Zoom lesson today from 11:00-11:30

ESSENTIAL QUESTION: How can I prove that light is a wave?

Goals: 

SWBAT 

1. Define Refraction

2. Use concept of refraction to explain why light bends

CLASSWORK

1. 163A,B,C,D: Refraction 

Slideshow: LINK

WARM-UP

Use circuit diagram symbols

1. make a circuit diagram showing a battery, wires, and two resistors in parallel

2. make a circuit diagram showing a battery, wires, and two light bulbs in series

Advanced Circuits & Components

• What's a switch? What's a resistor? Capacitor? Transistor? 

• You likely know some of these terms, but not all. 

• We'll spend  today's class using, and learning about, the major components of circuit. 

• Things you'll do:

  • create real circuits that make lights flash, make sounds, etc.

  • diagram circuits using symbols

  • research circuit components, and describe their function

  • discuss what you've learned

• Things you'll use:

  • instruction manual:

    • describes function of circuit. explains how it works

  • circuit diagram book.

    • tells you where to put the parts, and which parts to use.

      • note: parts numbered "1" are 1st level, "2" is 2nd level, "3" is 3rd level

• Assignment: Learn about circuits components, and how they work, by completing 4+ "Switch On!" mini-labs

  • You can start with any of the circuits above #4. 

• Assessment: You'll create two documents, both of which will be at least a page long:

  • 1. 163A: Lab Summary Doc (3 columns) : Mini-Lab Title; Circuit Diagram (AKA schematic); Concepts Illustrated in Lab

  • 2. 163B: Circuit Components (4 columns): Component Name; Symbol; Function (what it does); How Does It Work?

• Groups: 3-5 students per kit, depending on class size

Learning at Home (HW)

- complete Guided Reading: Magnetism

- work on your final review

- Textbook Return Thursday

- Senior Final Periods 5 & 6 on Thursday or Friday (or both. your choice, let me know)
