    1. 1 NanoLeap: Exploring the Mystery of the Gecko Physical Science Lesson 1 How Can a Gecko Walk on a Ceiling? NanoSize Me Tricky Feet Videos: http://www.mcrel.org/nanoleap/multimedia/index.asp

    2. 2 Data Table

    3. 3 Observations Make observations about the following images.

    4. 4 Interpretations Make interpretations about how the organism is “sticking” or “adhering” to a surface.

    5. 5 Questions What do the images have in common? What do you observe about the surfaces and textures in these images? What might you interpret about the surfaces on which you observed the gecko climbing? 4. What additional information do you need to know in order to understand what makes a gecko adhere to surfaces?

    6. 6 More Questions 5. What are some possible methods for the gecko to adhere to a surface? 6. Describe how you made your observations in today’s lesson: a. What tools did you use? b. Were your observations at the visible or invisible scale? c. What is the dominant force at this visible scale? 7. What variables affect the force between the animal and the surface?

    7. 7 Making Connections Describe one or two ideas that you learned during this lesson. How do you think the gecko sticks to the ceiling? What should we explore next?
