Hawks and rabbits
and grass oh my!
Questions to Ponder
How do organisms interact
with each other in an
environment?
What should an ideal
population look like?
Rules for Relationships
(it’s all about relationships!)

offspring of the same species.
Hawks eat only rabbits. Rabbits eat only grass.
It is assumed that grasses get all the nourishment
they need (water, sun,etc).
Animals – hawks and rabbits – must eat at least every
other turn to avoid death by starvation (keep track).
Do not tell anyone you “pair up” with what you are—
or I beat you!
I will take totals of what organisms are left after each
turn. Put you head down and raise your hand when I
ask about each organism.
Data Collection
Record group data on a sheet of paper
of each generation and the number of
organisms in that generation.
After 6 generations have been
recorded, graph your data on a sheet of
graph paper and LABEL all parts of your
graph!
Interpret and analyze data and graph.
Explain trends, and future possibilities.

Questions for Conclusion: Write your answers in complete
sentences on a sheet of paper; label it “H-R-G conclusion.”
1.
What would the community be like in 10 generations?
2.
What would happen if another small mammal was introduced to the area
at the beginning of this activity?
3.
What would have happened if we did start with equal numbers of hawks,
rabbits and grass?
4.
What should the population numbers be like in a successful community?
5.
What might happen if some of the rabbits inherited the characteristic of
camouflage fur? What would happen to those rabbits that did not?
6.
What might happen to this population if
Elmer Fudd hunts frequently in this area?
Explain your answer.
