| Educational standards to be addressed |
New York State P-12 Science Learning Standards (NGSS)
- MS-PS4-3
Develop a model and use mathematical representations to describe waves that include frequency, wavelength, and how the amplitude of a wave is related to the energy in a wave.
Common Core Standards
- SL.8.5
Integrate multimedia and visual displays into presentations to clarify information, strengthen claims and evidence, and add interest.
- RST.6-8.9
Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text or prepared information on the same topic.

| COSMOS concepts to be used for the lab |
Transmission of electronic data over the INTERNET using different transmission speeds.
|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
Different methods of connecting to the INTERNET have different data transmission speeds that go along with each method. Using simulations on the COSMOS Technology Toolkit students will be able to observe the time it takes to transmit data using each method and then calculate the data transmission speed for each method.
|
| Short Description and Walk-through of the experiment |
Students will be introduced to the 5 main methods of connecting to the INTERNET today with a slide show. Students will then work in groups to run a series of simulations on the COSMOS Technology toolkit to see the time it takes to transmit a specific amount of data. Students will then calculate the data transfer speed for each INTERNET connection method. Following that they will construct a bar graph of the different times observed for each transmission. Finally, students will answer questions relating to the activity they have just completed.
|
| Testbed mapping of the experiment |
The experiment can be extended by executing it into a testbed (ORBIT/COSMOS) through the following steps:
This experiment can also be done on the WITEST, ORBIT, and COSMOS testbeds to give real time observations.
