Observations and communication are important among biologist that study amphibians because observations are shared among other biologists and more questions are answered through the observations.
Scientists make hypotheses (an educated guess) in scientific investigations that can be tested for additional information and observations. Predictions are expected outcomes of a test assuming the hypothesis is correct, scientists use and test their predictions to gather data, observations, measurements,etc. Lastly, scientists use experiments as a procedure to test a hypotheses and confirm it as true or false.
An independent variable is a factor that is varied and can be altered during an experiment. The dependent variable is the measured variable
