Students set up the stream table apparatus seen here. They began their experimentation with trials to determine the velocity of a stream at various inclines. Students measured the length of the stream from the head to the mouth of
the stream. They began with one block under the head of the stream table. A steady flow of water was directed
through the opening at the head of the stream. Once the water was flowing, a cork with a string attached was placed
at the headed of the stream. Students timed the movement of the cork from the head to the mouth. They ran three
trials and found the average speed of the cork. They repeated the procedure for a 2-block raise and a 3-block raise.
The results of the students trials can be seen in the data table. Describe the relationship between stream velocity and
incline.
-
A)
There is an inverse relationship between stream velocity and incline of the
stream table.
The greater the incline of the stream table, the greater the velocity of the
stream.
B)
The velocity of the water is not related to the incline of the stream table.
D)
There is a direct proportion between incline and velocity.
