Standard(s):
[SC2015] (3) 1 : 1 ) Plan and carry out an experiment to determine the effects of balanced and
unbalanced forces on the motion of an object using one variable at a time,
including number, size, direction, speed, position, friction, or air resistance
(e.g., balanced forces pushing from both sides on an object, such as a box,
producing no motion; unbalanced force on one side of an object, such as a ball,
producing motion), and communicate these findings graphically.
[SC2015] (3) 3 : 3 ) Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).
[SC2015] (4) 1 : 1 ) Use evidence to explain the relationship of the speed of an object to the
energy of that object.
[SC2015] (4) 3 : 3 ) Investigate to determine changes in energy resulting from increases or
decreases in speed that occur when objects collide.
[SC2015] (5) 6 : 6 ) Construct an explanation from evidence to illustrate that the gravitational
force exerted by Earth on objects is directed downward towards the center of
Earth.
[SC2015] (5) 7 : 7 ) Design and conduct a test to modify the speed of a falling object due to
gravity (e.g., constructing a parachute to keep an attached object from
breaking).*
