number of vibrations past a point in a given amount of time
distance from crest to crest
long wavelength-low frequency- low pitch
short wavelength- high frequency-high pitch
a distanse which results in the moverment of molecules
-must have a medium
-travels longitudinal or compressional
distance from baseline to crest
unit used to measure the loudness of a sound
reflection of a sound wave
when two or more sound waves interact
-constructive sound waves reinforce on another
-destructive the sounds waves cancel one another out resulting in beats
fundamental tone plus overtones
sound vibration that have a regular pattern
sound waves that have an irregular pattern
animals and man to detect underwater objects
sounds below the range of human hearing
sounds above the range of human hearing
apparent change in the flequency of a sound as the distance between the source of the sound and the receiver of the sound changes
has a single correct answer
can be answered in a number of ways
Using Questioning to Intiate Inquiry
What do you see happening?
What is puzzling about you observed?
What have you seen that is like this?
Using Questioning to guide discussion of observation
what are some of the changes you noticed?
in what order did the events happen?
why do you think there were differences in each group's measurement?
were the observation of all groups the same? why or why not?
Using question to guide discussion of explanation
did you notice any patterns in your observation
what do you already know that might help you explain what a happened
what principles or laws can you think of that might explain what happened
using questions to guide discussion of aplication
what might happen if
how can we use this principle to explain
responding to student ideas and answers
incorpate an attitude of intital acceptance of student responses and ideas
extend student response
build on an idea suggested by one or more students
clarify student ideas by restarting the idea in simpler terms
compare and contrst ideas presented by two or more students
probe student responses
ask questions that build on student ideas
ask students to clarify their response by giving more information, explaining a term used, or restatating the response in other words
consideration in questioning
increase your wait time and your wait-time two
gradually fade you questioning support to encourage students to formulate their own question
help students to develop cognigively and construct their own concepts and understanding
