Question

a scientist designs and conducts an experiment to see if a new skin cream heals burns faster than an existing cream. which of the following should the scientist do next to make sure the investigation and results are valid? share the results right away with other scientists conduct many trials of the same experiment design and conduct a new experiment to test a different cream design and conduct a new experiment to test more than one variable

Explanation:

To ensure valid results in a scientific experiment, multiple trials of the same experiment are needed to account for random errors and variability. Sharing results prematurely may lead to misinterpretation without proper validation. Testing a different cream or multiple - variables is a different experiment and not relevant to validating the current one.

Answer:

conduct many trials of the same experiment
