Today we’ll continue with the Tinkercad Fractals project, and iterate on your first draft designs. If your designs are well-defined fractals then you’ll print them in class; if not then you’ll redo them and print after class.

Discuss the following with your group members:

- Is your object a fractal? Why?
- What “level” of your fractal is illustrated in your print? What exactly is the “rule” for your fractal? If you can’t answer these questions then you might need to redo your design.
- Would you be able to measure the length, area, and/or volume of this level of your fractal? What information would you need to know in order to do that? If none of these questions seem answerable for your model, then you might want to redo your design.
- Do you think your fractal will print successfully? Why or why not? How big will it have to be to print successfully?
- If you’ve made it through all the bullet points above, then you can start a print of your fractal now, if it will finish before the end of class. Otherwise come in later with swipe-card access to complete your print.
- Does your blog post satisfy all the requirements so far? Make a careful double-check, including: Featured Image, embedded images at “full size”, section headers, group names, title is the name of your fractal and not “Tinkercad Fractal”, post is tagged with “Tinkercad Fractal” category, etc. Read carefully through the Tinkercad Fractal Example post to check that you’ve discussed everything necessary and satisfied any other requirements.

So we can start thinking about “dimension”, we’ll watch the first part of this 3Blue1Brown video in class (up to 7:45), and pause occasionally to do some of the math on the board.

For next class you’ll fix up anything in your blog post that needs fixing, print and document a copy of your Tinkercad Fractal first draft, and watch a video about the perimeter and area of the Koch snowflake; see the Assignments page for details.
