Teacher's Guide for Real Time Data Activities

Overview

This multidisciplinary Internet-based learning experience has been designed to expose students to real world problem solving through unique uses of instructional technologies. In this project, students will use real time data from the Internet to track a real ship at sea, determine its destination and predict when it will arrive. In addition, they will have the option of monitoring the weather conditions at sea and predicting when rough weather might impact on the ship's arrival time.These lesson plans has been developed to help you implement this project in your classroom. Each lesson plan has a web site associated with it for students use, handouts, and links to support materials. Besides the traditional parts of the lesson plans (e.g. objectives, materials, procedures, etc.) you will also find suggestions on how to implement the project in a classroom with limited Internet access. The last section of this guide contains suggestions for assessing students who complete the project. It is recommended that you review all of the lesson plans in detail prior to implementing the project in your classroom.

LESSON #1: What's your problem?


Performance Objective: Students will develop a problem statement based on the project story.

Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Introduce the project . Explain to your students that they are going to get a chance to apply some of the things that they have learned in math, science and social studies to a real world problem.
  2. Have students read the story .
  3. LIMITED INTERNET ACCESS STRATEGY : Use the Handout #1 which includes the project story on it. If you have a way of displaying your computer monitor, go to the project web site and access the story. Leave it on the display while the students are reading from the handout.
  4. Hold a class discussion . Ask your students to tell you what they think the problems are and why. Some students might not realize that determining the speed of the ship will be important. If this occurs you may want to have them consider a different but related problem. Ask them to imagine that three friends leave their school to go to the local pizza place. One walks, another takes a bike and the third gets a ride in a car. They all travel the same distance but arrive at very different times. You can then ask them why they arrive at different time, the answer being that the speed they were traveling. You can then ask them that if they know where their ship is located and where it is headed what else would they need to know in order to determine when they will arrive in port? The answer: speed.
  5. Create a common problem statement. Once you have collected responses from everyone, work with them as a class or in groups to develop a problem statement. Have them record their problem statement in the appropriate section of Handout #1: What's your problem? The important aspects of the problem statement are:

Sample Problem Statement : We need to figure out where we are located right now. We also need to find out what place we are heading to and when we will get there. We think that it might be important to also know the speed of the ship so that we can figure out how long it will take to get to port. It will also be important to keep track of the weather in our area in case a bad storm comes that might delay us from getting to our port on time. Homework Suggestion: You can either ask the students to think about what they will need to do to solve the problems they have identified or you can have them work on some practice problems on plotting latitude and longitude coordinates (see Prerequisite Knowledge section in Lesson #2).


LESSON #2: Where on earth are you?


Performance Objective: Students will determine where their ship is located, where it was previously and will plot these positions on a map using latitude and longitude coordinates. Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Prerequisite knowledge. If your students are not familiar with latitude and longitude you should make sure that they understand what latitude and longitude coordinates are and how they can be used to plot points on the surface of the earth prior to this lesson. You will find resources to help you cover this topic in both the "Hands-on Activities" section and the "Reference Material" section off of the project web site.
  2. Selecting an appropriate ship(s) . Since the Stowaway Adventure uses real time data from ships at sea it is important to find a ship which is reporting the right data for use in the activity. Since you are now dealing with real world information you will find that it is not always available (e.g. ship might lose communication capabilities). Thus it is very important to prepare for this lesson just prior to implementing it. To select an appropriate ship or ships follow these steps:
  3. Ship ID Code . Explain to the students that there are thousands of cargo ships in the worlds oceans which transport goods between the continents. Discuss the following:
  4. Locating the Ship .
  5. LIMITED INTERNET ACCESS STRATEGY : Use display system to show the ocean map to the students and explain what the symbols on the map represent. Have them work in groups and have a representative from each group come up to the front of the room and locate the ship on the display. They can return to their group and point out its approximate location on their paper maps. While each group works at the computer the other groups could be working on developing latitude and longitude, map or speed calculation skills. There are worksheets on these topics in the "Reference Materials" section off the main project web site.
  6. Accessing Data from the Ship . Next students will need to access the online database to retrieve data that the ship has submitted over the past couple of days.
  7. LIMITED INTERNET ACCESS STRATEGY : Have the students work in groups and assign a different ship to each group. While each group works that the computer the other groups could be working on developing latitude and longitude, map or speed calculation skills. There are worksheets on these topics in the "Reference Materials" section off the main project web site.

Homework Suggestion: Have the students take home the data they collected and ask them to finish plotting the rest of the data points (at least four previous locations). They should label each point with the date and time that it was recorded. Have them note any information that might help them solve their problems.

LESSON #3: What's your destination?


Performance Objective: Students will plot the location of their ship on their map, determine what direction the ship is headed in and in what city it will dock (port-of-call).

Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Plotting the Ship's Position
  2. Observations and discussions: Ask the students to make some general observations of how the ship is moving. Spend a few minutes going over the questions on Handout #3.
  3. Determine what city or port-of-call you are headed towards
  4. Drawing some conclusions . Once the students have been given some time to record their answers, hold an informal discussion with them to talk about what they have learned so far and how this information can be used to solve the initial problems they outlined. See if they can figure out how to use the information they have collected to answer as many of the initial questions as possible.

Homework Suggestion: Have your students review the problem statement they came up with at the start of the project. Have them answer as many of the initial questions as they can and write them down. In particular they should be able to determine where they are and where they are going. They should also be able to indicate that the speed of the ship is relatively constant.

LESSON #4: Faster than a speeding slug


Performance Objective: Students will determine how far they have traveled between locations, how long it took to travel that distance and the speed of the ship.

Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Prerequisite knowledge . If your students do not have experience calculating the speed of a moving object you should cover this with them prior to this lesson. See the "Hands-on Activities" and "Reference Material" sections for resources that will help you cover this topic.
  2. Go over the homework . Based on the information they had they should have been able to determine the following:
  3. Discuss the next steps . Before going on hold a discussion with the class about what else needs to be calculated. Have them figure out what data they need to collect in order to determine the approximate speed of the ship. Before moving on they should all recognize that they will need to determine the distance the ship has traveled and the time it took to travel that distance in order to calculate the speed of the ship.
  4. Determine distance traveled . The students will now use a web site to calculate the distance the ship has traveled between its two last known locations. Alternatively, you could have them determine the distance traveled by measuring the distance between the points they have plotted on their maps and using the scale on the map to calculate the actual distance traveled. This second method is a good way to practice basic map skills but tends to be less accurate. To calculate the distance traveled using the web follow these steps:
  5. Determining travel time . Have the students look back at Handout #2: Where are earth are you? They should find the time and dates listed next to each set of position coordinates. Have them note and time interval between the current position and previous position #4 . This is the amount of time it took the ship to travel between its previous positions and the current position. Have them record this data on Handout #4: Faster than a speeding slug.
  6. Calculating the speed of the ship . Using a basic speed equation [Speed = Distance/Time] students can now calculate the speed of the ship in miles per hour. Have them make this calculation and record their findings on Handout #4: Faster than a speeding slug. If you want you can then have them calculate the speed in kilometers per hour and nautical miles per hour (knots).

Homework Suggestion : Have students exchange ship data with another group OR get data from another ship. Ask them to do the same calculations they did for their first ship for the second.


LESSON #5: Are we there yet?


Performance Objective: Students will determine how far away they are from port and when they will arrive.

Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Prerequisite Knowledge. As with the last lesson, lesson #5 is best done with students who have experience calculating the speed of moving objects and using the speed of an object to determine how long it will take to travel a known distance.
  2. Determine how many miles (or kilometers) are left in the voyage. The last step is to determine how much distance they have left to travel in the voyage.
  3. Calculate arrival time . Now that students know how fast the ship is moving and how far away they are from their port-of-call they can estimate how long it will take to reach their destination.
  4. Solving the problem . The final activity is to have the students put all of the pieces together and solve all of the problems presented in the original problem statement. On Handout #5 have your students complete the final section. They should re-state the problem statement and describe in their own words how they went about solving it. The final portion should be a solution statement outlining the solutions they came up with for the project.

Sample Solution Statement : After tracking the ship over several time intervals we were able to determine that it is headed to X and is X miles away from the port. Since the ship is traveling at X mph it should take another X hours to get to our destination. This means that we should arrive at approximately X on X. Student calculations should be shown as well. Optional Extension Activity : Since this is real time data coming from real ships the only real method for check to see if the student has picked the correct destination and arrival time is to track the ship until it reaches port. If time allows you can have student track the ship each day until they can determine where it docks and the time it took to arrive in port.


LESSON #6: Rain Delay


Performance Objective: Students will determine what the weather conditions are around their ship and decide if the conditions could impact on their voyage.

Materials:

Procedure: The following steps will help you guide your students through the lesson.
  1. Observing weather satellite images. Students will first view a real time weather satellite image showing cloud cover above the ocean that their ship is located in. Follow these steps:
  2. Observing effects of atmospheric disturbances on the surface of the ocean. It is often hard to determine what effect a given atmospheric disturbance may be having on the surface of the ocean. The following steps will allow students to determine if a storm that they noted the presence of in step #1 is actually a threat to surface ships.
  3. Drawing conclusions . Hold a class discussion and have the students consider and respond to these questions.
