|| Our copper is set next to the beaker with a petri dish on the top. Spencer and I are very excited to be doing Chemistry because Chemistry is awesome and we like setting things on fire. ||

It started out being light blue, then turning different shades of blue until eventually it reached a dark gray color, also becoming a thicker opaque solution. ||

|| First of all, please enjoy this picture of Spencer and I enjoying Chemistry class and a slice of pizza.

On the fourth and most glamorous day, we looked at the copper again. The copper had settled to the bottom of the beaker and looked like dust. We scraped the left over pieces of copper off the side. We added some water to the copper and stirred it around. || || Today we decanted the copper. The copper residue had sunk to the bottom of the beaker by now, leaving the acid on the top. So we poured out the acid using a stirring rod (because of the cohesive and adhesive property of water it sticks to things), and poured it out into the drain. Then we poured in 200 mL of new water. We lost some copper when pouring out the old acid solution, although we don't know exactly how much. || || Day 6! Spencer decanted the copper solution, then added 30 mL of hydrochloric acid (12 M) into the copper. It reacted immediately; it went from black (with clear specks of copper), to a bright green mixture, to a clear turquoise shade of blue with no visible specks of copper. || ||  ||
