4th Annual Egg Drop Challenge!

We will conduct the 4th Annual Engineering Egg Drop Challenge this week!

Your goal is to design and implement a solution for our client that allows us to drop an egg from our class balcony onto the concrete below without it breaking.



The PLTW 12 Step Iterative Design Process (click to enlarge):




Our agenda for Egg Drop Week (this week) supports an iterative design process:

Monday is "Prep Day"
Team up with a partner
Define the challenge, criteria and constraints.
Brainstorm solutions.
Identify materials to bring in for "Build Day" (block day)

You must bring in the materials you want to use for Block Day!


Block Day is "Build Day"
Use the materials you've brought in to realize the vision of your design.
Crash test dummy eggs will be provided.
You may test your design off the balcony


Thursday is "Test Day"
Click here to see correct drop technique.


Friday is "Iteration Day"
Redesign as necessary.
Reimplement your design.
Capture your experience in your portfolio.


Score
An Achievement System will be used to score your effort on this activity.
The number one priority in this effort is to not make a permanent mess (no Jello, materials that will stain, etc. If you have any question about materials, please see Mr. Olson).
Our next priority is to have a great time solving this challenge! :)
Please note that all materials used in your solution must be "delivered" from the launch location (you may not place additional material on the target from the ground for instance).

TED Challenge 2014! Part II

Now that you've picked, viewed and taken notes on a TED Video (TED Challenge Pt I), it's time to move to the second part of the activity.


You will work with your team. Each student in the group has a unique talk they felt was exciting and relevant to the class.

The objective of your group is to:
1) Negotiate within your team to decide which video you'll use to represent the group.
2) Once your group has agreed on a video, prepare a breif presentation for the class.
3) Be prepared to present your talk when asked to do so.

Your presentation should:
A) Play the TED video your team chose. Be sure to introduce your video. Provide a little bit of context for what the class is about to experience :)
B) Each team member will prepare a conversation starting question for the class (open-ended "how" and/or "why", not Yes/No).
C) Explain how a student could get involved in the field in question in the future.

You will be able to use the class projector to support your presentation.

Points are awarded for:
(1 pt) The student who's talk is chosen to represent the group earns a point.
(1 pt) All the memebers of the group who's presentation is chosen as the best of the class earn a point.
(3 pts) Each student in the group earns a point for each of the above three presentation criteria (A, B, C) that are met in their talk.

Food for Thought:
-Will you argue for your video as the best to earn extra credit for yourself?
-Or will you support your team by picking a different video that will best help the group's chances?
-Or are you so sure of your own video that you feel it should be chosen for your group and that it will win the class competition as well?

TED Challenge 2014! Part I

Go to TED.com and spend some time investigating the site.

Once you've had a chance to familiarize yourself with the webpage, answer the following questions:

1) What is the TED organization about?

2) What is the purpose of their website and how does the functionality of their site support that?

3) As Engineers and Problem Solvers, which topic areas (the choices from the "Show talks related to:" section on the sidebar) are of most interest to us? Justify your answer.

4) Based on your previous answer, what are 3 talks (videos) on the site that appear like they would be of most interest to you as an Engineer/Problem Solver? Justify your choices.

5) Each student will watch a unique video (clear your choice with me... first come, first served!). Watch the video. Embed the video in your blog post and create a bulletized outline of the key issues presented in the talk.

6) How could you get involved in the field/technology/issue you chose to hear about? What experience/skills/training/education would you need to learn to get involved with this field?


Part II of the TED activity will have you negotiate within a group to select the "best" video to represent the group. The student with the chosen video will recieve extra credit. The group will then prepare a short presentation that summarizes the talk and will present to the class. The class will choose the best presentation and that group will recieve extra credit.

Machine Control (Robotics!) Capstone Project 2013-14: Marble Sorter Challenge!

Welcome to our Principles of Engineering Machine Control (Robotics!) Capstone Project for the 2013-14 school year. This is an exciting opportunity to work with your partners to develop a unique solution to an open-ended problem.

You will earn "Achievements" based on both the process you apply and the product you build. The team that earns the most "Achievements" wins!

This project is worth 7 points per week we spend on it and is capped at a maximum of 25 points. The top team will earn 100%. The second place team will earn a 92%. The third place team will earn an 89% and the fourth team will earn 85%.


Process Achievements:

Organize it!: Title your post and organize it by section in a logical manner.

Brainstorm!: Provide at least four of your team’s brainstorming ideas for the design solution. This should include brainstorming sketches. Each sketch should include labels and descriptions for communication.

CAD!:
Use our Inventor CAD software to model a prototype or your final design. Post screenshots of your model.

Enter the Matrix: Evaluate your solution ideas (4 minimum) using a decision matrix. Determine the best solution to the problem. Explain your rating system and share insight on why you rated your solutions as you did.

Design Solution: Create a detailed pictorial sketch or use 3D modeling software to document the best solution, based upon your team’s decision matrix. Your sketch or 3D model should include a rationale for the design selected as the final design solution. Each sketch should include labels and descriptions for communication.

"I've Made a Few Special Modifications...": Document modifications made to your design during implementation. Explain the reason for the modifications and describe how the new design solution will solve the problem. "Story" is the split between expectation and outcome. Tell us a story regarding what your plan was and how it actually came out! Use photos and sketches to call out three changes. (Nerd points if you know where the quote for this Achievement title comes from)

Final Implementation: This section will showcase your final hardware and software solution. Include photos of your hardware and program. Call out atleast three key features of your design that were significant to its performance. Report how your solution performed in the challenge.

Final Implementation - Video!: Embed a video that showcases your solution in action!

Reflection: Adress the four feedback types that we use in our courses (+, -, ?, !). Solicit feedback from someone outside of your team as well.
Some questions to consider in this section: How well did you accomplish your objectives? What would your team do differently with your design solution and why? Do the results fulfill the problem statement? Provide a brief explanation of what you learned, the challenges of working in a design team, and the purpose of the design problem.

Reference: Post a hotlink to material you referenced on the internet. Explain why this information is significant to your project.
