Initial Failures

During the project, we faced a couple of initial failures that In the beginning, instead of letting the beans germinate in dark, we put all of them under direct glaring sunlight. This caused moulds to grow on the cotton and around the seeds, preventing some of them from growing.

So we learnt from our mistake and planted a whole new set of beans; this time in the darkness [in the cabinets in classroom]. But yet some of the beans did not germinate for they were already dead. We instead of planting only 15 seeds, this time we had 24, filling up the entire Ferrero Rocher box. Thus, we had a greater chance of having more germinated beans to be experimented on.

We grew beans in trays with partitions to seperate the different beans which we watered with different ph-level water





Things we have gone through as a group

Throughout this project, we have faced many challenges, one of which was when we were not able to agree on the same thing. We could not make a decision on what type of plants we should base our experiment on and what kind and how much acid was needed for our project. This led to many disputes and debates on our different opinions. Finally, after much discussion and the help of internet resources, we could finally come to the conclusion that using sulphuric acid with the difference of 0.002 molars for each solution of acid was the best choice. We also decided that green beans was the most efficient and fair way to find out about the effects of acid on plants. Although we had many disputes among us, we were able to put them aside and did our best to complete our work while keeping the importance of this project in mind. This helped us concentrate on what we were doing and it set us on a mindset to complete our work with high quality and efficiency.

What we have summarised and planned

Finalised Research Topic

The Effect of Acid Rain on Plants in the Equatorial Rainforest

As our research advanced, we realised that we did not have that much time to collect and grow plants from the equatorial rainforest to experiment on them. Also, we did not have the financial capability to buy and purchase such plants. Thus, as a result, we decided to experiment on green beans, a plant which is more affordable and available everywhere. Furthermore, it DOES grow in equatorial countries. To satisfy everyone's constant asking of the question, "Why only experiment on one plant?" I would like to redirect your attention to this blog post. In our Research Topic, it is clearly stated that we want to investigate THE EFFECT OF ACID RAIN on plants in the Equatorial Rainforest. As such, we are more concerned on the EFFECT of acid rain on plants and not the DIFFERENT EFFECTS ON DIFFERENT PLANTS. I hope this clears that up.

Research Topic 2

The Effects of Acid Rain on the Plants in the Equatorial Rainforest


With further research on the topic, we have decided to further refine our research topic to something more relatable to us. Specifically, we decided to research on the effects of Acid Rain on the Plants in the Equatorial Rainforestsomething geographically closer to us. As such, by doing so, we would be able to have a greater impact from our research. We would be able to collect our data and implement possible solutions to places around us, allowing us to see a greater impact or change in the environment around us. The mind map below shows some of the various plants we researched on.

Research Topic


The effects of acid rain on the plants in the environment

We found out that the main source is sulphur dioxide and nitrogen oxide in the atmosphere. And that natural, unpolluted rainwater actually has a pH of about 5.6, which is acidic. Most acid rain deposition ranges from pH 4.3 to 5.0. The acidity of rainwater comes from the natural presence of carbon dioxide, nitric oxide and sulphur oxide that could be found in the lowest layer of the atmosphere.

The types of plants in the environment, mostly rain-forests, are: Pine, Maple trees (which are weak; brittle), creepers/vines in general near ground level (which are weak and soft)

The most Equatorial Rain-forests affected by acid rain is the Congo rainforest of Africa. With it falling throughout the year with levels comparable to acid rain falling in Europe and North America.
According to sources, African fires were the world's leading contributor to pollution coming from the burning of vegetation. African savanna fires are so extensive, he said, that they pump three times more gases and particles into the air than all the fires set by farmers and settlers in South America, including the dramatic fires of the Amazon.

21st Century Problems (Extreme poverty)

Extreme poverty all around the world is a great problem right now. many people out there are starving, who lack of clean drinking water. According to statistics, 2 to 3 billion people live in conditions of extreme poverty. Most of these environments have lack of sanitations. The unhygienic surroundings makes the spread of deadly diseases quick, and they might kill a lot of people. Many people might suffer from diseases that kill them, or some that would affect them for generations. Throughout the years, the difference between rich and poor is becoming ever more extreme. More and more people have access to clean drinking water, have healthy and clean food, have hygienic houses to comfortably settle into. However, there are also increasingly more and more people who have not even tried to drink a drop of pure clean water. More and more who have not are one full course meal in one single day.

Many charities and movements exsists to help out the people suffering from extreme poverty. There are people who donate a huge sum of money to these people to provide shelter, clean water, clean food etc. Many people has also gone to those people to help them clean up the place, fix a clean water filter into their water source etc etc.

These children are food deprived.
