If someone over the age of, say, 30 were to step into a classroom today, the first thing that will likely jump out is the lack of a blackboard. No, kids today write on whiteboards with dry erase markers, like any office professional in a conference room. No more clapping erasers together to whip up a cloud of dust. Chalk dust can trigger asthma and allergies, so the old school chalkboards have been phased out. Perhaps The Simpsons should update its opening credits sequence?

While not entirely gone, these metal sharpeneres are rarer and rarer these days, steadily replaced by electric and plastic devices. Who can forgot the noise of those metal gears chewing into the wood of a fresh pencil? Bonus points to you if you used all six sizes on the wheel. You needed that wide gauge for the Husky pencils.

There are many things about the dreaded rope climb to not miss, from the shame to the rope burns. However, if you could get to the top, you felt like the king of the world, or Tarzan at least. A stiff, two-inch-thick gym mat was not going to matter much if you fell from the rafters. Hence, the rope climb is no more.

Who could forget those red rubber orbs with the reptilian skin? Certainly not a kid who was konked in the head with one. The P.E. sport is on the endangered list, as it increasingly becomes banned due to its overall air of uncontrolled chaos. If the game is still played, foam balls are likely used.

Field Day was once akin to an adolescent Olympics, with traditional track and field events, podiums and placement ribbons. The victor scored the coveted blue ribbon, while those who came in second, third, fourth, etc., nabbed ranked ribbons made of red, white, green, purple, orange and so on. Today, kids runs around for a bit and then eat ice cream before everyone takes home the same "Participant" ribbon.

Educational films just aren't the same without the din of a projector. When the spinning reel came to an end, the tail of the film flapped and slapped against the metal. That was a wake-up alarm for some kids.

Domestic skills like cooking and personal finance are still taught in some schools, though the class is now called FACS — Family and Consumer Science. "Home Economics" has been phased out of the parlance. Which is odd, as its more about "home" and "economics" than "science," really.

There's an app for that.

To some MeTV viewers, "Melmac" might be best known as the home planet of ALF. Melmac is also the commercial name of melamine, the tough, Formica-like material used to mold old school lunch trays. It is also called "Texas Ware." With four rectangular compartments, a round depression and silverware slot, these things kept your milk, dessert, pizza, corn and tots in neat order.

Flimsy carbon paper was a hassle. It slipped around, crinkled in a gentle breeze, and shed charcoal powder everywhere. But it sure beat writing the same essay twice. People still use the term "carbon copy" without likely knowing the origin.

There are certain scents that will forever be associated with 20th-century schools. That awful pink vomit powder. The cedar and graphite of sharpened pencils. The fresh flesh of hands vigorously scrubbed with Boraxo.

Yeah, they had those handles on the side, but we always managed to run over a finger or two when shuffling around on our backsides.
