Evaluate the claims, evidence, and reasoning behind the idea that electromagnetic radiation can be described either by a wave model or a particle model (quantum theory), and that for some situations one model is more useful than the other.
Clarification Statement: Emphasis is on how the experimental evidence supports the claim and how a theory is generally modified in light of new evidence. Examples of a phenomenon could include resonance, interference, diffraction, and photoelectric effect.
Assessment Boundary: Assessment of the photoelectric effect is limited to qualitative descriptions.

| COSMOS concepts to be used for the lab |
Different communication on the same frequency will interfere with each other.
|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
Students describe the effect of interference on waves. Students use the wifi communications between different laptops to create interference between two different waves.
|
| Short Description and Walk-through of the experiment |
Students communicate on different WiFi channels to see which two channels create the least interference.
|
| Testbed mapping of the experiment |
Students check which combination of channels allows more users with least interference.
