Zoology Project Ideas

In most simple words zoology is the science of study animals in their natural environment.
Nervous System:
1.Detail study about the role of each and every component of nervous system.
2.Design nervous system computer animation which shows function of each and every part of this system.


Reptiles:
It includes tortoises, turtles, snakes, lizards, alligators, crocodiles, and extinct forms.
1.You can conduct study on any of the above reptiles about their habitat, movement or classification.
2. Kids below 5 can also build paper reptiles to understand the basics of designing and movement of reptiles. For ex. If they build snake they need to build its tail in series with combination of rings fitted into one another to make a flexible ligament so that it looks and move like snake.

Animals:

1. Do animals have memory, smell senses or color distinguishes capabilities? Do some experiments to find out that and record your findings with data.One of the best way to do it is by constructing maze.

2.Study Animal's Populations in different environment and what are the reasons for their population growth at one place more than other place.Moreover, you can also study whether population growth depends only on availability of food or their are some other factors involved in it.

Hydroponics System

Hydroponics is a method to grow plants without soil.As demand of food is increasing, we need to find ways to grow vegetables and fruits in whatever way possible.

Why do we need Hydroponics way of irrigation?

Limitation of land ,weather dependence and transportation cost are the factors because of which we should shift our focus from traditional methods to Hydroponic.Further more, we can grow more than one crop in same  bag has great economic benefits.Research done by University of Florida found that this way of irrigation has profitable too.

In the colder part of the world,it is difficult to grow plants in winter because of lack of sunlight and harsh weather conditions.This method can be used to mitigate these cumbersome problems.
Advantages:
No need of Pesticide and Insecticides
No Soil Required
Crops are easily to transfer
More plants per unit area.
Water stays in the system and reusable.

Procedure:

Do it yourself at home  : This page contains method and procedure required.

Generating Electricity from Waste water

Tons and tons of waste dumped upon our mother earth each day. This waste not only causes damage to our environment but has health risk too. To use this water again, our governments are using water treatment plants. Project Idea we are going to discuss today would use these plants to power our homes.

How?

We all know that, in nature different materials biodegrade at different rates. It is a chemical dissolution of materials by bacteria or other biological means. Bacteria in the presence of oxygen produce carbon dioxide and water, but when we stop the supply of oxygen they start to produce electrons and protons.  They were first found by Professor M.C. Potter in 1911. When we use them to generate electricity in a cell, this cell is called as Microbial fuel cell.

What is Microbial fuel cell?

It consists of anode and cathode separated by ion exchange membrane. Ion exchange membrane allows exchange of ions between two electrolytes.

We had discussed about microbial fuel cell before. Today we will discuss how waste water can be used to feed the fuel cell while treating it.

How it works?

Waste water is placed in an isolated chamber to stop oxygen entering it, thus compelling the micro-organism to use anaerobic respiration. As a result, bacteria start producing electrons. These Electrons are transferred to the cathode compartment through an external electric circuit, while protons are transferred to the cathode compartment through the membrane. When we put resistance between them, we can produce electricity.
Explanation given in a video below would help you to understand this concept better.

Microbial fuel cell

A microbial fuel cell (MFC) or biological fuel cell is a bio-electrochemical system that drives a current by mimicking bacterial interactions found in nature.A microbial fuel cell is a device that converts chemical energy to electrical energy by the catalytic reaction of microorganisms.


According to BBC Science and Environment ,US researchers say they have demonstrated how cells fueled by bacteria can be "self-powered" and produce a limitless supply of hydrogen.Microbial fuel cells hold promise as a new source of electricity by their unique ability to generate an electric current from waste products.

Modeling the processes in microbial fuel cells could pave the way for improving the voltage output and take us one step nearer to using these devices to produce electricity.

How Microbial Fuel Cell works?

We all need food to survive, in the same way, bacteria needs energy to survive.

 Bacteria get this energy in a two-step process :

The first step requires the removal of electrons from some source of organic matter (oxidation).

The second step consists of giving those electrons to something that will accept them (reduction), such as oxygen or nitrate.

If certain bacteria are grown under anaerobic conditions (without the presence of oxygen), they can transfer electrons to a carbon electrode (anode). The electrons then move across a wire under a load (resistor) to the cathode where they combine with protons and oxygen to form water. When these electrons flow from the anode to the cathode, they generate the current and voltage to make electricity.

Hydrocarbon Fuel Processing in Solid Oxide Fuel Cell

SOFC is a solid state device that produce electricity directly from oxidizing a fuel at elevated temperature. It consists of porous ceramic anode,electrolyte(dense layer of ceramic) and cathode as thin porous layer. It uses ceramic electrolyte with inexpensive catalyst at high temperature of around 700 degree Celsius and has large thermal innertia.More Info
