We made crystals in earth science and I will tell you about it.They are white with pipe cleaners in it witch makes it the color the pipe cleaner.They are kinda sharp and fall off the pipe easily.We talked about the minerals and what it had.The other thing we did was shrinky-dinks with Dr. Adams. So what you do is get a piece of spastic. Then you draw on it and put it in the microwave. Last it shrinks and it becomes a ordinates.I did a cowboys star on it.
