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).

2 ) Plan and carry out investigations that explain transference of energy from
place to place by sound, light, heat, and electric currents.
a. Provide evidence that heat can be produced in many ways (e.g., rubbing
hands together, burning leaves) and can move from one object to another by conduction.
b. Demonstrate that different objects can absorb, reflect, and/or conduct
c. Demonstrate that electric circuits require a complete loop through which
an electric current can pass.

4 ) Design, construct, and test a device that changes energy from one form to
another (e.g., electric circuits converting electrical energy into motion,
light, or sound energy; a passive solar heater converting light energy into heat
