Create a hypothesis to answer this question.
NOBS 2

6. Scientific Method-200
If there is an increased amount of acid rain in an ecosystem, then the population of frogs will decrease.
NOBS 2A

7. Scientific Method 300
Do wounds heal faster when they are covered by Band-Aids?
Write a hypothesis to answer the question above.
NOBS 3

8. Scientific Method- 300
If a wound is covered in a band-aid, then the amount of time it takes the wound to heal will decrease.
NOBS 3A

9. Scientific Method- 400
You and your friends were studying lists of spelling words and vocabulary words. It seemed like everyone could easily remember the first word on the list and the fifteenth word on the list. It seemed very hard to remember the words in the middle of the list.
Write a question and a hypothesis regarding the scenario.
NOBS 4

10. Scientific Method- 400 Question/Problem: Hypothesis:
Why is it difficult to remember the words in the middle of a list?
Why is it easy to memorize the first and last word of a list?
Hypothesis:
If a word is in the middle of a list, it is more difficult to remember because the words have not been stored into your long term memory nor are they stored in your short term memory.
If a word is listed at the beginning or end of a list, then it is easy to memorize because the first word is stored into your long term memory and the last word is still in your short term memory.
NOBS 4A

11. Scientific Method- 500
List the general steps of the scientific method.
NOBS 5

12. Scientific Method- 500 Question Hypothesis Experiment Analyze
