science, growing crystals
By Terry Carlson

Sugar crystals
Boil water, stir in sugar until hits saturation point. Pour a small amount into baby food jars. Put a popsicle stick across the opening of the jar, hang a paper clip so it is emerged into the sugar solution.
Hang the paper clip from a string that is tied to the popsicle stick. Place next to a window. The crystals will grow onto the paper clip. Adding food coloring is pretty fun as well. Students can predict their color of their crystals.
Salt Crystals,
Same instructions as the sugar crystals. Just use regular salt. I have also used sea salt. The salt crystals will form much

faster than the sugar crystals. It is fun to do both and make predictions of which would form crystals faster based on the amount of sugar, salt they had to put into the boiling water to hit saturations point. This is a fun graphing project as well.
