What are four real life examples of the results of scientific investigations

When you're growing a plants and their not growing.

1) Put them in shade all day, they have good soil and I water them.

2) "I think it might be better if they got less sunlight"

3) I put one in the shade and one in the sun, keeping everything the same.

4) The one in the sun grew better.

5) Now I know to keep my plants in the sun.

Crime scene

1) hypothesis "my keys are in the jacket pocket"

2) Test 1 - Checks in pocket- They're not there

3) Hypothesis " there on the counter"

4) Test 2 - Checks on counter - Not there

5) Hypothesis " I left them in the front door's lock"

6) Test 3 - Checks door- They're there.

Proving the hypothesis, measuring something and causality.
These or only two examples but I hope you get the memo.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
