Scientific Method
This step requires you to make an educated guess about the outcome of the experiment.
Hypothesis
Travels perpendicular to the medium
Give an example of qualitative data
see answers
Signals stop and go
digital signals
As the wavelength increases/decreases the.....
pitch changes
This step requires you collect data and organize it into a graph or table
Analyze and Interpret Data
The only wave/ light that humans can see
Visible Light
Numerical data
Quantitative data
Give an example of digital signals
computer, phone, CD/ DVD, ipod
What is the light that has the HIGHEST frequency?
Gamma Rays
What is the first step of the Scientific method?
Identify the problem/ create a question
This wave has amplitude, crest, trough, and wavelength
Transverse wave
Give an example of quantitative data
signals that are continuous ( do not stop)
Analog
as the frequency increases/ decreases the ......
loudness or softness changes
This step requires you to tell the reader what you learned from the experiment
Share data & draw conclusions
Travels parallel to the medium
Longitudinal Waves
Observation based data
Qualitative data
Draw what a digital signal looks like
look at drawings
What is this statement? "There is a puddle so it must have rained last night"
Inference
What is the purpose of the Scientific Method?
To collect scientific data and answer scientific questions.
This wave has compressions and rarefactions
Longitudinal wave
There is a blue sky with clouds. What type of data is this?
Qualitative
Give an example of analog signals
cassette tapes, cameras, tvs, analog clock
What is this statement?: " Three out of five children completed their pacer test"
Quantitative/ Observation
