Materials
-
Collection of things that are alive such as living plants,
jars containing live insects or worms, any small animals
(fish, lizards, birds, mice), a person (student, teacher,
etc.), photographs of any plants or animals
- Collection
of objects that are not alive, such as rocks, dirt, coins, water,
a wind-up toy (to show that not all moving things are alive)
-
Two hula hoops, two large pieces of paper with circles
drawn on them or some other means of marking two spaces
-
2 labels: Alive, Not Alive
-
Magnifying glasses (optional)
The
teacher should collect all of the materials and create the
labels the day before. If having a collection for each group
is not feasible, place one collection on a table for children
to explore in small groups, that they can later discuss
as a class.

Procedure
- Show
the students an object that is a living thing. Ask the
students whether they think it is alive or not. How they
can tell? Ask the students to look at some of the other
students in the class and explain how they can tell that
the other students are alive. What are some of the things
the students do that their pets also do. Have the students
list some of the characteristics they have observed are
shared by all living things.
- Break the
class into small groups and give each group a collection of
objects, some alive and some not alive, that are common to their
experience of living in South Carolina, or photographs of some
of these objects. Try to use as many real tactile objects as
possible (plants, insects, pets, toys, coins, rocks, etc). Let
the children spend some time examining the materials. Encourage
the children to use the senses of touch, sight, hearing and
smell to observe the differences in the objects.
- After the
students have had a chance to examine the collection of objects,
ask them to sort the objects as to whether they are alive or
not alive at their tables. Encourage children to discuss why
they classified each object as alive or not alive.
- When
they have finished, place two hula-hoops, or other marking
objects, on the floor side by side. Inside each hula-hoop
place a label "alive" and "not alive".
- Ask
a volunteer from each group to bring an object from their
collection and place the object in the correct hula-hoop.
Have the student explain why they classified the object
as they did. What characteristics did they look for when
sorting the objects? The teacher will record the students’
responses on a chart.
- When
complete, have the children review their observations
and summarize the basic characteristics that determine
whether something is alive or not

Follow-up
Questions
- Have students
examine a drop of pond water under a microscope and then pose
the question, "Are there living things in the water?".
- Are
fossils living things? Have students use plaster of paris
to create imprints of their hands or of rubber animal
tracks (if available) to consider how fossils are the
imprints of living things, but are not actually living
things.
