Class 8: Friday, 9/20/18

Warm Up:  Can you help me design a solution to the problem depicted on the right?  The picture was taken after everone left the room yesterday.

 

Today:

  1. Another way to solve video format problems with an Iphone -- in camera settings, choose "most compatible."
  2. Test and experiment with your trebuchet version 2.0, document with photos/videos.  It would be good to include some data (throw distances, for example)

** I realized that I didn't create links to all of the subpages.  You will have to do that at some point.

Upcoming Classes:

  • Today  -- test version 2.0
  • Monday (9/24) -- build and tune final version 3.0.
  • Next Wednesday and Friday -- complete inventor's notebook entries (due Friday night).
  • Next Friday -- contest for prizes (≥ fruit snacks)
  • September 30th -- Actual VT Pumpkin Chuckin Competition, in case you want to make a big version of your trebuchet, and compete.

Homework: Update your inventor's notebook through the planning stage of Version 2.0.

Class 7: Tuesday, 9/18/18

Warm Up:

The Where Does It Belong? Quiz

1. Bolt cutters    2. Tape    3.  Safety glasses    4. Hot glue sticks    5. Rulers

6. Pliers    7.  Scissors    8.  New wood    9. Wood scraps    10.  Hot glue scraper

11. Heat gun    12. Fishing line    13.  Hot glue gun    14.  Hand drill    15.  Nice set of drill bits

16.  Tape measure    17.  Paper clips    18.  Metal file    19.  Sandpaper 

20.  Broom and dust pan    21.   Shop vac

Today:

  1. Who has shared a notebook and who has begun filling in the important parts?  Check powerschool.  I will soon be adding a weight to the notebook check grade.  That weight is currently zero.
  2. How to solve lightning cable video transfer problems from iphones to computers:  Go to settings -- photos -- transfer to mac or pc -- select "keep originals."  Iphones are now using HEIC and HEVC files, instead of .jpeg and .mov.  Trouble happens when phones try to convert videos during transfer.  Windows 10 can show and play the original HEIC (high efficiency image format) and HEVC (high efficiency video coding) files.  Windows 7 can't play them, but even if you can't see the video, you can upload it to YouTube and your Google Drive (I think).
  3. Check out the "coach my video" app.
  4. Finish version 2.0, document with photos/videos. 

** I realized that I didn't create links to all of the subpages.  You will have to do that at some point.

Upcoming Classes:

  • Today and Thursday -- test version 2.0
  • Monday (9/24) -- build and tune final version 3.0.

Homework: Update your inventor's notebook through the planning stage of Version 2.0.

Class 6: Friday, 9/14/18

Warm Up:  How do you change the bit in the drill press, and how do you reposition the bit?  What's the chuck? What's the chuck key?  What's a keyless chuck and what's the special trick for working a keyless chuck?  How and why might you want to reverse the drill rotation direction?

Today:

  1. Check out the "coach my video" app.
  2. Design an entirely new version of your trebuchet, version 2.0.  Reuse parts whenever possible, but feel free to discard ruined materials.  Do not throw away the rebar.  You can remove hot glue with pliers or the heat gun.  Put burnable pieces of wood in the scrap wood box.  A little bit of hot glue is okay.  Keep in mind that you will also build a 3.0.

** I realized that I didn't create links to all of the subpages.  You will have to do that at some point.

Homework: ** I plan to check these before next class -- probably on Monday.

  • Share your Google Site with Mr. Stapleton
  • Make sure that you have something in the Research, Brainstorming, and Planning Your Deisgn sub-pages in your inventor's notebook.
Class 5: Wednesday, 9/12/18

Warm Up: 

1.  What can we learn from this slow-motion video?

2.  How can you insert a video like this into your Inventor's Notebook?

Today:

  1. Announce Women Can Do conference
  2. Document your prototype version 1.0 in the "planning your design" main page. (or at least prepare to do so, before you destroy your evidence.)
    • In the  "completed prototype" subpage, insert one or more photo(s) of your trebuchet.
    •  For the "testing, reflections, and modifications" sub page...
      • create a slow motion video and embed it
        • Upload it to your google drive, change your permission to public (or anyone with a link).
        • Copy the link
        • Click the "insert" tab in your Google Site.  Then select "embed," to paste your link onto your web page.
      • Use text or a screencast to describe your observations and inferences relating to the slow motion video.  If you create a screencast, just embed the screencast and include text explaining that your observations are shared in the screencast. [Here's a link to some tutorials on using a chrome plug-in called "screencastify."  If you're using a desktop, you will need a microphone.  Most laptops should have internal microphones built in.]
    • Publish your Google Site and send  jstapleton@ewsd.org.
  3. Experiment with your version 1.0 trebuchet.  Don't be afraid to break it in the process.  Some variables you might want to modify are: sling length, finger angle, counterweight mass, arm thickness, and attachment to floor, but don't limit yourself to those.  Try whatever you want, and abuse your prototype as much as is necessary.
    • Describe what you learned from the experiments, if anything.
    • Insert more videos if it helps you explain your findings.
  4. Probably next class --- When you're done experimenting with version 1.0, begin building an entirely new trebuchet, version 2.0.  Reuse parts whenever possible, but feel free to discard ruined materials.  Put burnable pieces of wood in the scrap wood box.  A little bit of hot glue is okay.  Keep in mind that you will also build a 3.0.

** I realized that I didn't create links to all of the subpages.  You will have to do that at some point.

Homework:

  • Share your Google Site with Mr. Stapleton
  • Make sure that you have something in the Research, Brainstorming, and Planning Your Deisgn sub-pages in your inventor's notebook.
Class 4: Monday, 9/10/18

Warm Up:

1)  How does a trebuchet get its energy?

2)  How can you tell if your trebuchet is making efficent use of its available energy?

3)  What's the best way to learn as much as you can about your trebuchet's performance?

Today:

  • Get your projectile.
  • How to tie loops.
  • Try to finish your first prototype and shoot a projectile before the end of class today

Homework:

  • Share your Google Site with Mr. Stapleton
  • Make sure that you have finished the Research, Brainstorming, and Design Planning sub-pages in your inventor's notebook.
Class 3: Thursday, 9/6/18

Warm Up:

1.  Log on to a computer and open this Google Site Template

 

Today:

  • Create a Google Site using this template.  Insert evidence of your research, brainstorming, and design planning.
  • Upcoming plans:
    • Continued from last class --  Document your research, brainstorming, and initial design drawing.  You will be inserting these into a Google Site next class.
      • Research:  Collect and save some documentation of research (e.g. pictures of existing designs, helpful text, etc.)
      • Brainstorming:  Create and save a collection of thoughts about your design.  These could be pictures, notes, or both.  You can create the list o
      • Plan the Design:  Photograph or scan your design drawing.  Save it for insertion into a Google Site next class.
        • Create a drawing of a trebuchet prototype that you can build quickly.  The goal here is to get something working quickly so that you can learn more about the problems associated with your design.  Try to simplify your design as much as possible, with the understanding that you will create more refined versions.
        • Modify your drawing as necessary in order to simplify.
    • Begin working on a prototype that you can complete and be ready to shoot in one full block.

Homework:

  • Get your course expectations signed and then return them.
