- 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.
Course Digital Resources:
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.
Today your unit and presentation need to be done, shared to me at ChristopherTyler@oflschool.org. or dropped off at the Wilson Center in the mail slot. Additionally, Remember you will need to pass the unit 9 test with at least a 70%. I will print out the test results.

Task #1 – Electricity Student Work / Careers Research Project Turn In
Right now you need to do the following:
- Finish Unit 9 – Unit 9 – Mr. Tyler Version
- Share your Google Slideshow to ChristopherTyler@oflschools.org if you have not already.
For this project you need to complete the following:
#1 – Google Slideshow with the following slides:
- Title Slide (Name of Career and your name)
- How this job benefits society
- Education required for position
- Vacation time it allows
- Duties the job entails
- Hours of work
- Work Environment
Task #2 – Unit 9 Test.
Head to Socrative.com and enter room “A89559b4” to begin the test.
Clear all materials from your desk before starting.
Task #3 – Introduction to Unit 10 – Magnetism Activity
In this introduction activity I want you to list materials you think might be magnetic and then find out if they are or are not. (Example: Steel vs Aluminum)
Task #4 – What is Magnetism?
YouTube -> Magnets and Magnetism
Task #5 – Magnetic Fields
Comprehension Check -> Physical Science Unit 10 – Magnetic Field Check
Task #6 – Grand Challenge (Unit 10)
Based on what you know, you now need to tackle this engineering challenge…
Congratulations, you have just been hired by the recycling company to streamline their sorting process. And, by streamline a sorting process, I mean you have a room full of metal that you need to sort into valuable steel, and considerably less valuable aluminum. You will be paid based on how much steel you can remove from this room per day. Remember, truckloads of mixed scrap metal will arrive daily, so you must be able to separate it efficiently. What are some ways to separate the steel from the aluminum? Think about time and cost efficiency. For example, hiring manual labor will be slow and costly.
Google Slideshow shared to ChristopherTyler@oflschools.org
- Introduction Slide
- Description of the problem
- Explanation of magnetism
- Proposal of how to sort this mess effectively.
- Pros/Cons to design
- How are you going to address the cons?
- How will your proposal consistently be a solution (Describe automatic sorting process, space and machinery needed etc)
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.
