Number of Sessions to teach the topic 5 - 6 sessions
Educational standards to be addressed
  • CCSS.MATH.CONTENT.6.EE.C.9
    Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
  • CCSS.MATH.CONTENT.7.RP.A.2
    Recognize and represent proportional relationships between quantities.
  • CCSS.MATH.CONTENT.7.EE.B.4
    Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.
COSMOS concepts to be used for the lab Internet service providers (ISP), routing, IP Addresses, traceroutes, response time, route hops.
K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) Teaching ratio, rate, speed and relationship between two quantities/comparing two quantities by determining the hops and ISP of a webpage being searched.
Short Description and Walk-through of the experiment
  1. Day 1 Using the subway map and the google map, students will search places that they will visit using the subway trains and record the number of hops taken with the different options and the time it takes to travel between hops.
  2. Day 2 Students will present and discuss the information gathered from this activity using the graphic organizer provided and share the results to the class using tables, graphs (with correct color and legend) and equations.
  3. Day 3 Using the gnuradio/COSMOS toolkit, the students will perform the experiment on using traceroute to see how traffic is transferred between Internet Service Providers.
  4. Day 4 Students will discuss the similarities and differences of the hops done travelling on the train and the hops happening in a traceroute. Graphic organizers will be shared and will be used to present data.
  5. Day 5 Project:
    • Search their 5 favorite places for summer vacations outside the country and find out the hops using the https://traceroute-online.com/.
  6. Final output of the project will be presented in a powerpoint presentation.
Testbed mapping of the experiment The experiment can be extended by executing it into a COSMOS Toolkit using the traceroute after an activity on the train hops is understood as analogy to these concepts.

Experiment Execution

Press this the START button to open the traceroute application. You can use the following link to find an IP address for a specific country. Follow the instructions on the worksheet to find the distance and the latency for each country.
