Pre-Viewing Activities
1. To introduce the lesson, teacher will read the book Miss Rumphius. Miss Rumphius is the story of a little girl who promised her grandfather that when she was grown she would do two things: 1) visit faraway places 2) live beside the sea.
Her grandfather told her she must do one more thing. He told her she must make the world more beautiful. Later in her life she had fulfilled the first two promises and was almost perfectly happy until she realized she had not yet made the world more beautiful. After much time and thought she discovered that her secret way of making the world more beautiful was scatter lupine seeds everywhere she went.

2. Teacher discusses with student the reason that Miss Rumphius decided to spread seeds everywhere she went. (Conduct a discussion on the beauty that flowers add to their lives). Show any pictures of flowers that are available.

3. Teacher then asks, "Is being pretty the most important job for a flower?" Students and Teacher brainstorm ways in which we use or enjoy flowers. Record their responses in their "Flower Power" Science Booklet.
Focus Viewing
Explain to the students that a person who studies flowers is called a Botanist. Tell them that during today's special flower power lesson they are Botanists because they will be investigating "Flower Power". Pass out flower power booklets. Explain to the students that they will be recording their findings in their Flower Power Learning Log. This booklet will help them to remember what they learn. Explain that in the book Miss Rumphius, the flower's job was to make the world a beautiful place.

Let's watch and see if we can find if we really know what a
flower's most important responsibility is. Tell the student that what they are about to see is a woman named Kate who lives in the country. She is writing a book about plants. With her is a boy who lives in the city. He has come to stay with Kate for a vacation.

Viewing Activities
1. START the video when the boy says, "I like taking pictures of flowers, but did you know a flower has a more important job to do that looking pretty. "Take a Look, Flowers and Seeds.

PLAY the video tape to the part where Kate says, "Flowers work hardest when they are no longer pretty. That is when it makes seeds. PAUSE.

2. Teacher then asks again the question," Is a plant's most important job to be pretty? Students record in their booklet:
A plant's most important job is to make seeds.

3. Teacher then informs the students that an important part of being a Botanists is to know the special names for each part of the flower. Tell them to listen closely and be ready to identify so they will be able to record the information correctly.

4. PAUSE THE TAPE again after the boy explains the pollen is the part that makes you sneeze. Again return to the booklet. Draw a flower and label the parts of the flower.


5. Pass out an index card, a real flower and a section of wide tape clear tape for each student. Petunias, tulips or violets are great. (Late summer/early fall is a great time for this lesson when petunias are quite plentiful).
Have students tear their flowers in half and tape it on the index card. (The clear tape goes on top of the flower. This preserves them for years.) Have the students label the parts of flower.

The teacher asks if anyone knows what the pollen does in producing new seeds. RESUME THE TAPE. Until Kate has finished explaining the reproduction part of a flower. She then pauses the tape and the class records in their own words the process in their booklet.

7. Before resuming the tape, ask the students if any of them know how the pollen gets from the stamen to the pistol. She tells them to observe closely so they will be "flower power" botanist experts.

8. START the video, What is Pollination? a few minutes into the tape where the gentlemen instructor says, "So what we want to try to find out today is how pollen moves from one flower to another in nature."

9. STOP the tape after the gentlemen instructs the students that pollination is when the pollen is moved from one part of the flower to another.

Instruct students to record this definition in their Flower Power learning log. Give the students another flower. Let them rub the pollen on their fingers and feel the sticky substance.

RESUME the tape until after the section where the children have taken pencils erasers and pollinate flowers. STOP the tape and let the students pollinate their flowers. Then ask the students if they can remember the three important parts of the flower that it needs to make seeds.

10. FAST FORWARD tape a short section to the blue review screen that asks what are the seed making parts of a flower?

STOP after the review and evaluate as a class to see how much the students understand. Instruct the students that they are going to learn a fun song to help them remember.

11. RESUME tape and learn the song together. Rewind the tape until they can almost sing it alone. The words to this song is to the tune of, "This land is Your Land."

What does a plant need to
Make a new seed?
Three things give flowers
Reproductive powers-
The sticky pollen,
The slender stamen
and pistils that make a flower whole.

12. RESUME tape when he says that pollen has to make a trip from the stamen to the pistil. STOP the tape after the verse of how the pollination is moved.

Have the students sing this verse of the song.

What gets the pollen going
To keep new plants growing?
Different kinds of birds do,
Or the wind that's blowing.
Butterflies and bees,
Carry pollen they need
That's what makes pollination work.

Next have the students divide a page of their FLOWER POWER Booklet into two columns. Write a heading at the top of each column.
Begin the first column with the word Wind. Head the second column with birds and insects. As the tape continues have the students draw an example of each type of flower pollinator. Have the student record characteristics of each type. Sing each verse of the song dealing with each pollinator.

Wind Notes-
1. Blows pollen from grasses and willow and other flowers that have no petals or small petals.
2. Blows pollen from flowers that do not smell or have bright colors.
3. Stamens and pistils are out in the open.

Verse about wind pollinate flowers---

If a flower's not scented,
Not brightly colored,
And the flowers are smaller
In clusters tighter
With stamens longer
the signs are stronger
This plant spreads pollen on the wind.

Birds and Insects notes---

1. Pollen sticks to the hair on bees and other insects.
2. When insects or birds go to the flower for nectar they rub pollen on the pistils.
3. Flowers are brightly colored and have a scent.
4. Sugary nectar

Verse about birds, and insects pollinated flowers.

When bright colored flowers
Have a sweet perfume
And a sugary nectar
Then chances are good
That birds and insects active
Find the plants attractive
They'll spread the pollen as they go.

13. RESUME the tape until the end. Have the students record in the booklets that plants and pollinators have a partnership to make a world a beautiful place.

Verse about the partnership between plants and pollinators.

Pollinators help plants
To make their seeds.
Plants offer food
Pollinators need.
Getting and giving
What they need for living.
That part of the balance of our world.

14. GO BACK to the video, Look Up, Flower and Seeds and watch the beautiful time lapsed photography of the flowers opening towards the end of the video lesson.

PLAY THE TIME ELAPSED PHOTOGRAPHY SECTION OF THE TAPE HERE.
Post-Viewing Activities
1. Provide each student a large piece of blue construction paper and several small colors of paper and tissue paper and pipe cleaner. Have the student create a cut flower, flower garden. Instruct the students that the flowers should be dimensional with stamens and pistils evident. Inform the students that they must have flowers that are pollinated by the wind and those pollinated by insects and birds.

Examples of how to make the different types of flowers are:

Hummingbird Pollinated Flower

Make a tube from orange or yellow or red construction paper. Students may fringe the end of their tubular flower. Have them insert one straw or pipe clean (pistil) and 2-5 pipe cleaners or paper strips for the stamen. Staple the base of the flower closed and attach to the blue paper in the flower garden.

Wind Pollinated Flower

Color nut cup green, brown or pale pink. Punch a hole in base. Cut two pieces of string about 8" long. Knot them together in the center. Pull the knot in the string and one end of a pipe cleaner to the outside of the nut cup. Fasten so that long stamen and pistil stick out of the flower.

2. Have the students write Haiku Poetry about flowers. Glue their haiku flower poetry to their dimensional cut paper flower garden.

3. If this lesson is in the proper season have the students go on a flower identification nature hike and record. Have them take their Flower Power note book and illustrate the flowers they see and make a prediction of how they might be pollinated.

4. Teacher explains that watching flowers grow is a lot of fun. To be an "FLOWER POWER EXPERT" They will be graphing the growth of a plant. Teacher chooses either or both of the following activates.

Grow With Hairy

1. Remove the top one fourth of an eggshell. Rinse out the remaining shell. Use markers to draw a funny face on the shell. Fill the eggshell with soil and a few herb or grass seeds. Keep the soil watered and watch your plant person grow hair!

.2. Record the growth in plant journal. Have the students write a diary entry as if the person they created on their shell is alive and growing up into adulthood.

3. The completed process will reveal a person with a green butch hair style or if you allow the grass to continue to grow for a longer time periods a green straggly haired egg-head.

Green Haired Monster or a Great Looking Kid

1. Take a zip lock baggie and place in the bottom of the bag a very damp paper towel. Staple above the paper towel. This is about one-fourth from the bottom of the bag.

2. Add pre-soaked bean seeds. Seal the bag. Lay bag on the corner of the students desks and record the growth. As it grows to the top of the bag open it and allow the green stems (green hair to grow over the sides and down.)

3. Now the real fun begins! Have the students make a face, and paste it to the front of the bag. The face can represent themselves, someone they know or an individual personality of their "beanie person." The bean growth makes funny hair. Have the students Take the bags and display them on a bulletin board. The students love this activity.
Action Plan
Following the lesson students will have a greater appreciation of flowers and understand how they reproduce. Students will research the importance of pollination. Invite a flowers or botanist into the classroom and discuss cross pollination.

An exciting application for this lesson is to have the students decide how they could make the world more beautiful by using "Flower Power". Students could decide a class project such
as choosing an area in their school yard or close by that they could have a miniature flower garden. The students would research and select the best flowers for their area. Have the students design the garden, plant the seeds and record the growth of their plants. They could make prediction and compare the growth rate of different types of flowers.

If the time of year and weather does not allow an outside garden an indoor classroom growing project can lead to read "Seed Esteem". Begin a class room garden by inviting a florist or botanists to come and speak to the students about growing flowers in a green house. With the help of the quests the students could choose flowers to try to grow in the classroom near a window or under the florescent lighting. The students could then choose the flowers or plants they wish to grow and chart the growth. The students could then decide how they could make the world a better place with the plants or flowers they have grown, such as giving their plants to a nursing home, care center or a sick person that someone may know in the classroom.
Extensions
MATH

Math can be incorporated into almost every science lesson taught. Flower Power multiplication can be bunches and bunches of fun. It teaches the student real, "SEED-ESTEEM".
Have the students tear apart a flower such as a peonies where the seeds are visible. This activity will also work with a fruit such as an apple or orange. Students count the number of seeds in one fruit and then practice their multiplication by calculating the amount of seeds that would be in 10 fruit or flowers, in 20, in 100. Multiplication seed-esteems keeps growing!

LANGUAGE ARTS / LITERATURE

Refer back to the story of Miss Rumphius and asked the students what they will do in their lives to ,"Make the world a better place". Have them create their own story or booklet on their future lives of changing the world.

ART:

Lupine Art (The type of flowers in the story of Miss Rumphius.
Have students create the petals by placing their thumbs in paint and making a thumb print for each individual petal.

GEOGRAPHY:

Research State Flowers. Have students draw on a 3 X 5 index card and connect with a yarn to the place on the map where it is located.

Put on overhead projector as you work through the video lesson to sing each verse between new material learned.
