§112.4. Science, Grade 2
 (6) Science concepts. The student knows that systems have
parts and are composed of organisms and objects. The student is
expected to:
 (C) observe and record the functions of plant parts
§111.14. Mathematics, Grade 2.
 (2.9) Measurement. The student directly compares the attributes
of length, area, weight/mass, and capacity, and uses comparative
language to solve problems and answer questions. The student
selects and uses nonstandard units to describe length, area,
capacity, and weight/mass. The student recognizes and uses
models that approximate standard units ( from both SI, also
known as metric, and customary systems) of length,
weight/mass, capacity, and time. The student is expected to:
 (A) identify concrete models that approximate standard units
of length and use them to measure length;
 (B) select a non-standard unit of measure such as square tiles
to determine the area of a two-dimensional surface
HOW LONG DO THEY LIVE?

The Life Cycle
The life cycle of a plant is how long it takes for a
plant to grow, give up its seeds, and die
 There are three types of life cycles for plants

Annual
 Perennial
 Biennial

ANNUAL
Completes it whole
life cycle within one
growing season
 Examples of annuals
include:

Tomatoes
 Marigolds
 Petunias

PERENNIAL
Plants that can live
for three or more
years
 The part of the plant
that is underground
can grow new stems
and leaves each
growing season
 Examples include:

Daisies
 Trees

BIENNIAL
These plants need two
growing seasons to
complete their life
cycle
 The first growing
season the plant
grows leaves and the
next season it grows
flowers
 Examples include:


Carrots
WHAT DO THEY NEED?
Plants need a few
things to be able to
grow.
 They need:

Sunlight
 Water
 And Soil (though some
plants do live in just
water!)

ACTIVITY!

What happens if plants don’t get sunlight?

For this activity we will have two identical plants
sitting in our classroom windowsill. We will give
each plant the same amount of water, but one plant
will be placed under a box to block all the sunlight.
The students will compare the plants’ growth over
the coming weeks.
PLANTS, WHAT ARE THEY GOOD FOR?

We use plants
everyday. All of our
fruits and veggies that
we eat are plants.
Also, plants help
make the are that we
breath. Plus plants
are fun to take care of,
which is always a good
thing.
ACTIVITY!

How much can a plant grow in a week?

For this activity we will have a young sunflower
plant. At the beginning of this activity we will how
tall the plant is using a ruler, we will also measure it
with non-standard forms of measurement such as
counting cubes and paper clips. We will let the plant
grow for a week and measure it again.
