Science projects have come a long way from creating a solar system using Styrofoam balls.

Things have changed. Wait until you see some of the latest science projects from some Orange County students.

"I thought toilet seats were going to have less bacteria than cell phones," one student said.

Now that's a theory most people don't think of. Yet some of these science projects continued to dig deeper into the world of science.

"I basically wanted to see if I could find a way to diagnose bipolar disorder using handwriting," said Evelyn Velez, a junior at Wekiva High School.

"My project deals with studying the interactions between arsenic and saleniem using e.Coli as a model system for human system," said Daniel Cook, a senior at Lake Highland Prep.

Cook's three year science project researches how people exposed to arsenic may cause cancer. He and more than 250 students are using the expo as platform to share their findings.

"It's also allowed me to connect concepts that I've learned in the classroom to real world applications and solve real world problems," said Cook.

Becky Anderson is now a judge but she says she knows what its like to be in the students shoes. She was there 20 years ago.

"A lot of them are focusing on are they right or not in their hypothesis, and others are focusing on the whole package, their whole presentation and what could be next,” said Anderson.

With the way technology is evolving these days, so are the look of science projects. A digital picture frame is now becoming more commonplace in science presentations.

"I loaded a PowerPoint that I used in a previous competition and saved it as an image file and then got to put that on the photo frame so it will update and play a little slide show during my board," said Charles Doyle, a senior at Lake Highland Prep.

Before we know it, some student is going to create a digital science board, replacing the cardboard variety.
