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.  They are
presented in meetings and conventions.  

Other scientists then review them.  This is called Peer Review

Interdisciplinary Science means incorporating all different
types of science.

The control in an experiment is something that the experiment
