The 3 key takeaways from today's visit are about the reservoirs in Singapore, the treatment process of the NEWater and the technology involved in the process.
2. Name 2 concepts that you have learnt today during the visit.
I have learnt about ultrafiltration and reverse osmosis.
Ultrafiltration uses a "case-like" thing to purify the water.
Reverse osmosis is like a thin string which has a lot of pores that only allow water molecules to pass through.
3. What is the 1 interesting thing that you have learnt today?
The interesting thing that I have learnt today is that if the pores in reverse osmosis is the size of a tennis ball, a water molecule will be like a ping pong ball. A mineral would be a soccer ball. A virus would be the size of a truck and a bacteria would be the size of the water plant.
4. What are the things that you can do to help with water conservation in Singapore?

4. What are the things that you can do to help with water conservation in Singapore?
I can help by carrying out the 3Rs. I can use the water after washing the rice to water the plants.
