Code.org has lots of incredible resources, including a bunch of videos on computer science topics. Two that are particularly relevant to Wi-Fi are "What Is the Internet?" and "The Internet: Wires, Cables, and Wi-Fi."
There are tons of resources online from NASA, and they are all pretty awesome. Here is one that discusses radio waves and how they are used to communicate with spacecraft. Understanding how radio waves work will help you understand how Wi-Fi works.
University of Southern California (USC) has a site called Illumin created by their students. There is a page on Radio Waves and How they Work. Warning: this site runs an audio program explaining Illumin (and I haven't figured out a way to turn it off other than turning off the speakers on my computer). This page is nice, though. It discusses the differences between AM and FM as well as some other common concepts in radio.
The American Physical Society (APS) has a page dedicated to Hedy Lamarr and George Antheil and their frequency-hopping invention. It even has an image from their patent submission.
Science Buddies has some ideas for Wi-Fi related science experiments that might be good for science fair projects.
Teach Engineering has a one-hour lesson plan for 7th graders on Riding the Radio Waves.
We are all now connected by the Internet, like neurons in a giant brain.
