Abstract

Small-scale chemistry experiments is a teaching approach often utilized in schools and institutions. It is carried out by means of little glassware for laboratories and drastically cuts back on the quantity of chemicals. It can also assist in overcoming increasing worries over issues with pollution in the environment and growing laboratory expenses. The purpose of this quasi-experimental study is to investigate the impact of small-scale experiments on students' engagement and retention of concepts in teaching chemistry lessons. A pretest and posttest were given to the purposely-selected grade 7 student participants prior and after the conduct of the lesson with the integration of small-scale experiment, respectively. The results were then compared and analyzed using the SPSS tool to get the mean, standard deviation, and the t-test of paired samples. The results revealed that when students in Grade 7 were taught Chemistry using microscale laboratory techniques, their test scores had increased both before and after. On average, learners’ understanding and concept retention improved when introduced to hands-on experiences using microscale experiments
