Classes 9 and 10: Monday, 9/24 and Wednesday, 9/26

Mr. Stapleton is attending a funeral in Georgia.  You know where things are and where they should be returned.  Please do a good job cleaning up!  Also, share the rebar weights.  There should be plenty of weight to go around if no one has weights hidden away that are not being used.

Specific Plans for Monday:  Wrap up your building and experimentation.  Get your trebuchet ready for competition on Friday.  You may want to weigh your projectile and trim it until its weight is close to (but not less than) 3.6 grams.

Wednesday Plan:  The main focus should be on completing your inventor's notebook pages.  If you did not get to a version 3.0, then just stop at 2.0.  Make sure that the pages are linked, and that the links work.  If you want to change the format, that is okay, but keep the same pages with the same titles as the template.

Participation in Friday's contest is mandatory.  You need to have a working trebuchet, even if it's no good.  You will get three throws.  Your score will be determined by the distance your projectile travels in the air.  Only your best throw counts.  We will be throwing in a location where your projectile will not hit the ceiling.

Homework: Work on your Inventor's notebook.  It is due on Friday at midnight.

Class 8: Thursday, 9/20/18

Warm Up:  There was a problem (photo on right).  I designed solution version 1.0, which was a "where does it belong" quiz, below.  The results of version 1.0 are on the right (photo taken after class on Tuesday).  Please help me brainstorm ideas for a more effective solution to the problem.

 

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.

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.
Class 2: Tuesday, 9/4/18

Warm Up:

1.  Triangles are often incorporated into structures, because they add stability.  Why are triangles stable?

2.  If you wanted to easily wiggle the frame trebuchet on the right, where would you push it, and in what direction?

 

Today:

  • Turn-in course expectations.
  • Trip to Mr. Stapleton's van to get boxes and supplies.
  • Assemble and label your box
  • Trebuchet Problem parameters and constraints
