Standard Indicator Grade 4Tracie Ambrose
1
Standard 4.4.3Observe and describe that organisms interact with
one another in various ways, such as providing food, pollination
and seed dispersal.
2
DefinitionsOrganismany living thing.PollinationThe process by
which plant pollen is transferred from the male reproductive organs
to the female reproductive organs to form seeds.Seed dispersalthe
movement of seeds from the original plant to another location.

ObjectivesAfter instruction, student will name the parts of the
food web.After instruction, student will describe the conditions
that will occur if any part of the food web is disturbed.After
instruction, student will identify the different methods by which
plants are reproduced.After instruction, student will create a
correct model of an ecosystem.

Lesson PlanMaterials Needed: ball of yarn, pictures of different
animals, plants, grasses, and people.Have students form a circle.
Give each student a picture. Give the ball of yarn to a student
with a plant. Have that student gently toss the ball to another
student who has an animal that uses that plant. That student holds
his end and tosses the yarn to another student who holds a picture
of an animal that consumes his animal.When that web is complete,
start another ball of yarn in a different color. Give to a student
who is not holding a piece of yarn. Repeat the above steps until
that ball of yarn has run its course. Give a third ball of yarn and
repeat the steps.By this time there should be a real mess of
tangled, colored threads.

Lesson Plan Page 2Have students discuss with each other how the
web looks to them. Ask them to describe how each color of the web
connects the consumers within that web. Have them discuss how the
three different colors interconnect. Have them discuss how the
different organisms in the web use others. For example, the horse
eats grasses and the human uses the horse for planting or the cow
eats grass and the human consumes milk products, uses the hide,
eats beef, etc.Finally, have students drop their string one at a
time and take out the users that are affected.Give students time to
think about how the web is affected by the loss of users. Give them
an opportunity to discuss their thoughts.
6
Lesson Plan Cont.Draw and label a food web.
For the second part of this lesson, talk about how different
plants are reproduced via this web.Give students different seeds.
Have them complete a chart about the different seeds. Chart on next
slide.
7
Seed ChartWhat is the seed?What are its characteristicsHow do
you think it moves from one place to another.
8
Web quest and SummaryGo to the web site below and watch the
video of how seeds are dispersed.In your science journal, answer
the following
questions.http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/dispersal.htmWhat
do seeds need in order to disperse?Why do seeds need to
disperse?How do humans help of hurt seed dispersal?What is your
favorite way for seeds to disperse? Why?
9
Final ProjectFinally, ask students how the animal web and the
seed dispersal relate to each other. Allow group discussion.Give
groups (3 students per group) a shoe box and supplies. Have groups
construct ecosystems including the plants, animals, and seeds that
work together to form a web. Allow students several days for this
project.
10
AssessmentStudents will be assessed on their participation in
the group web.Assessment will also be based on the how the student
uses details to describe seeds and seed dispersal and on the animal
web.

Interdisciplinary LinksSocial studiesthe principles of this
lesson can be applied to the consumption of natural resources,
cultures, and economics (buy and selling).Artmany of the projects
used art to help students visualize the web.P.E.the principles of
this lesson can be used to relate the consumption of vitamins and
minerals to the use of energy.Maththe steps to solving math
problems can be related to the parts of the web.Literacy
ArtsStudents use journaling and writing to describe their
web.Technologystudents use technology to research seed
dispersal.
