Aim: We will continue to understand the basics of Earth Science
by reviewing the chapter and preparing for Monday's Quiz Std 4- Science concepts When we light a candle, we are affecting the wick. We have actually changed the wick to now be on fire. This is the independent variable. What we change.... As a result of this change other things happen, the wax melts, the candle gives off light, the candle gets softer, it gives off heat... These are all dependent variables. They are dependent upon the independent variable otherwise they do not happen! PRECISE--- This means exact measure--- We are interested in accuracy! We are physically able to see a model- it helps us to picture and understand and predict. Once we have results of an experiment, we publish them so that other scientists can see them, learn from them, use them and perhaps test them further. Results are published in journals and magazines.
