Educators must therefore rethink the goals for Science instruction such that both students and those who teach Science must focus on the NOS itself- rather than its facts and principles (McComas, 1998). This study investigates the efficacy of using the STS approach in teaching rotational and circular motion in enhancing SINOS and SBPaLP. Senior high school students belonging to an intact class were the participants of the study. The study utilized the following instruments to gather data pertinent to the main problem: SINOS and CLASS questionnaires, structured interviews, reflection logs, and implementing teacher’s daily journal entries. Analyses of the data gathered involved the use of the SINOS constructs adapted from Chen, et.al (2013) and Attitudes towards Science constructs adapted from Adams, et.al (2004). The results reveal that student...

For an aquatic ecosystem to be able to support life, its DO level should be at least 5 to 7 parts per million (ppm). A lot of factors affect the DO levels of bodies of water, one of which is pollution, which is evident in the country. Two aquarium plants, namely: Cabomba aquatica and Echinodorus amazonicus were experimented using the modified Winkler Method to qualitatively determine which among the two plants release more oxygen through photosynthesis and would be more effective in the rehabilitation of bodies of water. After three trials of laboratory testing, the C. aquatica is found to be more efficient in increasing the DO level of water. Moreover, additional qualitative methods (e.g. colorimetric method) in detecting dissolved oxygen were recommended to give more opportunities in determining the presence of dissolved oxygen.
