From the Latin word "Knowing" is a process for producing knowledge. Depends on making precise observations of natural phenomena on formulating reasonable theories to make sense out of those observations. It provides information about both materials and mechanisms in the world around us, it can help us find practical dolutions for many problems.

From a French word "Environner; to encircle or surround can be defined as; Circumstances and conditions that surround an organism or group of organidms; The social and cultural conditions that affect and individual or community

It is the systematic study of our environment and our place in it. Highly interdisciplinary which integrates information from biology, chemistry, geography, agriculture, and many other fields. It is mission oriented; it implies that we all have a responsibility to get involved and try to do something about the problems that we have created.

It involves drawing a conclusion based on a number of observations. It moves from specific to general. It begins with the observation of specific events, and this eventually leads to the formulation of general statement about what observation means.

It involves drawing specific conclusions from some larger assumptions. It moves from general to the specific, from broad idea to one or more specific statements to reach a general conclusion. Logically leads to predictions which are often described as a form of "If... Then" reasoning.

A logical sequence of thought processes and activities designed to gather information and test ideas.

Develop a question or problem based from the observed event or natural phenomenon. The defined problem should be limited in scope and properly defined to be manageable and to be able to come up with the significant solutions to it.

Design a temporary working explanations or tentative solution to your problem. The hypotheses are usually based on prior observations or derived from theories based on such observations.

Gather data related to the stated hypotheses. Data could be qualitative (data can be perceived y the senses, such as color, texture, taste, gender, etc.) or quantitative (numerical data such as height, weight, age etc.

Perform further observations and experimentations to test the reliability and validity of a hypothesis. Reliability is the "Consistency" or "Repeatability" of your measures or is concerned with the accuracy of the actual measuring instrument or procedure. Validity on the other hand is concerned with the study's success at measuring what is set out to be measured.

Draw a conclusion from the analyzed data. A conclusion is a statement whether the hypothesis is accepted or rejected. Such conclusion must be purely based on facts demonstrated in the experiment.

If the experimental evidences continue to support the hypothesis, that is the time it becomes a "_________".

As more and more evidence comes in that is consistent with a given theory, the explanation may become virtually irrefutable and is called "_______".

It states that the force of gravity acts between all objects in the universe.

Is a process by which people develop awareness, concern, and knowledge of the environment and learn to use this understanding to preserve, conserve, and utilize the environment in a sustainable manner for the benefit of present and future generations.

From the Greek "oikos" meaning House or Dwelling, and "logos" meaning discourse, is the study of distributions, abundance, relations, and the interactions of organism with each other and their environment. It is the study of ecosystems.

It describe the web or network of relations among organisms at different scales of organization.

A group of individuals with the same gene pool or genetic characteristics and is capable of interbreeding with one another.

A group of same species occupying a specific geographic area and time.

A group of different populations distributed into specific geographical area.

Different communities working as a unit, interacting with both its physical and biological environment.
