Many solutions have been used to TRANSFEr information.
[CER] DISCUSSION QUESTION:
What is the best solution to transfer information safely over long distances? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / Investigate
1. Classroom Communicator - Successfully send a secret digitized message across the room to your partner.
2. Let's Get Digital - use a grid of 1's and 0's representing black and white to send information about a picture. 3. Ancient Text - use Morse code to send a text. 4. Binary Baubles - find out that all kinds of information can be stored with different combinations of just two choices. |
/ Iii / Level Up!
During this lesson you will learn more about how instruments transmit and detect waves to extend human senses including:
- Lenses can be used to make eyeglasses, telescopes, or microscopes in order to extend what can be seen.
- The design of such instruments is based on understanding how the path of light bends at the surface of a lens.
- Digitized information (e.g., the pixels of a picture) can be stored for future recovery or transmitted over long distances without significant degradation.
- High-tech devices, such as computers or cell phones, can receive and decode information—convert it from digitized form to voice—and vice versa.

Using distance and accuracy data of the final transmitted information from your class as evidence, evaluate each of the following solutions to determine if some ways of transmitting information are more effective than others:

/ V / Knowledge Check
A group of students were asked to generate solutions to safely transfer information across the room using only materials available in the classroom. One group decided to use drums to send coded information through sound waves. Another group chose to use a grid of 1's and 0's representing black and white to send information about a picture, and the last group used Morse code to send a text.
