UNIT 2
FOOD CHAINS/WEBS AND DIGESTION
4-PAS/SAB
MAKE A FOOD CHAIN/WEB
  A food chain is a way to show food relationships between plants and animals
or how energy passes from producers to consumers.
  Every student scientists was either the sun, a plant, an animal, bacteria or a nutrient.
  They had to figure out where the chain starts and ends.
  They did it a few times until a food web was made!
A food web is the interrelationships between several food chains.
 Great job scientists!!

4Tho/Ell
Dissects an Owl Pellet
  To get the concept of a food chain, our student scientists
will dissect and investigate an owl pellet.
  They worked in pairs to separate the bones from the fur.
  They found a lot of bones and some skulls.
  As they found bones they cleaned them off and put them in a bag.
  Can you figure out what this owl ate?
  Once all the bones are separated they will glue them
on a piece of paper and figure out what their owl ate.  Mr. Thompson took the time to name a few of the bones!

4 - Wei & 4 - Pas/Sab Dissect Owl Pellets   Mrs. Weiner's student scientists also worked in pairs to dissect their owl pellets.   They worked very hard to find as many bones as the could.   Some seperated the fur while their partner cleaned the bones.   It is very interesting to see how many bones are in one pellet.   It will take a couple of lab days to finish the job!  Some big bones have have been found.   Mr. Pastore/ Mrs. Class starting gluing their bones on black paper.
  Now they can see the skeleton of the owl's prey!!
  So many bones, so little time!!
