Teacher Facilitation Guide
Duration
30 MIN
Objective
Identify and explain the 7 characteristics of life and apply them to classify real-world examples.
Audience
9th Grade Biology (Foundational Tier 1)
Approach
Interactive instruction, group classification, and individual assessment.
Why This Matters
"Understanding what defines life lays the foundation for all biology topics; this lesson helps students distinguish living vs. nonliving systems and builds critical thinking skills."
Preparation
10m
Review Vital Signs Slides.
Print Life Lab Worksheets (1 per student).
Print Pulse Check Quizzes.
Arrange desks for small-group collaboration.
Queue the slides and test projector.

Instructional Routine
1
Warm-Up Discussion
5 MIN
Ask students: “What does it mean to be alive?”
List student responses on the whiteboard without judgment.
Introduce the concept of biological standards — specific criteria scientists use to define life.
2
Direct Instruction
10 MIN
Display Vital Signs Slides.
Define each characteristic: organization, metabolism, homeostasis, growth, reproduction, response to stimuli, adaptation.
Provide one real-world example per characteristic (e.g., sweating for homeostasis).
Check for understanding with quick thumbs-up/thumbs-down prompts after each definition.
3
Group Activity
8 MIN
Divide students into groups of 3–4.
Distribute Life Lab Worksheet.
Groups classify scenarios (seed, campfire, virus, smartphone) as living or nonliving.
Circulate to support and ask probing questions: "A fire consumes energy, so why isn't it considered alive?"
4
Exit Ticket Quiz
5 MIN
Hand out Pulse Check Quiz.
Students work individually to identify characteristics in new contexts.
Collect quizzes for formative assessment data.
5
Cool-Down Reflection
2 MIN
Ask students to share one new fact.
Prompt: “Give an example of something you once thought was alive but now know isn’t.”
Reinforce how scientific standards remove ambiguity in biological definitions.

Exploring the 7 Essential Characteristics
Learning Objectives
Identify and define the seven characteristics of life.
Provide real-world examples for each characteristic.
Reflect on why these criteria matter in biological science.
Characteristic 1
Organization
All living things exhibit a complex but ordered structure.
Cells → Organism
Cells
Tissues
Organs
Systems
Organism
Characteristic 2
Metabolism
Living organisms take in energy and materials to power life processes.
Anabolism
Building complex molecules from simpler ones.
Catabolism
Breaking down molecules to release energy.
Characteristic 3
Homeostasis
The ability to maintain a constant internal environment despite external changes.
Temperature
Water Balance
pH Balance
Characteristic 4
Growth & Development
Growth
Increase in size through cell division and enlargement.
Development
Changes in form and function over an organism's life cycle.
Example: Embryo → Juvenile → Adult
Characteristic 5
Reproduction
Producing new individuals of the same species.
Sexual
Two parents provide genetic material, leading to diversity.
Asexual
Single parent produces identical offspring (clones).
Characteristic 6
Response to Stimuli
Detecting and responding to environmental changes.
Light
Temp
Chemicals
Pressure
Characteristic 7
Adaptation
"Heritable traits that enhance survival and reproduction, developed over many generations."
Think: Darwin's Finches | Antibiotic Resistance
