Activity 01
Experiment: Glitter Germs
Apply lotion and glitter to students' hands to mimic germs, then have pairs shake hands or touch surfaces. Wash hands with soap and water at sinks, comparing results with and without soap. Observe residue under bright light and record findings on charts.
Justify why washing hands is an important habit.
Facilitation TipDuring Glitter Germs, remind students to rub their palms together gently to mimic real-life germ spread, avoiding vigorous shaking that distorts the simulation.
What to look forAsk students to hold up one finger for 'true' and two fingers for 'false' in response to statements like: 'Germs can spread when you share toys.' or 'Washing hands only removes dirt, not germs.' Observe student responses to gauge understanding.

Activity 02
Role Play: Daily Routines
Assign scenarios like after playtime or before lunch. In pairs, students act out correct handwashing steps using timers and songs, then switch roles. Class discusses and votes on best demonstrations.
Explain how germs spread and how hygiene stops them.
Facilitation TipIn Role Play, provide props like toy toothbrushes and soap bars to anchor routines in familiar objects, making abstract steps feel real.
What to look forProvide each student with a small piece of paper. Ask them to draw one picture showing a good hygiene habit and write one word that describes why it is important (e.g., 'healthy', 'clean', 'safe').

Activity 03
Poster Design: Hygiene Heroes
Groups draw sequenced steps for handwashing or teeth brushing, label with reasons, and add slogans. Present posters to the class, explaining how each step stops germs. Display in classroom for reference.
Construct a poster to teach others about good hygiene.
Facilitation TipFor Poster Design, limit colors to two per student to ensure focus on hygiene messages rather than decoration.
What to look forPose the question: 'Imagine your friend forgot to wash their hands before eating. What might happen, and what would you tell them?' Facilitate a brief class discussion, listening for explanations of germ spread and the benefits of hygiene.

Activity 04
Relay: Proper Brushing
Set up stations with models, brushes, and timers. Teams relay through brushing steps on models, singing a 2-minute song. Debrief on missed steps and retry for improvement.
Justify why washing hands is an important habit.
Facilitation TipUse a stopwatch during Proper Brushing relays to standardize timing and build consistency in technique.
What to look forAsk students to hold up one finger for 'true' and two fingers for 'false' in response to statements like: 'Germs can spread when you share toys.' or 'Washing hands only removes dirt, not germs.' Observe student responses to gauge understanding.

Generate Complete Lesson→A few notes on teaching this unit
Teach hygiene habits by linking scientific evidence to daily actions. Research shows that students retain habits better when they connect cause and effect, such as seeing soap’s role in disrupting germs during experiments. Avoid assuming prior knowledge; instead, build understanding through repeated, scaffolded practice in different contexts. Model behaviors explicitly and correct errors immediately to prevent misconceptions from forming.
Success looks like students explaining why habits matter and demonstrating proper techniques, such as using soap for 20 seconds or brushing all surfaces of their teeth. They should describe germs as tiny, invisible threats and connect washing to staying healthy, using language from the activities.
Watch Out for These Misconceptions
During Glitter Germs, watch for students who believe glitter represents dirt rather than germs.
Pause the activity and ask, 'What does the glitter represent? How is it like real germs?' Use the activity’s materials to guide students toward understanding that glitter symbolises invisible germs that spread through touch.
During Relays: Proper Brushing, watch for students who think water alone removes all germs from hands.
Have students compare two results: one from washing hands with water only and one with soap and water. Ask them to describe the differences in cleanliness to reinforce the role of soap in disrupting germs.
During Role Play: Daily Routines, watch for students who believe brushing teeth once a day is sufficient.
Use the role play to demonstrate the recommended brushing duration with a timer. Ask students to time each other’s brushing and discuss why two minutes matter, linking it to the activity’s structure.
