Unsafe lab practices Actions in the laboratory that can lead to accidents, injuries, or contamination, such as not
wearing protective gear or improper handling of chemicals.
Testable hypotheses Statements that can be tested through experimentation and observation, predicting the
relationship between variables.
Qualitative vs quantitative Qualitative data describes characteristics or qualities, while quantitative data involves
numerical measurements and statistics.
