Physical and Chemical Changes Lab

CH, CH, CH CH CH, CH CH CH CH, CH CH......Honestly, I have lit a match before!!!!
 
Great work today!!!  No fire alarm....huge sigh of relief.  I think my favorite part was watching you smell the vinegar/ chalk reaction (insert evil laugh here :)  Also, I loved the extra experiments you thought to try and thoroughly appreciate all of you getting prior permission before your attempt. 
 
Remember the take home message...Chemical changes form a new substance, with new properties.  In physical changes, only the form of the substance changes. 
 

Observing the candle
 
Chalk and Vinegar
Heating the sucrose
 
Best reaction ever!!!

    Hanna,

    That smelt horrible with a capital H! I can't believe that Sammy and I would have thought vinegar and chalk mixed together would smell good.

    Nicole,
    The vinegar and chalk smelt bad how could you say that Hanna. :) I liked lighting the matches! That was so fun I don't even know why. I am glad I got to learn how and can't wait to see the pictures of Riley and I lighting them for the first time. LOL :) Can't wait for tomorrow. Any more experiments planed?

    This is my favorite lab because I got to light a match for my very first time!! If I could change this lab I would roast a marshmallow and then eat it to see the difference:) I would also light a match a couple more times. This was an awesome lab!!!!!
