Ah, the start of a new unit. You can almost feel the excitement in the air. Or maybe that is the smell of mothballs from this week's density roundup lab. I can't tell, myself, being colorblind.
This unit is on solids, liquids, and gases. What are their main differences and what are their similarities? First, they are all just different phases or states of the same substance. For water, the substance we know the best for these three states, it is easy to tell differences in volume and shape.
I also talked about the fourth (actually the fifth) state of matter: plasmas. The first state of matter, from least amount of thermal energy on up, is Bose Einstein Condensates. Have fun reading about them.
