The Core Case Study in Chapter 1 of your textbook discussed how biomimicry was used to develop a sticky, toxin-free "gecko tape" that could replace toxin-containing glues and tapes. Develop a testable hypothesis to compare the functional effectiveness of gecko tape versus a commonly known tape. Along with your hypothesis, please provide a couple-sentence description of how you could test your hypothesis. Remember, a hypothesis must be measurable and specific. (Hint: there are many types of tape - choose one. We already know that the gecko tape is toxin-free, so we are not testing that. You need to test how well it works compared to another type of tape.)

Answer 1

Step-by-step explanation:

Hypothesis: The gecko tape will exhibit stronger adhesive properties and superior sticking ability compared to regular duct tape.

To test this hypothesis, a possible experimental setup could involve the following steps:

1. Materials: Gather the gecko tape and the regular duct tape as the comparison tape.

2. Test Surface: Prepare a clean and smooth surface, such as a glass or metal panel, to which the tapes can be applied.

3. Application Procedure: Cut equal-sized strips of gecko tape and duct tape. Apply one strip of each tape to the test surface with the same pressure and technique.

4. Adhesive Strength Measurement: Use a force gauge or a testing device to measure the force required to remove each tape from the test surface. Repeat this process multiple times to ensure accuracy.

5. Data Collection: Record and compare the adhesive strength values (force required to remove the tapes) for the gecko tape and the duct tape.

6. Statistical Analysis: Use appropriate statistical methods to analyze the data and determine if there is a significant difference in adhesive strength between the two tapes.

7. Conclusion: Based on the results, evaluate the hypothesis by determining whether the gecko tape demonstrates superior sticking ability compared to the regular duct tape.

By comparing the adhesive strength of the gecko tape and the regular duct tape, this experiment aims to provide measurable and specific evidence to support or refute the hypothesis regarding the functional effectiveness of the gecko tape.
