Grade Level Expectations:
appropriate tools and techniques to make observations and gather data to
determine how forces, including friction, act on an object to change its
position over time in relation to a fixed point of reference.
the average speed of a moving object, and distinguish between
instantaneous speed and average speed of an object.
and interpret distance-time graphs for objects moving at constant and nonconstant speeds.
the motion of an object given the magnitude and direction of forces acting
on it (net force).
and demonstrate how unbalanced forces cause acceleration (change in speed
and/or direction of an objectís motion).
in writing the relationship between an objectís mass and its inertia when
at rest and in motion.
mathematically how the mass of an object and the force acting on it affect
and conduct an experiment to determine how gravity and friction (air
resistance) affect a falling object.
how the circular motion of an object is caused by a center-seeking force
(centripetal force) resulting in the objectís constant acceleration.
FROM THE MOUTHS
OF SCIENCE STUDENTS:
are a fight between the Earth and moon. All water tends towards the moon,
because there is no water in the moon, and nature abhors a vacuum. I forget
where the sun joins in this fight."

come from test papers and essays submitted to science and health teachers by
elementary, junior high, high school, and college students and compiled at the
NEA Life Sciences Symposium, Kansas City, Kansas. As the originator noted,
"It is truly astonishing what weird science our young scholars can create
under the pressures of time and grades."
