More resources to come. Information will be posted here, and copied to Schoology.
Ask questions via the Remind App or via email (josh.alexander@lausd.net).

Essential Question: How can energy be transferred?
GOALS: SWBAT...
1. list the requirements for the Rube Goldberg project
2. Assess their current knowledge of simple machines
3. Define "machine", and the six types of simple machines
4. Compare and Contrast the three classes of levers
5. Describe three energy transfers
WARM-UP
Think about Kinetic Energy, Gravitational Potential Energy, and Elastic Potential Energy.
1. In a string of Dominoes, how does one falling domino transfer energy to another?
2. How would a rolling ball transfer energy to a stationary block if the ball slammed into the block?
CLASSWORK
Notes:
In order to 1) build your Rube Goldberg Machine, and 2) test it, you'll need to go through the knowledge building process, and the design process. Knowledge building is what you did on Friday, and will continue today. Depending on where you are progress-wise, you may start your design today, or Tuesday.
There are some samples of materials on the demo table in the front of the class. Feel free to come up and take a look at what I have. Also, you can bring materials from home, either just for your group, or to share (or both).
1. 117A-117C: Complete Friday's Work (if necessary)

2. Group Choice.
Groups of 2-4 work best.
Only one person in your group needs to do this --> Make a copy of the RubeGoldbergProject document, put your group members names on it, and share it with me. Link to document: https://docs.google.com/document/d/1NbvMBgjdU3HvjqoQVbV1dkhuEKZ3p5VnwZiVpAGwsKo/edit?usp=sharing
3. 118A: Types of Energy Exchange
list the three types of energy (Kinetic, etc).
Consider a system or two objects. Draw three examples of how energy can be exchanged, and explain how energy transfers from one object to the other.
4. 118B: Project Idea
Choose, or come up with a project idea, and a backup
A list of project ideas are in link4 of the project guidelines and rubric: https://docs.google.com/document/d/1NbvMBgjdU3HvjqoQVbV1dkhuEKZ3p5VnwZiVpAGwsKo/edit?usp=sharing
LEARNING AT HOME
1. Quiz on 6 simple machines this Wednesday
2. Complete any portions of Day 117 or 118 that are unfinished. Those steps are your checklist to begin building
EXTRA CREDIT OPPORTUNITY:
Want some? Our Rube Goldberg project is materials heavy, so, if you'd like to donate some common materials to class, I will reward your support with points.
Things which are larger, or more expensive (boxes, glue sticks, springs) will get more points per item than something small and cheap (one used Hot Wheels car, for example)
Here's what we need, preferably on Monday (03/18/19) or Tuesday (03/19/19). Keep in mind that this is a live list - I'll take things off the list if we have enough of that material. Also, if you think of something, and are wondering if it might be useful, just ask in class or via the Remind App:
Moving size (approx 18x12x12" or larger) boxes. Used in good condition is great.
popsicle sticks (new, not used - thanks)
springs
hot glue sticks (like these: https://www.amazon.com/Diameter-Compatible-Industrial-Adhesion-Quickly/dp/B07GTJ88KT/ref=sr_1_7?keywords=hot+glue+sticks&qid=1552582849&s=gateway&sr=8-7)
used matchbox size cars/trucks that roll well (they can be beat up cosmetically)
toilet paper or paper towel tubes
gear sets and or motors (like these: LINK)
string/yarn/string
marbles
binder clips
CD's (used is fine)
screws
small nails
masking tape (brown or blue)
