Food chain game

• Each student will be assigned a role to play in
  simulation food chain. You will be either a
  grasshopper, a shrew or a hawk.
• The grasshoppers will be given a orange sheet
  paper. The shrews will be given a blue sheet of
  paper. The hawks will be given a green sheet of
  paper. You also be given a piece of double stick
  tape. You have to put the sheet of paper on your
  shirt. The sheet of paper MUST BE EASILY SEEN.

Grasshoppers

• Each grasshopper collects a small paper bag from
  me. Write your initials on it. This container
  will represent your stomach.
• When we get outside, I will spread the food.
  You can only pick up each piece of food ONE AT
  A TIMEIF YOU PICK UP MORE THAN ONE AT A TIMEYOU
  DIE
• The shrews and hawks watch their prey from the
  sidelines. You must stop collecting the food
  when I say.

Shrews

• After I tell the grasshoppers to stop collecting
  food, you may tag NOT TACKLE OR PUSH A
  GRASSHOPPER. You can only TAG ONE GRASSHOPPER AT
  A TIME. The grasshopper should take the bag of
  food and give it to you and go sit down.
• When I say stop hunting, you should stop hunting.

5
Hawks

• At this time, the hawks can start hunting for
  shrews. Shrews may hunt again for any
  grasshoppers who are still alive, following the
  same rules. When a shrew is tagged (NOT TACKLED
  OR PUSHED) the hawk takes the food bags and the
  shrew goes and to sit on the sidelines. The hawk
  can only TAG ONE SHREW AT A TIME. The hawk will
  stop hunting when I say stop.

6

• What to do when we get back in.do not eat food

7

• Animals who are still living at the end of the
  simulation should empty their food bags and count
  the number of food pieces they have and fill out
  the table.
• Animals that were consumed should find which
  animal has the bag with their initials on it and
  help to complete its tables

• In the environment in which these animals live, a
  pesticide was sprayed onto the crops to prevent
  damage by the grasshopper. The coffee candy
  represent plants that contained the pesticide.

10

• Grasshoppers still alive at the end of the
  simulation. if you have any coffee candyyou
  are now dead
• Shrews still alive at the end of the
  simulationif half or more of food is coffee
  candyyou too are dead
• The hawk with the highest number of food pieces
  lives at this time. However, because it has
  consumed pesticide, it will not have any baby
  hawks, because the egg shells it produces will be
  so thin.

11
Question

• Was the pesticide effective killing the
  grasshopper?
• Did the farmers want to kill the shrew and hawk?
  Would the farmers want these animals to live?
  Why or why not?

12
Assessment

• As a class, prepare a series of radio commercial
  on a specific animal and how pesticides affect
  animals. Each lab team should write a script of
  at least 5 minutes and act them out. The script
  should be on an animal of interest to them. The
  scripts should be entertaining, but factual. The
