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.

"It's all about cookies. Who wants a cookie??"
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.
It takes a man to suffer ignorance and smile
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!"
System administrator, eh? You can start by showing your scars.
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

There are no loopholes. It's either legal or it's not.
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.
I always get jealous of IT folks when I see that they get to work with racks of equipment. It seems to me like it is building with Lego blocks for a living.
In addition to software installation and security, our IT folks plan out the hardware with the power and cooling requirements. I would have been fascinated by this stuff as a kid (and I still am).
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.

You don't do video games? Doesn't matter.
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.

Don't underestimate kids. They may be immature and annoying but they aren't stupid (naive and ignorant maybe but not stupid). Give them the tools and they will learn. I had my first computers (commodore 64 and a vic 20) at around 6 years old. I learned dos by 10 and had fixed dozens of electronic, computer, and mechanical devices around the house with no help from anyone (not even books). I'd be willing to bet that this anecdotal evidence is a mere drop in the pond compared to others on slashdot. I consider myself intelligent but I've seen tons of kids that blow me out of the water. The trick is just to find the right spark to get their curiosity going. (and each kid differs a lot in that realm)
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.
--I'm not talking about dance lessons. I'm talking about putting a brick through the other guy's windshield.-
You're a Unix sysadmin who reads Slashdot.
You don't expect us to believe that you have enough social skills to get to the point of having had children do you?

Translation: "I am a garbageman. I spend most of my time with a lot of expensive and neat looking hardware cleaning up the messes of people who think they are better than me. You know the neighbor across the street who tosses a bunch of leaky, smelly trash bags on the ground every week and doesn't bother using a can? That's Bob, the engineer over in building 4 who manages to run processes that ABEND every single time because he's an idiot, but he blames the network anyway. The guy down the street who always piles up dead branches and lawn clippings until it stops anyone from walking on the sidewalk? Meet Sue in building 3, who seems to find a way to generate 900GB of crap data that then crashes the network file share. Or perhaps the family down the street with the can so smelly nobody will get near it? That's Ralph, who corrupts his files on the network store at least once a month and needs a total restore from tape.
The only really big difference is that a garbageman has more job security and is probably paid better. Stick with that or plumbing- you'll go far since people will pay anything not to have to deal with it."
"Seven Deadly Sins? I thought it was a to-do list!"

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.

Presenting to fourth graders is like presenting to upper mgt, except they have less authority.
Use lots of flashy colors, slides with sounds and visual effects, and you can make anything look important if you have spongebob squarepants say it in your slide.

A rough road leads to the stars
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.
If you want to keep it exciting and still realistic, just present a slide show of dilbert comics.
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.
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.
Bring stuff you can pass around. As much stuff as possible. Short network cables. A small hub. Some system upgrade CDs (ones that are old enough that you don't mind fingerprints on them. A ring binder. Snapshots of server rooms, wiring closets, etc. A punchdown block and a punchdown tools. You know, stuff.
"How to Do Nothing," kids activities, back in print!
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?

You'll need to do a few things to give the kids a proper flavor for the job.
First, for no good reason whatsoever, insist that the meeting be held at 3AM, give no warning of this - just page them all at night.
Second, ensure the classroom is a cold as possible.
Third, in the background play some extremely loud fan noise.
Begin the session with recriminations, belittle the children for their lack of psychic abilities.
Repeat the same information to the children over and over a few times to see if the same phrase magically has a different effect. Berate the children for not doing what you think they should be doing.
End with demands that this never happen again.
Nullius in verba
(1) When you talk about *what* a systems administrator does, it doesn't sound that hard: installing and configuring software, patching, installing and configuring hardware, researching and comparing potential upgrade options, troubleshooting problems, etc.
What 4th graders probably don't think about is that none of these things by themselves may seem particularly hard at the scale of an individual computer, but when you multiply each of these activities by a gazillion servers, routers, clients, etc., then it has the potential to become a real nightmare. So you have to use tricks & technologies in a company's computing environment that you'd never bother with at home.
E.g., "Ever seen your mom or dad install a Windows update? Remember how nuts that made them? Now imagine doing that across 20,000 desktops in 10 cities, and being given only 3 days to get them all done!"
(2) Probably a lot of your time is spent being a detective, trying to puzzle out why something that oughta be working ain't. Telling stories about some of your successful detective adventures might be entertaining.
All people (including kids) like to be told stories, so the more you can populate your presentation with interesting anecdotes, the better.
And, as one person already wrote, bringing some old or broken hard drive, circuit boards, etc. to pass around the classroom probably couldn't hurt either.
Also, many 4th graders I know think that the *monitor* is the computer. They point at it and say, "That's the computer, isn't it? Why are you fiddling with that other box?" I know that sounds crazy, but that's the way many 9 year olds think. So don't assume any understanding of computers just because they know how to play Spore.
I hope that after I die the one word people use to describe me is "resurrected."
i'm kind of surprised at the funny mod too, i wasn't trying to be funny
that's really the best way for a bunch of grade school kids to appreciate an IT job at an aerospace company
