Product Description
I don't know about you, but when I saw the NGSS Performance Expectation "MS-P4-3: Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals" I had no idea how to teach this to students!! Lucky for me (and YOU!), I found some resources and created this AMAZING one week unit/lesson plans to teach students this standard. I even pooled together some information about digital vs. analog signals in communication in case it is confusing! But please keep in mind that basic knowledge about digital and analog communication is a must! I believe this is why some teachers rated me below 4 stars on the product.

This interactive and engaging approach using a Slinky helps students learn about and understand complex concepts about electromagnetic waves by teaching them through modeling. Its focus is on electromagnetic waves in modern communication technologies such as sending images though a computer. It is a one week lesson plan that should take place after a basic understanding of amplitude, frequency, and wavelength of waves has been achieved. There are 7 activities the students participate in through groups of 4, but each activity can take anywhere from 15 minutes to 45 minutes depending on the length of time the teacher wants to spend on it. Students take on a role such as a transmitter, anchor, receiver, or image generator and model how digital vs. analog signals are sent. This lesson plan is teacher-friendly as it was designed for the teacher to follow through the lesson with the students. It includes background for the teacher, tips, student worksheets and name tags, conclusions for each station, final conclusions, links to YouTube videos needed and an answer key!

Materials per group of 4: one regular metal slinky, one set of name tags (transmitter, anchor, receiver, image generator included), one blindfold, one clipboard, graph paper, pencil, one index card, ruler

Activity 1: Students send their first waves
Activity 2: Students learn the difference between analog and digital
Activity 3: Students send their first "letter"
Activity 4: Students send a higher resolution text
Activity 5: Students read about how a computer creates images
Activity 6: Students learn how gray and color is created
Activity 7: Students learn how movies are sent (Includes a YouTube clip of Star Wars and the video game Halo 3 as part of your instruction!)

This set of plans covers the NGSS Performance Expectation MS-P4-3: Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals. Emphasis is on waves used for communication, including the conversion of binary patterns.
