Ultraviolet Rays :Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3 eV to 124 eV. It is named because the spectrum consists of electromagnetic waves with frequencies higher than those that humans identify as the color violet.

Bio-Insecticides And Pesticides :
Biopesticides and insecticides are biochemical pesticides that are naturally occurring substances that control pests by nontoxic mechanisms. Conventional pesticides, by contrast, are generally synthetic materials that directly kill or inactivate the pests.

The effects of water impurities on plant growth:
It more or less depends on what type of impurities are? If impure water has harmful chemicals then it will definitely affect the growth of the plant. In this project, you need to find out about the impurities which harm plants as well as those from which plant started to grow faster.

Waste Water Management:
Water is one of the most important assets of human life. Even though their earth is surrounded by 70 % of water, a large percentage of the human population is facing the problem of water shortage. With the help of effective water management, we can reduce this problem to some extent.
There are two important ways for water management :
1.Waste Water Management: The process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic.
2.Industrial Water Management

How Oil Spills Affect the life of Sea Species:
In our life, we have seen multiple occurrences of oil spills around us. Most recently world was shaken and shocked by the magnitude of the Gulf of Mexico oil spill. The effect of these spills was not much on humans with respect to animals living there.

Bio-Diesel and Bio-Petrol:
Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, animal fat (tallow)) with alcohol.
Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone or blended with petrodiesel. Biodiesel can also be used as a low carbon alternative to heating oil.

Analysis of Organic Fertilizers:
Fertilizer (or fertilizer) is any organic or inorganic material of natural or synthetic origin (other than liming materials) that is added to a soil to supply one or more plant nutrients essential to the growth of plants.[1] A recent assessment found that about 40 to 60% of crop yields are attributable to commercial fertilizer use.
Naturally occurring organic fertilizers include manure, slurry, worm castings, peat, seaweed, humic acid, and guano. Although the density of nutrients in organic material is comparatively modest, they have many advantages. The majority of nitrogen supplying organic fertilizers contain insoluble nitrogen and act as a slow-release fertilizer. By their nature, organic fertilizers increase physical and biological nutrient storage mechanisms in soils, mitigating risks of over-fertilization. Organic fertilizer nutrient content, solubility, and nutrient release rates are typically much lower than mineral (inorganic) fertilizers
Measuring Solubility of Saturated Solutions
Saturation is the point at which a solution of a substance can dissolve no more of that substance
Solubility is the property of a solid, liquid, or a gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a homogeneous solution of the solute in the solvent. The solubility of a substance fundamentally depends on the used solvent as well as on temperature and pressure.
Study the Setting of Cement
Cement sets when mixed with water by way of a complex series of hydration chemical reactions still only partly understood. The different constituents slowly hydrate and crystallize while the interlocking of their crystals gives to cement its strength. After the initial setting, immersion in warm water will speed upsetting. In Portland cement, gypsum is added as a compound preventing cement flash setting. The time it takes for cement to set varies; and can take anywhere from twenty minutes for the initial set, to twenty-four hours, or more, for the final set.

Measure the Amount of Acetic Acid in Vinegar
Acetic acid is an organic compound with the chemical formula CH3COOH. It is a colorless liquid that when undiluted is also called glacial acetic acid. Vinegar is an acidic liquid produced from the fermentation of ethanol in a process that yields its key ingredient, acetic acid (ethanoic acid). It also may come in a diluted form. The pH of table vinegar ranges from 2.4 to 3.4[1] (higher if diluted). The acetic acid concentration typically ranges from 4% to 8% by volume for table vinegar[2] and up to 18% for pickling vinegar.

A large number of people are migrating towards the city to find a better job. According to one estimate in 2030 around 60 % of the world population would live in the city. You can make a model of this project where you can show people who are migrating to cities where they are getting good jobs while leaving behind a calm and peaceful life of villages.
Global Warming :
You can make a project on global warming as well as how it is affecting our earth. If you want, you can explain the factors due to which global warming takes place.
