3. The Scientific Method

4. 1. Do Research -Background Information

5. 2. Asking a Question or State the Problem
What conditions are ideal for the growth of radish plants?
(Weather: hot, cold, rainy, dry, type of water, dark, high light)
Will radish ___________ in tap water or salt water?

6. 3. Form a Hypothesis
State which type of water will cause the plant to grow the fastest. Write your hypothesis as an “If, then” statement.
Write your own hypothesis:
Starter: If ______________ then___________________________
