Meagan FabelMeagan Fabel was born on May 10th, 1996 and is now a grade eleven student at Walkerville Collegiate Institute in the WCCA enriched arts program, in Windsor, Ontario. With teachers as parents, her early childhood developed her keen sense of curiosity and her strong desire to be environmentally friendly. Meagan has always had a keen interest and passion for science, math, and the environment. Meagan also participates in extra-curricular activities such as competitive figure skating, highland dancing, and music. Her career goals reflect her passion for science and math and she hopes to become a university professor for math and science education. Meagan has successfully competed at the Windsor Regional Science Technology and Engineering fair eight times previously, and is proud to represent her school and city this year at the Canada Wide Science Fair.

The introduction of Synedra diatoms into a Grätzel cell was examined, testing six independent variables (amount of diatom solution, growth solution, titanium dioxide solution, counter electrode preparation, type of pigment, and type of solar cell) to optimize electrical energy produced. Results indicated that the integration of Synedra diatom frustules into the Grätzel cell increased the voltage by 5.9 times compared to a regular Grätzel cell.
