From Feather to Feed
The poultry industry produces millions of tons of feather waste annually. A soil microbial consortium was isolated and the ability of these microorganisms to degrade chicken feathers was investigated. The results demonstrated that microbial conversion of feathers is a biotechnological process that improves the utilization of feathers as feed. 2006 Project Report.

The Factorial Factor The purpose of the experiment was to investigate whether card sleeves had an effect on the shuffling of a deck of cards. Results were measured by using “Rising Sequence” and “Adjacent Pairs” to evaluate randomness. Card sleeves were found to affect shufflers with an inverse proportion to the shuffler’s skill. 2006 Project Report. |

2006 Project Inhibition of C.Difficile Clostridium difficile-related disease is an emerging health concern. We examined the effects of alternative treatments such as probiotic and antibody-rich products on toxins and growth of C. difficile. Results showed that both probiotic-related products and bovine colostrum neutralised C. difficile toxins, while only probiotic-related products inhibited bacterial growth. 2006 Project Report. 2004 Project Attack of the Enemy Mutants! I studied the development of antibiotic resistance in a strain of Staphylococcus aureus. The rate of development of resistance to each of nine antibiotics commonly used to treat such infection was determined. Further investigation examined loss of acquired resistance and factors affecting numbers of exposures needed for resistance to develop. 2004 Project Report |

Antibacterial Toothpaste - Do Not Swallow
The effects of antibacterial toothpaste, containing 0.3% triclosan, on the probiotic lactobacillus (HA-111) bacteria, found in the human gastrointestinal tract, were investigated. Zones of inhibition appeared around filter paper disks inoculated with Colgate Total antibacterial toothpaste that were plated on blood agar plates, swabbed with lactobacillus isolate. Inhibitory zones continued to grow for 24 hours, 12 hours longer than the toothpaste’s claimed effectiveness. 2006 Project Report. |

Put a Spin On It Four kinds of balls were spun at various rates and exposed to varying wind speeds. The pressure differential between opposite sides of each ball was measured. As the rate of spin increased, the pressure differential increased. As the wind speed increased, the pressure differential increased quadratically. 2006 Project Report. |

Gold, Silver and Bronze Medals are assigned to the top
projects in each division and category. Medal awards are based on marks
assigned by the judges therefore there are times when not all medals are awarded.
There are many other awards at the CWSF which vary yearly. Up to date information is available from YSF Canada |
In each of the three age Categories in each of the six Divisions, the following general guide is used:
