PHYSICS - Impress me with your SKILLZ!
YES! You have made it! Through turbulent and crazy times, you have made it. Good job!!!
"But Mrs J, where is Physics?"
FEAR NOT my little Gremlin!!! I have planned a fun thing for you since the beginning.
The topic for grade 9 science is circuits! Let's first review the basics, and then we can move forward with something fun!

The topic for grade 9 science is circuits! Let's first review the basics, and then we can move forward with something fun!
Mini Lesson 1: What Makes a Circuit Work?
Let's see how electricity lights things by looking at a quick demo, using a battery, a little light and some wire.
Can you make the light work?
Then, let's look at a very odd piano! :D Can you figure out how it is working?
Student question:
“On room lights, where is the break in the circuit?”

Mini Lesson 2: Conductors Vs. Insulators
Let's test some materials and see if we can guess how they will behave.
Testing tray: foil, paper, pencil graphite, coin, eraser, cardboard, Play-Doh, fruit, dry sponge, wet sponge, plastic spoon, metal spoon.
Make a quick table:
Material
Prediction
Test: Did it conduct?
Strong/weak/weird?
Why do we think that happened?
Conductors are materials that allow electrons to flow, while insulators do not!

Mini-Lesson 3: Switches are Tiny Decisions
A switch is a controlled gap. You decide when the circuit closes. Your task is to build 3 types of switches.
Press switch: Light turns on when you press a button.
Tilt switch: Uses gravity. Light will turn off or on, depending on the position of the object.
Door switch: opening or closing the door causes the switch to turn on.

Mini-Lesson 4: Resistance
Resistance is how much a material or part of a circuit makes it harder for electric charge to flow. It is caused by moving electrons colliding with atoms inside a conductor, which converts some electrical energy into heat. Resistance is measured in ohms (Ω).
To find the resistance, you can use the following formula:
To find the resistance, you can use the following formula:
Current (I) is measured in amps, Voltage (V) is measured in volts, and Resistance is measured in Ohms (Ω)
Skill question!
1) Imagine you have a circuit with a 12 V battery and a resistor of 6 ohms. What is the current flowing through it?
2)Calculate the current of the following circuit.

2)Calculate the current of the following circuit.
They can test graphite lines: short thick line vs. long thin line. Which works better?
Mini-Lesson 5: Input, Output, and Human-Computer InteractionMakey Makey pretends to be a keyboard. Scratch reacts to the “key.” The physical world becomes the controller. This is exactly the bridge between circuits and code. Scratch’s Makey Makey page describes it as letting students control programs with conductive objects like food, tape, graphite, metal, Play-Doh, and the human body.
And now, for the project!!!
THE SHALAMALAM
BABAP BOP!
Or whatever you want to call it!!!
You can divide yourselves into groups of 2 or 3.
"mRS J, CaN wE --"
NO MORE than 3! No asking! I mean it! :(
For this project, you will create a contraption that works a certain way, to do a certain thing; you can use cardboard, wood, old things you may have, and even the 3D printers to print bits for your project.
You have until the end of class to impress me with your coding and creativity and design and ability of making something useful (or very useless but hilarious or at least mildly amusing).
To make your Shalamalam, you will be using a contraption called Makey Makey. Let's watch the video below to understand:

The Makey Makey interface allows conductive things in the world to be used as controllers.
"What are conductive things, Mrs J??"
Oh child. That's for YOU to figure out!

DELIVERABLES
The Contraption
A machine that works when plugged into the computer, controlled by code.
The Code
Scratch is recommended. You may research online and adapt/modify code already existing as long as you understand how they did it!
