heating zinc oxide

 heating zinc oxide

aim: what change happens when we heat zinc oxide

equipment: Bunsen burner, heat mat, tripod, safety glasses, crucible, crucible holder, zinc oxide

results: Zinc Oxide is originally a white powder. When heated up, it turns yellow but does not decompose and when it is removed from the heat it gradually goes back to its original white color.

discussion: when heated the electrons and zinc move to the other levels making it change colour

Wade in the Water 

“The secret code in 'Wade in the water, God's gonna trouble the water' for the slaves trying to escape from slavery on the Underground Railroad, meant to be aware that one of the methods used by the slave masters to track runaway slaves down was to send their bloodhounds out to track down the slave,” 

this is a map of the slave triangle in the underground Railroad

If I were a metal element I’d like to be Mercury and my symbol is hg
My atomic number is 80 which means I have 80 protons in my nucleus and 80 electrons around my nucleus.
At room temperature (20C) I will be a liquid
My melting point (the temperature when I turn from solid to liquid) is -38.83 °C
My boiling point (the temperature when I change from liquid to gas) is 356.7 °C
I was first discovered by 1500 B.C. and We do not know who discovered it
I am found in nature is usually found in ores such as cinnabar, livingstonite, and corderoite. Most mercury today is produced from the mining of cinnabar, a bright red ore.
My uses to humans are: to make thermometers, barometers and other scientific instruments tips switches with Mercury
Some interesting things about me are: I can be could make liquid mirrors and it's a liquid metal
