Question

In the following table, label each statement as true (T) or false (F). If the statement is false, rewrite it so that it is true.

Statement
T or F
Rewritten Statement

1) Scientists cannot change a hypothesis before beginning their experiment.

2) A hypothesis must be testable to be valid.

3) The steps of the scientific method must be performed in order, or the test is not valid.

4) Conclusions must be based on data rather than beliefs.

Answer 1

1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?

2) False. A hypothesis can’t be “valid” because it’s literally a prediction.

3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS

4) True. The conclusion must be based on data because it’s the observation that was seen.

Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)
