Science with Crayons (makes great gifts too!)

 

What you need: 

old crayons (with wrappers removed)

a silicone candy mold (we used a Lego one)

Steps:

Place broken crayons into molds – smaller molds you may need to chip the crayons into smaller pieces, this mold was nice b/c I could put them in in bigger chunks!

Put on a baking tray in oven at 250 degrees for 30-45 min (until the crayons have all melted and they are a liquid).  This is where the science comes in!  I have to say, not all crayons are made equally, some do not melt as nicely, Some the wax separates, etc.  It’s fun for the kids to  make observations.  Some may even want to watch through the glass front on the stove.

Remove from oven and allow to FULLY cool before removing from the molds. (another science observation)

These make great gifts too, bag them up in some cute baggies and tie with ribbon!  Little kids will love them!  My son will be gifting these to his preschool co-op classmates. 

You can even make this more science involved by filling out a science lab form or documenting in a science notebook.

  3. This is a cute idea. I love that you made it into a science lesson and that they can be used for gifts. Now, if my children would stop LOSING the crayons.
