🧪 Three Ways to Save Water

Objective: Find three ways your family can save water at home.

🔒 Safety Notice: Ask an adult to supervise. Do not taste any experiment materials. Do not use dangerous chemicals. Follow the instructions carefully and wash your hands afterwards.

🔮 Step 1 — Predict first!

Your prediction

Which room do you predict uses the most water in your home?

🧰 Materials

Paper, pencil, and a walk around your home

📋 Instructions

1. Walk around your home with an adult and note every place water is used.
2. For each place, think of one way to use less water.
3. Choose the three best ideas and try them for a week!

⚙️ The variables

🔧 What we change

The water-saving habits your family tries

📏 What we measure

How much water is used (e.g. shorter showers)

⚖️ What stays the same

The same family and the same home

📊 Step 2 — Collect your data

Enter your own measurements below — the chart draws itself as you type. If your experiment does not have measurements, record what you saw in the notes box.

🔍 Step 3 — Prediction vs observation

💡 The science behind it

Singapore has limited fresh water, so saving water matters. Every drop saved at the tap, in the shower and in the washing machine adds up — and recycled water (NEWater) helps too!

🏁 Conclusion

Share your three ideas with your family. Applying science to real life is what scientists do!
