Physical Science B SGI Lesson #23 (4-10-2019)








  • 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.

PDF -> How Magnets Work Book Scan (1965)



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.



Task #1  – (Magnetic Inventions) -> News Article 

Project -> Physical Science Unit 10 – Invention Project Packet

Task #1 should already be done and ready to continue developing today just like the Grand Challenge.


Task #2  –

By today you should have completed brainstorming your invention, that is the first half of your packet of instruction. You now need to get ready for presenting your invention. Like you can see in the back half of your instructions you will need to finalize how you want to present your inventions. You can either record it and send me the video file or you will have to act out the commercial in class. You have 1 minute to sell the room on your magnetic invention. If you have any questions e-mail me. Be ready to present this coming Monday April 15, 2019. Like the directions say be ready for questions about your invention and be ready to explain how it works and how the magnetism in your invention can help mankind.


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.
