Answers

I cant find the answers, where do i get he answers????

hi mr.Buunsuuk

man, im so tired
every day physics class is so fun
arent you having a blast in this class?
the hell? stop farting mr.b :]
so.... yah im kinda dying in
physics haha i guess
im not gettting it, we
need a new teacher ahaha just kidding

anyone got the message? ;]

HELLO ALL!!! GUTEN MORGEN ES FREUT MICH, SIE KENNEN ZU LERNEN!!!!!!

Why I Do Not Like Physics

Sometimes i just want to be a sloth!! like the one from ice age!! just sit back and relax all day long!!

But yes physics is fun! you get to throw things around and blow things up, that is the reason why we study it!!!

But the physics we are doing involves more bookwork that playing with things that we could be designing, building, flying, crashing, exploding objects to test our theories.

OKay i dont know what i was writing about but yea here is the blog if you guys have questions or something post it here and anyone can comment and help you out yea all in all you guys have all the review sheets so happy camping if anything just just email me or call me alright see you guys in class

p.s. THE SLOTH BONES ARE COOL that thing is like 7 feet tall i was so tripped out
