LAJOM, John Froilan C. General Biology 2
S11-08 Reflection Paper


For the biology exhibit, the one that captivates me is the research about the milkfish and tilapia in Taal, Batangas. It captures my attention because it is very timely; we frequently eat tilapia for lunch or dinner, so it made me curious if we should continue to eat tilapia. They researched if parasites were the one responsible for the diseases or death of the tilapia and milkfish and to know the correlation of the psychochemical properties on parasites burden that may affect the growth and quality of milkfish and tilapia. Observation was made among all the samples that they captured, internally and externally. They weren't able to see parasites but able to see cysts, nodules and enlargement of intestines. This alarmed me but they said that it doesn't really give harm to us. It will just affect the quality of the fish. But then again, there will be a possible significant correlation between the fish growth in weight and length to psychochemical analysis of water. This also affects the quantity of catch of the fishermen that affect their livelihood that is quite alarming.
For the exhibit at the Ground Floor, the one that captures my attention is the reversed vending machine. From the name itself, it's quite intriguing. I'm surprised when the exhibitor started to put bottle or aluminium can in the opening 'door' of the machine because it gives off corresponding amount of money. The machine only accept bottles and cans that weigh 11-17g so to attain this, the exhibitor pour in liquid to the bottles and cans. Why it captivates me is that not only we benefit through the money that we are able to get, but also the environment because the bottles and cans that will be collected will be then sent to manufacturing establishments that will recycle them.
