Abstract

This study tries to determine the concentration of sea surface microlayer from different coastal environments (Port Dickson, Negeri Sembilan and Perhentian Island, Terengganu). The concentration of surfactants in both sea surface microlayer and atmospheric aerosols were analysed by using colorimetric method as methylene blue active substances (MBAS) and diethyl violet active substances (DBAS). The results indicated that the concentration of surfactants as MBAS (0.421 +/- 0.040 imol l-1) and DBAS (0.294 +/- 0. 123 imol l-1) were still at the natural concentration level. The flux of surfactants from sea surface microlayer is expected around 2.3 Mmol yr-1 compared to the amount of 1300 Mmol yr-1 surfactants in atmospheric aerosols around marine ecosystem.

Abstract

In contemporary education, fostering curiosity in science learning is essential for enhancing students academic performance, particulary in junior high school. This study aims to explore the relationship between students curiosity in science learning and their learning outcomes in junior high school, focusing on three dimensions of curiosity: Stretching, Science, and Embrace. A correlational quantitative approach was employed, involving 147 students, with data collected through questionnaires, learning outcome assessments, and interviews. The results indicated that curiosity plays a role in improving learning outcomes, as evidenced by the average scores increasing from grade 7 (82.2) to grade 9 (85.8), influenced by the interactive teaching approach. However, despite an average curiosity score of 66.52, the correlation between the dimensions of curiosity and learning outcomes was found to be very weak (p 0.05), highlighting the need for more innovative learning strategies to effectively harness curiosity in the classroom
