Sites and resources for children and teens under the age of 18 dealing with general scientific topics.

Science can be defined as a process of recording data from controlled experiments, summarizing the results and then attempting to develop a rational theory to describe these results. Not all experiments lead to a successful theory, but yield results that cannot be summed up in a useful way.

Science fields include biology, chemistry, physics, astronomy, earth sciences, environmental studies, and technology.

Math is closely related to science and is a necessary component of most sciences. Most branches of math do not conduct experiments, so that is why it is listed in a separate section.

The applications of successful scientific theories and applications can be astonishing. Without science, there would be no detailed environmental knowledge, electricity, space travel, air conditioning, cars, or washing machines.

There are also, some negative affects from science, such as the development of nuclear weapons and non-biodegradable plastics.

We, as a society, have choices to make on how to use these scientific developments.

To measure is to compare the dimensions, quantity, or capacity with a standard. There are several systems of measurement. The two used most often are called the English and the metric systems (also called SI, or The International System). In the United States, the English system is used most often. While most other parts of the world use the metric system. The basic units used in the metric system are: Length in meters (m), Mass in kilograms (kg), and Time in seconds (s). The basic units used in the metric system are: Length in yards (yd), Weight in pounds (lb), and Time in Seconds (s). The English units of measurement have many drawbacks: the most significant is in the complexity of converting from one unit to another, such as from yards to feet.

Physics is the science of the natural world in the broadest sense, dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Physicists study a wide range of physical phenomena spanning all length scales: from the sub-atomic particles from which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology).

This category is for educational and general interest websites related to Physics, its principles, laws, and applications.
