An object that is changed and can be changed back like silly putty.
Chemical change is when an object is changed and cannot be changed back. ex. egg cracking
actually it is a CHEMICAL change...because physical means you cant reverse the compounds like plaster of Paris mixed with vinegar turns hard but is an experiment that you cannot reverse back!! xxx

Time in physical science is not defined as a change in position. Time is a measure of the duration between two events, independent of any position changes. Position is typically described in terms of space or distance.
Physical
a variable can be described as a scientific change
