Rules for Keeping an Engineering Design On the front of the notebook, enter the project title, your name, and other informationneeded to return the notebook to you in case it is lost.Keep a table of contents at the front of the notebook.All entries must be done in ink.Design notebooks do not have to be neat, but they must be legible.a. Do not be obsessed with neatness at the expense of faithfully recordingeverything as it happens.b. Do not crowd the materials on the pages.Make your entries at the time you do the work.a. Include all results and learned information whether favorable or unfavorable.b. Include all information even if you do not fully understand it at the time of entry.If you make errors, just cross them out with an X or a single line.a. Do not mark through anything so that it cannot be read.Do not erase anything.Never tear a page out of the notebook.All data must be in their original form (calculations, charts, pictures, sketches on scrappaper, etc.), not after recalculation or transformation.Rough drawings should be done directly in the notebook. More careful drawings such asmachine drawings or computer-generated plots should be made and taped or glued in thebook.Information on loose sheets of paper should be entered into the notebook by:a. Taping the loose paper to the next available blank page in the notebookb. Taping each corner of the loose paperc. Use a tape that will accept ink permanentlyd. Place your signature on the loose paper, continue across the tape and end on thedesign notebook page. Sign across each corner of the taped pare. Date the signature.Information that can be retrieved easily (such as research articles from journals) should notbe entered into the notebook. Enter only the needed information and the location and thelocation of the information in case you must retrieve it again.Title each page of the notebook and enter the information on the Table of Contents.Sign and date the notebook page at the space provided at the bottom.Have your design entries Reviewed and have the witness sign and date at the spaceprovided.a. The witness needs to have the technical ability to understand the entry.b. The work can be reviewed periodically.Every page of the notebook must be numbered.This is a chronological record of your work.A good engineering design notebook is one that can be used to reconstruct your work even yearsafter you have completed the original project. Other engineers should be able to use the notebook toreconstruct your work. The notebook will be used to determine the rightful owner of patents andother proprietary ideas.2

Leaning Tower of GumdropsThe ChallengeOne common constraint that engineers must overcome is the strength and quality of the materials chosenfor construction. Your team is charged with designing and constructing a tower of using only gumdropsand ionGum ticsRulerHorizontalHeightAir ResistanceHair dryerBaseStabilityConstraints You have 30 minutes to construct your tower. You can only use 30 gum drops and 100 toothpicks provided in the build. Minimum height 6 inches. Max base is 6 inches in any direction You may use technology (phones, tablet, or computer) for your Learn For your project to be presented and judged you must have your drawing, plans, and your areas ofcompetition organized in your Design NotebookDeliverables1. Self-standing tower that is at least 6 inches high and no more that 6 inches wide.2. Tower must withstand level one through three of hurricane forces.3. It must be able to be transported to the judging standTimeframeThink – (3 min) Review common tower designs and construction materials.Talk – (5 min) Brainstorm tower designs and building solutions.Plan – (5 min) Draft design and calculate. Plan how it will be assembled as a teamLearn –(4min) Discover the mathematics, physics, and engineering principles guiding your build.Build – (8min) Draft tower design with edges and vertices clearly identified, then build tower.Look Back – (5 min) Test and refine tower to meet all of the design specifications.Scoring Rubric (for all categories information must be in the notebook and presentation)I. Build the most realistic buildinga. a designated entrance and egress (1-4 points)b. a pitched roof structure (3-9 points)c. at least two additional features found in buildings (3 points per feature)II. Build the most robust building (Rationale for each feature required)a. survive transportation to the judging stand (0-1)b. withstand low grade forces and manipulation by the judges (0-1)c. withstands category I wind forces (0,1) * seconds for up to 15 secondsd. withstands category II wind forces (0,2) * seconds for up to 15 secondse. withstands category III wind forces (0,3) * seconds for up to 15 secondsIII. Build the tallest building (Rationale for each feature required)a. Measured from first contact with surface to the tallest perpendicular point (2*height incentimeters)4

Roller CoasterThe ChallengeRoller Coasters are fun because they feel and seem dangerous but are really safe. One common constraintthat engineers must overcome is the strength and quality of the materials chosen for construction.

RoboticsEducational Robotics (ER) Based STEMLesson PlanThe ChallengeEducational robotics (ER) have been shown to positively effect students’ academic achievements andtheir attitudes and perceptions towards STEM subjects. However, all students do not have access to thepotential of ER due to high cost of proprietary ER such as LEGO and VEX. Open source ER can helpencourage access for all students to the promise of ER. You and your team will design an ER basedSTEM lesson plan and demonstrate its implementation using “OpenBrick”, an open source Arduino basedER kit.MaterialsOpenBrick ER kit/ mBlock 5 software/ OpenBrick extensionCardboard boxes, box cuttersHot glue gun, packing/duct tape, masking tapePencils, pens, markersWooden dowelsMeasuring tapeNotebookConstraints You must use only your assigned OpenBrick ER kit and accompanying software. Your lesson must address one or more STEM TEKS.Deliverables Provide a complete 5E lesson plan to your peers. Conduct a short ( 5 minute) demonstration of the lesson to your peers and justify the elements ofthe lesson plan. Upload the lesson to Aggie STEM’s website for sharing with a wider audience.Timeframe Think – Review currently available ER kits. Talk – Discuss the equity issue raised by high cost of proprietary ER kits and how OpenBrick canhelp. Plan – Design an ER based STEM lesson plan using OpenBrick ER kit Learn – Acquire general knowledge about ER and specific knowledge about OpenBrick ER kit. Build – Assemble the robot using the OpenBrick ER module and other parts that the students willuse during the lesson. Look Back - Test the robotic component of the lesson plan to ensure that students cansuccessfully use it during the lesson and prepare the presentation.7
