1 Integrated Science 2015 Amusement Park Challenge Purpose: A land developer in Snohomish has decided to build an amusement park on farm land near the river. They have all their permits in place. Now they need to select a ride designer, so they are accepting bids for various designs. The team that produces the best design within budget will win a lucrative contract. You have assembled a team of engineers to help design a coaster/zipline that meets the developer s requirements. You want your coaster to be taller than the record holding Kingda Ka in New Jersey which is 139 meters tall. You are aiming for 140 to 150 meters tall. [The model will be on a 1:100 scale, so 150 meters will be 1.50 meters or 150 cm on your model.] The land available for the structure is 60 X 80 meters. You will present your model and an inventory of all material costs on the due date. The amusement park design team will consider all of the following when comparing your coaster proposal with the other group s proposals. See the rubric for point value. Total materials cost on your inventory. [Cheaper is better.] Length of ride. [Longer is better.] Reliability of ride. [Marble makes it safely to the end every time.] Interesting features. [Loops, funnels, turns, uphill sections.] Technical features work. [Starting switch, marble catcher, zipline transfer.] Requirements: 1. Height between 140 and 150 centimeters tall. 2. Minimum ride time of 10 seconds. 3. Average speed for 5 trials calculated. 4. Minimum of 5 different elements to provide interest 1 or more loops 4 or more turns 1 or more funnels 1 or more uphill sections Zipline Element. [+10 bonus points if zipline is NOT at begining or end. ] Extra Credit: Marble is stopped by magnet at the end of the ride. (You will use a magnetic marble for this option.) 5. Working electromagnet start switch. [Must be designed so the person starting it does NOT have to touch the battery or bare wire with their fingers.] 6. Ride name displayed with decorations to match your groups proposed theme. 7. Catcher bucket at the end to stop the marble. [Not applicable if doing extra credit.] 8. Group Self-Assessment completed X 11 inch diagram showing *energy transformations. Kinetic <--> Potential X 11 inch diagram *labeling physics concepts. [See List of required concepts] *See attached papers O Ryan

3 Energy Transformations Sketch a model of your amusement park ride. Identify at least 4 examples of energy transformation. o Kinetic Energy Potential Energy o At least one calculation of kinetic energy. KE = ½ MV 2 o At least on calculation of potential energy. PE = MGH Identify the type of kinetic or potential energy. o Chemical Energy Electrical Energy Magnetic Gravitational Mechanical

4 Calculations Demonstrate how you used mathematical functions to describe and evaluate your amusement park ride. You must have at least one calculation for each of the following: Concept Formula Example from your ride. Label on diagram. Newton s 2 nd Law A Kinetic Energy B Potential Energy C Speed D

5 Conclusion 1. What forces are experienced in both your roller coaster and zip lines motion? 2. How will you transport the marble along the zipline? 3. How will you transfer the marble to and from the zipline? 4. How will frictional forces affect your design? 5. How will gravitational forces affect your design? 6. Where was potential energy and kinetic energy greatest in your ride? 7. What applications in business, industry or the real world relate to a zip line? The Presentation Create a PowerPoint presentation summarizing your research and design that includes: Title slide that contains a name for your zip line trolley system and the names of your team members. Slides that document the Engineering Design Process including: o The challenge statement (What was the purpose of your project? Hint: Read purpose.) o Constraints for the project (Identify the 3 main constraints.) o Criteria for your project (Identify 3 5 criteria.) Your team s design solution. o Photo or detailed sketch of design o Three reasons why you chose that design over other idea generated by your team. The lab design tests and processes used to evaluate your design; provide evidence from your tests/results that support your explanations. o the lab design results including data tables and calculations o Revisions to the design incorporated in your final product, o Explanations of how your design meets or does not meet the challenge. Make a 3 to 5 minute team presentation of your PowerPoint in which every team member presents at least two slides.

7 Science Standards Checklist EALR 3 Application Unit Concept I can work collaboratively with other students to generate ideas for solving a problem. Mastery (+,, ) What I know Questions/ What I don t know Application I can identify constraints for solving a problem. (Constraints are limitations imposed like money, materials or time.) I can identify criteria for solving a problem. (Criteria are the standards used to measure success. For example, in the Amusement Park Ride Project, the ride needs to be 10 seconds or longer.) I can research the problem and use the information collected to generate possible solutions. I can compare alternatives to choose the best solution to a problem. I can create a model or drawing of the final design and devise a way to test it. I can redesign the solution when my tests don t produced the needed result. (For example, if you were designing a device that collected rainwater from roofs and it didn t work very well, you could redesign it and present it to your peers.) I can use mathematical functions to calculate and describe the forces and motion in my Amusement Park ride. I can apply my knowledge of the electromagnetic force by designing a device that affects the motion of the marble in the ride. (An example is using electricity to start, stop or slow down the movement of the marble in the ride.) Mastery Symbols + = Confident, I can do this! = I can do this but I need to work on it = I am still struggling O Ryan
