Step Up The Power

Student: Nathan McNally

District/Region: Annapolis Valley Region

Event: 2013 Canada-Wide Science Fair

Grade 8 - Kings County Academy

Much of the energy humans normally expend goes to waste. To recover some of this energy, I created a floor tile that transforms kinetic energy into electrical energy using magnetic electric generators from hand pump flashlights. Each step made a small amount of electricity which I could store and use. With improvements, tiles like this could become a practical way to harness already existing energy.

Les Télomères

Student: Nathan Robichaud

District/Region: Tri-County District

Event: 2013 Canada-Wide Science Fair

Grade 7 - Maple Grove Education Centre

My Science Fair is based on the possibility and probability of the manipulation of a microbiological enzyme called telomerase, which could lengthen telomeres and make you live longer and possibly help against developing cancer, as a cell can commit apoptosis, or become a cancer cell, which lengthens telomeres, which saves the life of the cell. I explain telomeres and my theory, and life expansion.
