Question

True/False In the pillbug experiment, it is important that measurements be taken twice: once at the beginning of the experiment and once at the end of the experiment.

Answer 1

The statement is true. In a pillbug or any scientific experiment, measurements are taken twice. Initially to provide a baseline, and finally to gauge changes.

Step-by-step explanation:

The statement is true. In any scientific experiment like the pillbug one, it's common to take measurements at least two times. The initial measurement helps establish the baseline or starting point. The final measurement then helps determine the change that occurred during the course of the experiment. This way, you can compare results and deduce the effect of the independent variable on the dependent one.
