Water is the very essence of our earthly existence. Every creature, and the ecosystem they thrive in, are majorly composed of water and depend on water for its daily functions. As a result, water...

The greenhouse effect is, in simple terms, atmospheric conditions that keep the earth warm. Gases such as water vapor (H2O) and carbon dioxide (CO2) create a sort of atmospheric glass that keeps...

Water drums were first used by Native Americans during religious and ceremonial practices to keep time with tribal songs. In Native American culture, it is one of the more respected instruments...

Bach Flower Remedies (also called Flower Essences) are tinctures made from flowers and a water/alcohol mixture. Some people believe these tinctures help them balance their emotions. Each flower...

When children enter middle school, they take on the beginnings of a curriculum in science. They study rudiments of chemistry, biology, botany, archeology, meteorology and animal science. Assigning...

To understand the role of living organisms in the water cycle, you must first understand the general processes of the water cycle and its non-living components. The three main steps of the cycle...

Sea water is undrinkable due to its high salt content and any process that removes the salt from saltwater is known as desalination. A commercial desalination plant typically produces pure water...

For deep wells, it can be difficult to determine the depth of the water because you cannot see the bottom. However, using physics it is possible to calculate the depth of the water because once...

Glucose is a simple sugar also known as blood sugar, corn sugar and grape sugar. Living cells use it as a source of energy and it's one of the primary products of photosynthesis. Pure glucose is a...

Life on our planet evolved in water. "Biology" textbook authors Helena Curtis and Sue Barnes estimate that by weight, water constitutes 50 to 95 percent of "any functioning living system." Why?...

This water purification system works through evaporation and condensation. Using the heat of the Sun (or a heat lamp), the water contained in whatever brackish, muddy liquid being purified...

This is for a science project about density that I came up with in school to show how it works using liquids. You will be taught how to do it yourself for that perfect grade. You will learn how to...

Eliminate particles and other pollutants from your water with an easy, cheap water filtration project. Get in touch with nature by re-creating the natural process of filtering water through gravel...

Water is a simple molecule with profound physical and chemical properties. One property, its ability to split into two ions (ionization), provides us with a method to determine the acidity or...

A sand table is a sandbox on legs. Sand tables have become a ubiquitous feature in elementary school classrooms, but there is much more teachers can do with sand tables than let students push sand...

Growing crystals is an excellent science experiment for children ages 8 to 12. It teaches children about saturation as well as how crystals form. The project can be completed in one day, but the...

The pH of water tells you how acidic or alkaline a solution is. The pH scale ranges from zero, which is very acidic, to 14, which is very alkaline, with a pH of seven being neutral. The pH scale...

Most of the water we drink was rain water at some point in time. Regardless of where you live, rain water is safe to drink as long as it has not come into contact with anything.

Surface tension is a property of water in which the molecules of water on the surface of the liquid is attracted to each other. The surface tension of water allows objects of greater density to...
