As the sun gets higher in the sky, your shadow gets longer.

False.

Explanation:

When the sun gets higher into the sky, your shadow becomes shorter. If you dont believe me, take a flashlight and pencil/pen. Hold the pencil/pen up right on a flat surface, then take the flashlight and making a half circle (Like making an umbrella like top over it). Then you will see that your shadow becomes shorter the closer to the center it is.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
