Caring for Our Skin, Nose, and TongueActivities & Teaching Strategies
Active learning helps students internalize protective habits by linking abstract concepts to concrete, sensory experiences. When students physically practice hand washing or taste foods, they build memory pathways that connect hygiene actions to health outcomes.
Learning Objectives
- 1Explain how washing hands removes germs to protect the sense of touch and overall health.
- 2Compare methods of protecting skin from the sun with methods of protecting eyes from bright light.
- 3Analyze the importance of brushing teeth for maintaining a healthy tongue and sense of taste.
- 4Identify specific actions that keep skin, nose, and tongue clean and healthy.

Stations Rotation: Hygiene Heroes
Create three stations: hand washing with soap timers and glitter germs, sunscreen application on paper skin models, and tooth brushing with oversized models and floss. Groups rotate every 10 minutes, drawing before-and-after pictures. Discuss findings as a class.
Prepare & details
Explain how washing hands protects our sense of touch and overall health.
Facilitation Tip: During the Station Rotation, circulate to prompt students to explain their cleaning steps aloud, reinforcing procedural language.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Role-Play: Sun Smart Challenge
Divide class into pairs to act out sun exposure scenarios: one applies protection, the other does not, using props like hats and lotion. Switch roles and vote on safest choices. Chart class preferences.
Prepare & details
Compare how protecting our skin from the sun is similar to protecting our eyes.
Facilitation Tip: For the Sun Smart Challenge, provide sample UV index cards to help students justify their protection choices in role-plays.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Taste Test Experiment
Students brush teeth models then taste strong flavors like lemon on crackers before and after simulated plaque (yogurt). Record taste intensity on scales. Share how clean tongues detect better.
Prepare & details
Analyze the importance of brushing our teeth for our sense of taste.
Facilitation Tip: In the Taste Test Experiment, ask students to record predictions before tasting to build anticipation and focus.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Nose Sense Sort
Provide safe scents in jars; students sniff through clean vs. dusty cloths, sorting by intensity. Clean noses with tissues between trials. Graph results to compare.

Teaching This Topic
Teachers should model hygiene routines precisely and use visual timers for tasks like hand washing to build consistency. Avoid rushing; allow time for students to feel textures, smells, and tastes. Research suggests that combining tactile and visual cues strengthens retention of hygiene habits better than verbal instruction alone.
What to Expect
Students will demonstrate understanding by explaining how hygiene practices protect their senses, naming tools like sunscreen or toothbrushes, and applying their knowledge in role-plays or experiments. Success looks like confident, accurate discussions and careful use of materials during activities.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring the Role-Play: Sun Smart Challenge, watch for students who assume sunscreen is only needed on sunny days.
What to Teach Instead
Use the UV index cards provided in the activity to show students that UV rays are present even on cooler or cloudy days. Have groups debate whether their characters need protection, then refer to the cards to correct assumptions.
Common MisconceptionDuring the Taste Test Experiment, watch for students who believe brushing teeth is only for appearance.
What to Teach Instead
Before tasting, ask students to predict how their tongue feels after eating sweet or sour foods. After cleaning their tongue with a clean toothbrush, have them retaste and compare sensations, using their notes to link cleanliness to taste sensitivity.
Common MisconceptionDuring the Station Rotation: Hygiene Heroes, watch for students who think germs on hands do not affect nose or tongue.
What to Teach Instead
Use the glitter germ demo at this station to show visible transfer from hands to face models. Students should trace the path of glitter during role-plays, then wash their hands and observe the reduction in glitter, linking this to fewer germs reaching their senses.
Assessment Ideas
After the Station Rotation: Hygiene Heroes, ask students to draw one protection method for skin, nose, or tongue, label it, and explain to a partner how it keeps their senses safe.
During the Role-Play: Sun Smart Challenge, pose the question, 'Why do we need protection even when it’s not hot?' Guide students to connect UV rays to skin damage and sense protection.
After the Taste Test Experiment, provide slips for students to write two things they learned about keeping their tongue or nose healthy, focusing on how hygiene affects taste and smell.
Extensions & Scaffolding
- Challenge early finishers to design a comic strip showing how germs move from hands to face and how washing stops them.
- Scaffolding for struggling students: Provide picture cards of hygiene steps to sequence during the Station Rotation.
- Deeper exploration: Invite students to test different sunscreen SPFs on “skin” samples (paper with UV beads) to observe protection differences.
Key Vocabulary
| germs | Tiny living things, too small to see, that can make us sick if they get into our bodies. |
| hygiene | Practices like washing hands and brushing teeth that keep our bodies clean and help prevent illness. |
| sunscreen | A lotion or spray applied to the skin to protect it from the sun's harmful ultraviolet (UV) rays. |
| plaque | A sticky film of bacteria that forms on teeth and can cause tooth decay if not brushed away. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
