GroupsAmeer & Sana
Manar, Rehan, & Fatima Maria & Dena Jouwana, Umaimah, Noor & Maya PositionsEach of the people in your group must be assigned one of these positions. For groups with fewer than four people, some people will need to take on more than one responsibility. The positions are:
Account Manager: This person is responsible for either keeping receipts for all items purchased OR looking up the price for items used on homedepot.com. If you have used items you have at home, that's wonderful, but I'd still like to know what it would cost. Engineer: This person is the person who is mainly responsible for designing the roller coaster. Project Manager: This person is responsible for keeping people on task and ensuring that ALL other people are doing what they are supposed to do. If someone is absent on an important work day, the project manager takes over. Quality Control: This person is responsible for ensuring that every marble run is the same as the one before. You will be responsible for ensuring that the roller coaster is built with quality. Important dates1/21: Get into groups and decide who will fill each role; begin discussing designs
2/3: Bring in all materials for building in class during PBL time. 2/21: Final demonstration |
The ProcessStep 1: Decide who will fill each position on your team.
Step 2: Begin investigating possible designs for your marble roller coaster. Step 3: Decide which materials you will use (which do you have and which do you need to find? Who will be in charge of this?) Step 4: Construct your roller coaster. Step 5: Name your roller coaster. Step 6: Perform test runs to ensure consistency of the run and stability of the structure. Step 7: Once your model is finalized, decide which three runs you will use to determine speed, which four sections you will use to describe energy transfer, and which section you will use to determine velocity. Step 8: Perform your calculations and describe energy transfer. Step 9: Celebrate! Requirements1) The run, from beginning to end, must be AT LEAST 8 seconds in duration.
2) Once you do the initial push or drop, you may not touch your marble again until the run is done! 3) Nothing ridiculous or dangerous can be used! (No water, fire, blades, etc.) 4) Each student is responsible for their own task, but collaboration is encouraged. 5) In addition to creating the roller coaster, each student will turn in a paper with the following information: a) A sketch of your three selected runs with speed determined b) A sketch of your four selected runs with energy transfer described in full, well-written sentences. c) A sketch of the one section you selected with determined velocity d) Answers to the following questions: i) What was your assigned role in this project? ii) What was the biggest obstacle you faced in performing your duty? iii) What was the most enjoyable part of this project for you? iv) Did everybody contribute their part to this assignment or did some people do more than others? (Be specific.) v) On a scale of 1 (not at all) -10 (very), how difficult was this? vi) On a scale of 1 (not at all) - 10 (very), how fun was this? vii) What would you recommend I change about this project? |
