If you are trying to teach your students about Engineering and Technology or STEM, it would be a great idea to help them understand the various types of jobs in engineering. There are way more than 26 of them, but this set of cards is an introduction to the many careers in engineering. You can review these jobs, and then get the kids to come up and play vocabulary charades to see if they were paying attention.
