As A Kid,

my bedroom walls were decorated with many cases of taxidermy fish, animals and birds,

 plus butterflies in cases, and also posters, but none as nice or informative as these, Matt Baker creates helpful visual guides that condense hundreds, and sometimes thousands, of years of history into streamlined flowcharts, the one above, Evolution and Classification of Life Poster, it is a 24x36" wall chart that is unique in that it serves as both a timeline of evolution and a guide to biological classification. Over 250 plant, animal, and microbe species are arranged according to the most up-to-date taxonomy (domain, kingdom, phylum, order, family, and genus) in a beautiful, easy to follow "tree of life" format. The chart focuses on species that are well-known to the average person so that one can discover interesting things such as the fact that green peppers are closely related to petunias or that dolphins are closely related to barnyard animals,

 I picked a few more at random, Timeline of World History, 

Roman Emperors Family Tree, now these I could really do with now,

especially this one, Greek Mythology Family Tree, as so many questions in the quiz shows we watch ask questions about the above! so for any plain walls in your kids bedrooms feed them a few of these visual learning treats, you never know they might be glad you did when they are on Who Wants To Be A Millionaire! all of these and more can be purchased at Matt Baker shop, Useful Charts.
