You ask a question about something that yo observe: How. What, When, Who, Which, Why, or Where?
Once you have a chosen topic of interest, you will need to create a related scienti
question. Without a good question, your whole scientific investigation will be much harder
not impossible! It is important to select a question that is going to be interesting to work
and that is specific enough to allow you to find the answer with a simple experiment
Directions: Read and analyze the experimental scenario carefully. Write the letter of the
correct answer on a separate sheet of paper.
Johnny divided 30 unripe bananas evenly among six paper bags and sealed the bags.
He poked 20 small holes in three of the bags and left the other three without holes. He
kept the bags at room temperature for three days. Then, Johnny opened the bags and
counted the number of brown spots on bananas from bags with holes to the average
number of brown spots on bananas from bags without holes.
1. Which experimental question that best describes Johnny's experiment?
A Do bananas develop more brown spots when they are kept at room temperature
compared to in a cold refrigerator?
B. Do bananas develop more brown spots if they are kept in bags with holes
compared to bags without holes
