Unit Objectives

By the end of this unit, students will be able to:

1. Name and identify the senses (sight, sound, touch, smell, taste).
2. Name and identify the sense organs (eyes, ears, skin, nose, tongue).
3. Identify different stimuli that affect the senses.

Week-by-Week Breakdown

Week 1: Introduction to the Senses

Day 1: What Are Our Senses?

• Objective: Students will understand what the five senses are and why they are important.
• Key Vocabulary: Senses, sight, smell, taste, hearing, touch.
• Materials:
  • Large colorful poster of the five senses.
  • Sunglasses, hand mirrors, feathers, bells, lemons, flowers.
• Activities:
  1. Start with an interactive storytelling session: A character tries to figure out how to explore the world through senses. Use props (flowers for smell, bells for sound, etc.).
  2. Introduce the five senses through gestures and repetitive chants: “I use my eyes to see, my ears to hear, my hands to touch, my tongue to taste, and my nose to smell!”
  3. Class discussion: “What would the world be like if we didn’t have one of these senses?”
  4. Independent drawing: Ask students to draw a picture of themselves exploring the world using the senses shown on the poster.

Day 2-5: Focus on Sight (Sense 1)

• Objective: Students will be able to describe sight as a sense and identify their eyes as the sensory organ.
• Activities:
  • Story Exploration: Read a book that heavily relies on color and imagery, e.g., Brown Bear, Brown Bear, What Do You See?.
  • Demonstration: Use a flashlight in a dimly lit room to show how light helps us see. Discuss how blindfolds block sight.
  • Play “I Spy”: Have students use descriptive words to identify objects in the room.
  • Art Activity: Use magnifying glasses to examine small items like leaves or fabric. Then have students draw what they observe.

Week 2: Focus on Hearing (Sense 2)

Objective: Students will identify hearing as a sense and learn that ears are the sensory organs for this sense.

• Activities:
  • Sound Explorers: Pass around objects like bells, shakers, and wooden blocks. Create a sound quiz: Play sounds and ask students to identify them (train whistles, birds chirping, water dripping).
  • Quiet Time Game: Have students cover their eyes and listen to sounds in the classroom. Afterward, discuss what they heard.
  • Music Exploration: Create simple rhythms with claps, then have students echo them. Discuss how music makes them feel and why rhythm is important.

---

Week 3: Focus on Smell (Sense 3)

Objective: Students will explore the sense of smell and identify how their noses help them recognize it.

• Activities:
  • Scent Jars Activity: Create jars with different scents (vanilla, orange peels, peppermint, onion, soap). Let students guess the scent and connect it to a real-world experience.
  • Story Connection: Share The Sweet Smell of Christmas by Patricia Scarry. Discuss how smells are linked to special memories.
  • Reflective Art: Ask students to draw an event or object they associate with a particular smell.

---

Week 4: Focus on Taste (Sense 4)

Objective: Students will discover how their tongue helps them taste.

• Activities:
  • Taste Exploration: Provide small samples of sweet (honey), salty (crackers), sour (lemon), and bitter (unsweetened cocoa). Discuss which parts of their tongue "feel" each taste.
  • Chart Preferences: Create a class graph of favorite tastes and discuss patterns.
  • Creative Activity: Pretend to be chefs and design an imaginary meal that incorporates all four tastes. Draw it!

---

Week 5: Focus on Touch (Sense 5)

Objective: Students will explore the sense of touch and identify their skin as a sensory organ.

• Activities:
  • Texture Stations: Set up tables with different textures (cotton, sandpaper, slime, ice, warm objects). Have students describe how each texture feels.
  • Guess the Object: Blindfold a student and let them touch an object to guess what it is.
  • Paint with Ice or Sand: Discuss how texture changes the way art feels on paper.

---

Weeks 6-7: Integration of the Senses

Objective: Students will demonstrate how multiple senses work together to interpret the world.

Activities:

• Outdoor Sensory Walk: Take the class outside with notebooks. Have them sketch, touch various objects, listen closely, and smell scents in nature.
• Role Play: Create a “Senses Detective” game where students solve mysteries using different senses (e.g., “Which sense tells us it’s lunch time?”).
• Class Experiment: Blindfold students one by one and ask them to identify objects using only smell and touch together (e.g., lemons, sponges).
• Culminating Project: Create a giant mural titled “What We Learn Through Our Senses.” Assign groups of students to paint sections representing each sense.

Assessment

1. Oral Check-in: Call on students throughout lessons to explain which sense they’re using and what organ helps them connect to that sense.
2. Worksheets: Provide simple matching worksheets, where students match pictures of objects to the sense used to identify them.
3. Final Presentation: In week 7, students share their favorite activity from the unit and explain which senses they used during that activity.
4. Teacher Observation: Track participation and understanding during discussions, activities, and hands-on experiments.

Reflection for Teachers

• Did students actively engage in each activity?
• Were some senses more relatable or easier for them to identify?
• How can you link this unit to other areas of learning, like art and physical education, in the future?

This holistic, hands-on unit invites students to become young scientists, encouraging curiosity and meaningful exploration of their world!
