1 Attention Getter

Begin the lesson with the video of a time-lapse MakerBot Replicator 3D printer building the NYC skyline.

Have students write down notes on the following questions:

  1. How does the 3D printer make an object?
  2. What would be important when creating a design for a 3D printer?
  3. How could a 3D printer be used in the real-world?
Student Instructions

As you watch the video, think about the following questions:

  1. How does the 3D printer make an object?
  2. What would be important when creating a design for a 3D printer?
  3. How could a 3D printer be used in the real-world?

2 Reflection on Video

Free, Free to try, Paid

Share link to Padlet with students.  Ask students to respond in Padlet with notes that they jotted down as they  watched the video.

Discuss the student ideas after they have had time to reflect and add their comments. 

Student Instructions
  1. Open up the link that was shared in Google Classroom.
  2. Add your name to your post in Padlet and write a reflective comment based on the notes that you took while viewing the video.

3 Characterization - Guided Instruction

  1. Print of share the list of character traits.
  2. Ask students to circle or highlight any traits that describe themselves.
  3. Select one of the traits that you would be able to draw an image that represents this trait.
  4. Turn your papers over and draw an object that would represent this trait.
  5. If students are having difficulty making the connection between traits and objects offer examples. A cat or a dog may represent kindness or caring.  A stop sign may represent stubbornness.
Student Instructions
  1. Read over the list of character traits and circle or highlight any that describe you.
  2. Select a trait that you would be able to draw an object that represents that trait.
  3. Turn your paper over and draw the image on the other side.

4 Tinkercad - Guided Practice

  1. Add students to Tinkercad class using https://projectignite.autodesk.com if students are under age 13. Students will have a code to use to join the class.
  2. Students complete Tinkercad tutorials while circulating throughout the classroom, assisting students.



Student Instructions
  1. Use code to join class at https://projectignite.autodesk.com
  2. Complete tutorials.
  3. Ask the teacher or another student for assistance if you have questions.

5 Create a 3D Model - Independent Work

  1. After students have completed the tutorials, have them create the image they drew that represents a character trait.
  2. Remind students to think in shapes as they design their object.  Discuss any problems they might have in creating their 3D object.
  3. Have students save the file  and attach it to an email for printing.
  4. Print final files for display.

6 Final Reflection

  1. Create a text question at https://goformative.com/.
  2. Ask students to reflect on the process of connecting a personal character trait to an object.
  3. Have students submit paragraph when they are finished.
  4. Display final 3D objects with the character trait.
  5. Finish with a gallery walk of 3D objects, having students write on post-its, two "I like" statements and one "I wonder" statements.
