For effective science enquiry and acquisition of concepts in science learning, learners should have a good mastery of the science process skills (SPS). SPS are the fundamental components of problem-solving, critical thinking and enquiry in science. The main objective of this study was to establish the effectiveness of YouTube videos in developing SPS in the Grade 10 Life Sciences curriculum. The study was framed by a model of evaluating the effectiveness of YouTube videos. It was supported by the theories of constructivism and active learning. The pre-test and post-test and a semi-structured questionnaire were administered to 100 conveniently selected Grade 10 Life Sciences learners of a secondary school in KwaZulu Natal. Quantitative data were analysed using descriptive statistics, which comprised a t-test. Qualitative data were analysed using a thematic analysis method. The null hypothesis was that there was no statistically significant difference between the performance of learners in the pretest and post-test. The results of the study revealed that there was a statistically significant difference in the learner’s post-test performance. The YouTube videos had a significant impact on the development of skills such as inferring, interpreting data, constructing a hypothesis, communicating and predicting, as these showed an average increase of 40,2%. The learners demonstrated a positive perception of YouTube videos, as they improved their development of SPS. Hence, it was recommended that teachers incorporate relevant YouTube videos and design effective practical tasks to enhance and elevate
