Grade 5 Physical And Health Education Outdoor And Recreational Activities – Food Preservation Notes
Physical & Health Education — Outdoor & Recreational Activities
Subtopic: Food Preservation (Age 10, Kenya)
When we go outdoors (picnics, hikes, camping) or help at home, food can go bad quickly. Learning safe ways to keep food fresh prevents sickness and saves money. We will look at easy, safe methods you can use in Kenya.
Specific Learning Outcomes (SLOs)
- Identify common methods of food preservation used in Kenya (sun-drying, smoking, salting, cooling, airtight storage).
- Explain, in simple terms, why food spoils and how preservation slows spoilage (heat, moisture, insects, bacteria).
- Demonstrate two safe, simple preservation techniques (e.g., sun-drying fruit, using an airtight container) during an outdoor activity.
- Practice hand-washing and basic hygiene when handling food outdoors to prevent foodborne illness.
- Plan a simple food pack for a day trip that keeps food safe and nutritious (choice, packing, cooling).
Common Preservation Methods & How to Explain to 10‑year‑olds
Remove water from food so germs cannot grow. Good for mango slices, tomatoes, maize and beans when sunny.
Steps: slice thinly → place on clean tray or rack → cover with fine net to keep flies off → turn pieces during the day → store when dry.
Safety: wash hands/food first; use clean cloth; do not dry meat outdoors without supervision.
Smoke helps dry and flavor fish and meat. Common in Kenya for fish like tilapia and for meat jerky.
Note: Only done by adults or with adult supervision and proper smokehouses.
Salt draws out water. That is why salted fish lasts longer. Pickling (using vinegar) helps keep vegetables like carrots or cucumbers for short times.
Safety: keep jars clean; store pickles in cool place.
Use cool boxes with ice packs for milk, yoghurt, cooked food and meat on day trips. Cold slows bacterial growth.
Tip: place raw and cooked foods in separate containers to avoid cross‑contamination.
Use clean jars, tins or plastic boxes to stop insects and dirt. Good for maize, beans and roasted snacks.
Simple Visual: How Sun-Drying Works
- Wash and slice food thinly.
- Place on clean tray in sun, cover with net/clean cloth to keep flies off.
- Turn during the day. Bring in at night.
- Store in dry airtight container when fully dry.
Suggested Learning Experiences (for classroom, outdoors and home)
1. Hands-on: Sun-dry Mango or Tomato Slices (Group activity)
Materials: clean knife (adult use), chopping board, tray or wire rack, clean net or muslin cloth, bowl, labels.
Steps for learners:
- Wash hands and fruit. An adult helps slice into thin pieces.
- Lay pieces on the tray in sunlight, cover with net to keep flies away.
- Observe and note changes each hour: colour, feel, smell.
- After two–three days (or when dry), put in clean jar and label with date.
Learning point: Show how water leaves the fruit and it becomes harder for germs to grow.
2. Make a Simple Cardboard Solar Dryer (Teacher-led)
Materials: cardboard box, black paper, clear plastic sheet, mesh, tape, scissors (adult), small trays.
Create a box with a clear top, black inside to absorb heat, and mesh shelves. Use to dry small fruit slices safely and keep dust/flies out.
Safety: adults cut and assemble; do not place flammable items near the dryer.
3. Pack-a-Day-Trip Challenge (Outdoor learning)
Task: In groups, plan and pack a safe lunch for a school hike. Include which preservation methods you used and why.
Criteria to check: use of cool box or insulated container, use of airtight containers, separation of raw and cooked food, inclusion of water, hygiene kit (soap, towel).
4. Safety & Hygiene Role Play (Class activity)
Students act out what can go wrong if hands are dirty, food is left in sun too long without cover, or raw meat touches cooked food. Teacher guides correct actions.
Assessment Ideas (for the teacher)
- Observe students during activities: did they wash hands, cover food, label jars?
- Short quiz: match methods to examples (e.g., tilapia → smoking).
- Group poster: draw one preservation method and write 2 safety rules.
- Practical task: each group shows a packed lunch for a hike and explains choices.
Teacher Notes & Kenyan Context Tips
- Use local foods: mangoes, tomatoes, maize (corn), beans, dried cassava, tilapia — students will relate better.
- Respect community methods: many families dry or smoke fish/meat. Discuss pros and safety (adult supervision for smoking).
- Emphasize safe water and hand washing to prevent sickness — connect to local water sources and clean-up practices.
- When outdoors, remind students not to taste food left exposed and to return leftovers to proper containers.
Vocabulary (simple)
Spoil — when food goes bad; Preserve — keep food from spoiling; Drying, Smoking, Salt, Cool box, Airtight.
- Always wash hands with soap before touching food.
- Only adults use knives or build burners/smokers.
- Cover food from flies and dust when outside.
- Use cool boxes for milk, yoghurt and cooked foods on trips.
- Do not eat anything left on the ground or uncovered for a long time.
Use these activities during PHE lessons and school outings to teach life skills that keep food safe, healthy and enjoyable for outdoor living and recreation.
