Instincts vs. Learned Behaviors — 5E Lesson (50 minutes)

Key Vocabulary

• Instinct: A behavior an animal is born knowing how to do.
• Learned behavior: A behavior an animal gains from practice or experience.
• Stimulus: A change that causes a response (like a sound or light).
• Response: What an animal does after a stimulus.

Materials (common classroom)

• Index cards or slips of paper (20+)
• Markers, tape
• Stopwatch or timer (phones or classroom clock)
• Notebook paper and pencils
• Ruler (for quick demo), small paper ball (tightly wadded scrap)

Brief Intro (read aloud): Animals act in different ways. Some actions are built‑in and happen without being taught. We call these instincts. Other actions are learned by watching, practicing, or being taught. Today we will sort behaviors and test how practice changes performance.

Common Misconceptions

• “All fast reactions are instincts.” (Some quick reactions are learned.)
• “If a behavior happens when young, it must be learned.” (Many instincts start early in life.)
• “Humans only learn; animals only have instincts.” (Both humans and animals can have instincts and learned behaviors.)

Demo: Ruler Drop Reaction (pairs)

1. Partner A holds a ruler at the 0 mark above Partner B’s open fingers (thumb and index) without touching.
2. Without warning, Partner A drops the ruler. Partner B tries to catch it as fast as possible.
3. Repeat 3 times and note if catches improve with practice.

Explain — Mini‑Lesson (10 min)

Short Reading (Grade 5 level): An instinct is a behavior an animal is born ready to do. Birds build nests without lessons. Sea turtles crawl toward the ocean right after hatching. A learned behavior is a behavior gained from experience. A dog learns to fetch. A child learns to type. Both types of behavior help animals survive. Instincts get animals started. Learning helps animals improve or adjust to their environment.

   Answer: B

Elaborate — Hands‑On Lab (20 min)

Lab Question

How does practice affect performance, and how is that different from an instinct?

Part A — Behavior Sort (≈10 min)

1. Place 12–16 behavior cards (teacher or student‑made) face up on a table.
2. In teams of 3–4, sort each card into “Instinct” or “Learned Behavior.”
3. For three cards, write a short “because” sentence that explains your choice.

Part B — Practice‑Makes‑Better Trial (≈10 min)

Purpose: Model a learned behavior improving with practice.

1. Use tape to make a simple paper “maze” path on a desk (start → finish).
2. Roll a small paper ball or eraser cap along the path using a pencil as the “pusher.”
3. Time three trials. Try to beat your time by using what you learn each round.
4. Record data and describe what changed across trials.

Evaluate — Exit Ticket (5 min)

1. MC: Which is an instinct?
   A. Horse learning a trick
   B. Child playing basketball
   C. Bird building a nest
   D. Dog rolling over on command
2. MC: Which is most likely a learned behavior?
   A. Baby crying
   B. Salmon swimming upstream
   C. Owl hunting at night
   D. Child using a keyboard
3. MC: A sudden shadow makes a lizard freeze. The freeze is the ______.
   A. instinct
   B. stimulus
   C. response
   D. learned behavior
4. Constructed Response (1–2 sentences): Explain how practice changed your team’s maze performance today. Was that instinct or learning? Why?
5. MC: Which statement is true?
   A. Instincts always need a teacher.
   B. Learned behaviors come from experience and practice.
   C. Instincts and learned behaviors are the same.
   D. Learned behaviors are inherited at birth.

Answer Key

Teacher Wrap‑Up (1–2 min)

• Ask 2 students to share one instinct example and one learned example from the card sort.
• Connect to survival: instincts help animals start life; learning helps them adapt.
