Doing science projects at home with your kids can be rewarding. Have a fun time with your kids experimenting with the science project and at the same time you will be teaching your kids something new. Making crystals is a great way to teach your kids about science. This is also a science project that one of your kids can do for a school science fair.

Pour the sugar water solution into the glass jar. An adult needs to do this as the water and the pan will be very hot.
Hang a piece of string onto a pencil and place the pencil on top of the jar. The string should hang down into the sugar water but not touch the bottom of the jar. Submerge the string into the glass jar.
Wait a couple of days, up to a week, and you will soon see crystals growing up the string in the jar.
Add food coloring to the water for colored crystals.
Be careful when pouring the water into the glass jar. The water will be hot.
