1. Forming Scientific Questions
From scientific questions to research projects

2. Tips on Asking Good Scientific Questions
Ask several questions about a topic
Eliminate questions that cannot be answered with DIRECT OBSERVATION or by GATHERING EVIDENCE
Break broad questions into smaller questions (that can be answered one at a time)
Write questions so they can be answered by an experiment.

3. 1. Some people work better in the morning, and other people work better in the afternoon.
2. Taking something that belongs to another person is wrong.
3. Snakes travel in pairs.
4. Animals behave in strange ways before an earthquake.
5. People shouldn’t use things unless they can be recycled.

4. 6. Basketball is a better sport than soccer.
7. You will remember best whatever you read just before you fall asleep.
8. Maria’s bike is faster than Charlie’s bike.
9. Each year when the weather gets cold, birds fly to warmer regions.
10. Trucks use more gasoline than cars.

5. Choose one of the scientific questions you identified and rewrite it to make it a better scientific question. State what kind of evidence you would need to collect to answer the question. How do you think a researcher could collect that evidence?

6. “Fact” Questions Example: “How many hermit crabs live under the rock?”
What data would you collect to answer this question?
What would your hypothesis be?
It’s hard to make one.
Guessing the number is like guessing the number of jelly beans in a jar.
May be able to guess how many crabs, but it won’t tell you anything about why there are so many or so few.

7. Let’s fix it:
“How many hermit crabs live under a rock?”

8. “Comparison” Questions
Example: “Are certain areas better for sea anemones than others?”
COMPARISON questions are GREAT!
This question is very broad with vague wording. Think about:
What determines where sea anemones are?
What are some examples of areas with different conditions important to sea anemones?

9. Let’s fix it: “Are certain areas better for sea anemones than others?”
Ideas:

10. “Why?” Questions
Example: “Why are there a lot of limpets in the intertidal ?”
Think about reasons for this pattern
What is the environment?
Think about a more specific question
Ideas:

11. “How?” Questions Example: “How do snails react to seastars?”
Think about the ways snails may react to seastars
Think about why they react that way (or not)
Ideas:
