1 Hook / Attention Getter

Activity: Exploring

Teacher will introduce the problem that the students have to solve:

  • The school has some very heavy doors, especially in the Pre-K wing of the school, that students are unable to hold open
  • If the door closes, students may be unable to pass through those doors
  • Students will need to work in teams to engineer a door stopper that is able to hold these doors open at a 90 degree angle

Bring students to one of the doors in your school, and observe some of the objects that may be currently keeping the door open.  Discuss how these objects may be keeping the door open.  Most of the objects will be wedges, which are simple machines, which they have already learned. See if students can identify that this is a simple machine.

Student Instructions

Students will talk with their classmates about what objects they see keeping the door open, and if they think it is possible to recreate this object in Tinkercad.

2 Direct Instruction

Once back in class, ask the students to identify some objects that might be abe to hold the door open.  Feel free to model how the door will react to certain objects being used to hold it open.  For instance, a rubber door wedge will work fine, but if you put a pencil in the door frame, the pencil will break rather easily.

Review the basics mechanics of Tinkercad.  They must know thow to resize objects, hole out objects, and group objects.  This is not a lesson you should use to introduce Tinkercad.  This is a lesson that can be used for students who are fairly comfortable with Tinkercad.

Student Instructions

Have students brainstorm different objects which might be able to hold the door open, explaining how the object can hold the door open.

Have students log into their Tinkercad accounts, and practice making basic objects.

3 Guided Practice

Activity: Drawing

Have the students break up into groups, and share their ideas for objects which can keep the door open.  Once they are done discussing, they should begin blueprinting their design on a piece of paper.

Student Instructions

Students will discuss their ideas with their teams, and when they are done, they will blueprint their design on a piece of paper.

4 Independent Practice

Once the students have finished blueprinting their door stoppers. they will go through the Engineering Design Process in Tinkercad, and begin designing their door stoppers in Tinkercad. 

This is an ongoing activity, so choose different student's projects to print out and test as a door stopper in a door.  Based on the outcome of the tests, the students will discuss with their teams and redesign to address any issues with their designs.

Since doors can be very dangerous, it is VERY important that YOU test out the door stopper, and have the students observe.  Never let students put their fingers anywhere near the door, especially the hinge.

Student Instructions

Students will engineer their blueprints in Tinkercad.  They will redesign as needed, based on their observations of other door stoppers, or on the performance of their door stopper.

5 Wrap-Up

Print out the students' (or teams') door stoppers, and have them test out their door stoppers in a door. 

Again, since doors can be very dangerous, it is VERY important that YOU test out the door stopper, and have the students observe.  Never let students put their fingers anywhere near the door, especially the hinge.

They should have already gone through the design process numerous times by this point, so these door stoppers should be near or at completion.

Student Instructions

Students will receive their printed door stoppers, and with the teacher's help, will test their final product in a door in the school.
