Thoughts??

SO I need some feedback on my DSS project!  I am about to start a new science unit on the states of matter (whenever we go back to school) and my plan was to take to pictures of the students in the science lab experimenting and to have them narrate their learning.  I am not sure if I will have enough time to do this so I was thinking maybe I should do my DSS as a way to introduce the unit. Sharing pictures of everyday objects and introduce the vocab for the unit.  Thoughts??
