Step 1: -Get 25 cm of clean magnesium ribbon
-A Ceramic Crucible
-A Bunson Burner
-A Ring Stand
Step 2: Weigh the clean empty crucible before starting the lab
Step 3: Weigh the crucible with the magnesium ribbon roled up inside of it
Step 4: To get the amounts needed for the data table, subtract the two weights to get the measurement of the magnesium strip before the heating process begins
Step 5: Place the crucible with the magnesium ribbon inside of it on the ring stand directly above the bunson burner, being sure it is stable and will not fall through when being heated
Step 6: Light the Bunson Burner... With Mr. Ludwig's HELP! :)
Step 7: In this next step white smoke is supposed to appear as the crucible and magnesium start to heat up. However in some cases it doesn't always work out this way as it didn't with Serena and I's lab. Our magnesium didn't smoke or change like it was supposed to. But hey that is the great thing about science you never know what your going to get when you try a lab out.
Step 8: As soon as the magnesium and crucible begin to smoke turn off the bunson burner and let the crucible cool for a bit, until it can be handled safely with one's hand.
Step 9: As soon as the magnesium and the crucible is easy to handle you wil notice that the ribbon has turned into a white powder, due to the heat of the bunson burner.
Step 10: Weigh the crucible and magnesium ( be sure to have been writing down these weights in your data chart)
Step 11: Now to find the weight of the magnesium substance left over after heating, take the after heating weight and subtract it from the weight of the empty crucible from the begining of the lab. This will give you the weight of the melted down substance of magnesium.
Step 12: Finally clean up your mess and clean out the crucible so the magnesium doesn't get burned and stick to the crucible and you are all done, and ready to annalyze your data!

Data Time!
Material Mass (g)
Empty Crucible 11.61
Crucible and Magnesium Ribbon 12.01 (Before Heating)
Magnesium Ribbon .60 Crucible and Magnesium Ribbon 12.17 (After Heating) Magnesium Substance .90 (After Heating)
Conclusion: With this lab we learned about another way of testing conductivity levels, along with many other things. Not to mention this substance had a low level of conductivity as its electrons didn't distribute a high energy. Along with that magnesium tends to weigh more after being heated. Not only does the weight change but its structure does as well. Overall, the process of this lab was one of low difficulty, but it is neat to see how each persons masses and product turned out. Afterall no one person's lab comes out the same as anothers!
