Eighteen experiments in introductory physics are developed for a one-semester course. The experimental topics include the kinematics, the Newton’s laws of motion, the collisions, the sound and waves, the reflection, refraction, and diffraction of light. The experimental materials come from life materials. The measuring equipment is composed of length and weight meters and built-in measuring functions of smart cellar phones of standard version. Instructional materials for all experiments are constructed based on the science development strategy of the exploration, the observation, the model-building, and the prediction. Each experiment has been tested by the author in his teaching classes for college students of different science backgrounds. A questionnaire survey for the students involved in the teaching classes has been performed. The survey indicates that the students become more interesting and active in the hand-on experiments than they are in the traditional experiments.
