In which step of the scientific method do we talk to experts, read books, and look online for what work has already been done?

Which step of the scientific method provides graphs and charts to process the information (numbers, etc.) we've gathered?

Gianna wants to test which brand of popcorn pops the most kernels. She picked a store brand, Orville Redenbacher, and PopSecret. All three bags started with the same number of kernels. She popped each for 3 minutes in the same microwave, and then counted the number of kernels left over. What is her independent variable?

What do you do with your data after you go through your experiment?

Fish hatcheries are an enclosed environment used to raise a large number of fish. A fish biologist wondered if fish raised in hatcheries would be able to survive in a wild environment. The biologist thought that fish raised in hatcheries lost their fear of predators.

To test the idea, he placed 15 hatchery trout and 15 wild trout of the same age and species into two separate tanks. The tanks were identical. He divided each tank in half by inserting a clear divider. The biologist placed the trout on one side of the divider and a large predatory fish – the northern pike – on the other side. He then recorded the amount of time it took the trout to move to the back of the tank away from the northern pike. The biologist found that the hatchery fish moved away much slower than the wild fish.
