2. Classify nice smells, bad smells, and distinct tastes.
3. State why tasting unknown items can be dangerous.

Presentation Steps

1. Introduction to Smell: Spray air freshener. Explain that we use our nose to smell things.

5. Class Activity: Blindfold a volunteer to identify foods by smell and taste using safe items like oranges and sugar.

📝 Short Board Note for Pupils

WEEK 3
TOPIC: THE SENSES (PART 3) - SMELL AND TASTE

1. We use our nose to smell things around us.

2. There are nice smells (flowers, food) and bad smells (rubbish, smoke).

3. We use our tongue to taste different things.

The four (4) basic tastes are:

• Sweet (Sugar, honey)
• Sour (Lime, green mango)
• Bitter (Bitterleaf, medicine)
• Salty (Kitchen salt)

Safety Rule: Never taste or smell unknown things because they can harm you.

Evaluation & Assessment

• What do we use to taste our food?
• Name two things that have a bad smell.
• Why must we never taste chemical liquids we find in a bottle?
