Your Senses & Your Brain: How You Take In the World

Students explore the five senses and learn they all do the same job — gathering information and sending it to the brain, which makes sense of it and tells the body how to respond.

The Lesson · 5E Model

45 minutes, five moves

Tap any phase to open the teacher moves and student actions.

1

Engage — Sense Detective

5 min

Close your eyes — what can you still sense?

👩‍🏫 Teacher Moves

  • Have students close their eyes and notice senses.
  • List what they can still sense.
  • Set the goal: senses and the brain.

🎒 Student Actions

  • Notice sounds, smells, touch.
  • Name the senses used.
  • Predict who’s in charge.
2

Explore — Explore the Senses

12 min

Students investigate the explorer.

👩‍🏫 Teacher Moves

  • Send students to the Senses Explorer.
  • Have them log each sense + organ.
  • Ask how info reaches the brain.

🎒 Student Actions

  • Tap each sense.
  • Record the organ.
  • Trace info to the brain.
3

Explain — Sense to Brain to Response

12 min

Teacher explains.

👩‍🏫 Teacher Moves

  • Show senses gather info → nerves → brain.
  • Brain makes sense of it → body responds.
  • Give an example (hot stove → pull hand).

🎒 Student Actions

  • Explain the info pathway.
  • Describe a response.
  • Name the brain’s job.
4

Elaborate — Senses Team Up

11 min

Show senses working together.

👩‍🏫 Teacher Moves

  • Show how senses combine (taste + smell).
  • Explain reactions (flinch, blink).
  • Ask how animals use senses to survive.

🎒 Student Actions

  • Explain two senses combining.
  • Describe a quick reaction.
  • Compare to an animal’s senses.
5

Evaluate — Exit Ticket

5 min

Three quick checks.

👩‍🏫 Teacher Moves

  • Hand out the exit ticket.
  • Look for gather → brain → respond.
  • Collect as formative data.

🎒 Student Actions

  • Name the senses.
  • Explain the brain’s role.
  • Describe a response.
Standards Alignment

Built to the standards you report on

NGSS
4-LS1-2

Use a model to describe that animals receive different types of information through their senses, process it in the brain, and respond in different ways.

NGSS
4-LS1-1

Construct an argument that animals have internal and external structures that support survival.

CCSS
RI.4.7

Interpret information presented visually and explain how it contributes to understanding.

CCSS
W.4.2

Write informative/explanatory texts to convey ideas clearly.

Differentiation

One lesson, every learner

Multilingual Learners

Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
Name the five senses.
Sight, hearing, smell, taste, and touch.
QUESTION 2
What does the brain do with the information your senses gather?
It processes (makes sense of) the signals and tells the body how to respond.
QUESTION 3
You touch something hot and quickly pull your hand away. Explain how your senses and brain worked.
Your skin sensed the heat and sent a signal to your brain, which quickly told your muscles to pull your hand away.

Going deeper? Build a senses station lab.

Set up five stations (something to see, hear, smell, taste, and touch) and have students record which sense and organ each uses, and how the brain responds. A printable station log is in the Science library.
