Aim- We will review the scientific method by reviewing
the stps and then putting the method to use and discussing percent of error. Standard 4- Science Concepts Review- Scientific method is a way of solving problems identify the problem gather information form a hypothesis test the hypothesis observe the test gather data draw a conclusion observations are made by using eyes, hands, smell, ears, taste (our senses) hypothesis- an educated guess based on our observations and prior knowledge Test our hypothesis- (experiment)- things might change during the experiment. constants- these are things that stay same variables- things that change independent variable- changed by the person doing the experiment Dependent variable- changes because of the change in the independent variable... I light a candle---- The change in the wick of the candle is now black and on fire (I made that happen) that change is the independent variable.... As a result of that change, the candle wax is dripping. It is giving off heat and light, it is soft. These are all dependent variables. THE DEPENDENT VARIABLE DEPENDS ON THE INDEPENDENT VARIABLE OR IT CAN NOT HAPPEN!!!!!!!!! What we are trying to test is the independent variable After an experiment.... Analyze the experiment to make sure that it was accurate.... we do this by conducting many trials Accuracy is very important if we are going to prove something. We need to use precision (exacts) We can not round numbers or guess Scientific ideas are then taken and a theory is formed A lot of people have to look at your ideas and try them...... PEER REVIEW (they test the accuracy) If a theory proves to be always correct.... we call it a law!
