Statistical Test 

I used averages to compare all of the trials, and make an accurate generalization to compare to my hypotheses. 

Control: 5+3+4= 12/3= 4cm 

Sunlight: 13+9+17= 39/3= 13cm

Shade: 6+5+11= 22/3= 7.33cm

Analysis 

My data supported my experimental hypothesis and refuted my null hypothesis. The data shows that the earthworms crawled the farthest distance when originally placed in the sunlight with the shaded end present. The average distance crawled was greater in the shade then the control but the earthworms did stay in the shade never leaving the edges of shade. The earthworms in the control stage were unmotivated to do anything. since the earthworms in the shade were active but not making a mad dash for the other end, it is reasonable the conclude that they prefer the shady, darker environments to sunny, bright ones. 

Conclusion 

My experiment proved that earthworms prefer shady environments to sunny ones. This finding make sense when one looks at where the earthworms live, in the soil. It also offers insights into the Darwinian theory of natural selection.The earthworms main predator is the bird and birds spend most of their time above ground in the sunlight. The fact that the earthworms evolved in such a way as to prefer the deep dark soil, would keep them away from the birds and safer. This is exactly Darwin's theory, that organisms that adapt to survive, live long enough to pass those life saving skills on to their offspring. That is a reason the earthworms prefer the dark.
