Lesson 5: How Does Your Plant Grow?
(Day 5, 6, 7, or 8)
At this stage of the growing cycle
(approximately Day 5, 6, or 7—possibly 8),
the plants have grown tall enough for
students to measure and record their
height in centimeters on a graph. This is an
opportunity for students to apply graphing
skills to the experiences they are having
growing plants.
Materials List
For each student:
 Student notebook
 1 quad of plants
 1 sheet of centimeter
graph paper (see
Appendix F of teacher’s
guide)
 1 strip of paper precut to
1 centimeter wide (see
Appendix F of teacher’s
guide)
 1 pair of scissors
For the class:

1 bag of 500 snap-together
centimeter cubes

Glue

Crayons
Students complete this weekly.
Same day every week.
Wisconsin Fast Plants Growth Graph
Glue the Wisconsin Fast Plants Growth
Graph into your notebooks. (TH-7)
Choose one plant to measure for the rest
of this unit.
Move your name label to that cell of your
quad to mark the plant you have chosen.
Write the age of the plant in the
appropriate place and measure.
Measuring with paper strips…
Mark the height of the
plant by drawing a line on
the strip.
Fill in the squares below
that line.
Double-check by holding
the paper up against the
plant again.
Cut off the darkened
squares and above the
correct day number and
glue it in place.
Measuring with centimeter cubes…
Fit the cubes together so you can
measure your plant to the nearest
centimeter. The bottom of the cube must
rest upon either the potting mix or the rim
of the quad. Always rest the cubes or
paper strip on the same place when
measuring your plant.
Lay the cubes on the graph
above the correct day number
and mark the height of the
column.
Darken in the bar graph to that
height.
In our training:
Measure one plant in each quad.

Lesson 6: Observing Leaves and
Buds
Overview
In addition to growing in height, plants also
develop leaves and flower buds. In this
lesson, students will observe the first true
leaves and the buds on their Brassica plants
and record their observations in both words
and pictures. These developments will take
place on approximately Day 7, 8, or 9.
Observe your quad of plants with a hand
lens.
Look for the following:
Differences between the seed leaves and
the true leaves
Number of both kinds of leaves
Color, size, shape, and number of buds
Draw and label the plant in your
Observation Sheet. Your drawing
should show the following:
the age of your plant in days
the differences between the two kinds of
leaves
the buds
the right number of leaves and buds
How old are the plants today?
Our plants have changed a lot
since Day 1. What was the first
stage of the plant’s life cycle?
Life Cycle Cards
At about 24 hours after planting, the
embryonic root emerges.
After about 28 hours, the seedling emerges
from the potting mix. The seed coat is split and
the white cotyledons or seed leaves are visible.
During Day 2 and 3, both the root system
and the cotyledons, which are now green,
continue to grow.
On Day 4 or 5, the first true leaves appear at
the growing tip of the plant, between the
seed leaves.
From Days 4 through 7, the true leaves
continue to emerge and grow at a
remarkably rapid pace.
By Day 8 or 9, the yellow-green flower buds
appear in a tight cluster.
What do you think will happen
to the plants next?
Write your predictions in your
notebook.

Lesson 7: Growth Spurt
(Day 9)
Question: What is a growth spurt?
Growth Graph
Days 9 – 13 are the growth spurt days
and dramatic changes happens. Record
daily on Growth Spurt Chart.
After day 18 there is very little growth in
height. The plant is busy producing
buds, flowers, and seeds.
Measure at least once a week to confirm
that growth has slowed or stopped.
Record this on the Growth Graph.
