Chemical A was a white power. It seemed to be room temperature and smelled a bit like flour. Chemical B was a golden liquid. It was room temperature and had no distinct odour. Oobleck was a whitish crème colour and gooey. Oobleck arose from a physical change because it changed state and no substances were produced. Ooblecks state is dependent on the amount of the two chemicals added. More of chemical A resulted it oobleck being a solid because you could roll it into a ball. More of chemical B changed it to a liquid because the oobleck flowed out of your hand. This lab helped me better understand how the particles make up different states of matter and the differences between solids, liquids, and gases.
