MS-PS2-5: Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

MS-PS3-2: Develop a model to describe that when the arrangement of objects interacting at a distance changes, different amounts of potential energy are stored in the system.

● I can identify how positive and negative charges interact.

● I can identify how north and south poles interact.

● I can draw field lines to represent the strength of the interaction between charges and between magnets.

● I can use the parts of a controlled experiment to evaluate an investigation.

● I can explain how the distance between two objects affects the strength of the force.

I can describe how electricity and magnetism affect each other.

• How do positive and negative charges interact?

• How do north and south poles interact?

• How can field lines be used to represent the strength of the interaction between charges and between magnets.

• How does the distance between two objects affect the strength of the force.

• How to electricity and magnetism affect each other.
