Highways of the Sea Lab Report Instructions: In the Highways of the Sea Lab, you will chart the traveling shoes and predict how ocean currents move. Record your findings below. You will submit your completed lab report. (30 points possible) Name and Title : Include your name, teacher’s name, date, and name of lab. Madelyn Dehnel, Mr. Jagow, Highways of the Sea Lab Report Objective(s) : What was the main purpose of the lab? In this investigation, the goal is to create a map showing the locations where Nike shoes were lost and found in the ocean. Hypothesis : (2 points) This should be a prediction that can be tested. You may use the if/then format to write your hypothesis. If the ocean currents change, it will result in objects being carried in different directions. Procedure : (8 points) On the map below, locate and mark the locations of shoes provided in the data table. You may print your map and mark it by hand or copy it to a program to edit. Label each data point in chronological order from 1 to 11 on the map, and connect the data points with arrows. Unless Otherwise Noted All Content © 2023 Florida Virtual School.

Data : Conclusion : (20 points) 1. Define the following terms: (2 points) a. Current: A current refers to the movement of ocean water in a specific direction. It can be thought of as a flow or stream of water that travels through the ocean. b. Gyre: A gyre is a type of rotating ocean current. It forms when the surface waters of the ocean are affected by the combined forces of wind and the Earth's rotation. 2. Using the map and the data points, what can you conclude about the general pathway the shoes took? (2 points) It can be concluded that the shoes traveled a significant Unless Otherwise Noted All Content © 2023 Florida Virtual School.

distance from their initial location and gradually moved towards the north. This means that the shoes were carried by ocean currents that moved them in a northerly direction. 3. Compare the pathway of the shoes to the map showing the major surface currents in the Pacific. Which current(s) did the shoes most likely encounter? Add these to your map above. (2 points) The shoes most likely encountered the red, warm currents. 4. Which data point is an outlier? What may have happened to this batch of shoes? (2 points) It is likely that the first coordinate stands out as being significantly different from the other coordinates. This could suggest that the shoes may have hopped onto another ocean current due to the presence of an ocean gyre. 5. How fast did the shoes travel? (4 points) a. From where the shoes spilled (48°N, 161°W) to where they first made landfall (49°N, 126°W), how many kilometers did they travel? How many days did they take to travel that distance? (You can use November 30 as the date found). What was their rate of travel in kilometers per hour? Kilometers: 2557 Days traveled: 187 Rate of travel in Kilometers per hour: 1.75 km/hr From where the shoes spilled (48°N, 161°W) to where they were found in 1996 (54°N, 133°W), how many kilometers did they travel? How many days did they take to travel that distance (use April 30 as the date found)? What was their rate of travel in kilometers per hour? Kilometers: 2052 Days traveled: 338 Rate of travel in kilometers per hour: 3.95 km/hr 6. The shoes traveled faster than the rubber ducks and bath toys. Propose a hypothesis to explain why the shoes traveled faster and develop a plan to test your prediction. (2 points) Hypothesis: if the shoes sink into the ocean water, then the currents will carry them in a faster and different direction. To test this hypothesis, one could conduct an experiment using a pool and a pool jet. 7. The shoes floated low in the water, while the ducks floated high in the water. How could this fact have changed the course and speed of both the shoes and the ducks? (2 points) This fact changed the course and speed of both the shoes and ducks because they both have different densities. 8. Give a possible explanation why some shoes drifted northward along the coast while others drifted southward. (2 points) Shoes drifted northward and some drifted southward due to the speed of the ocean's currents, which caused the shoes to move in different directions. 9. Your friend has invited you onto her family’s boat for a day of fishing. After lunch on the boat, your friend wants to throw a bag of trash overboard. After researching the impact currents have on objects, explain what you would do in this situation and why. (2 points) I would advise my friend against throwing trash Unless Otherwise Noted All Content © 2023 Florida Virtual School. FlexPoint Education Cloud™ is a trademark of Florida Virtual School.

overboard by explaining that it is a harmful action because the ocean currents can carry the trash to areas where animals live, potentially causing harm or even death to their species.
