1 1.1 Variables

The independent variables are the acids used, the dependant variables the height of the bubbles formed and the control variables the test tubes used.

2 1.2 Safety and Environment

The safety and environmental precautions for this lab are quite strict. Wear safety goggles and a lab coat to avoid getting any acid on your person, and dispose of the acids in a sink with plenty of water. Collect the used liver samples and dispose of accordingly.
