Knowing, Inquiry & Technology

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
