chemical change

In a chemical change, the actual chemical makeup of a material is changed, and you cannot get the original material back without another chemical change. Burning wood is an example--you end up with ash and various gases (with heat as a byproduct), but you cannot undo the change to get your wood back.

In January 2013 the Explorers investigated the differences between “physical changes” and “chemical changes,” culminating with the club members digging their hands into the details of a particular chemical change—literally.

The Explorers spent some time at the end of January examining the difference between physical and chemical changes, with some markedly gooey results.

In January 2010 the Explorers investigated the difference between “physical changes” and “chemical changes,” demonstrating a chemical change with a combination of plain old glue, water, and a powder known as borax.

The Explorers started by discussing the difference between the two types of changes that a substance can undergo—an especially pertinent topic since the fourth graders have been learning about that very thing in science class.
