Ch 8: Instructions for Life
 Make a new header page for the
chapter
 I will give you chapter goals and a
rubric on Monday.
 Update your Table of Contents
 Your notebooks will be graded this
chapter, so make it neat.
Engage: Just the Fax p. 396
 Learning Target: I can decipher a
binary code and discover how only two
symbols can code for a large amount of
information.
 Update your TOC
Engage: Just the Fax p. 396
 Work with your partner and think of as
many different types of codes as you
can that can be used to relay messages.
 How are codes unique?
 Why do people use codes?
Engage: Just the Fax p. 396
You are going to each get a coded
message and your job will be to
decode it.
Follow P&P #1-7
When you have cracked your code,
write the message on the board.
Complete R&C #1-5
Engage: Just the Fax p. 396
Class list of decoded words:
Protein
Hemoglobin Actin
Hormone
Glucagon
Myosin
Venom
Lactase
Insulin
Antibodies
Fibroin
Collagen
Enzyme
Keratin
Amylase

R&C #1: Would you have been able
to read the message if guidelines
were not provided for you?
Explain.
Without knowing the rule, it is difficult to
know where to start decoding the message.
There are many ways to go about it, and guess
and check would be difficult without some
kind of guidance.

R&C #2: Digital coding only uses 2
symbols (0’s and 1’s). How many
different words are on the class list?
Could the same code be used to make
more words? Explain.
There are 15 words on the class list, which were
made using only 2 symbols. These same 2
symbols could code for an almost infinite
number of words because there are many,
many possible arrangements of 0’s and 1’s.

R&C #3: The letter e is part of many
words. Give 3 examples of how the
addition of an “e” at the end of a word
alters its meaning. How is this similar
to a fax machine or a bar code?
Stat – state; rat – rate; fat – fate; hat – hate; mat –
mate; us – use; war – ware;
The placement of the 0’s and 1’s in the fax code
changes the meaning of the word, just as the
addition of an “e” changes the meaning of a word.

R&C #4: Create a concept map using
all of the words in the class list. Use
linking words to show what they have
in common.
Protein
Hemoglobin Actin
Hormone
Glucagon
Myosin
Venom
Lactase
Insulin
Antibodies
Fibroin
Collagen
Enzyme
Keratin
Amylase

R&C #5: You should have gathered the
following information about your
word:
What is it?
What is its function?
Where is it found?
What is it made of?
Why is it important?
