Bedtime with K-boy

K-Boy needs stories to go to bed, so his dad obliges. In Season 1, stories include T-Rexes or diggers or animals, or a combination. K-Boy does have some comments to make at times. In Season 2, stories become more adventurous with space battles to defend Earth. With an engineer as the narrator, kids get insight into how an engineer thinks and how science, technology, engineering, and math fits into the drama and strategy. Can you find the STEM?
