1. Science Project Preparation Practice

2. Directions: Select just two of the five problems that follow to write a statement of the problem, form a hypothesis, and write a detailed description on how you would test your hypothesis. First read the EXAMPLE on crickets that has been completed for you to get an idea on how to complete the two you select.

3. EXAMPLE: Do crickets chirp more in cold or warm temperatures? 1.Statement of the problem: Does temperature affect how much a cricket chirps? 2.Form a Hypothesis: I think that crickets will chirp more on dark warm nights, and less on dark cool nights. 3.Test the Hypothesis: Set up three containers each with a thermometer and a cricket. Each should be at a different temperature, but not too extreme. I will then count the number of chirps for each cricket for a period of 15 minutes.
