Objective

By the end of this lesson, the student will understand the basics of internet domains and how domain names are resolved into IP addresses. They will also learn how to use simple programming concepts to manipulate strings and numbers.

Materials and Prep

• Paper and pencil for notes and exercises
• A computer or tablet with internet access
• Basic knowledge of what a domain name is
• Understanding of simple string manipulation concepts (like concatenation)

Activities

• Domain Name Exploration: The student will research and write down the purpose of different domain extensions (like .com, .org, .net). They will present their findings to you.

• String Manipulation Game: Using paper, the student will create a series of strings using letters, numbers, and symbols. Then, they will practice concatenating these strings to form new words or phrases.

• IP Address Hunt: The student will learn how to use a website to find the IP address of a domain name they choose. They will document their process and share it with you.

Talking Points

• "A domain name is like an address for a website. Just like you need an address to find someone's house, computers need a domain name to find websites."
• "When you type a domain name into your browser, the computer uses a system called DNS (Domain Name System) to find the corresponding IP address. It's like looking up a phone number in a directory!"
• "String manipulation is a fun way to play with text. By combining letters and numbers, you can create unique identifiers or messages."
• "Finding the IP address of a domain name helps you understand how the internet connects different computers. It's like knowing the exact location of a friend's house!"
