 Lab Report – Applying Scientific Method – Pillbug Preference

 

What is your hypothesis for this experiment?

What is your strategy?

What is your experimental setup for the top choice chamber?

What is your control setup for the bottom choice chamber?

 

Experiment steps:

  • Add cornstartch to the left side of upper choice chamber.
  • Use other spoon to add sand to right side of upper choice chamber
  • Add sand to both right and left sides of the lower choice chamber
  • Add 5 pillbugs to the right and left sides of the top choice chamber
  • Add 5 pillbugs to the right and left sides of the bottom choice chamber
  • Record pillbug counts in Lab Data every 2 minutes up to 12 minutes.

 

My Hypothesis:

Pillbugs will move toward the choice chamber containing cornstarch, because they are attracted to cornstarch

My Strategy:

I will add 5 pillbugs on the left and 5 pillbugs on the right and count the number of pillbugs on each side at regular intervals of time.

Experiment Setup:

I will put cornstarch on one side of the chamber and fine sand on the other side of the chamber.

Control Setup:

I will put sand on both sides.

My Conclusion:

The pillbugs tend to move toward the cornstarch, and the control group shows they don’t change behavior regarding sand.
