How Do I Talk To 4th Graders About IT?
Tsunayoshi writes "My son volunteered me to give a presentation on what I do for a living for career day at his elementary school. I need to come up with a roughly 20-minute presentation to be given to 4-5 different classrooms. I am a systems administrator, primarily Unix/Linux and enterprise NAS/SAN storage, working for an aerospace company. I was thinking something along the lines of explaining how some everyday things they experience (websites, telephone systems, etc.) all depend on servers, and those servers are maintained by systems administrators. I was also going to talk about what I do specifically, which is maintain the computer systems that allow the really smart rocket scientists to get things into space. Am I on the right track? Can anyone suggest some good (and cheap/easy to make) visual aids?"

BINGO!
There's a lot of angles you could approach your job from but if I can give you any advice, keep it entertaining. I volunteer to teach grade school kids occasionally and what we do is an engineering challenge for each class. We do many different challenges but an example is handing out limited supplies to each team and having them build paper planes. Sometimes we throw in random stuff like paper clips or rubber bands to see what the kids try to do with them. While they work, we talk about engineering in general. At the beginning we'll give them specific requirements in a childish Statement of Work style which lay out how we are selecting the best airplane or bridge or tower or whatever.
At the end of the session we start to ramp up the specifics as we do the final tests on the stuff they made and hand out candy. I'll start to talk about structural integrity, how we use math to make things better, etc. As I get more technical, I'll start to lose kids but there are usually a few that get excited and that's why I'm there.
If you go there set on talking about just IT, you're going to lose them and--worse--possibly turn them off to technical jobs like that. Stick to the end product of what you actually provide. Try to think of fun facts to keep them entertained--don't say petabyte, figure out how many times around the world one string of text will go that a petabyte can store. Then tell them how many of those you are in charge of. I also suggest you start out generic--ask the kids what an engineer does and then get more specific with your job and place.
Also, my company always has junk left over from bring your child to work day, hand that stuff out like prizes or give one to each student if you have enough.
My work here is dung.
Flowcharts, and keep it simple. Visual aids really help.
"Talk to your kids about IT ... before someone else does."
Explain that software is like a city... pipes, houses, roads, bridges. Explain that there are people who design the stuff, make it, repair it, and use it. Explain that this is the world they will live in, and give examples they can relate to: the phone network, the Internet.
Give them the understanding that IT is about stacks, layers, stuff that is old and deep, stuff that is fresh and useless...
Don't use technical words, don't try to teach anything specific at all, and don't try to sell Linux or open source (kids tend to respond to sales pitches cynically and negatively).
My advice above all is to explain how it's about people, doing things, making things, working together.

Start with the basics and work your way up from there.
I'd suggest axiomatic set theory first coupled with computing history, linear algebra and analysis. Throw in some logic into the mix for good measure. Once they got the basics point them towards the linux kernel and start discussing the more interesting issues of SMP, scheduling, latency and memory management.

Be yourself no matter what they say
One cheap visual aid would be an old computer and or server, so you can show them what it looks like inside a computer. My kids tend to like watching me swapping components, at least.

"See the Internet is a series of tubes! And you have to understand that those tubes can get clogged up!"
As one of the 21st centuries greatest thinkers said:
"And again, the Internet is not something that you just dump something on. It's not a big truck. It's a series of tubes. And if you don't understand, those tubes can be filled and if they are filled, when you put your message in, it gets in line and it's going to be delayed by anyone that puts into that tube enormous amounts of material, enormous amounts of material" - Ted Stevens
Get a dead hard disk drive, take the cover off so the platters and read/write head are visible. Pass it around the class while you talk. Computers and IT will become immediately more real to them once they can touch it and see that a computer isn't just a fancy TV with keyboard and mouse.
If you want to add an analogy they can relate to, also bring a long a stack of encylopedias or an OED and do the "the words in X many of these books will fit on that disk" comparison.
If your manager can understand it, a 4th grader should have no problem understanding what you do!
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
You're an aerospace sysadmin. So you're a roadie for rocket scientists.
Rocket Science = EXCITING!
So talk about how what you do holds up the exciting stuff.

As much as I hate to say it, MS actually got one right. They ran a webcomic (Heroes Happen Here) for a while, most of it wasn't too great. The 1st page is a kid asking his dad what he does for a living so he can give a school presentation about it. The dad goes on about what he does as a developer and it goes way over the kids head. So the kid tells everyone his dad drives an ice cream truck.

... let me know how, so I can explain it to my parents.

First step is to let your child know, in no uncertain terms, that volunteering you for anything in the future will result in two months grounding.

is to make your kids friends think your son has a cool dad.
System admin work is BOOooring to 4th graders.
Keep it a little more general, keep 'data' reasonably abstract.
Talking about computers to 4th graders is now like talking to 4th graders about the phone system. We all have phones, we all know how to use them, we all have the nifty features. It just works. Hard to make the interesting.
Give some examples of things going wrong and how you saved the day. Explain how rockets wouldn't be able to go without you. Kids love rockets.
Explain how rockets would explode without you. Make yourself a hero and make is sound like you are 'da man'.
I have a 3rd and a 5th grader, and I expect my time to give a presentation to the class is coming. As a programmer I am going to need to keep it lively. I will probably do some quick Lego robotic programming so they can see the reward for my work immediatly. I'll give the class a couple of decisions on what I will do.
Good luck.

1 digital camera, and connecting USB cables.
What you want to do, is involve the kids in the building of a quick web site, while talking about the technologies that make it all work. The network connectivity, the HTML that places THEIR pictures on the page, even talk about the various cables necessary to connect the computers, the camera to the computer, and explain what happens when they press ENTER. Literally trace the content down the wire.
Prepare a template ahead of time, take pictures of the kids, use some cool filters in Photoshop, and then add them to the web page. In the end, the kids get jazzed over seeing their picture on a web page, and will enjoy your explaining how it worked, from the camera to the page.
Dont be a dufus and go on about the wonders of DHCP, and all that. Its got to be applicable to what they care about.
Anyway, that worked for me, and I got a dozen calls from parents asking me for follow-on advice, as their kids demanded tools to build their own sites.
If you remember the principle of demonstrating how IT effects their lives, you will have a captive audience. I guarantee that if you get into IT from a nuts and bolts perspective, rather than applying IT to what kids care about, you will get snores.
There's a lot of angles you could approach your job from but if I can give you any advice, keep it entertaining.
I'd suggest a brief talk on satellites and then show them Google Earth. I give a presentation for my daughters 1st grade class on the solar system and ended on Google Earth. One flight to the Grand Canyon overlook and they were all clamouring to see various things (mainly local stuff like the school, where the teacher live, where they lived etc.) but I'm sure 4th graders would be far more imaginative.
Tell them that they're no longer needed, and give your lecture to some kids in a less-expensive country.
For added realism, have them train their replacements.

System administrator, eh? You can start by showing your scars.
All of my scars are on the inside :-(
Your child has condemned himself to the humiliation of having everyone know his father is a big nerd. Well, it's his own fault for volunteering you. Unfortunately, his respect for you will now plummet and you will have trouble keeping him off drugs three years from now. After several minor run-ins with the law, he will end up studying general accounting at community college, and take a job cooking the books for a corrupt tire warehouse in Des Moines. His wife will commit suicide at 32. Your grandchildren will be spoiled and ugly.
You can, however, prevent all this by claiming to be an astronaut.
I piss off bigots.
Start with a basic discussion of SysV vs. BSD, then move on to shells and explain why the Bourne shell his historically prefered to csh for scripts.
You might demonstrate a little sed and awk, but keep in mind that these are just kids, so you might just jump ahead to perl. Maybe wrap it up by talking about NFS and how network filesystems have changed since Samba came along.
Oh, and if you feel like you're losing them along the way, you can probably win them back with an Itanic joke :-)
Dear Slashdot:
I am trying to talk with my PHB^H^H^H^H fourth grader about IT.
Can you help?
