Lesson Plans
Strand 3.3: FORCE AFFECTS MOTION
Forces act on objects and have both a strength and a direction. An object at rest typically has multiple forces acting on it, but they are balanced, resulting in a zero net force on the object. Forces that are unbalanced can cause changes in an object's speed or direction of motion. The patterns of an object's motion in various situations can be observed, measured, and used to predict future motion. Forces are exerted when objects come in contact with each other; however, some forces can act on objects that are not in contact. The gravitational force of Earth, acting on an object near Earth's surface, pulls that object toward the planet's center. Electric and magnetic forces between a pair of objects can act at a distance. The strength of these non-contact forces depends on the properties of the objects and the distance between the objects.
Standard 3.3.4
Ask questions to
plan and carry out an investigation to determine
cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other. Emphasize how static electricity and magnets can cause objects to move without touching. Examples could include the force an electrically charged balloon has on hair, how magnet orientation affects the direction of a force, or how distance between objects affects the strength of a force. Electrical charges and magnetic fields will be taught in Grades 6 through 8. (PS2.B)

3RD GRADE MOTION AND STABILITY: FORCES AND INTERACTIONS
A lesson that uses magnets to address standards 3.3.1, 3.3.4 and 3.3.5 (Weebly).
-
A Hair Raising Experience
Balloons are used to help students explore static electricity.
-
Paper Clip Walk
A magnet is used to make a paper clip "walk" on a paper plate. Students investigate how many paper plates through which the magnetic field will still pass.

Third Grade Writing Lesson #2 / Science Prompt
Students will invent a gadget using one or more simple machines. They will then write a detailed description of that gadget.
