This study aimed to develop alternative laboratory experiments (ALEs) in Chemistry 8 and evaluate the perceived improvement of the students' basic science process skills after utilizing the material. This employed a mixed method of research. Initially, a self-assessment survey questionnaire was used to determine the basic science process skills of the 20 Grade 8 student-respondents. From the results, alternative laboratory experiments were developed and validated. Validated ALEs were given to the same group of respondents. At the same time, acceptability questionnaire was administered to the 21 teacher-respondents comprising the total population of science 8 teachers in the Division of Lucena City. The teachers highly accepted that the ALEs promote holistic development in all the three (3) learning domains, cognitive, psychomotor, and affective. To evaluate the improvement of the students' basic SPS, an individual in-depth interview was conducted. Qualitative analysis of the students' basic SPS revealed that the learners who utilized the ALE improved their skills. As perceived by students, they became mindful of the process of observation, execute alternative way of quantifying data and materials, identify the cause and effect, and use related observations, look closely at the properties and characteristics, made the good prediction based on recorded data, and improve in presenting data and explaining results. Therefore, the developed material in selected contents for Chemistry 8 that can improve the target learners' basic science process skills is ready for utilization in the home school scheme.
