Down with Earth's Little Wormy
Michelle Guevara, Katie Daniels, Aimee McCulley, & Jacy Vest
I wonder if we evenly distributed the 8 earthworms into three petri dishes, placing eight worms in the middle dish, then have two other dishes connected, one with the natural dirt of the earthworms, and the other with red dirt, if they would evenly distribute between the dirt and natural dirt
2. Fifteen Earthworms
3. Red Dirt and Caliche Dirt
4. A timer
Manipulated Variable Procedure:
If the drops of water increase it would make our sample of the red dirt, too moist and mud-like for the earthworms to be observed in.
Three petri dishes connected by tape each with a different substance inside, one that is empty, one with red dirt, and one with the dirt the worms are used to. We will keep these in a controlled environment and use them towards the hypothesis.
(0-4)^2/4+(3-4)^2/4 = 4.25
We fail to reject our null hypothesis.
