This paper reports an immersive virtual reality lab (iVRLab) training environment that offers college students an immersive and embodied experience in engineering lab work. The iVRLab provides a simple and safe environment for students to learn the complex lab operations to process and prepare silicon wafers. It features highly embodied interactions congruent to the actual body movements to manipulate the lab devices and materials in the physical world. Fourteen college students participate the lab training and the study results reveal positive learning effects, confidence levels of accomplishment, and embodied experiences. Students' cognitive load is also measured, and its relationship with the embodied experiences is examined and discussed. The study offers a reference for peer researchers and practitioners for the design and implementation of immersive VR systems for engineering lab training. It also sketches a complementary approach during the time like the pandemic to practicing authentic lab work without having to be in a real classroom or laboratory.
