Materials
We have included several examples of household items that can be used to represent
adaptations in living things. After each listed item we have included ideas
for specific adaptations that each item may represent. We are sure that you
can think of many other ways these household items, and others, can be used
to represent specific adaptations.
- tongs (to represent a body part that pinches, i.e. crab claws or pincers)
- tweezers (to represent a body part that grasps tiny objects, i.e. birds
with finely pointed beaks)
- scuba fins (to represent a body part that assists in movement in water,
i.e. the webbed feet of river otters, turtles, alligators and many aquatic
birds)
- large-toothed hair clip (to represent a body part that snaps shut or is
filled with teeth, i.e. the jaws of an alligator or gar)
- clothes pin (to represent a body part that grasps objects, i.e. birds with
beaks)
- hard hat (to represent a body part that provides a protective covering,
i.e. the shells of turtles, the exoskeletons of crabs and insects, the shells
of snails)
- bicycle helmet (to represent a body part that provides a protective covering,
i.e. the shells of turtles, the exoskeletons of crabs and insects, the shells
of snails)
- piece of leather (to represent a body part that provides a protective covering,
i.e. thick shark skin)
- a bathroom plunger (to represent a body part that attaches to something
by suction, i.e. the suction cups on an octopus' arm and the tube feet on
sea urchins, sea stars and sea cucumbers)
- piece of shower mat (to represent a body part that attaches to something
by suction, i.e. the suction cups on an octopus' arm and the tube feet on
sea urchins, sea stars and sea cucumbers)

Procedures
Part I
- Ask students how they
prepare for a day at the beach, cold weather, or eating pizza. Do they wear
winter coats to the beach, shorts during cold weather or eat with their toes?
Discuss responses and explain that students adapt to their environment.
- Ask a student to wear
a coat that you have in the classroom. Discuss how it is used for protection/survival.
Introduce the term adaptation and explain how organisms have adaptations that
aid in survival.
- Show the class one household
item and ask the students, "What does this item do?" and "How is this item
useful to the people living in your home?". Record their responses on the
board.
- Ask students if they
can think of an animal or plant body part (an adaptation) that is used to
do something similar to that of the household item. Encourage students to
use similes during this activity. They often help students to link a new concept
to something that they already know or to something familiar. A few examples
are provided below: The suction cups on the tube feet of sea urchins are like
a bathroom plunger. Both things use suction to grab hold of other things.
The fur on a river otter is like a winter coat. Both things are used for warmth.
The shell of a turtle is like a hard hat. Both things are used to protect
something soft underneath.
- Divide the class into
groups of five. Give each group a plastic bag/storage container containing
five different household items.
- Explain that students
should decide how the items are useful to humans and record their ideas. They
should discuss their ideas as a group.
- In their groups, students
should discuss how the household items can be compared to adaptations used
by animals or plants. Students should use similes to relate each household
item to a plant or animal adaptation.
- Students should record
their similes. Discuss the responses.
Part II
- Review the term adaptation.
Show the students an item that hasn't yet been discussed. Ask them to explain
how the object depicts an adaptation in an animal or plant.
- Divide students into
teams of five. Give each group of students an Adaptations Observation
Record. Have the
students look at the pictures and decide what adaptation(s) each animal or plant
has. They should record their observations on their worksheets.
- Next, discuss the habitat
of several of the organisms. Ask students to explain how the adaptations allow
it to live in its habitat.
