One of the reasons I adore my physical science class is that they love the posters I have hanging up in my classroom. Decorating my classroom makes my heart happy, and the fact that I have students who take the time to show appreciation for my hard work just makes my heart even happier. A couple of weeks ago, my students insisted that I needed to make a mole poster with Avogadro's number. Of course, I'm pretty sure that 6.02 x 10^23 was stuck in their heads long before I got the poster on the wall because we have done SO MANY stoichiometry problems!
The mole clipart is from www.supercoloring.com.
I printed this poster on 11" x 17" cardstock (affiliate link). This stuff is my go-to to making quick posters for my classroom! It's the biggest paper size that my school's copy machine handles.
Here's a couple of pictures of the poster hanging up in my room.
