How to Use The Carbon Footprint of a Household | ScienceSkip

A household’s carbon footprint is an estimation of that home’s greenhouse gas emissions. Calculating the carbon footprint of any household requires the consideration of a number of factors. Some environmental groups estimate that about 40% of the greenhouse gas emissions individuals are responsible for are generated at home. Eric Carlson,…

How to Use The Biology of Water Pollution | ScienceSkip

North American water quality has generally increased in recent decades, thanks to restoration programs and the creation of anti-pollution laws like the Clean Water Act. However, these actions have not come close to eliminating water pollution, which remains a serious environmental issue in both marine and fresh waters. Pollution disrupts…

How to Share The Biology of Compost | ScienceSkip

The beauty of composting is that it’s a process that bridges the inanimate world with the animate. Composting takes dead organic material, such as lawn clippings or food scraps, and through the metabolic actions of small organisms, turns it into a substance rich in the nitrogen, phosphorus and potassium that…

How to Learn The Biological Definition of Genomics | ScienceSkip

Genomics is the field of genetics that studies genomes rather than individual genes. With the advent of modern DNA sequencing technology, biologists can identify and study genomes, meaning the entire genetic code of an individual organism. When the human genome was first sequenced in 2000, scientists discovered that genetic sequences…

How to Share The Biodiversity of Deep Ocean Ecosystems | ScienceSkip

The deep ocean begins where the sunlight fades, at 200 meters (656 feet), and extends to where no light penetrates. The water contains little oxygen, and the temperature is just above freezing. Pressures reach up to 1,000 times greater than the pressure at the surface. Ocean researchers estimate 100 million…

How to make the Anatomy of a Solar Panel ScienceSkip

Photovoltaic solar panels convert sunlight into electricity. The part of the panel that actually does the absorbing is the solar cell, a thin slice of semiconductor material. But a single solar cell doesn’t provide a particularly useful amount of energy — nor is it in a particularly useful form. The…

How to share the Solar Energy to Electricity in Relation to Inflation ScienceSkip

Solar energy systems are expensive. The fuel — sunlight — is free, but the up-front investment is significant. In some places solar energy is already at grid parity — an overall cost similar, or even better than, conventional alternatives. But in many places, solar still costs more than traditional electrical…

How to share the Advantages of a Wind Turbine ScienceSkip

Compared to other forms of energy generation, wind power suffers from several challenges and disadvantages. Wind farms must often be constructed in remote areas, requiring long-distance transmission lines to transport power, and wind power is sometimes not yet cost-competitive with fossil fuels. Despite these drawbacks, however, wind power has seen…

How to share the Advantage & Disadvantage of IP Authentication ScienceSkip

Some computer applications, including email systems and Web-based scientific journals, grant access by means of the computer’s Internet Protocol network address. This method, called IP authentication, allows access to everyone in an organization, such as a university, without the need to identify each user individually. Although easy to administer, the…
