Today in Science we had to do a experiment with Zinc Oxide. First we had to setup our equipment, then we had to to get the zinc oxide and put it in the Crucible using a spatchular. Next we had to turn on the head, then thats when it changed from colour to colour. Here is the experiment.
Aim: What changes happens when we heat Zinc Oxide.
Equipment:
Bunsen Burner.
Heat Mat
Tripod
Safety Glasses
Crucible
Crucible Holder
Zinc Oxide
Spatchular
Method:
1. Get all of the equipment and set it all up
2. Get the zinc oxide and put it into the crucible with a spatchular ready to heat it up.
3. Turn on the heat and light the bunsen burner with a lighter.
4. Wait to see what happens to the zinc oxide.
5. Have fun!!!
Results: When I heated the zinc oxide the powder changed from the colour white to yellow but when The heated turned off the colour changed from yellow back to white.
Discussion: When the zinc oxide is heated, the electrons in zinc move to other levels making it change colour. When it is heated the oxygen goes away but when it is not heated the oxygen attracts back to the zinc, which makes the zinc move to other levels.
