Lesson 10: Looking at FlowersQuestion: What are the parts of the Brassica flower?

Study flower closely with your hand lens and loupe. Draw an illustration of what you see.

Sticky” StigmaPollen sticks to the stigma.

PistilFemale part

6 Stamens Male parts

Anthers on top of stamens.Powdery pollen are on the anther.

Brassica Rapa Flower Parts

Petal

Sepal

Brassica Flowersbelongs to

the Crucifer Family.

Why do you think it is called the Crucifer family?

Extra

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.

11 Pollinating Flowers

Lesson 11: Pollinating Flowers

Bees and flowers need each other!

Pollinate flowers everyday there are blooms.

Let’s Pollinate the Flowers!!

Move to a new table when the song changes.

12 Observing Pods

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.

13 Brassica Model

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!

# Lesson Title Date14 Bee Model

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

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

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

17 Post Unit Assessment

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.

Dueling Flipchart Game!

1. The baby plant inside a seed is called a/an ___________________________.

2. A ______________________________ protects the inside of the seed.

3. _________________ are colorful and help insects see the flower to come to it.

4. The _________________is the sticky top of a pistil and it “catches” the pollen.

5. Leaves make their own food through the process called __________________.

6. The ________________ is the part of the plant that grows down into the earth and holds the plant in place.

7. __________________ is a powder-like dust that helps the flower make seeds.

8. The __________________ are special leaves that cover and protect the flower bud while it is growing.

9. The ___________________ hold pollen.

10. List one way pollination occurs. _____________________
