Now that you have completed this module, you have learned that science is different from other ways of knowing in that it is based on empirical evidence obtained through systematic observation and experimentation. It is not based on opinion or beliefs. Scientists work together collaboratively; yet they challenge each other through the process of scientific argumentation to reach consensus. This process ensures that theories provide the best explanations of the physical world and its processes.

Scientists must remain skeptical when considering claims and must question all information to ensure that their conclusions are based on valid and reliable evidence. Scientists accept that science does not establish absolute certainty and that scientific claims and conclusions are always open to revision as new information or evidence is discovered.

Now that you have completed this module, you may return to the home menu to begin the next module, Weather and Climate.
