This study investigated the effect of laboratory method and video-based instruction on performance in practical Chemistry among senior secondary school students in Bauchi state. A total of 126 students were sampled from co-educational senior secondary schools within the three educational zones of Bauchi State using purposive sampling technique. The study used the pre-test, post-test quasi-experimental control group design. The instrument used for data collection tagged “Chemistry Practical Test” (CPT) was validated by experts in Science Education, Chemistry and a qualified and experienced secondary school Chemistry teacher. The instrument is also considered reliable with a Pearson product moment correlation coefficient of 0.82 using test-retest method of testing reliability, using data from trail test. Two research questions raised during the study were answered using mean and mean differences and two null hypotheses were tested using Analysis of Covariance (ANCOVA) at P ≤ 0.05. The major finding from this study include: Students taught practical Chemistry using laboratory method had better achievement than the other groups. It was then recommended that teachers should be encouraged to teach practical Chemistry using laboratory method.
