The following links provide background on the topics covered in this lesson:
Start with a VERY brief class discussion: How does the Internet work?
Journal: what is the difference between the Internet and a browser? How are they connected?
(Use the optional Student Handout for Unit 3 Lesson 1 if desired to guide all of the activities in this lesson. There is an answer key to the student handout for teachers to use as well.)
Demonstrate, using the following resources, how the Internet has grown from the small ARPANET system to what it is today.
Students read the following sections from the "Blown to Bits" book (Online book link: http://www.bitsbook.com/wp-content/uploads/2008/12/B2B_3.pdf):

Students create a diagram of how an email might travel from its start point to the end point.
Demonstrate how to test bandwidth using the following sites:
Students should use the tool to come up with a question that can be answered by the tool. Students write an analysis that asks the question, answers the question and provide proof of why the answer is correct by providing screenshots of the tool in their report. ( http://www.akamai.com/html/technology/nui/industry/ ) or http://www.internetlivestats.com/ for live Internet stats.
(Note: Students can possibly start this assignment in class, but will likely need to complete as homework.)
In this activity, students will each share one thing they have learned from this lesson. This can be done in several ways depending on time constraints or disabilities. All students should participate in some way before leaving the classroom.
Using a real-time network tool that measures the number of views per minute, students generate a question that can be answered using this tool. They will then collect the data and write a report that answers this question. The report should use current real-time screenshots for data and examples. (Note: Students can possibly start this assignment in class, but will likely need to complete as homework.)
