Project-Based Learning – Detailed Guide

---

🔹 Project 1: Mini Rainwater Harvesting Model

Objective: To understand how rainwater can be collected and stored.

Materials Needed:

• Shoebox or cardboard base

• Plastic bottle / small container

• Funnel or paper cone

• Straws or pipes (straws can represent pipes)

• Clay or tape for sealing

• Scissors & glue

Steps:

1. Take a shoebox and imagine it as your house.

2. Cut a sloping roof from cardboard and fix it on the box.

3. Make a hole at the bottom edge of the roof → insert a straw (pipe).

4. Attach the straw to a plastic bottle kept on the side (storage tank).

5. Use a funnel to pour water on the roof → water flows through pipe → collects in the bottle.

6. Decorate and label (Roof → Pipe → Tank).

Assessment:

• Did the model show correct water flow?

• Did the student explain how it helps in saving water?

🔹 Project 2: Water Cycle in a Jar

Objective: To observe evaporation, condensation, and precipitation.

Materials Needed:

• Transparent jar / glass bowl with lid (or zip-lock plastic bag)

• Water (½ cup)

• Small plant or soil (optional)

• Plastic wrap or glass cover

• Sunlight

Steps:

1. Pour some water into the jar.

2. Add soil or a small plant (optional, to show life with water).

3. Cover the jar tightly with plastic wrap or its lid.

4. Place the jar near sunlight or a window.

5. After a few hours/days, observe →

   • Water evaporates and sticks to the cover (condensation).

   • Droplets fall back (precipitation).

6. Record daily observations in a notebook with drawings.

Assessment:

• Did the student notice all 3 stages (evaporation, condensation, precipitation)?

• Did they keep a record with sketches?

🔹 Project 3: Survey on Water Usage at Home/School

Objective: To study how water is used and find ways to save it.

Materials Needed:

• Notebook or chart paper

• Pencil, ruler, crayons

• Support from parents/teachers

Steps:

1. Make a table with 3 columns: Activity, Water Used, Can we reduce it?

2. Observe at home/school for 1–2 days.
   Example: Drinking – 5 litres, Washing clothes – 20 litres, Bathing – 30 litres.

3. Discuss with parents/teachers to estimate water use.

4. Suggest at least 3–4 ideas to save water.
   Example: Use bucket instead of shower, turn off tap while brushing.

5. Present your findings on a chart in class.

Assessment:

• Was the data realistic?

• Did the student suggest useful solutions?

---

🔹 Project 4: Adopt a Water Body (Observation Project)

Objective: To observe life in and around a pond/lake/river.

Materials Needed:

• Observation notebook

• Sketchbook / camera (if allowed)

• Adult/teacher supervision

Steps:

1. Visit a pond, lake, or aquarium (in groups with teacher/parents).

2. Note what you see → fish, frogs, birds, insects, plants.

3. Draw or take photos of at least 3 plants and 3 animals.

4. Observe water quality → Is it clean or dirty? Any plastic waste?

5. Suggest 2–3 ideas to keep the water body clean.

6. Prepare a short report with drawings/sketches.

Assessment:

• Did students correctly identify plants/animals?

• Did they link observation with water conservation?

🔹 Project 5: Design a “Water-Smart School” Blueprint

Objective: To think creatively about water conservation in schools.

Materials Needed:

• Chart paper / drawing sheet

• Scale, crayons/colour pencils

• Optional: cardboard for 3D model

Steps:

1. Imagine a school that saves water.

2. Draw a blueprint (top view) showing:

   • Rainwater harvesting tank

   • Gardens watered by recycled water

   • Soak pits for groundwater recharge

   • Water taps with “turn-off” reminders

   • Drinking water filters

3. Label each part clearly.

4. Optional: Make a 3D model with cardboard boxes and straws.

5. Present your design to the class explaining each feature.

Assessment:

• Was the design practical?

• Did it include at least 3 water-saving methods?
