| theory | idea to explain something that is based on observations and support which comes from scientific investigations |
| experiment | organized procedure to study something under controlled conditions experiment; organized procedure to study something under controlled conditions |
| observations | using your senses to obtain(get)information |
| hypothesis | a testable idea that leads to a scientific investigation |
| data | information gathered by observation or experimentation that can be used in calculating or reasoning (data is organized using charts and graphs) |
| independent variable (test) | test-the variable that is deliberately manipulated in an investigation (what you change or are testing) |
| dependent variable (outcome) | outcome-changed as a result of the manipulation of the independent variable (the result or outcome) |
| model | representation of an object or a process that allows scientist to study something in greater details |
| inference | using your observations to make a guess about an object or an outcome |
| Steps of the Scientific Method to solve a scientific problem | Ask a Question, Form a Hypothesis (possible answers),Test the hypothesis using an Experiment,Collect and analyze Data using charts and graphs & Conclusion-was your hypothesis supported or not supported |
| qualitative Observation | when studying something: describe only facts that you can see, touch, taste, smell and hear (ABC's) |
| quantitative Observation | when studying something describe only facts that you can measure (1,2,3-Numbers) |
| prediction | a statement or claim that a particular event will occur in the future. |
| control group | the group in an experiment that does not change |
| repetition | when you do something over and over again |
| replication | when you repeat an investigation that someone else has done ad get the same results |
| trials | in science, it is how many times you repeated the same experiment, the average number of times is three |
| valid | in science, after completing an investigation, you must determine if you can count your results or if you need to retest. Valid means that it counts. |
| pseudoscience | "false" science but often resembles science but does not have evidence |
| environmental science | study of our planet’s natural systems and how humans and the environment affect one another which includes living and nonliving |
| natural resources | materials and energy sources found in nature that humans need to survive |
| renewable resources | naturally replenished over short periods |
| nonrenewable resources | naturally formed more slowly than we use them |
| environmentalism | social movement dedicated to protecting the natural world |
| ecological footprint | the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources |
| peer review | scientists review papers submitted for publication, recommend changes, and reject or accept the paper for publication |
| ethics | study of behavior (good and bad, right and wrong), moral principles, and values |
| culture | ensemble of knowledge, beliefs, values, and learned ways of life shared by a group of people |
| worldview | perception of the world and a person’s place in it |
