Personally, I think it is huge for kids to understand a specific protocol that has a standard port number assigned to it: E.g. HTTP - port 80, HTTPS - port 443, FTP - ports 20 and 21, etc. There are maybe 10-15 ports with which kids should be intimately familiar.

TCP/IP has a little thing called "whois". This protocol identifies the owner of a particular website. This may not be the best reconnaissance tool for Ma and Pa Kettle shops as they go through companies like Wix or GoDaddy. These ISPs handles everything for them. HOWEVER, with bigger companies, the whois record will show the address, contact info, and DNS boxes (!!) that are responsible for name resolution. This can be a great start for recon.

I would bring in a phone book and have the kids look things up and discuss the information found in a phone book. We would then discuss what information appears on an envelope or package you are mailing. We could compare and contrast information in an IP address and how DNS fits in.

Merge the concept of Website names/numbers with that of cell phone names/numbers. Perfect chance to practice learning their parent's phone number and learn that websites also have phone numbers. Literacy, i.e. practicing letter names and sounds is naturally embedded in this activity, used as a tool to an end, instead of an isolated lesson.

Have an ongoing competition for making a conceptual model or visual aid for thinking about OSI (e.g. we had the castle comparison today - it would me useful to have more based on different areas of student interest— sports, movies, books, famous pieces of architecture, the human body, etc.)

My kids love to watch You Tube movies hosted by Eli the IT Guy. The link below is an hour-long movie that goes over the basics of TCP/IP and subnet masks. Highly recommended.

# data[].attributes.body
I think I will use the videos to help students begin to understand how the internet works. I also want to have my students use Aspire to understand network.

# data[].attributes.body
Have them do a project building a network including placement of all appliances like firewalls, SIEM devices, IDS, Etc. Explaining their choices and why

# data[].attributes.body
Have students tell me home phone numbers - a standard in K-2nd, and then help them understand that computers all have contact numbers too.  We protect our home phone numbers from strangers, so we need to protect our computer contact numbers too.

# data[].attributes.body
Great intro: have students hand phones to each other

I would like to explore aspire with my cyber patriot students and compare with packet tracer and concepts from the curriculum

We will physically recreate the internet and develop our own internet protocols. Once we establish those, we'll add hackers and security breaks and discuss cybersecurity.

# data[].attributes.body
I plan to show the videos that we looked at today and make a fun type of quiz to check for understanding, like Kahoot.

# data[].attributes.body
I would use the castle as a check for understanding once I taught the layers.

I really like the idea of gamifying network development.  I need to play around with it more though.

# data[].attributes.body
I plan to use the castle as a starting point.  Build background, bring in literacy, physical aspects, example of forts, castles, etc.  Then, have kids build a castle through makerspace.  Talk about different layers. Then, progress deeper and deeper into network security.  Defensive and offensive examples.

# data[].attributes.body
I would use Terminal/Command to introduce network concepts/code by having students ping networked computers and their favorite websites.

# data[].attributes.body
I want to further explore the Apsire program and have students work through that to learn how to set up a network amongst many other skills.

# data[].attributes.body
I plan to use the RubbyDucky method to have my students talk through the issues they're having with coding, a device, network, etc.

# data[].attributes.body
Talk about the steps they go through logging in and out, as well as the consequences of not logging out.  Why does it "lock people out" of the computer if they forget to log out?

# data[].attributes.body
I will use this a s a good introduction to build background They can't understand the threats to their data if they don't now the system it is traveling through.

First Video  - How does information Travel Over a Network?  Great video to explain the binary code and use of equipment to send information over a network.  She defined bit, byte, megabyte and downloading time/capacity.  She explained that we can use electricity, but while it is less expensive, it has a problem with signal loss at a distance.  Light or fiber optics, has no signal loss, and has cables running all over the world, it is expensive.  The third possibility is radio.  Radio translates the sounds to  1's and 0's, but has a distance issue, so it probably needs to connect with some kind of wire transport form.

An excellent 4 minute video overview that shares a very brief history of the origin of the internet. The military was tasked to figure out how to build a communication system that would survive a nuclear attack - called the Advanced Research Projects Agency Network (ARPANET).
Eventually communication strands were grouped into networks, which grew upon themselves creating a mesh of blocks exploding into what we now call the Internet.

A great introduction video to how information travels. This would be great to use before students are doing any kind of networking, or even as a first week activity. Using the video with "EdPuzzle" would be great! This is a source where you can embed questions in to the video and it will make students answer the question before they can continue viewing the video.

IP (Internet Protocol) Addresses are a number given to every web accessible device and is used like a home address to find it on a network. DNS (Domain Name system) associates a corresponding web address with the IP address. Great intro to how students' devices are all connected in a network, like houses in a neighborhood or town (IP addresses). DNS would be actual neighborhood or town names.

This will be a great introduction to OSI layer 1.  A really accessible video about how the internet is physically laid out. Discusses different materials data can travel over (wire, fiber optic, radio). A small, useful section on how information is organized: into bits and bytes.

# data[].attributes.body
This is a great video to use to introduce the topics of IP Addresses and DNS and how it works.
