Week 1 is about team building and identity. Students will work together on various challenges and study of structures. This week students will begin to learn about Vollis Simpson and form their own style and identity.
Check Point 1- Students should have completed their team logo and have evidence of using the engineering and design process in their activities from the week.
Week 2 is about beginning the Engineering and Design process for the development of the students’ kinetic sculpture. Students will be using the E&D process worksheet as a framework for developing their project proposals. This week will be spent Identifying the problem, constraints, and imagining (brainstorming) different options to their problems. Students will be working from the wikispace as they begin to study Vollis Simpson’s work, simple machines, and computer aided design. As students complete each section on the E&D process worksheet they must have it approved by the teacher before moving to the next section.
Check Point 2 – Students should have a completed 3D Model in the CAD software and should be beginning to workout detailed pieces of the model. Students should be able to begin construction at this point. Materials selected by the students should be approved by the teacher before permitting them to bring them to school. Encourage using recycled materials. – End of Week 2
**Note Students in my class have access to a 3D Printer and CNC machine, while this is nice it is not necessary for this lesson.**
Week 3 is devoted to the create phase of the project. Students will have to have reached check point 1 and have been approved to proceed to the create phase.
Week 4 is for completion of the sculpture and finalizing the project proposal for the team.
Final presentation of project proposal scored according to the rubric
Introduction to Engineering and Design Powerpoint and using the Decision matrix to test options (20 min)
Activity: Card tower (25 min)
100 pack of index cards per team of 4
One copy of Decision Matrix per team
Class challenge is to use the pack of index cards to build the tallest card tower possible.
The only intended constraints are time (25 min) and the number of cards(100). Do not prevent students from folding or tearing cards but do not tell students to fold or tear either. Let them struggle until they succeed. Encourage student to use their decision matrix to document the pros and cons of what they have tried. Take measurements as students announce they have finished and write them on the board with the ranking of heights. Update the numbers as the student continue to try and out do the other teams.
To reinforce the Engineering and Design process and to continue team building students will be completing the Marshmallow Challenge
Activity: Marshmallow Challenge (25 min)
Count down timer projected on the board set to 18 minutes
Each team of four will need the following
20 Sticks of Spaghetti
1 meter of 1/2” masking tape
1 meter of string
1 large marshmallow
Teams are given 18 minutes to build the tallest free standing spaghetti tower they can that will support the marshmallow at the top.
Teacher notes: Encourage the use of the decision matrix to create a quick plan. They should sketch some ideas for the tower framing. The original website and TED talk can be found at: http://www.marshmallowchallenge.com/Welcome.html
Debrief this activity by discussing the results of the structures and the team dynamics.
Continuing to create team unity and understanding the Engineering and Design process at work students will be combining the previous two activities. Today’s marshmallow is a 2 to 3 pound textbook. Students will reengineer their card tower experience to be tall and hold a load. The goal is to construct the tallest card tower that is capable of supporting a small textbook.
Activity: Tall and Strong Card Tower (40 min)
Each team will need the following
100 Index Cards
Small text book (Each team should have the same book)
Teacher Notes: Students will want to reassemble the tower they did on day 1 right away. Encourage them to rethink their towers for the new constraint and to test the load bearing capacity frequently rather than waiting to the end. As with the other activities write the current place holders on the board to encourage working toward the tallest structure.
Introduce students to the wikispace. Today they will begin to study the Vollis Simpson Wind machine as well as the life of Vollis Simpson to gain an understanding of kinetic sculpture. Student will explore the contents of the wikispace to include the challenge, CAD/CAM videos, Simple Machine videos, and other related content. Teams will decide on the roles each member will fulfill as Project Manager, Accountant, CAD Programmer, and Promoter. All students are ultimately responsible for the construction and delivery of a working prototype.
Use VTS to study Vollis Simpson
Teams will begin to develop a logo for their team and research successful branding. Students should brainstorm different designs to try and capture the identity of the group. Teams will want to consider how their team identity will be reflected in the final structure
Students will explore simple machines and try to identify simple machines present in the Vollis Simpson Wind Machine and how they are used. Students will complete simple machines investigation by calculating the IMA and conducting experiments to find the AMA at stations around the room.
Activity: Simple Machines Investigation
Incline plane station
Wheel and axle station
Students will be using the Engineering and Design worksheet to begin the development of their project proposal. They will use the decision matrix to brainstorm options for the beginnings of their structure by identifying the constraints and researching the location of the display site. Students should be encouraged to begin 3D modeling of their structure immediately. This will give them some idea of spatial locations of parts, proportions and provide a visual of what they want to work toward.
Day 7-10 Students should be going back and forth between Imagine and Plan in the engineering and design process for each piece they are integrating into their sculpture. Between their decision matrix documents and the Autodesk modeling students should be able to create a plan for approval to move to fabrication of parts.
