I Taught Anaerobic Fermentation To Little Kids For A Day But Here's What *I* Learned

I really just aimed to teach a few children a little about yeast releasing carbon dioxide, but by the end of the hour, I’d learned a bit myself.

I Taught Anaerobic Fermentation To Little Kids For A Day But Here's What *I* Learned
Wamia Siddiqui

This past Saturday was Rutgers Day, and for anyone who doesn’t know, this is an annual event where New Jersey residents flock to their closest Rutgers campus for performances, food, arts and crafts, a petting zoo, giveaways and more free scarlet paraphernalia than one could ever fathom what to do with. Scattered across three campuses with a table for almost every department and organization, the endless meandering provided me much-needed distraction from studying right before AP exam season come May.

In past years, I would happily wander around, enjoying funnel cake and collecting R-shaped magnets with my friends and family, inevitably getting lost and resorting to asking one of the Rutgers students volunteering at the tables — in their iconic purple Rutgers Day shirts — to point out where to go.

This weekend, I was the one wearing a purple shirt, and have to admit, Rutgers Day is a completely different experience standing on the other side of the table.

The sheer amount of coordination and logistical planning that it takes to organize an event of this monstrosity is beyond belief, but the activities each organization plans for their table’s activities and offerings independently. When I signed up to volunteer at the STEM Ambassadors table, little did I know that this involved blowing up balloons with yeast and sugar, to demonstrate how anaerobic respiration works. Having taken more biology classes than I can count on one hand, this wouldn’t have been a problem, if my audience wasn’t comprised primarily of children still in elementary school.

Even worse, when I woke up in the morning and checked the sign-up sheet, I realized that for about an hour that day, I would be manning the table, alone, tasked with the responsibility of inspiring kids to like science and pay attention to yeast, while within eyeshot of a petting zoo and more cute puppies than one could know what to do with. Honestly quite daunted by the prospect of kids being apathetic to science, or even worse, scared off by the jargon, I arrived at the table uncharacteristically nervous. Public speaking is one thing, but teaching advanced concepts to children, the toughest possible crowd, and trying to foster in them a love of science, is completely another.

As I approached the table, I was surprised to see a crowd of little kids, some barely able to see over the edge, all peering at a sole person, the current President of STEM Ambassadors, towering over them. I stood awkwardly on the side, watching her pour a little bit of dried yeast into each child’s hands, and enthusiastically explain why only one of the balloons on the table had inflated. Her zeal was almost calming, and soon, when it was my turn after her shift ended, I tried to channel that same energy.

I put on a fake smile and started trying to explain, eventually perfecting a strategy and feeling my smile become more and more genuine. I started off with each kid by asking what grade they were in and if they liked bread. Then, I’d pour some of the dry yeast into their hands, point excitedly, and explain that they were living organisms and, more importantly, the reason why bread is tasty. I even made jokes about yeast being “fun guys” (fungi), which the younger kids appreciated but the older ones not as much. After explaining that yeast needs sugar the way we need food and that they breathe out carbon dioxide just like us, and throwing in concepts like aerobic vs. anaerobic respiration. Pointing out why only the balloon stretched over a bottle containing yeast, sugar, and water, and not the other combinations, was mildly interesting, but I could see that the kids wanted to actually do it themselves, not just watch balloons.

After hunting down the free water bottle cart and “borrowing” quite a few of them, I was equipped to let the kids try it out themselves, handing them their own bottle full of yeast and sugar, with the promise that yes, eventually, it would indeed inflate. I can only hope they believed me, and if anything, enjoyed being able to run their own “experiment” by themselves. Over the course of the hour, I met a vast variety of children, some in fifth grade and well-aware of what yeast do, some barely even able to speak.

Going into this experience, I really just aimed to teach a few children a little about yeast releasing carbon dioxide, but by the end of the hour, I’d learned a bit myself. When I asked each of them what their favorite classes were, I was surprised by the overwhelmingly positive responses about math and science, a refreshing sign for the future of STEM. This was especially inspiring, when mothers who were alumni of DRC and former STEM Ambassadors brought their own children, initially steering them towards the table and taking pamphlets on other at-home science experiments they could perform. I met a lot of little girls who already loved science, and could only hope this persisted through the years. I also met a few girls who heard “science experiment” and immediately scowled, and for them, I could only hope that one day they’d change their minds.

Perhaps, years from now I’ll bring my own children to the STEM Ambassadors table on Rutgers Day, pry them away from the cute puppies and tell them to go learn just a little bit about yeast. Maybe, just maybe, the person on the other side of the table, can learn something too.

Course registration at college can be a big hassle and is almost never talked about. Classes you want to take fill up before you get a chance to register. You might change your mind about a class you want to take and must struggle to find another class to fit in the same time period. You also have to make sure no classes clash by time. Like I said, it's a big hassle.

This semester, I was waitlisted for two classes. Most people in this situation, especially first years, freak out because they don't know what to do. Here is what you should do when this happens.

Challah vs. Easter Bread: A Delicious Dilemma

Is there really such a difference in Challah bread or Easter Bread?

Ever since I could remember, it was a treat to receive Easter Bread made by my grandmother. We would only have it once a year and the wait was excruciating. Now that my grandmother has gotten older, she has stopped baking a lot of her recipes that require a lot of hand usage--her traditional Italian baking means no machines. So for the past few years, I have missed enjoying my Easter Bread.

Top 10 Reasons My School Rocks!

Why I Chose a Small School Over a Big University.

I was asked so many times why I wanted to go to a small school when a big university is so much better. Don't get me wrong, I'm sure a big university is great but I absolutely love going to a small school. I know that I miss out on big sporting events and having people actually know where it is. I can't even count how many times I've been asked where it is and I know they won't know so I just say "somewhere in the middle of Wisconsin." But, I get to know most people at my school and I know my professors very well. Not to mention, being able to walk to the other side of campus in 5 minutes at a casual walking pace. I am so happy I made the decision to go to school where I did. I love my school and these are just a few reasons why.
