UNIT 9 WORK:

Right now you need to do the following:

1. Finish Unit 9 – Unit 9 – Mr. Tyler Version

Project Resources:

Project Specifics:

For this project you need to complete the following:

#1 – Google Slideshow with the following slides:

• Title Slide (Name of Career and your name)
• Hazards
• Pay
• How this job benefits society
• Education required for position
• Vacation time it allows
• Duties the job entails
• Hours of work
• Work Environment

UNIT 10 WORK:

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.

• 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.
