The object of this game is to identify a variety of plastic
safety items and match them to the appropriate person. By
doing so, children will learn that a variety of safety devices
are all made from plastics. For example, the safety helmet
made from polystyrene and fiberglass belongs on the in-line
skater.
Parents and teachers: While playing this activity, encourage
children to think of additional plastic objects that help
to keep them safe at home, school, and play. This will help
children prepare for the quiz at the end of the activity.
Plastics in your home
This activity is similar to the safety activity, except this
time we take a look at how plastics help play a key role in
many household products and objects. By placing items in the
house correctly, children learn how plastics improve our daily
lives and are used for many objects in our homes. For example,
plastic sandwich bags that keep food fresh and prevent contamination
belong in the kitchen.
Parents and teachers: While doing this activity, encourage children
to think of additional plastic household objects that play a
role in their everyday lives. This will help children prepare
for the quiz at the end of the activity.
Materials
A variety of polymers that can be categorized into four groups:
hard, soft, sticky, and malleable. (These four characteristics
match the song and finger puppets, but other characteristics
could be used as well, such as rough and smooth.)
Procedure
Review the atomic structure of polymers - e.g., atoms, molecules,
polymer chains.
Display a variety of polymers on a table in view of the class.
Discuss "same" and "different" aspects
of the items.
As a large group or in small groups, list all descriptive
words on the chalkboard, or on a data sheet. Through guided
discussion, decide on the major categories: hard, soft, sticky,
and malleable (or other characteristics you decide).
Evaluation
Students are able to classify polymer examples according to
the characteristics chosen (Soft, hard, sticky, and malleable).
Students are able to choose characteristics of polymers and
sort examples accordingly.
Suggested Materials
Fiber fill, picnic cooler, play dough®, legos®, straws,
credit card, vacuum bottles, plastic table ware, nylon hose,
balloon, baggies®, food containers, epoxy glue, toothbrush,
comb, carpet, silly putty®.
