Title:
Compilation of Computations
Summary:
Will attempt to determine if, and by approximately how much, the reorganization of how a value is
calculated, will effect the amount of time to complete the necessary computations.
More specifically:
A mathematical formula will be developed to determine a value. In this case, we are going to find
the rate of acceleration of an object, and use it to find the force required if that object has a mass of
3000kg.
A program will be written that uses four data points, where x=t and y=d. In this way, this program
will be given the position of the object at any give time. This value will be found two different ways:
1) Each running calculation will be stored in a variable.
This program will be required to calculate the distance between the points.
It will use the distance, and the time between them, to find the speed.
It will use the change in speed to find the rate of acceleration.
Than that value will be multiplied by 3000 to determine how many Newtons of thrust is required to
achieve the position time data given.
2) A 'master' formula will contain all the computations needed, using all 9 bits of data, to determine
the force needed. This formula is derived below (more detail available on worksheet):
a=v/t
v=v2-v1
t =t2-t1
v=(d2-d1)/(t2-t1)
F = ma
Therefore: a = {3000}{[(d4/t4)-(d3/t3)-(d2/t2)+d1/t1)]/(t4-t2)}
The program will run each method 10,000 (or more as needed) and return the amount of time that
was required for the computations. This will be done several times to ensure consistency with
regards to the data returned.
This program will be produced a number of times, using a variety of platforms and methods:
-VB; -C#; -Python
Upon final analysis of the results, I intend to determine the percent difference in computational
time.
As a possible project expansion, different applications of this theory could be used, such as
calculating the position of a player with a specific input.

Title:
From Bacteria to Hydrogen
Summary:
Many industries are looking for novel ways to create energy. One place where they may overlook is
wastewater. In wastewater there is an abundance of bacteria that can thrive without oxygen.
Knowing this an experiment was developed where anaerobic bacteria will be used to run a
microbial electrolysis cell. The purpose of this experiment will be to show how anaerobic bacteria
will be able to create a fuel source. It is hypothesised that if anaerobic bacteria are used in a
microbial electrolysis cell then the result would be the production of hydrogen gas.
A majority of our method is based solely on the creation of the microbial electrolysis cell since that
is the main component of this experiment. Two airtight containers of the same volume will be used
to create the two chambers of the cell. Carbon was used as the electrodes and two AA batteries
were used to supply additional power to the cathode chamber. The salt bridge, which will carry the
H+ ions created by the bacteria to the cathode chamber, was made with a pipe containing a gelatin
and salt solution.
At this point in time the experiment is still in progress. Therefore our results, analysis and
conclusion will be presented at the fair itself.

Title:
Down the Drain: An Alternate Approach to Microbead Filtration
Summary:
Microbeads are tiny bits of plastic used for their exfoliating properties in consumer products. They
are found in soaps, scrubs, and sometimes even cosmetics or toothpaste. They are defined as less
than 5mm, although most found in products are smaller than 1 mm. Most microbeads are usually
made up of polyethylene, but can also be made of polypropylene, polyethylene terephthalate,
polymethyl, methacrylate, and nylon. Unfortunately, these microbeads can be found in high
concentrations Ontario's Great Lakes. Since they do not degrade, the amount of plastics is
accumulating rapidly. Larger pieces break into smaller pieces from UV radiation and water
currents. This makes them increasingly difficult to filter out by conventional means. Due to their
small size (therefore large surface area), plastics that make up beads will readily absorb potentially
carcinogenic pollutants. Aquatic organisms, such as plankton and fish will eat these beads, putting
the animals at risk, as well as human health. Due to their ubiquity, there is a good chance that
polluted microbeads will end up on dinner plates across the country.
My project will attempt to filter out these harmful micro plastics by giving them a negative charge,
then using a positively charged surface for extraction. This concept mimics that of an electrostatic
precipitator. I have several design ideas that I hope to test, although only one system will be built. I
will gather data in order to calculate efficiency of the filtration techniques, all while tweaking
variables in order to maximize efficiency. From there, I will be able to model the data in order to
draw conclusions about the feasibility of my design. Unfortunately, there have been difficulties in
the process of isolating the microbeads from consumer products, so the project will most likely
have to be done at a larger scale (I.e. using larger bits of plastic to mimic the microbeads). But this
will have several benefits. The results will be easier to observe at a larger scale, and it will be
easier to standardize the microbeads (or whatever is used in place of them).

Title:
2 Dimentional Environment Mapping System (2DEMS)
Summary:
The goal of the project is to create a device which can detect people (or things) as well as the
layout of its surroundings and remotely send this information to the user who may be else where in
the form of a map which will include a scale compass. The main inspiration is that we enjoy
paintballing and with a device that can tell you where an opponent is remotely will allow you to
sneak up on them already knowing where they are and the layout of their surroundings alowing you
to get them every time without even seeing you. In order to make the device that does this we have
created a proof of concept involving a rotating camera and laser which along with the programing
of our palm sized computer acts as a rangefinder and then sends the data to another device and
from there creates a 2 dimentional map. If the program we make turns out as we hope we will be
able to see the size and dimentions of the room along with a new map update every few seconds
essensialy making this it a lidar. This also as makes for a very useful tool in many realworld
apliacations which humanity is on the verge of including self driving cars new assistance systems
for the blind and military purposes.

Title:
Oil Spills: The Magnetic Connection
Summary:
For this science fair project, I am creating ferrofluid with different 5 different types of oils, then I am
simulating an oil spill in a 100 mL beaker using water and vegetable oil, after I am going to drop
ferrofluid into the oil spill and this will in turn magnetize the oil. After magnetizing the oil, I will be
using a neodymium magnet to collect the oil and ferrofluid to effectively remove the oil from the oil
spill. I will be comparing the amount of oil placed in the oil spill to what is left after cleaning with the
magnet to see the effectiveness of the different formulas. This science fair project introduced
nanotechnology to a disastrous event like an oil spill. it offers a easy way to clean oil spills that can
be revolutionary. By seeing which ingredients optimizes the ferrofluid, the materials used to make
ferrofluid to clean oil spills can be more effective.The reason I chose this topic is because I see the
impact oil spills have on the environment and I also notice how disastrous the cleaning efforts is. I
believe it is on the habitants of earth to take a step to protect the land in which we live and this is
perfect way to do that.

Title:
Charged with a Salt and Battery
Summary:
Research Question: How does a change in concentration of Copper (II) sulfate solution affect the
voltage produced in a galvanic cell.
Background information: During a redox reaction, one substance loses electrons while another
substance gains electrons. Electrons are transferred from a substance that is oxidized to another
that is reduced.
In this investigation electrons are transferred from a zinc metal to the aqueous copper II ions. This
reaction occurs spontaneously, releasing a small quantity of energy. By separating the oxidizing
and reducing agent and putting it through a wire this energy can be harnessed.
Cell potential varies depending on the concentration of the chemicals in the cell. To study cells
easily, chemists have defined standard conditions under which cells operate. A standard cell is a
galvanic cell in which all entities are at SATP, with concentrations of 1.0mol/L for solutions.
However because this investigation analyzes the change in voltage under non standard condition
the Nernst Equation needs to be used. One of the solutions (Copper(II) Sulfate) will have a non
standard concentration.
Risk assessment:
•Copper sulfate is irritating to the eyes, skin and respiratory tract.
•Hazards and risks associated with zinc: zinc metal is a human skin irritant and is a severe fire
hazard but otherwise is non-toxic. Most common zinc compounds are not very toxic but a few zinc
salts may be carcinogens.

Title:
The Best Breakup Ever
Summary:
As society is moving towards greener alternatives for everyday things, cars and the automotive
industry has to be able to adapt in order to keep up with consumer trends. One of the green
alternatives to fossil fuel is hydrogen fuel. A problem scientists encountered when they first
produced hydrogen fuel was how inefficient the production was. It required a lot of energy and so it
ended up being only about 7.5% efficient. Catalyzing the electrolysis of water would lower its
activation energy and thus make the process much more efficient.
In my experiment I explored the rate of hydrogen production in the electrolysis of water using light
as a catalyst. My aim was to answer the question “How does changing the intensity of light effect
the rate of hydrogen production in the electrolysis of water?” Light is an interesting catalyst to use
since it is present in such abundance. In order to find out the effect of light intensity on the rate of
hydrogen production in the electrolysis of water, I used a 1 mol/ml solution of sulfuric acid. The acid
acted as an electrolyte and increased the overall rate of hydrogen production. To control the initial
rate of the experiment, the same concentration of electrolyte and voltage (20V) was used for each
trial. This experiment was carried out using Hoffman apparatus and each trial ran for 10 minutes
before I turned off the DC power supply and measured how much hydrogen was produced. The
intensity of the light was changed and I measured the light intensity for each trial using a lux meter.
The final results have not been completed and calculated and will be presented at the fair.

Title:
Don't Metal with my Cell!
Summary:
Electrolysis reactions are known as the foundation of modern industry. This is an important
technique that uses direct electric current to drive an otherwise non-spontaneous chemical
reaction. Current is passed between two electrodes through an ionized electrolyte solution and
positive cations deposit on the negative electrode. Commercially, electrolysis is used for
electroplating, extraction of metals from ores and refining.
However, impurities within an electrolyte can increase corrosion of the electrodes and reduce the
life of an electrolytic cell. On a large scale, impurities can enter the electrolyte from the electrodes
which can have a negative effect on the performance of the cell. Due to the possible deterioration
of future raw materials and the pursuit of efficiency, the study was designed to determine the effect
of impurities within an electrolyte on the current density of an electrolytic cell. The evaluation of
current density provides a means of assessing the optimum current densities that yields optimum
mass-transfer conditions.
An electrolytic cell with copper electrodes with a copper sulfate electrolyte was set up. Silver is a
common impurity that is known to decrease the current density and various amounts of soluble
silver nitrate were added to the electrolyte. It is hypothesized that as the amount of silver nitrate
within the copper sulfate electrolyte increases, the current density will decrease. Distance between
electrodes, voltage, concentration of electrolyte, temperature and area of the electrode were
controlled. Observations and results have not been completed but will be presented at the fair.

Title:
The Copper Lining
Summary:
The question which acts as the base of my science fair project is how does the concentration of
copper sulfate in an electrolytic cell affect the amount of copper deposited onto the copper
cathode?
Electroplating is done through a process of redox reactions which occur in an electrochemical cell.
In the specific cell that I am experimenting with, the sulfate Ions within the diluted copper sulfate
solution reacts with the solid copper that makes up the copper anode in a reduction reaction. In this
reaction, the copper which makes up the anion releases two electrons to become copper (II) ions,
which are then released into the copper sulfate solution. The two electrons released are sent to the
anode side, where an oxidization reaction occurs. In this oxidation reaction, the two electrons that
are sent from the anode react with the surrounding copper (II) ions from the copper sulfate
electrolyte. This creates solid copper which is then deposited onto the cathode.
At the time of submitting this proposal, I am in the process of collecting my results for this project
and have not yet reached my final conclusion. However, the experiments are underway and will be
finished well before the science fair begins.
