Explanation:

Question 1

The first step of the scientific method is making an observation, not forming a hypothesis. So the statement is false. The underlined word "Forming a hypothesis" should be replaced with "Making an observation".

A scientific law describes a phenomenon in nature, while a scientific theory explains it. So the statement is true as it correctly differentiates them (law describes, theory explains).

To test a hypothesis (make it testable), scientists design experiments to support or disprove it. The statement is true as this is a key part of the scientific method.

Answer:

False; replace "Forming a hypothesis" with "Making an observation"
