lesson plan
Warming Up : (5m)
open question) What do living things need to)
survive? Challenge the students to name one living thing
that doesn't need them. People need these things, too.
Presentation: (25)
a. In groups, have students brainstorm possible food
chains. Each chain should have at least four links
Brighter students can be challenged to add a pollutant step
in theirs. ... a sample worksheet page of food chains is
given in the About Woodsy Owl Teacher Guide packet
b. Each group puts together a food chain of their own.
Every member of the group draws a picture to represent their
part of the chain.
c. Once completed, each group mixes up the chain
paperclips it together in mixed up order, then hands it to
the next group beside them. Every group has a "new" food
chain, and reassembles it into the correct order. " The
owner group" can correct the finished order.
Evaluation:
What do you notice about these relationships?
(interpretive question) (3m)
How could we account for the
fact that in some areas, the top of the food chain dies
the middle? example: all the coyotes that normally eat
rabbits and mice disappear.
(interpretive question) (5m)
Do any species on earth seem to have
influencing on their food chain or environment ?
(summary question) (5m)
Could anyone suggest one word or phrase that tells about the relationship between ?plants, animals, and man
