Lesson: Electric Forces Science • 3rd Grade

Students will be able to

• explain that matter is made of small particles, and these particles can have electric charges,
• explain that electric charges can be positive or negative, and that an object can have an overall positive, negative, or neutral charge,
• know that like charges repel and opposite charges attract,
• know that electric forces can act at a distance,
• know that increasing the distance between electric charges weakens the electric force between them,
• know that increasing the amount of electric charge increases the size of the electric force,
• explain that materials can be classified as conductors or insulators depending on how easily charges move through them,
• understand the term static discharge.
