This project addresses at least two of the content standards:
3.4.5 Science/Physical Science
Scientific progress is made by asking meaningful questions
and conducting careful investigations. As a basis for
understanding this concept, and to address the content the
other three strands, students should develop their own
questions and perform investigations. Students will:
repeat observations to improve accuracy, and know
that the results of similar scientific investigations
seldom turn out exactly the same because of
differences in the things being investigated, methods
being used, or uncertainty in the observation.
differentiate evidence from opinion, and know that
scientists do not rely on claims or conclusions unless
they are backed by observations that can be
use numerical data in describing and comparing
objects, events and measurements.
predict the outcome of a simple investigation, and
compare the result to the prediction.
collect data in an investigation and analyze them to
develop a logical conclusion.
3.8.1 Science/Physical Science
The velocity of an object is the rate of change of its position.
position is defined relative to some choice of standard
reference point and a set of reference directions.
average speed is the total distance traveled divided by the
total time elapsed. The speed of an object along the path
traveled can vary.
how to solve problems involving distance, time, and average speed.
to describe the velocity of an object one must specify both
direction and speed.
changes in velocity can be changes in speed, direction, or
how to interpret graphs of position versus time and speed
versus time for motion in a single direction.
