Science is a process for producing knowledge. The process depends both on making careful observations of phenomena and on a hypothesis for making sense out of those observations.
Scientists start with observations and then make a hypothesis (an educated guess), and then the fun begins. They must then prove their hypothesis with trials and tests that show why their data and results are correct. They must use controls, which are quantitative. Science needs both ideas (the hypothesis) and facts (the quantitative results) to move forward. Scientists can then examine their data and develop newer ideas. This process will lead to more observation and refinement of hypotheses. Science does not prove or conclude; science is always a work in progress.
Scientists pose, test, and revise hypotheses based on research outcomes.
Hypothesis
- a statement that uses a few observations
- an idea based on observations without experimental evidence
Example: A fossil forms when mud and dirt surround an object and then it dries and forms a rock.
This week we will be focusing on fossils. You will learn how to form a hypothesis and how to test it.
On a piece of paper, in your own words tell me what a hypothesis is. Give an example of what a hypothesis would look like about fossils.
