Part A
Many scientists are experimenting with different electrolysis techniques but some are not as efficient as platinum catalysts which are inexpensive. Thus, this research project studies how well a low cost catalyst, cobalt, can affect the efficiency rate of electrolysis. Our aim was to improve the efficiency of electrolysis by at least 5% with the cobalt. We set up a control set up of normal electrolysis vs one with cobalt nitrate added in it. We then calculated the final efficiencies. We managed to achieve efficiency of 7% and we proved that even cheap catalysts can be efficient. This opens more doors in electrolysis as we can further study the rest of the elements in the periodic table. With a groundbreaking low cost element, we can then introduce hydrogen fuel cells to the world as an alternative fuel cells for fossil fuels, which are currently running out.

Part B
What shapes can make a car go faster or slower? With many different shaped cars in the industry today, this project studies how different shapes can affect the speed of the car. We hope to find the most effective shape that increases the speed of the car by having improved aerodynamic shape.  Improvements to the aerodynamic flow of the car will have many benefits such as reduced fuel consumption, favourable comfort characteristics such as better cooling and ventilation, increased speed and mobility for the car.We found out that the shape that is formed like an airfoil is the fastest when attached to a model car. With its pointed hull and streamlined shape, it can be implemented to many vehicles of the future, such as racing cars and planes,  achieving the maximum speed for all speedy vehicles.
