Nature of Science by Robert Fiero https://padlet.com/robert_fiero/7042o9ew76ez Science Methodology Unit en-us 2016-07-18 23:00:41 UTC 2017-07-28 22:58:03 UTC hello@padlet.com robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116580822 Basic Principals of Modern Science: It is a way of knowing (sense making) the truths of reality (Natural Universe) and to solve problems (i.e. engineering and technology) but is does not apply well to issues such as ethics, values, and the supernatural (metaphysical) as well. Science can be experimental or observational.]]> 2016-07-18 23:03:13 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116580822 Characteristics of Successful Scientists robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116581312 Curiosity & Observant
Fairness & Openness to New Ideas
Diligence/Perseverence
Honesty/Integrity-attending to precision.
Creativity
Intelligent and educated
Skepticism-questioning what is known.
Adventurous-at least intellectually.]]> 2016-07-18 23:13:22 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116581312 Practices of Scientists robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116581489 Observation & Measurement -- collecting data (information).
Experimenting- controlling and isolating variables
Designing solutions & Constructing explanations.
Engineering applications-test designs and solutions
Evaluating and communicating information.
Use computers, maths, logical thinking, and data programs, etc.
Modeling and Simulating natural phenomena.
Often use high tech equipment-sensitive to variables tested.
Internet-sharing research, communicating ideas, etc.
Graphing of data and statistical analysis to see if it is significantly useful.
Track data over time, surveying information, and comparing data & results.
STE-A-M: Science, Technology, Engineering, Art, & Mathematics.
Peer Review-analyzing each others research conclusions etc.
Replication Studies-fact checking each others procedures and results.]]> 2016-07-18 23:16:13 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116581489 What are some kinds of questions that scientists might explore? robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116582892 How can I find out about what I can’t see, what happened before, what could have happened?
How can I find out how it works?
How can I find out what causes what?
How can I know it or test it to see if it’s true?
What evidence can I find to what I infer (explain) is true?
What patterns can I find? How can I show the pattern I found to others?
How can I measure it?
How can I use data to support my theory?
Forming arguments on issues from evidence.]]> 2016-07-18 23:43:56 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116582892 robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116598800 Click on "View Original."]]> 2016-07-19 03:28:32 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116598800 DATA: robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116598838 Two Types of Data/Observation: Quantitative (numbers from measurements) &. Qualitative (descriptive) Information
With this data scientists can discover patterns and principals in Nature.
Sample size is important in gathering useful data. Obviously the greater the sample size the more significant the information.
Also doing many repetitions helps in gathering enough data to have significant results.
Best data is both accurate (close to reality) and precise (consistently similar).
Often the average (mean) is most significant but sometimes outliers (extremes) are important.]]> 2016-07-19 03:29:23 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/116598838 Traditional Scientific Method (it is very dynamic-the process can be changed at anytime) robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/116719051 1.State a Problem or Question

2.Hypothesize/Predict

3.Investigating: Design an Experiment (Variables)-one to change and others to control and keep constant. Carefully written and performed procedures.

4.Take Data/Observations-Data tables or measurements-to gather evidence to disprove or support ideas.

5.Analyze Data-graphing & statistical analysis.

6.Draw Conclusions and Publish/communicate research.

They need to be written so they can be tested. Science is building on previous knowledge with critical analysis by those who study the topic (peer review). ]]> 2016-08-04 22:55:35 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/117568890 Types of Variables robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/117572986 The variables are any factor in your research that could affect what you discover as a result or measure/observe.
Independent/Manipulated Variable: The one factor that is managed/applied to be different intentional. It was is being tested.
Dependent/Respondent Variable: is what happens as a result that is measured or observed and collected as data.
Controlled Variables or Constants: All of the other factors other than the two above that are kept the same throughout the research to make it a fair test or comparison.]]> 2016-08-05 00:06:42 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/117572986 robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/118613727 Claim-Evidence-Reasoning]]> 2016-08-17 16:22:09 UTC https://padlet.com/robert_fiero/7042o9ew76ez/wish/118613727 NGSS Connections to the Nature of Science robert_fiero https://padlet.com/robert_fiero/7042o9ew76ez/wish/179664346 Scientific Investigations Use a Variety of Methods
