Conclusion (3 minutes):
Summarize the key insights from the lesson, emphasizing the remarkable adaptations of humpback whales and their potential applications in inspiring innovations in human technology. Remind students to come the next class ready to present their completed research reports.
Assessment:
Assess student comprehension and engagement through active participation in discussions, completion of the hands-on activity, and thoughtful responses to reflection questions. Evaluate students’ ability to apply scientific concepts to real-world scenarios, including the potential implications of humpback whale adaptations for human technology, through discussion, quizzes, or activities.
