Crystal & Minerals Blog
In the Crystal Growth Lab, we made a experiment based on letting the crystal grow and wait for the time to let the crystal grow. We did salt and sugar as our experimental variable. It turn out the result is very cool, the glass was full of crystal. If we have chance to do it again, we would like to have more options to choose as our experimental variable to test. In this section I learned luster, color, streak, hardness, cleavage, fracture, composition as vocabulary.
