Answer :

Certainly! An experiment is a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact. In this case, the example of an experiment is: B. Testing the effectiveness of a new hair product by allowing one group to use it and comparing results against a group that doesn't use it. This scenario involves a controlled study where one group is exposed to the new hair product while another group serves as a control group that does not use the product. By comparing the results between the two groups, researchers can determine the effectiveness of the product. This setup allows for the observation of any differences in outcomes, helping to draw conclusions about the product's impact.
