Middle schoolers at UND chemistry camp power lights with lemons and potatoes<\/strong><\/p>\n

When life gives you lemons, forget the lemonade. Make a homemade battery instead.<\/p>\n

That was just one of many lessons learned as 20 middle schoolers \u2014 wearing bright-blue gloves and protective eyeglasses \u2014 gathered around a supersized lab table in the lower level of Abbott Hall.<\/p>\n

There, they meticulously poked zinc-coated nails and copper wire into about two dozen lemons and potatoes to learn how much energy a fruit-and-vegetable snake could generate. (The answer, in case you\u2019re wondering, is about 24 volts.<\/em>)<\/p>\n

A day earlier, the young scientists lit up a small string of lights in a similar experiment. They also watched in awe as a bottle of blue solution turned colorless, then blue again, after giving it a shake. They plated the inside of test tubes with silver mirror. And they made double-forked pickles glow yellow.<\/p>\n

It was all part of UND\u2019s annual four-day Exploring Chemistry Summer Camp, <\/strong><\/a>organized and led by Teaching Associate Professor and Associate Chair for Education Shaina Mattingly<\/strong><\/a>. She\u2019s been part of the camp since its start in 2017.<\/p>\n

\u201cI absolutely love seeing the kids get enthusiastic and curious about everyday observations or even very simple and safe activities they can do in their kitchens at home,\u201d Mattingly said. \u201cIt\u2019s such a thrill to see them connect the chemistry of what\u2019s going on in front of them to what they experience in the outside world.<\/p>\n

\u201cIt always inspires me and motivates me. It reminds me of why I love my job.\u201d<\/p>\n

\u201cThe students always are amazed to learn just how much chemistry is around them in their everyday lives,\u201d says Teaching Associate Professor and Associate Chair of Education Shaina Mattingly (above). Grand Forks sixth-grader Anthony Harris (below) carefully mixes a solution for an experiment, and Mattingly (far below) makes a batch of \u201celephant toothpaste.\u201d Photo by Owen Britton\/UND Today.<\/figcaption><\/figure>\n

Exploring everything from paper to polymers<\/h2>\n

Each day of the camp is designed to focus on a different chemistry-related theme: papermaking and pigments, batteries, chemical reactions and polymers. (Polymers? \u2026 Just think Shrinky Dinks and superstretchy slime.<\/em>)<\/p>\n

The summer camp is open to any student entering fifth through eighth grade.<\/p>\n

Middle school marks a very \u201cfoundational and key developmental\u201d age for children, Mattingly explained.<\/p>\n

\"Boy

\u201cAt that age, kids are starting to make connections on concepts that can be very complex,\u201d she said. \u201cThey\u2019re observing. They\u2019re thinking \u2014 always thinking \u2014 so it\u2019s really good to challenge them with chemistry experiments that are very visual, hands-on and designed to pique their interest.\u201d<\/p>\n

And what possibly could be more interesting than \u201celephant toothpaste?\u201d<\/p>\n

The answer is not much<\/em>, according to Grand Forks sixth-grader Anthony Harris.<\/em><\/p>\n

\u201cThe elephant toothpaste was my favorite thing,\u201d Anthony said. \u201cIt was so much fun. It kind of just foamed up and went over the sides. Our hands were dirty, and we got all crazy with it.\u201d<\/p>\n

The concoction \u2014 which gets its name because just a tiny squeeze would be fitting for a pack of pachyderms \u2014 is made with a plastic bottle and the proper mix of dry yeast, warm water, liquid dish soap and 3% hydrogen peroxide. Mattingly explains the basics of the chemical reaction this way:<\/p>\n

\"Shaina

The yeast acts as a catalyst that rapidly breaks down the hydrogen peroxide and turns it into oxygen and water.<\/p>\n

The oxygen gas forms bubbles that ordinarily would escape from the liquid and quickly pop, but the surface tension from the dish soap traps the bubbles to create a wild fountain of blue foam instead.<\/p>\n

It\u2019s a hit every year, Mattingly says \u2014 so much so, that she treats the students to a larger-scale demonstration of the experiment on the final day of camp.<\/p>\n

\u201cThey\u2019ve been waiting for that all week,\u201d she said with a laugh.<\/p>\n

(By the way, there are a lot of such fun and easy chemistry experiments for middle schoolers out there. We\u2019ll add some links below, including one with instructions for elephant toothpaste.<\/em>)<\/p>\n

Never a dull moment in the lab<\/h2>\n

Anyone who can imagine 20 middle schoolers tackling a thick binder of experiments in a full-scale college chemistry lab also will understand how there\u2019s never a dull moment.<\/p>\n

\"Girl

And that\u2019s why Mattingly says she appreciates the steady patience and assistance of several college students from the National Science Foundation\u2019s Research Experiences for Undergraduates program.<\/p>\n

Johan Dominguez, a physics student at Concordia College in Moorhead, was one of the REU students on hand to help at the camp. He shared that he first was turned on to science while only a fourth-grader at his STEM-based elementary school.<\/p>\n

\u201cIt\u2019s been really nice seeing these kids have that same experience of slowly connecting the dots,\u201d Dominguez said. \u201cThey\u2019re always asking great questions, and the ideas are constantly popping up. It\u2019s been amazing to see them using their critical thinking skills. To be honest, these kids are really smart.\u201d<\/p>\n

UND Chemistry<\/strong><\/a> graduate student Herbert Che Mughe echoed that sentiment.<\/p>\n

\u201cThis is my first year working with the camp, and my favorite part has been watching the students get so excited to learn new things,\u201d Che Mughe said. \u201cI think being able to do the experiments hands-on goes a long way toward opening their minds to the possibility of actually venturing into the field of science for a career one day.\u201d<\/p>\n

Planting the seeds for lifelong love of science<\/h2>\n

Mattingly dreams of that, too.<\/p>\n

\u201cI\u2019d love to see some of the camp kids end up majoring in Chemistry<\/strong><\/a> at UND. That would be my ultimate goal,\u201d she said.<\/p>\n

And with seventh-grader Sophie Dorward and sixth-grader Anna Sickler elbow-deep in homemade slime, that possibility was looking more and more likely.<\/p>\n

Self-described science fans since \u201ca very young age,\u201d the Grand Forks girls already have aspirations for careers in the field. Sophie says she might like to write science books, and Anna wants to use chemistry to create new medicines.<\/p>\n

\u201cAt first, I thought camp was going to be just sitting down and doing boring stuff, but it wasn\u2019t anything like that,\u201d Sophie said. \u201cIt was a ton more fun because we got to work with our hands. We weren\u2019t just watching and listening to other people explain it.\u201d<\/p>\n

Added Anna: \u201cYeah, I was amazed by how many cool experiments we packed into only four days. It made wearing the goggles and gloves all worth it.\u201d<\/p>\n
