Four research questions and two hypotheses were formulated in conformity with the stated objectives. The reliability of the twenty test items were obtained through pilot study,  using Pearson Product Moment Correlation Co-efficient r=0.78. While Cronbach Alpha was used to test the reliability of the questionnaire r=0.55. The two null hypotheses were analyzed using Ttest with α = 0.05. The researcher recommended among others that, chemistry teachers should see laboratory exercises as a need that cannot be avoided.
