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.
