Cooper's been coming home from school with "research projects."  I get the impression, though I'm not entirely sure, that he "reads" a book and then draws a picture about that subject.  (I've provided translations in case you're not up-to-speed on interpreting preschool cursive and spelling.)
"the africn elephants r coowl" = The African elephants are cool. 
"sum spidrs or poysnis" = Some spiders are poisonous. 
"sharks or big" = Sharks are big. 
"deep insid dee rf hids lovu" = Deep inside the Earth hides lava. 
"shorcs eet fish" = Sharks eat fish. 
"wals spra wodr" = Whales spray water. 
"spas is coowl" = Space is cool.
