Scientists are doing an experiment to see which brand of 30 SPF sunscreen works best. They applied the different brands of sunscreen to an object that measures the amount of UV rays (sunlight) that gets through the sunscreen. The scientists will use the data to compile a list of the best sunscreen brands. They also run a tests with no sunscreen. Why is it important that the scientist gather empirical data in order to make their decisions?

• A. Data allows scientific theories and laws to form.

• B. Data provides evidence to conclude their observations and hypothesis.

• C. Data allows the scientists to gain all credit for experiments taking place.

• D. Data ensures that scientists are following the scientific method in the proper order.

Why is scientific argumentation important when evaluating a scientific claim?

• It helps to critically examine the evidence and reasoning to support or refute the claim.

• It allows scientists to prove their opinions are correct without the need for evidence.

• It encourages accepting claims based on authority rather than data.

• It simplifies complex ideas by ignoring contradictory information.
