## Module 4 Test Your Hypothesis

### Lab

Obtain a piece of PTC paper, along with a piece of control paper. Place a strip of control paper on the center of your tongue for a few seconds. (This way you know what just the paper tastes like.) Then, put a strip of PTC paper on the center of your tongue for a few seconds. How does it taste? Like the control paper? Slightly bitter? Very bitter? This will tell you if you’re a nontaster, weak taster, or strong taster. And, it lets you evaluate whether your hypothesis was supported by the new evidence, or rejected.

Submit a statement that includes your hypothesis, how the PTC paper tasted to you, and whether your hypothesis was supported or rejected.

### Objective

- Test a hypothesis based on the results of gel electrophoresis.
