molecular models & thrifting :)

love this!
i've been searching for molecular model practice that had good  picture & detail instruction.
all the resources i found gave vague detail-less & picture-less instructions on how to build the models,
leaving us to construct models using our own creative guesswork. (so frustrating) 
i bought this book a while back at our Friends of the Library used book store (my fave)for 50 cents.
the other day i pulled it out of my stack of books to browse & see if it was worth keeping.
i found exactly what i needed.
water molecules 
mickey-mouse molecule ;)
the girls actually had fun with this activity for a few hours.
a lithium model that K & muddled thru before using this book & without good instruction...but we did good ;)
