Knowing, Inquiry & Technology
| Term | Definition |
|---|---|
| Analyzing & Presenting Data | Makes inferences (assumptions or presumptions) Recognizes patterns in the data Uses tables, graphs and charts to help analyze the data as well as present the data |
| Benefit | – an advantage; promotes or enhances well-being Benefits society beyond its original purpose |
| Drawback | – a disadvantage or inconvenience Leads to the need for greater scientific knowledge i.e., the computer, cell phones |
| Data Collecting Techniques | --Observation; Measurement; Experiments Laboratory tools used to assist in this collection may include: Microscopes; a balance; a computer; calipers AND others |
| Dependent Variable | Variable being measured in an experiment CHANGES in response to "the controller" (independent variable); Y-Axis |
| Ethics | Differences between good and bad or right and wrong Morality of doing something Reduces bias and prejudice Code of Ethics scientists must follow -- *Perform research honestly *Report results accurately *Cannot influence experimental results |
| Hypothesis | An educated guess MUST be testable i.e., If a plant receives fertilizer, then it will grow to be bigger than a plant that does not receive fertilizer. [Having fertilizer is the independent variable.] |
| Impact | Effect or impression of something upon another i.e., the computer & the cell phone |
| Independent Variable | the “CONTROLLER” CAN BE changed to find out how the change affects the other variable(s) |
| Laboratory Tools | Tools and equipment used by scientists working in a laboratory. Include tools such as bunsen burners, and microscopes as well as Laboratory glassware such as the beaker. |
| Questions to consider with TECHNOLOGY | What are the benefits? What are the risks? Are rights of individual (human/animal) respected? Does it do more good than harm? |
| Scientific Inquiry | Process used to find answers; Guides research; Used to ask valid questions; Gather & analyze information |
| Scientific Method | Steps SCIENTIST use to answer questions and solve problems— (1) Ask a Question; (2) Form Hypothesis; (3). Design/Conduct Experiment; (4) Collect/Analyze Data; (5) Mke Tentative Conclusion (5) Test Conclusion or Refine Steps ex Why car does not start? |
| Technology | Uses scientific knowledge for practical purposes i.e., tools, machines, other devices |
| Test Groups | Good experiments will have two groups (Experimental & Control) EXPERIMENTAL–contains independent variable [the controller]; Receives changes; Performs experimental procedures CONTROL–remains constant; no change Compares results of experimental group |
| Theory | Attempts to explain observations and information AFTER many observations and hypothesis testing by scientists may be accepted |
| Variable | Quantity that changes or stays constant in an experiment TWO types Independent Variable- Dependent Variable |
| Independent Variable | a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. |
| Dependent Variable | It is something that depends on other factors. When looking for a relationship between two things--trying to find out what makes the dependent variable change the way it does |
