Method Steps Observation – You have to look around to find a pattern/problem Hypothesis – An educated guess at what may be causing something or how to solve a problem. Experiments – Test the hypothesis and produce data. Analysis – Gather all the data and determine what has been found. Conclusion – Does your hypothesis seem like the likely cause? Communication – Let everyone else know what you have found.
3
Like all science, biology is a process of inquiry.
Scientists make careful and systematic observations. Scientists record observations as data. Scientists form a hypothesis as a possible answer to a question. Scientists test their hypotheses and analyze their data.
4
Biologists use experiments to test hypotheses.
Observational studies allow scientists to describe a phenomenon.
5
Experimental studies allow scientists to determine what causes a phenomenon.
6
Independent variables are manipulated.
Experimental studies allow scientists to determine what causes a phenomenon. Dependent variables are observed and measured. Independent variables are manipulated. Constants are conditions that are kept the same.
7
Models Scientific Models, or modeling, are the 3rd type of study/experiment. Models are created by plugging data into computer simulations that will allow scientists to potentially predict what happens out in nature. Used to Study: - Dangerous events - Large scale phenomena - Rare phenomena
8
A theory explains a wide range of observations.
Theories explain a wide range of observations and experimental results. A theory is supported by a wide range of scientific evidence. Theories can change based on new evidence.
