Welcome back!
1. Please water your quad with the dropper (1-2 drops of water).
2. Record your Week 6 height on the Amazing Plant Race.
3. Team Materials Manager- Get your team’s set of plants (Weeks 1-6).
Lesson 10: Looking at Flowers
What do you know about flowers?
Lesson 10: Looking at Flowers
Question: What are the parts of the Brassica
flower?
Study flower closely with your hand lens and
loupe. Draw an illustration of what you see.
Brassica Rapa Flower Parts
Sticky” Stigma
Anthers on top of stamens.
Powdery pollen are on the
anther.
Pollen sticks to the
stigma.

Brassica
Flowers
belongs to
the Crucifer
Family.
Why do you
think it is
called the
Crucifer
family?
Brassicas have many forms and uses
Brassicas are flowering plants widely used in the
human diet around the world.
• Vegetables of many types: roots, stems, leaves, buds,
flowers
• Condiments and pickles: mustard, wasabi, horseradish,
kimchee, sauerkraut.
• Animal feed and fodder
• Oilseed and meal, canola oil
Which crucifers have you tasted?
Some crucifer seeds
are crushed for their
oil. Others are good
food for people and
animals.
Extensions:
• Bring flower blossoms to class and have
your students take the flower pieces apart.
• Look for anthers, petals, stigma, etc.
• Tape in science notebook and label the
parts.

Observing Pods
Date
Lesson 12: Observing Pods
• Over a two to three week period, students
examine the development of the fertilized
pods.
• As the fertilized eggs grow into
seeds, the outside of the pistil
swells to become the seed pod
(or fruit) that encases several
seeds.
• Bring in other seed pods for the
students to “dissect” or open.
• Continue to measure – there is
very little upward growth, but
measuring will confirm this fact
for the students.

Brassica Model
Date
Lesson 13: Making a Brassica Model
• Students construct a model
of the Brassica plant.
• We will make a simple
version of the Brassica
model today.
• The example in the guide is
very complex, but good to
make as well!

14 Bee Model
Date
Lesson 14: Making a Bee Model
• Students construct a model of a bee.
• The stick puppet bee model is easy
and quick. The 3-D bee model
requires more skill and class time,
but engages students at a deeper
learning level.
• Use the play in lesson 14 with the
bee and flower models or have your
students create their own.
What
wrong
with
this
model?
All legs
should
be on
the
thorax.

15 Interpreting Graphs
Date
Lesson 15: Interpreting Graphs
• Students apply their science and math skills to
interpret graphs.
• View the graph of plant life cycles
• Question your students about the information on
the graph.
• For example: What is the title of the graph? How
many days does it take for Wisconsin Fast Plants to
develop seeds?
• Construct other graphs in class with student data.
Mary, Mary quite contrary, how does
your garden grow?
Draw and record your plants growth and development.
Make a
bar
graph:
Measure your
plants height and
record it on the
graph page.

16 Harvesting and Threshing the
Seed
Date
Lesson 16: Harvesting and Threshing Seeds
• Students harvest their seeds and compare
the number of seeds harvested with the
number planted.
Extension:
Scientific Method Experiment
How will different variables affect
the germination of rye grass and
wheat seeds?
Dry, moist with water, moist with
soda, moist with water under dark
cover

Date
Lesson 17: Post-Unit Assessment:
Sharing What We Know about Plant
Growth and Development
• Students discuss and reflect on what they
have learned.
• Display the first charts about plants.
• Ask the students to write their new facts
in their science notebook and share with
the group.
