Q20256 :	I have a vegetable garden in school and would like to make compost after doing weeding - how do I do that?
Q19918 :	Could you please explain the whole process of the carbon cycle? And please explain the fossil fuel part in more details. Thank you!
Q19883 :	Is there really a hole in the ozone layer?
Q19831 :	I visit Singapore regularly and have notice that there are very, very few stars in the sky although the city appears to be a good, dark city. Why is this? Singapore residents tell me that as recent as 10 years ago there were many more stars. Is it purely an ambient light issue because the country has grown or is it something else?

Q19451 :	I am currently doing a project on the teaching plan for the P6 topic on population and community. I would like to use the Ecogarden at the Singapore Science Centre for enrichment programmes. Can you tell me what is there in the Ecogarden that I can use to teach the concept on population and community and allow the children to be able to infer from the activity on the concept? Thanks.
Q19403 :	What would happen to an ecosystem if (a) all its decomposers and detritus feeders were eliminated or (b) all its producers were eliminated?

Q19128 :	From what I have learnt some time ago in school, if you put ice cubes in a glass and topped to the brim with water, the water will not overflow when the ice finally melts. If this is so, why will there be massive flooding if icebergs do melt due to global warming?
Q19103 :	How do I transform a school pond into a lively pond community with pond skaters, backswimmers, etc? The current pond has a concrete base and does not have any pond animals or common water plants (except for a few fishes and some hydrilla). Can I just purchase the plants and will they be able to survive in the pond? How do I introduce pond animals into the habitat?
Q19066 :	Could you please fill me in on the details of building a simple self-sustainable mini ecosystem, with living organisms such as shrimps and plants, which is able to illustrate the water cycle clearly. This is for a Science project. Any suggestions will be greatly appreciated. Thank you.

Q18940 :	I'm currently doing a project on this bird and require as much information as possible relating to this bird. Found in Singapore, this bird is called the 'robin'. I'm having a lot of difficulty looking for information about its ecology. What's its scientific name? Why has the number decline though the years? Is there a conservation programme on this bird?
Q18875 :	Does a population consist of 1 or more organisms or is a population a group of organisms?

Q16450 :	What are the disadvantages of pesticides?
Q15033 :	I want to know the effects of excess detergent added to the water. And also, what is the volume of detergent needed to cause an effective water pollution (e.g. Eutripication)?
Q13696 :	What happens eventually to household refuse after it has been thrown into the refuse bin or down the chute?
Q12084 :	I am a seaman and I sail on oil tankers. I know these days scientists use remote sensing for the detection of oil spill. Now I am wondering how far they can already go, which projects have been made or are still going on and if their information can be used in court?
Q11791 :	How do I know which cleaning items available in the supermarkets would pollute the environment?
Q10985 :	Can you give me some information on the process of decomposition of the human body, please?
Q10662 :	What are the benefits of snakes?
Q10174 :	I always hear friends saying that living near to seaside or seawater the metallic materials will tend to rust faster. If this is true, my understanding of conditions for rusting such as present of oxygen and water does not seem to explain this phenomenon at all. What are the reasons that seawater and sea breeze cause the metallic materials to rust faster?
Q9913 :	Can you tell me more about pond community?
Q9862 :	What are the insects on the back of some ladybirds?
Q9817 :	What are the ways of recycling, reusing and reducing plastics? Thanks.
Q9796 :	Can I put leaded fuel in a car designed to run on unleaded fuel, which has a catalytic converter?
Q9316 :	What is the effect of oil on water plants? By statistics, all the types of water plants (floating, partially submerged and submerged) give negative results when starch test is carried out. This made me jump to the conclusion that they are dead. So, may I know what are some of the reasons that lead to the death of these water plants? Is it through that the oil blocks up the xylem or just that the plants are not able to take in water? Thank you.
