Group 4 Project Journals

In order to determine that everyone has participated and contributed, each member of every group is required to submit an individual G4 Project Journal that will be sent to the IBO.  Please include Dates of discussions and Names of individuals and detail the “minutes” of your meetings.  Remember, in order to justify 10 hours of IA you must document at least 10 hours of work

Overarching Topic:   “Industrial/Commercial Process”

  1. PLANNING STAGE        

Explain all of the finalised details of your specific Planning

What is the process?

Our process was an industrial one called Aquaponics. Aquaponics is basically the combination of aquaculture (raising fish in a tank) and hydroponics (cultivating plants in water). It can be used in the farming industry as farmers use it to farm at a large scale (acres). Also people harvest a vast amount of edible fish from this closed ecosystem. With that in mind, we would grow fish and plants together in one integrated system and test the chemistry of the water in relation to different elements present in the system, such as: Ammonia, nitrites, and nitrates in a nitrogen cycle. Then we would investigate the biological impact on the entire system in regards to the fish waste inside and how it provides a food source for the plants and the plants provide a natural filter for the water in which the fish live. The submersible pump pumps the water throughout the system in which the physics lab would be conducted to investigate the behaviour of water.

Next, we started to build the system and bought the fish in a separate container. When we were done building the system, the fish were introduced. Then we integrated the plants into the system and did a Chemistry lab to test the chemistry of water.  After these tasks were done, we discussed poster ideas. The poster would involve our data collection and processing of our labs conducted and pictures of our system and its components.

  1. Definition of Activities

  1. How would each of the group 4 experimental science subjects help in this process?

Chemistry: Responsible in regards to our observation of the nitrogen cycle (levels of nitrite, nitrate, and ammonia) over the course of a 18-day period. Chemistry is also responsible for investigating the chemistry and behaviour of water in the tank system (chemical/physical properties and chemical/physical changes).

Physics: Responsible for conducting the lab for testing the mechanics of the siphon by comparing pipe diameter to flow rate of the siphon in order to determine the optimum diameter of the pump in ...
