Physical Science B SGI Lesson #18 (3-25-2019)

Topic:

Introduction to Electricity

 

Unit:

9

 

Objectives:

  • Relate the flow of electrons to current.
  • Correlate the flow of water with the flow of electricity in a system.
  • Explain that static electricity is the buildup of a charge (either net positive or net negative) over a surface.
  • Compare and contrast two forms of electricity—current and static.
  • Name a few engineering careers that involve electricity.

Vocabulary/Definitions:

atom: The basic unit of all elements of matter.

conductor: A substance that allows the easy movement of electricity.

current: Something that flows, such as a stream of water, air or electrons, in a definite direction.

electricity: The presence or movement of electric charges. Electric charge occurs when a net difference in charged particles (such as proton or electrons) exists.

electron: A particle in an atom that has a negative charge, and acts as the primary carrier of electricity.

insulator: A substance that does not allow the easy movement of electricity.

proton: A particle located in the nucleus of an atom that has a positive electrical charge.

static electricity: A stationary electric charge buildup on an insulating material.

 

Warm Up: 

Your last good ping-pong ball fell down into a narrow metal pipe embedded in concrete one foot deep.
How can you get it out undamaged, if all the tools you have are your tennis paddle, your shoe-laces, and your plastic water bottle, which does not fit into the pipe?

 

Agenda:

Task #1  – Electricity Unit Student Work 

I will be giving each of you a copy of this PDF file for you to do on your own or with a partner.

PDF -> Unit 9 – Electricity Unit Homework

 

Task #2 – Electrical Careers Research Project

First read through the handout and look over the jobs you can choose from. Then, once you have chosen, you will come up to the board and write your name and the career you chose to research. There can be no repeats. First come, First served style.

Sign Up Sheet -> Electrical Careers

I will be giving each of you a copy of this PDF file for you to do on your own.

PDF -> PDF – Electrical Careers Research Project

Project Specifics:

For this project you needs to complete the following:

#1 – 5 Paragraph Research Paper explaining the electrical career you chose.

#2 – 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

Due Date: 4-1-2019 (Make sure both paper and slideshow are printed out and ready to hand in.

 

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.
