    dissolving/recrystalizing 
    evaporating/condensing 
    freezing/melting 
    boiling 

    Mixed/separated
    bubbling

    E: change in shape and texture

    R1: Crushing chalk is a physical change because there was no new substance formed.  In the crushing of the chalk, only a change in size occurred.  

    R2: If there is only change in shape and texture, then crushing chalk would be a physical change and no new substance was formed. ]]>     2021-01-22 18:52:36 UTC https://padlet.com/LaurenGalvin143/zjpbo0om8xx9v67p/wish/1115451192     Reasoning statement for a CHEMICAL CHANGE LaurenGalvin143 https://padlet.com/LaurenGalvin143/zjpbo0om8xx9v67p/wish/1115507965 C: Burning sugar is a 
    E: color change, smell emitted

    R1: Burning sugar is a chemical change because the color changes and a smell was produced, therefore a new substance was formed.
