### Objectives:

• Explain how magnets can be used to separate different metals.
• Identify metals that respond to magnets.
• Explain how engineers use properties of magnets in everyday applications.

### Vocabulary/Definitions:

steel: A metal formed of a solid mixture of iron and carbon.

compass: A small magnet suspended so that it can freely point to Earth’s magnetic north pole.

lodestone: A naturally magnetized piece of the mineral magnetite.

### Next Generation Science Standards:

HS-PS2-5. Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.

HS-PS3-1 Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

HS-PS3-5. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
