• VOICE LEVELS: Tables 1, 3, 5, and 7
– Why do we use different voice levels 0-4? What
are they? Give an example of when we would
each voice level.
• CLASSWORK: Tables 2, 4, 6, and 8
– How should independent work be completed
differently than partner or group work? What
would be similar about independent, partner, and
group work?
Classifying Organisms
• Turn and Talk (Partner – Voice Level 1)
• Which external structures would you use to
classify these organisms into two groups?
Classifying Organisms

Dichotomous Key - A
tool used in plant or
animal identification.
Using two or more
choices, organisms’
identities are determined
through the process of
eliminating characteristics
that it does not have.
“The Key to Identification”
Partner-read the article. What should our voice
levels be?
As you read, you will work with your partner to
take two-column notes on page _____.

ESSENTIAL QUESTION: How do scientists
use external features to classify and identify
organisms?
OBJECTIVES:
1. Create a biological diagram identifying
major structures of a plant
2. Practice using observations to identify a
species
3. Use a dichotomous key to identify a
native Texas plant species
Finish Reading – POPCORN!!
• Finish reading “The Key to Identification”
• Popcorn Reading Rules:
– Read at least 3 sentences
– Pay attention!
– You can call on someone more than once but not
if they were just reading before you (no pingpong popcorn)
• Crash Course biology: Taxonomy

Using the checked external structures, what
type of animal organism do you predict you
have?
Animal Choices
• Determine which organism is represented by
your observation card.

Introduction to Biological Drawings: Plant Anatomy
Plant features
can be very
complex and
varied (different).
With your table,
discuss some of
the differences in
the leaves shown
to the right.
Biological Diagram: Native Species
1. Title the next page (82) in
your composition book,
“Biological Diagram”
2. Observe your specimen
closely.
3. Create a biological
drawing of your specimen.
4. Follow the dichotomous
key to determine what
species it is.
