II. Presentation of Lesson
A. Motivation
Show a PowerPoint presentation about the Story of a Buzzy the Bee.
“Today we are going to imagine a trip by Buzz, the bee, into the center of a flower. Now, Buzz
was a very busy little fellow and he did a lot to help out around the hive. One of his most important jobs was to
gather pollen from flowers to make honey.
One day as Buzz was flying along, he happened to notice one particularly bright flower – for those were always
his favorite kinds. He landed softly on a big, fluffy-looking leaf that was his favorite color – red! From there he
dove straight into the flower and noticed a big green stalk right in the center of the flower. All around it were
little stalks that waved in the breeze. They had funny little knobby things on their ends. Buzz, was really curious
what all these things were and decided to go ask his favorite uncle. As he left the flower, he sat on a green leaf
sticking out beside the flower and then took off into the big blue sky.
When Buzz got back to the hive, he eagerly asked his uncle what all these things were that he had observed.
Today, we are going to learn, along with Buzz, what these parts of the flower were and what they do.”
B. Processing/Linkage Questions:
- How many of you have ever looked really closely at the inside of a flower?
- Did any of you ever notice any of the parts that Buzz noticed as he gathered pollen?
- Well, how many of you have ever wondered what these parts of the flower do?
- What are some of your favorite fruits or vegetables that you like to eat – maybe they’re something you
and your family actually raise?
C. Lesson Proper
Let us now learn the parts of the flower.
- The first part we are going to look at is this pointy little leaf here at the base of the flower. This is called
the sepal. The sepal is important when the flower is young, because it helps protect the bud. Let’s all say
sepal together 3 times. And what does the sepal do for the flower? (Protects it when it is young.)
- Okay, as Buzz flew into the flower, does anyone know what the big, red fluffy looking leaf was that he
landed on? Petal. Very good! How many of you like this part of the flower best? The bright colors
attract pollinators like Buzz to them. The flower needs this to help it form new seeds. Ok, now who can
tell me what two parts we know now? (Sepal, petal.)
- Now we are going to move even farther into the flower, down to the middle where the big pistil sits. Can
anyone point to the pistil on the chart? ( Call on a student) The pistil is the female reproductive organ of
the flower. It is consist of the stigma, the style and the ovary.
- The stigma is the top part of the pistil that has a sticky surface to trap the pollen. (point on the chart)
The style joins the stigma and the ovary. Inside the ovary is the female sex cells which is called ovule.
This is a very important part of the flower because this is where the pollination occurs.
Pollination is the process of the little grains of pollen moving down the pistil where they form seeds.
The bulb part of the pistil is called the ovary (point on chart) becomes the fruit.
- Now let’s review a little. Can anyone tell me why flowers are so important?
- What happens in the pistil where the fruit begins to form?
- The last part we are going to talk about is the tall things with knobby on the end, these things are called
stamens – the male reproductive organ which consist of anther and the filament. The filament holds the
anther. The anther holds the pollen grains. This is where Buzz gathers the pollen he needs to make
honey. Now what holds the pollen? (anther)
- Pollens are yellow powdery substance used for making seeds.
- On the base of the flower it has Receptacle: The part of a flower stalk where the parts of the flower are
attached. (point to the chart) and Peduncle: The stalk of a flower.
Reinforcement: Present the parts of the flower using the real object.
D. Application
Activity
Group the students into 5 groups. Each group will be given an activity sheet to work on. They will
separate the different parts of the flower and paste each to its designated label. After 6 minutes, a
representative will present their work in front.
E. Concept Formation
Ask the students to formulate the science idea of the day by telling them what they have learned.
F. Integration of Value (Synthesis)
“ One of our school’s core values is Care for the environment. As a CICian, are you going to pick
flowers and play with it? What are the importance of flowers in the environment? What concrete
example or actions can you do to conserve our flowers?
IV. Evaluation
