Elephant’s Toothpaste Experiment
Introduction:
A chemical reaction is a process in which atoms of the same or different element rearrange themselves to form a new substance. There are 7 ways to tell if a chemical reaction has occurred; if there are gas bubbles forming, if a precipitate is forming, if the colour has changed, if the temperature has changed, if the volume has changed, if it is giving out light and if there is a change in smell or taste. In a chemical reaction heat is either absorbed (endothermic reaction) or given out (exothermic reaction) (Houghton Mifflin Company, 2005). An exothermic reaction is a chemical reaction in which energy is released in the form of heat whereas endothermic reactions are reactions where the temperature
