|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
