Nineteen students from Conway and Little Rock middle and high school students attended 2018 Summer STEM Academic at UCA from June 25 through June 29, 2018. The academy was organized by the Department of Mathematics and the UCA STEM Institute. Students participated in three inter-connected activities in biology, statistics and computer coding. The activities started at 9:15 AM and concluded at 3 PM every day with 1-hour lunch break.

The Data Analysis & Visualization activity, taught by Dr. Mark Doderer from the Computer Science Department, helped students develop computer programming skills and tools to analyze and visualize the data. Empirical Modeling Analysis, instructed by Dr. Todd Abel of the Mathematics Department, introduced students to statistical modeling and helped them utilize the tools to develop and carry out experiments. Biology faculty Dr. Krista Peppers taught Toxicology & Microscopy to help students develop microscopy skills and implement their own investigation into whether ethanol impacts the heart rate for Daphnia magna, the water flea.

Students implemented the knowledge and tools gained over the course of the week, to conduct experiments and come up with resolutions based on the data found. On the last day of research, the students divided up into groups and presented their findings to their peers, parents and faculty/staff. All four groups agreed that the introduction of ethanol slowed the heart rate of the Daphnia magna and the higher the concertation of ethanol, the slower the heartbeat. Once the water fleas were reintroduced into water without ethanol, the heart beat quickly recovered and returned to normalcy.

The students stated they had an amazing time and learned interesting things about water flea. The students hope to use the knowledge, tools and experience gained from this program to help them in future discoveries.Math Admin Assistants Mrs. Jennifer Jones and Mrs. Leitha Smith, and a math graduate student Eddie Gallarno provided additional support for the program.
