As in many computer games, the goal of “Cellvival” is to survive in a hostile environment. Unlike most others, though, this game teaches some basic science. And unlike a lot of educational games, it’s fun to play.

You play as Tetrahymena thermophila, a single-celled organism that lives in fresh water, trying to catch food and avoid being eaten, and ultimately to reproduce and survive as a species. When you get enough food, you can reproduce, and when you reproduce you can adapt. The trick is to choose traits that will make you better equipped to survive. There are trade-offs: Speed makes your organism less maneuverable, and vice versa. Instead of levels, the game puts you in different environments, and the traits that make you best fitted to survive will be different in each one.

Ithaca-area high school students have been playing – and enjoying – the game, and whether they realize it or not, learning how evolution works, how the characteristics an organism inherits interact with its environment. “In order to play a game, you have to learn how to play the game, so kids are used to getting information from games,” explained Andrew Jefferson, a graduate student in the field of human development, who spearheaded development of the game. “One reason we went with evolution is that it involves abstract things that are hard to visualize. In a game you can take something abstract and make it concrete and play with it and experiment. Even if they die [lose the game], that’s still teaching them something about how it works.”

The project grew out of Jefferson’s conversations with Walker White, director of the Game Design Initiative at Cornell (GDIAC). Coincidentally, White had just been approached by members of the College of Veterinary Medicine’s ASSET (Advancing Secondary Science Education with Tetrahymena) program, who were interested in creating educational games to go with laboratory modules they provide to biology teachers. Jefferson works with Steven Ceci, the Helen L. Carr Professor of Human Development, and human development professor Wendy Williams, and has recruited a team of computer science students as programmers. He will describe the project at the Games, Learning and Society conference in Madison, Wisconsin, June 11-14. You can try out the game yourself at the GDIAC showcase, May 16 in Carpenter Hall.

After some polishing, the game will be distributed free to teachers through the ASSET program, along with lab modules that let students work in the classroom with the real Tetrahymena organism. Several teachers around New York state have already expressed interest, Jefferson said. The game is available in PC and Mac versions, with an accompanying lesson plan to guide classroom discussion.

The challenge, Jefferson said, is to satisfy both kids and teachers. “Educational games get a bad rap,” he noted. “Kids compare it with the games they paid for. Often in educational games you’re just answering quiz questions. … But if you don’t have those questions, teachers ask if kids are learning the game but not learning the content. It’s a balancing act.” But so far, he said, reception has been favorable. When he demos the game to adults the response is often, “That looks a lot better than I was expecting from an educational game.”

Testing will soon move to Ithaca middle schools, and Jefferson plans to create more games, in particular one that teaches critical thinking skills. The work so far has been funded by the National Institutes of Health.

Beyond the buds and the daffodils, another spring rite emerges: undergraduate research presentations.About 140 students presenting 115 individual pieces of research gathered for the 29th annual Cornell Undergraduate Research Forum April 16 at Duffield Hall, while 45 seniors convened for the Hunter R. Rawlings III Cornell Presidential Research Scholars Senior Expo 2014, April 17 at the Biotechnology Building.

Ranging from cancer research and possible pharmaceuticals for diabetics to cooking a better steak, almost 200 undergraduates conveyed their academic prowess.

Michelle Duong ’14 showed that an environment influences food intake. In two focus groups – each before a bowl of chocolates – the people who discussed gym memberships ate fewer sweets than those who discussed a nonhealth topic.In her research, Shanique Alabi ’14 learned that Canada goldenrod (Solidago canadensis), which she found at the Cornell Plantations, may offer promise as a carbohydrate digestion blocker for diabetics.

Jessica Lebovits ’14, Nolan Reese ’15, Janet Kim ’15 and Olivia Roche ’15 studied the culinary learning process of off-campus college students to ascertain nutrition among young adults. Louis Levine ’16, Rachel DeMel ’14, Camille Kapaun ’14 and Paige Mintz ’15 learned how off-campus students manage their time in preparing meals with the aim of improving their meal choices.

Conor Gruber ’15 studied the early detection of circulating tumor cells in pancreatic cancer, working toward an assay that ascertains cellular nuances; and Karen Martin ’15 examined the process of RAC1 proteins as it relates to metastatic cancer.

While Marissa Tranquilli ’15, Simeon Markind ’14, Katherine Bruce ’14 and Benjamin Catanese ’14 characterized the carbohydrate content of the Ithaca Beer Company’s Apricot Wheat and Green Trail beers with high performance liquid chromatography-refractive index detection, other student chemists Janette Guijosa ’14, Sarah Goodnow ’14, Daniel C. Lee ’14, Harrison Specht ’14 and Ashley-Lauren Mighty ’14 provided an aroma profile of Ithaca Beer’s Flower Power IPA in various stages of production.

Rachel Lumish ’14 correlated pica behavior (consuming non-food items like chalk, ice, powder, soap and dirt) and its relationship with iron deficiency among pregnant teens. And Quinn Kelly ’14 analyzed bicycling policies in major American cities, with an eye toward improving sustainable transportation. He found that cities with the strongest bicycling organizations had the strongest cycling infrastructure and policies, and the largest amount of cyclists.

James Zen Yui ’14 showed how to save energy and grill a better steak by pre-cooking the meat in a vacuum-sealed plastic and storing it in water, which keeps the meat tender. When ordered in a restaurant, the juicy so-called sous vide steak is grilled for a few minutes.

To create equity in discrimination lawsuits (based on Title VII of the Civil Rights Act of 1964), Hannah Clark ’14 assembled a database of factors that correlate with larger settlements and relief clauses in settlement documents.

Spenser Reed  ’14 evaluated chicken as a potential model for an inexpensive and sensitive zinc biomarker to quickly assess human nutritional needs, while Joseph Edwards ’14 explained how he used electrospinning and electrospraying to create membranes that use biochar to trap volatile organic compounds, for possible use as a smokestack filter.

Department of Human Development well-represented!

Of the students involved in the presentations, 21 were Human Development majors or worked with a professor from the department: Victoria Atzl ’14, Martina Azar ’14, Olivia Butkowski ’16, Morgan Drucker ’14, Lara Gentilini ’14, Jeanie Gribben ’15, Amauri Gomez ’14, Azraa Janmohamed ’16, Corey Keane ’15, Kyle Kurkela ’14, Wei-Feng Lee ’16, Samantha Marfurt ’14, Meghan McDarby ’14, Nicole Meyers ’14, Hye Eon Park ’15, Carly Schuller ’16,  Leah Shabo ’16, Victoria Silverman ’15, Colleen Sullivan ’16, Masrai Williams ’15, Lilly Zhang ’14.
