Abstract
This research study dealt with the Hands-on Activities in Science for Grade 7 in Tanay West National High School during the School Year 2022 – 2023. Descriptive-developmental and experimental methods of research were used in the study. In order to determine the level of performance of the respondents, Spearman-rho and Pearson r, Mean and standard deviation, t-test, mean gain and percentage and Weighted Mean were the Statistical tools used. The findings of the study were as follows; The test items were found Highly Reliable and Valid. In Chemistry, the performance of experimental group was Developing (D) in all the lessons during pretest. On the other hand, the post test result was Proficient (P) in Acids and Base and Advance (A) in Metal and Nonmetal. While the control group performed Developing (D) in their pretest, the performance increased as Approaching Proficiency (AP) in all the subtopics under Metal and Nonmetal. In Biology, the performance of the experimental group in pretest was in Developing (D), while in the posttest, it became Proficient (P) and Advance (A). On the other hand, the performance of the control group was Developing (D) in their pretest and Approaching Proficiency (AP) in their posttest. There is a significant difference in the Level of Performance of both groups of respondents in their pretest and posttest results, thus, the null hypothesis was rejected. The Level of Performance of both groups as revealed by the Posttest results with respect to Chemistry and Biology, significantly differ. The developed Enhancement Activities in Chemistry and Biology with respect to the different criteria were found effective and Very Much Accepted as instructional materials.
