I find it difficult sometimes to explain my job to adults, and kids are a whole other level of complexity. What we do is difficult to boil down and not make it sound more boring that we think it is.
This posts reminds me of a conversation I had after college graduation with my preschool class at church.
"Guys, this is Ms. Heidi's last week as your teacher." - me
"yeah, she has to go to Tulsa to be a big engineer" - 5 year old's interpretation of what his parents told him
* slight pause before the same kid spoke again *
"oh! on a train!" - same 5 year old
"Well, not on a train. That's a different kind of engineer."
(The disappointment on all their faces was very clear at this point.)
A few said they would miss me.
"Well, you can tell your parents that if you guys visit Tulsa, they can let me know and maybe you can come visit." -me
"Will we get to see a train?!" - another 5 year old boy
"Maybe, but only because my apartment is by the train tracks... I don't work there."
Later, they wanted to know what I do if I don't work with trains. I tried to explain that when someone builds a building, I help design things we need like water lines and sidewalks, and I try to make it so that it doesn't flood. They they asked if I could build a new Hastings (the one in town had closed recently), and I said I don't get to pick what kind of building is designed. Once again, they were disappointed.
I was mentioning this to an older mechanical engineer afterward, and he said "oh, all the kids think I drive trains. I don't correct them anymore because they think trains are cooler than if I tried to explain what I do."
The last time I spoke with high school students, I tried to summarize Civil Engineering in the introduction by listing ways that they are all impacted by the designs of Civil Engineers on a daily basis -- clean drinking water, sewage removal and treatment, roadways and bridges, accessible sidewalks, safe building structures, and flood reduction and prevention. Then I went into "a day in the life of a site development civil engineer" and described how my job can be broken down into understanding needs, solving problems, and ensuring quality. I then broke each one down into 2 or 3subitems.
