Essential Question: How can energy be transferred?
GOALS: SWBAT...
1. build functional machines
2. describe how energy is transferred
WARM-UP 127
1. Were there any parts of your machine that you built, but later discarded? What motivated that choice?

1. Rube Goldberg Paper
Paper examples:
I've included a few graded examples of papers. Use them as examples and/or templates. Remind message or email with any questions. LINK: https://docs.google.com/document/d/1eWlQgicowoW-MBX8Mi91BBVT_xPQSCfuSFfAqazGNww/edit?usp=sharing
- Mr. A
From your project guidelines: https://docs.google.com/document/d/1NbvMBgjdU3HvjqoQVbV1dkhuEKZ3p5VnwZiVpAGwsKo/edit
Project Paper:
You will write a project paper that explains each step and each energy exchange. For example, this is an explanation of one energy exchange:
“The dominos are started on one side and each falls into the next. The Potential Energy of each domino drops as it falls and its Kinetic Energy rises. The final domino hits a marble so it does work on the marble to increase its Kinetic Energy. I chose this energy transfer because it showed both PEg and KE, and because it was reliable and repeatable. It worked every time.”
Your paper should include why you constructed each energy transfer the way you did and describe the materials you chose. For example, let’s say you needed to raise a marble so it could gain more energy. You might use a pulley system, and state, “I used a pulley with string and two cups to increase the height of a marble. Increasing the height meant the marble would have more potential energy, and therefore have energy to continue moving components in the machine”
2. Machine building
3. Thermodynamics Exam & Simple Machines Quiz
- make sure you've completed both. Assignments are on schoology

WARM-UP 127
1. What was the most difficult component of your machine to build?
2. Why?
3. were there any parts of your machine that you built, but later discarded? What motivated that choice?

CLASSWORK
1. 127A: Project Process Reflection (6min)
Think-Pair-Share (2min-2min-2min)
1. Imagine that as a senior, you have to build one of these RG machines for an Engineering class. Think big picture - what from your process of working with others, designing, building, testing, and modifying would you change?
2. What would stay the same in your process?
3. We spent approximately two weeks on this unit. Think about what you learned. Why was this, or wasn't this, a good use of your time?
2. 121A: Work Time/Testing Time
- Didn't finish? Come back at nutrition. You WANT to test YESTERDAY. I will be here at nutrition. Also, if you need to test Tuesday, you can do so at nutrition or lunch. You'll lose 2 points per day that it's late
3. Paper Writing
Rubric and Instructions are here:

4. Project Evaluation
Self Evaluation: LINK
Partner Evaluation: LINK
LEARNING AT HOME
1. 127B: Answer Post-learning knowledge inventory (from day 117)
2. Complete Self and Peer Evaluations (now late)
2. Write Paper (group assignment) - due Fri 11:59pm
3. Test Revisions are now super late, but you can still get 20% if you turn them in Tuesday. Better than nothing..
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.
For all, #22 was graded incorrectly. The exam is now out of 38 instead of 39

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 Friday (03/29/19). 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:
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)
wide popsicle sticks
balloons
