| Josh - Josh, a grade 7 student from Toronto, basks in a host of diverse interests. Along with sports, such as hockey and basketball, Josh enjoys playing the trumpet, investigating world issues and giving back to his community. He and his partner, Christopher, decided to explore the efficacy of alcohol in mouthwash on oral bacteria after wondering why some mouthwashes contain alcohol and if, in fact, alcohol was necessary. Their results have prompted them to create their own mouthwash in the hopes that it will be a healthier mouth washing option for them and their friends. Josh has learned a lot from his project and encourages other students to act on their own inquiries and obtain answers that will contribute positively to society. Josh is honoured to be representing the city of Toronto at the CWSF in Fredericton along with his partner, Christopher. He is very much looking forward to meeting and learning from other budding scientists from all over Canada. | | Christopher - Christopher is a grade 7 student from Toronto.

The ABC's of Mouthwash
| Challenge: | Health | | Category: | Junior | | Region: | Toronto | | City: | Toronto, ON | | School: | Upper Canada College | | Abstract: | Test subjects swished water, non-alcohol-containing mouthwash and alcohol-containing mouthwash after eating. Swabs taken before and after swishing were swiped in petri dishes and incubated for 48 hours. Bacterial colonies counted revealed swishing with water increased oral bacteria and both mouthwashes are equally effective at deceasing bacteria. Therefore, it is unnecessary to use alcohol-containing mouthwash to obtain an optimum antibacterial effect and risk possible side effects. |
