Learning Outcomes
Students will:
- describe food webs involving
humans.
- understand that a food web is made
up of many food chains that are linked.
Activity
- Set up a bulletin board display entitled
"Food Webs for Humans". Position a
circle representing the Sun to the side.
- Write the following names of organisms on
separate small index cards:
| Grass |
Moose |
Human |
Corn |
Chicken |
| Duck |
Hay |
Grasshopper |
Cow |
Trout |
| Shark |
Seal |
Water Plants |
Twigs |
Rabbit |
| Berries |
Bear |
Salmon |
Carrot |
Mosquito |
| Worm |
Pig |
Codfish |
Sheep |
Deer |
- Give each student an index card.
- Inform the students that they have to listen to
the instructions that you are going to give them.
Tell them that at some point they will use thumb
tacks to attach their index cards to the bulletin
board, draw arrows to certain locations, and
return to their seats.
- Directions for the students:
1. The Sun
provides energy for the plants. If your organism
is a type of plant, attach the index card to the
bulletin board, draw arrows from the Sun to your
plant, and return to your seat.
2. If your organism eats plants, attach your
index card to the bulletin board, draw an arrow
from the plant to your organism, and return to
your seat.
3. If your organism eats any of those already
in the display, attach your index card to the
display and draw arrows from the others to your
organism and return to your seat.
- Continue with this procedure until all students
have attached their index cards and then have a
discussion about the completed food web to see
that they understand the food chain sequences.
