Standard 5/Elementary/Benchmark 2
Benchmark Question: How is energy distributed to living
things in an ecosystem?
Focus Question: What does an animal need to survive?
Students will work in small
groups to create a list of life requirements for a specific animal. Groups
will post lists and analyze them to find common life requirements. The
teacher will assign one role* in nature to each student. Each student will
create a nametag for his or her role. Standing in a circle, the teacher
will hold the end of a ball of string and start the web (see graphic below)
by tossing the ball of string to a student while stating the relationship
(e.g., a bear eats raspberries, the raspberry bush needs water, water
supplies cedar trees, etc.). The recipient will hold the string in one hand
and toss the ball of string to another student, stating the relationship
between their roles. Students will continue this exercise until the web is
complete. After the web is complete, the teacher will eliminate one role by
having a student tug on the string and drop it. Anyone feeling the tug must
also tug and subsequently also will be eliminated. At the end of the game,
students will discuss how they were affected and why.
*Possible roles: air, Sun,
water, soil, types of plants, types of animals.
