Data collected sequentially were analyzed using the Content Validity Index (CVI), Descriptive Statistics, and Independent Sample t Test. The results obtained were Predict-Observe-Explain student worksheets: 1) content valid criteria with a CVI value of 0.9, 2) good practicality criteria with a percentage of 79.56%, and 3) effective criteria in increasing understanding of the concept of Natural Sciences with evidence of a significant difference between an increase in the average understanding of the concept of experimental class science by 21.3750 higher than the increase in understanding of the concept of science in the control class of only 16.2500. Abstrak: Penelitian ini bertujuan untuk menghasilkan lembar kerja siswa berbasis Predict-Observe-Explain pada pelajaran IPA kelas IV tema Selalu Berhemat Energi yang valid isi, praktis penggunaan, dan efektif dalam meningkatkan pemahaman konsepnya.
