Sir and Madame Biologist
Do. . .
- Choose two students (girl
and boy) to be Sir and Madame Biologists- these students will record
the numbers of cranes who survive . Have them make a prediction about
how many cranes can survive in this wet meadow. Have the students make
observations and record number of cranes.
- Divide the rest of the students
into crane groups of five. Have each team line up at on the border of
the playing field (relay style).
- Once in groups of five-
Describe the rules of being a crane.
- They collect food: 1 piece
of food at a time and take back to their family of cranes.
- Then the next person can
go and get one piece of food.
- Sir and Madame Biologist
will make observations to try and answer the following questions
- How many types of food
do the cranes collect?
- What foods do the cranes
seem to collect the most of?
- What foods are most
abundant?
- Once the rules are explained
start the collection by saying GO.
- Have the biologists
report on what they observed? Three types of food- red, white, blue.
More white chips than other chips and they are clustered together
in areas (like fields).
Explain. . .
- The chips represented the
following foods that cranes eat:
- White chips are GRAIN worth
3 points (the most abundant in farmer's fields)
- Red chips are SNAILS worth
5 points
- Blue chips are FROGS worth
10 points
- Have each team calculate
their points.
- In order for the team of
cranes to survive they need to have 100 points. To do this have the
biologists calculate the number of cranes surviving and then determine
the carrying capacity of a wetland meadow
Discuss. . .
- How many of the cranes survived?
- What was the carry capacity
for this crane population?
- Was this what you predicted?
- How was this game we played
"Field Research"?
