Science – scientia (Latin) which means knowledge. * A systematized body of knowledge that seeks to answer questions about the natural environment; study of organized facts, which have been discovered about the environment. * Look at it, think, guess, and try it out.
Technology – also known as applied science. * A consequence of science and engineering. * Deals with man’s usage and knowledge of tools and crafts and how it influences man’s ability to control and adapt to his environment. * Systems, methods, or techniques.
Science’s ultimate goal: to give humanity an understanding of the underlying principles about the phenomena happening in nature.
Scientific Method – a step-by-step method used in answering problems encountered in the natural environment.
Steps in the Scientific Method:
1. Observation – anything that is sensed in the environment
Ex: 5 senses, The smell of flowers, Color of the leaves…
2. Problem – a question formulated from the observations made from the environment
Two forms:
a. Narrative Problem b. Interrogative Problem
3. Hypothesis – a preliminary answer to the scientific problem based on observation and related literature; an educated guess.
4. Experimentation – a procedure done to test the validity of the hypothesis. a. Variable – anything that can be changed in the experiment. Control – a variable that is kept constant Independent – a variable that is changed to elicit the desire response Dependent – the variable that is being observed b. Group – a cluster of individuals in the experiment that has the same variable. Control group – the group in the experiment that is kept in its natural state Experimental group – the group in the experiment that is changed
5. Conclusion – the generalization that is based on the analyses made on several data obtained in the experiment.
