The CBIA (Connecticut Business and Industry Association) has a great site with education resources. One part of it is called "Career Pathways." In this section, there are videos and teacher's guides for helping students learn about different careers. I've used them and the resources are excellent. For the engineering career one, they have interviews with engineers and follow them on their daily work. The teacher guides have lesson ideas and student resources that make these very easy to use.
I recommend them to career teachers and counselors as well as class room teachers. You can use these to connect what you are teaching to real world careers.
The career areas are: Energy and Green Technology, Engineering, Health and Biosciences, and Manufacturing. Even though it is geared towards Connecticut, anyone can use these resources.
