Question

Lengthening the string of the pendulum increases the time it takes the ball to make one complete period.

What correction would you have the student make to the hypothesis?
A) Turn it into an "if/then" statement.
B) Add the word "will" in the middle after the word "pendulum".
C) Switch the order of the sentence so that the phrase about the period comes first, & the phrase about the string's length is last.
D) No corrections are needed.

Answer 1

The student's hypothesis should be corrected to an "if/then" statement.

Step-by-step explanation:

The correct answer is A) Turn it into an "if/then" statement.

The student's hypothesis should be corrected to an "if/then" statement so it clearly states the cause and effect relationship. By framing the hypothesis as an "if/then" statement, the student can accurately predict the effect of lengthening the string on the time it takes the ball to make one complete period.

For example, the corrected hypothesis could be: "If the length of the string is lengthened, then the time it takes the ball to make one complete period will increase."
