The student will learn a dance and identify the pattern, then create a dance routine in both repeating and growing patterns. Students will also understand and identify simple loops.
The students will collaboratively create a dance using the Dance Party Hour of Code Activity.
This interactive lesson teaches middle school students about how information is delivered via the internet. Students will review/ be introduced to vocabulary words, gain an understanding of packets and servers, and be challenged with different internet connectivity (Wi-Fi, cable, DSL, and Fiber Optic) as they work together as a team to deliver a message to another IP address.
This lesson has been slightly adapted from the original version from Code.org. All the links and copyright information are included in the lesson. The teacher is able to use the original or the premade materials from this document.
Have fun!
Students will be introduced to the term algorithm while reading the story of Humpty Dumpty. Students will develop an algorithm or step by step sequence of instructions for putting Humpty Dumpty back together again.

Lesson 8: Cybersecurity - Simple Encryption
From the website:
OVERVIEW
"In this lesson, students are introduced to the need for encryption and simple techniques for breaking (or cracking) secret messages. Students try their own hand at cracking a message encoded with the classic Caesar cipher and also a Random Substitution Cipher. Students should become well-acquainted with idea that in an age of powerful computational tools, techniques of encryption will need to be more sophisticated. The most important aspect of this lesson is to understand how and why encryption plays a role in all of our lives every day on the Internet, and that making good encryption is not trivial. Students will get their feet wet with understanding the considerations that must go into making strong encryption in the face of powerful computational tools that can be used to crack it. The need for secrecy when sending bits over the Internet is important for anyone using the Internet."
OBJECTIVE
"Explain why encryption is an important need for everyday life on the Internet.
Crack a message encrypted with a Caesar cipher using a Caesar Cipher Widget
Crack a message encrypted with random substitution using Frequency Analysis
Explain the weaknesses and security flaws of substitution ciphers"
The lesson is mapped out for teachers. It is easy to follow and includes vocabulary to cover, links to the necessary materials, and a teaching guide with background information, tips, and prompts.
AGENDA
Warm Up (10 min)
Classic Encryption - The Caesar Cipher
Activity (35 min)
Part 1 - Crack a Caesar Cipher
Part 2 - Crack a Random Substitution Cipher
Wrap Up (15 min)
Video: Encryption and Public Keys
