Matter

 The  junk  materials  lab was  a really  cool  was  to  help  us  think about  matter and  classification. I liked this activity  because  something  that  sounded  so easy  became  hard. The  first  classification   of  composure was  easy to  do   but  then  when  it   came  toe  the  usage classification  it  was  hard  because  some of the  materials  were  thing  that are  not  commonly used or  didn't  exactly  fit  into  the  groups.I  also  liked the  part  with  the  baking soda  because   in  the  beginning  we  knew  exactly  what  the  materials were but  after  adding water  to the baking soda  it  was hard to  classify  what  type of  matter it  was  even though we  know  the  definitions  of  what each type of matter is. This  made  me  think  about  how  hard  a  concept  like this  would be for  elementary children.  When  looking  up the definitions  for children  some  of the  definitions were so  complex that   some  adults might  not  understand.
