what other ways can scientists answer questions if they coant do an experiment?

Answer 1

observation - e.g. observing behavior of an organism; cataloging the numbers of a species in an area;

measurement - e.g. weighing the growth of a infant; measuring the height of a plant; determinine the length of a whale

reasoning - e.g. taking data produced by other scientists and finding an alternate theory that explains it; reconciling two previously incompatible theories in a novel way

Answer 2

By postulating a plausible theoretical explanation, and then applying what is know about an earlier condition or situation to see if the postulation predicts the observable current condition. For instance, we can't really "prove" that a river as small as the Colorado could cut the Grand Canyon, the experiment would take too long! But we can create small-scale erosion models, think aboout what the walls of the Grand Canyon SHOULD look like if they really were created by hundreds of thousands of years of erosion, and then, if the Grand Canyon matches our model, we can safely conclude that tha's how it did, in fact, arise.

Excellent question!

Answer 3

They can hypothesize as to what the answer is, but they will never be able to get a scientifically sound answer without experimenting in some way.

Answer 4

By using simulation. Based on the data (already known) such as properties, strength, force, weather, environment,etc.
