Materials needed
- 2 container of equal sizes
- 1 small hydroponic plantation
- 4 pieces of white paper
- Blue tack
Steps:
1. a slit is cut in both containers. this is done so we can measure the temperature.
2. a bluetack is placed to cover the hole so as to prevent air in the container from escaping.
3. placed a white sheet of paper on top and below the containers
4. placed the plants we grown on one of the containers
5. measure the temperature of the two containers with a thermometer daily
This is our experiment:
The container with the plant is called Container A and the other container is called Container B.
To keep the experiment fair and get reliable results, we kept everything constant except that Container A has a small hydroponic plantation while Container B do not have.
Our hypothesis is the container with the small hydroponic vegetation have a lower temperature than the container without the hydroponic vegetation.
Data collected:
We concluded that Conatiner A has a lower temperature than Container B as the plants take in carbon dioxide during photosynthesis and replace it with oxygen. Container B has a higher temperature as carbon dioxide traps heat and the container gets warmer. However in the morning the temperature of both containers are very similar their temperatures are very close. IN the afternoon where there is a stronger sunlight, the plants photosynthesis and absorb more carbon dioxide.
Carbon dioxide is one of the greenhouse gases, so if every building in Singapore has a hydroponic vegetation on their rooftop, there will be lesse carbon dioxide and lower down the temperature. This is also a solution for Global warming.
Difficulties faced while planting most of the plants died thus we used green beans for our experiment.
