Scientific Inquiry A Look at the processes that tell how Science is Done

Scientific Inquiry Different ways scientists study the natural world- an ongoing process of discovery. Posing questions Developing hypothesis Designing Experiments Collect/ interpret data Draw conclusions Communicate ideas/ results

A way of learning about the natural world by gathering information

The study of the properties of matter.

Using your senses to gather information.

Quantitative: #’s OR measurement Qualitative: Uses 5 senses: Sight Hearing Touch Smell Taste

Physical science is the study of matter, energy, and the changes they undergo.

Inferring An inference when observations are explained using reasoning and logic. “Logical”

Predicting Making a forecast of what will happen in the future based on past experience or evidence.

3 skills scientists use to learn more about the natural world are: – Observing – Inferring – Predicting

Hypothesis Possible answer to a scientific question or explanation for a set of observations This is an IF/Then Statement followed by a “because” Explanation

Variables Factors that can change in an experiment. Factors that can change in an experiment. Manipulated (independent) variable Manipulated (independent) variable Variable that is changed purposely Responding (dependent) variable Responding (dependent) variable Changes as a result of the changing manipulated variable

Controlled Experiment An Investigation in which ALL of the variables remain Unchanged except one. An Investigation in which ALL of the variables remain Unchanged except one. A control does NOT change

Data Facts, Figures, and other evidence gathered through observations. Data is recorded in charts, graphs, and data tables Facts, Figures, and other evidence gathered through observations. Data is recorded in charts, graphs, and data tables All of this data is recorded using the metric system or SI (International System). All of this data is recorded using the metric system or SI (International System).

Communication Sharing Ideas and conclusions with others through: Sharing Ideas and conclusions with others through: Notes Notes Reports Reports Speaking Speaking This is the main reason all the metric system (SI system) is used. People all over the world use and understand it This is the main reason all the metric system (SI system) is used. People all over the world use and understand it

Scientific Theory A well tested explanation for a wide range of observations or experimental results. There are many theories but this is the one backed by Science and recognized by the State of Arizona
