Classroom
Activities - Seeds
Science
Concepts:
- Seeds vary, e.g., in color, shape,
and form (monocotyledon, dicotyledon).
- Plants grow from seeds through a
life cycle.
- Offspring resemble parents.
PA Standards Addressed:
- 3.1.4.A Know the similarities and
differences of living things.
- 3.1.4.B Know that characteristics
are inherited and thus offspring closely
resemble their parents.
- 3.1.4.D Know that living things are
made up of parts that have specific
functions.
Materials:
Various
seeds including corn, maple tree seeds,
acorns, beans, raw (& roasted if you
want to compare living and dead) peanuts.
Activities:
- Observe and describe the external
characteristics of several seeds. Challenge
students to sort the seeds into categories
based on characteristics they observe.
Ask them to describe the characteristics
of the groups they have made. (See the
Seed Sorting worksheet.)
- Invite other students to observe others'
groupings and try to determine the category
names.
- Find individual differences in the
seeds. Observe that even within a type
of seed there are differences. (See
"Find your Peanut" worksheet.)
- Dissect the seeds. Identify which
seeds split easily into two and which
do not. Introduce the terms monocotyledon
and dicotyledon. (See "Seed Dissection"
worksheet.)
SEED SORTING WORKSHEET
Seed
Sorting
You
will need a packet of many types of seeds.
Work with your group to sort the seeds
on the tray into any groups you can think
of. For each group you make write down
how the seeds in that group go together.
When you have finished, show your groups
of seeds to other students. See if they
can guess the rule about how the seeds
go together.
