DAY 122
Essential Question: How can energy be transferred?
GOALS: SWBAT...
1. show complete design, including all requirements listed below
WARM-UP
1. Have you read the entire project guidelines document?
2. Have you completed all your checklist assignments from Day 119-121?
3. What is the task of your machine?
4. Whats the most interesting energy transfer your machine with utilize?
CLASSWORK
1. 122A: Design
You should come up with ideas for the task of your machine, and the energy transfers your machine will use. If you're struggling, it helps to start with the last step, and work backwards from there.
Your design should be drawn, either using a sketch program on your computer, or via hand-drawing.
Designs should include:
list of materials
dimensions
methods of attachment for each object
energy transfers between stages
labels for each material
each of the 6 simple machines
not sure how to incorporate something like a screw into your machine? Here's a link with suggestions: https://www.youtube.com/watch?v=nrtO446Pjok
Prior to getting building materials, you'll need to get your design checked by me. You can do this by sending an image via Remind or email.
2. 122B: Work Time
LEARNING AT HOME
1. Complete any portions of Day 119-122 that are unfinished.

1. Which forms of energy must be used by your machine?
2. How many of the 6 simple machines must you use?
3. Does using a screw to attach a ramp to your board count as one of the six screw machines?
CLASSWORK
1. 120A: Design
Your group should come up with ideas for the task of your machine, and the energy transfers your machine will use.
Your design should be drawn, either using a sketch program on your computer, or via hand-drawing.
Designs should include:
list of materials

Prior to getting building materials, you'll need to get your design checked by me.
My expectation is that most groups will finish their design, and begin building, today.
2. 121A: Work Time
Before you get materials, you must be done with Day 117 (all three assignments), and your design must be approved by me.
Materials are organized on the demo desk. Whatever you take, make sure you put back in the same place
Materials under the demo desk are reserved for other periods and for other days of building.
Before you use something, make sure you've measured twice. Once you cut, it's over... ;-)
LEARNING AT HOME
1. Complete any portions of Day 117-122 which are unfinished. Those steps are your checklist to begin building.
2. Test Revisions: You can revise up to eight (8) questions, due Tuesday. You must state what the correct answer is, and explain in a sentence why your answer was incorrect, and/or why the correct answer is correct.
Period 1, I graded question #1 incorrectly for most folks. so if you got that one wrong, show it to me on Monday so I can check it for correct grading.

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, as of Saturday (03/23/19). 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.
soft 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)
tubes (from toilet paper or paper towel)
gear sets and or motors (like these: LINK)
binder clips
CD's (used is fine)
screws (drywall is best - drywall screws have threads that go allllll the way to the head of the screw
small nails
masking tape (brown or blue)
