Introduction Humans release carbon dioxide because of their needs. The carbon dioxide that is released then goes into the ocean and ocean acidification takes place. My species is a Java Fern. The scientific name of Java Fern is Microsorum Pteropus. In a food chain, the trophic level it falls under is producer. My group researched how acidic water affects the height and weight of Java Fern. We were comparing the difference between our plants being in normal water verses slightly more acidic water.
Hypothesis & Research Q For my group’s experiment, our investigating question was “how does ocean acidification affect Java Fern’s height and weight?” Our hypothesis was “if the water is more acidic, then the Java Fern’s height and weight will decrease”.
Dependent variable- The acidity of the water.
M e t h o d s
Independent variable- Growth of Java Fern. Length of study- 10 days Control group- 1 Java Fern growing in standard water water and we were measuring weight and height. Treatment group- 1 Java Fern growing in slightly more acidic water and we were measuring weight and height as well. Pre data- Collected by measuring height and checking weight on 1st day. Post data- Collected by measuring height and weight on final day.
Discussion Our investigating question was “how does ocean acidification affect Java Fern’s growth?” Our hypothesis was “If the water is more acidic, then the Java Fern will grow less”. As you can see in our graphs, in our experimental group the plant grew since the water was less acidic. The hypothesis was proven because the height of our plant in the control group decreased. We learned that ocean acidification causes decrease of photosynthesis due to loss of chlorophyll. Humans cause ocean acidification by air pollution and carbon dioxide released by humans affects the ocean. In a food chain my plant is the producer. If this human impact continues, then Java Fern will start to die off. This will affect consumers of Java Fern which are goldfish and other tiny fish because they will not have food to eat. My investigation is valuable for humans because humans are the ones causing ocean acidification and need to find ways to prevent it.
