DAY 125
Hello students,
If you'll like to Zoom in for a Q & A, I'll be available today from 2-3 at the link below. If that time doesn't work, next week we should have structured office hours time for each of your courses. Just as you're trying to navigate this new way of life, we are too :).
If you'd like to view some Rube Goldberg machines from last year, here's a video: https://youtu.be/aUKDd2acj-k
I'm here at school clearing out the room, as the construction is still moving forward, and room 37/38 + the shops are still slated to be demolished over spring break. You'll be getting lots of updates this week, as the district and VHS are ramping up efforts to maintain regularish learning opportunities. As usual, feel free to Remind message or email if the zoom doesn't work for you.
Be well,
Mr. Alexander

Essential Question: How can energy be transferred?
GOALS: SWBAT...
1. build functional machines
2. work together successfully
3. describe how energy is transferred
WARM-UP 125
1. When is your test day?
2. When is your paper due?
3. Give an example of a Class 3 lever.

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
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 link: http://lmgtfy.com/?q=screw+rube+goldberg or an alternate link: https://www.google.com/search?q=screw+rube+goldberg
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. Exam Thursday. Begin studying.
Topics: the six types of machines, the three types of levers, and the ways energy can transfer.
2. Test Revisions are now late: 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.
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 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)
Unit Schedule (revised)
Mon: Background knowledge.
Tue: knife safety, (what kind of simple machine is a knife?)
