| Title: Food
Web Follies |
| Subject: Science
|
| Grade Level: 7
|
| Overview:
|
| This lesson helps students develop a better understanding of how
the energy flows in a food web. |
| Approximate
Duration: 1 period |
Content Standards:
- Life Science
The students will become aware of the characteristics and life
cycles of organisms and understand their relationships to each other
and to their environment.
- Science and the Environment
In learning environmental science, students will develop an
appreciation of the natural environment, learn the importance of
environmental quality, and acquire a sense of stewardship. As
consumers and citizens, they will be able to recognize how our
personal, professional, and political actions affect the natural
world.

Benchmarks:
- LS-M-A4
describing the basic processes of photosynthesis and
respiration and their importance to life; (1,4,5)
- LS-M-C2
modeling and interpreting food chains and food webs;
(1,2,3,4)
- LS-M-C3
investigating major ecosystems and recognizing physical
properties and organisms within each; (1,2,3,4,5)
- LS-M-C4
explaining the interaction and interdependence of nonliving and
living components within ecosystems. (1,2,3,4,5)
- SE-M-A1
demonstrating knowledge that an ecosystem includes living and
nonliving factors and that humans are an integral part of
ecosystems; (1,2,3,4,5)
- SE-M-A2
demonstrating an understanding of how carrying capacity and
limiting factors affect plant and animal populations; (1,3,4,5)
- SE-M-A5
tracing the flow of energy through an ecosystem and
demonstrating a knowledge of the roles of producers, consumers, and
decomposers in the ecosystem; (1,2,3,4,5)
- SE-E-A6
distinguishing between renewable and nonrenewable resources and
understanding that nonrenewable natural resources are not
replenished through the natural cycles and thus are strictly limited
in quantity; (1,2,3,4,5)

Educational Technology Standards:
- Use multimedia tools and desktop publishing to develop and
present computer-generated projects for directed and independent
learning activities.

Background
Information:
This activity should follow a discussion of producers, consumers,
decomposers, food webs and food chains. This activity is also a hands
on approach to creating food webs. |
Lesson
Procedures:
1. Review with students terms relative to activity: producer,
consumer, decomposer, food web, food chain, photosynthesis, energy
transfer
2. Pass out worksheet. Explain to students they will cut out pictures,
paste them in order on a food web, and label each correctly.
3. Students will utilize the computer/printer in the classroom to type
names of animals and print them out for cutting/pasting on the food
web.
4. Teacher will pass out scissors, glue sticks, and construction paper
to students.
5. Teacher will assist students if they are unfamiliar with where an
animal fits into the given food web.
6. After students finish completing food web, they are to draw a sun.
Explain that the sun is the most important energy source in any food
web.
7. When students turn in their food web, they are to write a paragraph
explaining the role photosynthesis plays in food webs. |
Assessment
Procedures:
Students will be graded on the finished product turned in on the above
rubric scale. Paragraphs will also be graded. |
Accommodations/Modifications:
Students needing extra help will be given a food web with words
already placed on the page. The student will only have to cut and
paste the pictures.
