Lab Name: Ride(s) involved: Bigger Coaster = More Riders? Coasters throughout the Park Key Question: Student Tech Requirements: Stop Watch Activity Directions: Using the following tables, you are going to collect data about the coasters at Hersheypark. As a train leaves the station or passes a particular point of reference, start the stopwatch. Record the cumulative time in seconds (do not stop the watch) as the next six trains dispatch or pass the particular point of reference. The number of trains will be the independent variable. The dependent variable will be the cumulative number of passengers that have left the station. So in addition to keeping the time, you will need to count the number of people riding in each train to keep a running total of the number of people that have ridden the coaster.

Mini-Geocaching inside Hersheypark You will need a longitude/latitude app or a GPS reader. Due to the variety of apps, all waypoints have been recorded both as degrees ( ) minutes ( ) seconds ( ), and degrees ( ) minutes ( ) with decimals. See the end of this activity if you wish to learn how to convert seconds into decimal minutes. Note: mini-geocaching requires precise measurements with little change in the degree and minute units of measure. Our first stop is to ride a horse while following the path of a conic section. Record your waypoint location: Record your location: N W Now it is off to a little game of cat and mouse. Travel NE to: N 40 17 34 ( 40 17.567 ) W 76 39 18 ( 76 39.300 ) Look due EAST and upward. What two water rides do see listed on the same sign? It s not far to the next stop. Go east to the far entrance of the Rube Goldberg water machine. Record your waypoint location: Record your location: N W Back up the hill for a restful ride. Your ride over the park will take you outside the park to the eastern most point of the ride. Be attentive, the ride does not stop at this location. There was a time, many years ago, when visitors to this building were treated to the smell of chocolate mixing in very large vats. Record your location: N W 26
Over the river and through the valley to our next stop we go. Here live the live residents of Hersheypark. Travel to: N 40 17 16 ( 40 17.267 ) W 76 39 04 ( 76 39.067 ) How do you measure up? Take a photo with the sign. Our final stop leads us to the entrance of an attraction that Chicken Little may never ride. Is the sky really falling or does it just feel that way on the ride? Record your location: N W Name the ride. Well done! We hope your trip around the Park was enjoyable. --------------------------------------------------------------------------------------------------- Degrees, minutes and seconds are similar to hours, minutes and seconds. A minute is one sixtieth of a degree. A second is one sixtieth of a minute. For this activity, to convert a second to a decimal part of a minute divide the seconds by 60. To convert the decimal part of a minute to a second multiply by 60. 27

Smart phone, stopwatch 41
Pre-Activity: Since the concept of work is not directly a part of the AP curriculum, it is an application of integration. It would be good to talk about work in order to get a feel for what it is and if the answer to the question below makes sense. How much is a Joule? How much work is required to lift a book from the floor to a desk? How much work is required to lift a loaded elevator up 2 stories? Activity Directions: Use your smart phone to retrieve the following information: Mass of train: Number of passengers: 1. Measure the time for the train to accelerate from rest to the point just prior to its ascent (when the train achieves its maximum velocity). t = 2. At t = 0, the train has an acceleration of 3.5 g s (34.3 m 2 ). At the time you found above, the train is moving at 1.5 g s (14.7 m 2 ). Use this information to create an exponential s equation that models the train s acceleration. This can be achieved through the STAT menu of a TI graphing calculator. s 3.

Record the time, in seconds, for each ride in the table below. Track Time around / lap time (seconds) Classic Cars Speedway 43
2. Velocity is another word for speed. When you calculate velocity, you are answering the question How far did I go, and how long did it take me to get there? The formula to calculate velocity is V = d or Velocity = distance t time Write your lap times in the table below. The distance for each track is provided. Use this information to calculate your velocity for each track. Track Classic Cars Speedway Time around / lap time Length of Track Velocity (feet/second) 1,167 feet 1,076 feet 3. For cars in the United States, velocity is usually described in miles/hour (or mph). For the Classic Cars track and Speedway track, convert your feet/second velocity to miles/hour on your own or following these steps below. Classic Cars Velocity (ft/sec) 1 second feet 60 seconds 60 minutes 1 mile miles x 1 minute x 1 hour x feet = hour 5,280 44

If you had to get back to your school in 30 minutes, how fast (in miles/hour) would you have to drive? Post-Activity: Graph your velocity information from the Speedway track. Time (in seconds) on x axis, distance (in feet) on y axis. Do you think this graph tells a true story of your trip on the speedway? Why or why not? **Hersheypark graph of the speedway s velocity (will be provided in next update to this guide) Ride data / elements: actual graph of speed vs. time for 1 lap of each of the Classic and Speedway tracks Discuss the similarities and differences you see. What reasons might exist for the differences? 45
Real-Life Racing: The final race of the 2011 NASCAR Sprint Cup Series was run at Homestead-Miami Speedway on Nov. 20, 2011. In that race, the fastest lap was run by Carl Edwards, with a speed of 171.838 mph. Convert this speed from miles/hour to feet/second. If one lap of the Speedway is 1.5 miles long, how many seconds did it take Carl to complete the fastest lap of the race? NASCAR teams and officials measure lap times to the 1000 th of a second, and speeds to the 1000 th of mph. Why do you think this might be? Lab Name: Ride(s) involved: Wave Swinger Wave Swinger Key Question: Student Tech Requirements: Smart phone, stopwatch, altimeter Pre-Activity: Discuss how to use an altimeter. Activity Directions: Use your smart phone to retrieve the following information: Radius of the outer ring: 1. Measure the period of rotation. T = 46
2. Calculate the tangential speed v t for the outer ring. ds Useful formulas: s r= θ, v t = dt 3. Use an altimeter to measure the angle from the ground to one of the seats on the outer ring. θ = 4. Calculate the height of the seat using the above angle. Estimate both the horizontal distance on the ground from the seat to your position and the height at which you are holding the altimeter. 5. Suppose an outer ring rider s shoe fell off their foot. Find the velocity with which the shoe hits the ground. Ride data / elements: Wave Swinger ENGLISH METRIC Radius of outer ring 30 6 9.3 m 47
Lab Name: Ride(s) involved: When Will It Happen? Entire Park Key Question: Student Tech Requirements: Activity Directions: Determine the number of people described in each situation Problem 1: If each seat on the Tidal Force seats 4 people and each seat is half full every time a boat leaves. How many boats will have dispatched before boat with the 48 th person feels the force? Problem 2: If you are standing in line for Fahrenheit and there are 42 people in front of you. How many FULL trains will leave BEFORE the train with you in it leaves? Problem 3: You enter the line for the Wave Swinger just as a group of people are exiting. You notice there are 100 people in front of you. How many times will the ride start, and be completely full, BEFORE you get on the ride? Problem 4: You notice that the line for the Whip is not too long, only 24 people. You do not get on the ride because all of the seats are occupied, but none by more than 2 people. Determine how many of the seats are filled with 2 people and how many with just 1 person. 48
Lab Name: Ride(s) involved: ZooAmerica Animals in their Habitats ZooAmerica various habitats Key Question: Student Tech Requirements: Activity Directions: There are 5 habitats in ZooAmerica: Northlands, Big Sky Country, Eastern Woodlands, The Great Southwest, and Southern Swamps. 1) Visit at least 3 habitats, and count the number of different types of animals you see in each of the following categories. Then convert each count into a percent of that habitat s total. Northlands Big Sky Country Animal Category # of different types % of total Animal Category # of different types % of total Birds Birds Reptiles Reptiles Mammals Mammals Fish Fish Other Other TOTAL TOTAL 49
Eastern Woodlands Animal Category Birds # of different types % of total Reptiles Mammals Fish Other TOTAL The Great Southwest Southern Swamps Animal Category # of different types % of total Animal Category # of different types % of total Birds Birds Reptiles Reptiles Mammals Mammals Fish Fish Other Other TOTAL TOTAL 50
2) Using the percentages you calculated, make a pie chart for each habitat. 3) Which habitat has the highest percentage of reptiles? Which habitat has the highest percentage of birds? Which habitat has the highest percentage of mammals? 4) Is the habitat with the highest number of different types of reptiles also the habitat with the highest percentage of reptiles? If not, explain what causes the difference. 5) Which habitat(s) have no reptiles at all? Why do you think that might be? 2017 Hershey Entertainment & Resorts Company.
