THE SCIENCE OF MELTING CRAYONS

There are two types of changes called reversible change and irreversible change. Melting crayons, like melting ice is a great example of reversible change. Reversible change occurs when something is melted or frozen for example, but the change can also be undone. Just like with our crayons! They were melted and reformed into new crayons. Although the crayons have changed shape or form, they did not undergo a chemical process to became a new substance. The crayons are still usable as crayons and if melted again will form new crayons! Baking bread or cooking something like an egg is an example of an irreversible change. The egg can never go back to its original form because what it is made of has been changed. The change cannot be undone! Can you think of any more examples of reversible change and irreversible change? ALSO CHECK OUT: How To Make LEGO Soap

HOW TO MAKE LEGO CRAYONS

Adult supervision is highly recommended. The melted crayons will get very hot! STEP 1. Preheat oven to 275 degrees. STEP 2. Peel the paper off the crayons and cut or break into tiny pieces.

STEP 3. Fill each LEGO mold with different colors, anything goes! Similar shades will create a nice effect or try color mixing by combining blue and yellow.
