Science

 * __The__ __Scientific method__**
 * 1) __**Making an observation**__- Investigating, or observing is the first step to finding a solution. After making an observation, you would ask questions challenging the theory.
 * 2) F__**orming a hypothesis**__- Hypotheses are formed by adding an inference to your observation, and determining to continue or move on with your observation.
 * 3) **__Conducting experiments__**- Experiments can determine what is right, or wrong with your observation. There are two types of experiments. A controlled experiment is when only one variable is changed, which makes it easier for the scientist to diagnose the problem.
 * 4) **__Analyzing Data-__** Once your experiment is complete, you collect your data and analyze it to see if your hypothesis is true, or not.

Goal of Science
**The goals of science are to be able to interpret different happenings in our natural world, and to predict what can happen. New developments in science can generate new technology.**     

Observation
An

observation is either an

activity of a

living

being which consists of **//__r__////__eceiving knowledge of the outside world__//** using the

five senses <span style="background-color: #404040; display: block; font-family: 'Arial Black',Gadget,sans-serif;">

Inference
An inference is when you use the information you know to make a conclusion on the observation. Observation is the act of using the 5 senses while inference is the use of logic to make conclusions from observed data **<span style="background-color: #ffffff; background-position: 7px -16px; border: 1px solid #dddddd; color: #aaaaaa; display: block; float: left; font-size: 0.9em; margin: 0px 8px 0px 0px; padding: 3px 8px 3px 28px; text-decoration: none;">[|Great Answer] ****<span style="background-color: #ffffff; background-position: 7px -55px; border: 1px solid #dddddd; color: #aaaaaa; display: block; float: left; font-size: 0.9em; margin: 0px 8px 0px 0px; padding: 3px 8px 3px 26px; text-decoration: none;">[|Not Helpful] ****<span style="background-color: #ffffff; background-position: 4px -77px; border: 1px solid #dddddd; color: #aaaaaa; display: block; float: left; font-size: 0.9em; margin: 0px 8px 0px 0px; padding: 3px 12px; text-decoration: none; text-indent: -2000em;">[|Report] **



Hypothesis
What is a hypothesis? - a hypothesis is an educated guess, or a tentative statement that can be a

possible solution to an unexplained event. A hypothesis is a testable statement. It can be proved or disproved. -unlike a theory a hypothesis isn't an

exact prediction .

How do I write a hypothesis? - to write a hypothesis you use words like //if// and //then.// This creates an if and then statement which is necessary to write a hypothesis.



Manipulated Variable
- In a controlled experiment 1 variable is changed ( the manipulated variable ﻿ or independent variable ) -

Located on the x-axis ~ For example, if you were measuring the growth rate of plants under full sunlight for 8 hours a day versus plants that only have 4 full hours of sunlight a day, the amount of time per day of full sunlight would be the independent variable - the variable you control
 * The independent variable is what you, the experimenter, changes or enacts in order to carry out your experiment


 * There can only be **1** independent variable in any valid controlled experiment (in some more advanced forms of research there may be more than one but in a regular experiment, you should only have 1)

==Responding Variable : <span style="display: block; font-family: Verdana,Arial,Helvetica,sans-serif; font-size: 12px; font-weight: normal; line-height: normal;">The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable. ==


 * The responding variable is also know as the dependent variable in an experiment.
 * <span style="display: block; font-family: Verdana,sans-serif;"> The variable that is observed and that changes in response to the independent variable is the dependent variable.

Record & Analyze Data


It is important to record and analyze data because it helps people keep track of their experiment and helps them move forward. Analyzing is a good way to double check your work and catch mistakes. Recording helps you know what happened in the previous test to help you know what the next step should be.
 * __Analyzing__** - To examine critically, so as to bring out the essential elements or give the essence of.
 * __Recording__** - To set down in writing or the like, as for the purpose of preserving evidence.



Theory= explains observations ( How and why) nature works.
1. Is what one or more hypotheses becomes when they have been verified and excepted to be true 2. An explanation of a set of related observations or events based upon proven hypotheses and verified multiple times by detached groups of researchers. 3. Some scientists even use the term theory for the term hypothesis, which confuses many people. 4. Part of the scientific method. Source: www.wilstar.com



Natural Law
1. Natural law is a theory that justifies the existence of a law whose content is set by nature. 2. A theory that has been tested many times and found to always be true. An example is the Law of Gravity.
