State Change Lab

 

 

Today we did a lab where we observed chemical and physical changes when chemicals mix.

8. Some chemical changes I saw in the bag were that the substance became bubbly a warm, not like it was in its previous state (blue liquid+white powder+little balls of white). Some physical changes I noticed were the form (from solid and liquid to bubbly liquid) and colours (white and blue to yellow)

  1. Hi Nour,
    Really good observations! I loved how you compared the white powder to snow and I also liked the descriptive language you used, like ‘bubbly’. One thing I would add would be the weights of all the chemicals separately. Other than that, very good!

    • Thank you so much! Lol I didn’t realize that we could measure them, I wasn’t paying attention to the weight measuring thing.
