when we got to class we settled after picking up a note card and new unit packet then mrs stein passed back our grade reports. then we talked about the science contest! if you participate you can get extra credit but don't ask how much because mrs. stein hasn't decided. pretty much its a contest on how well you answer a few questions relating to science on april 14th. only one period that you sign up for to go to the advent is when you will be competing. you create a team of four people and freshman are more valuable because we haven't taken as many science classes as upperclassmen (yay us!) if you want more details read the website: https://webmail.glenbrook225.org/owa/redir.aspx?C=caf88c51729148829a2f662a0033e31e&URL=http%3a%2f%2fwww.glenbrook225.org%2fsouth%2fdepartments%2fscience%2fPages%2fhome.aspx. after we talked about getting new seats when people return from spring break. also we filled out a post card about how comfortable we felt with dissection and if we wanted to do a lot of dissecting or not and who we worked well with. these will help mrs. stein determine new lab groups. new we talked about what we already know about our new unit!
