Flower Lesson Plans

Compare Flowering Plants

Different flowers can be compared to find their similarities and differences. Ask the student(s) to show ten different types of flowers. Remind them that in addition to garden flowers there are also flowers on trees and bushes.

The student can collect pictures or specimens of the different flowers.

Fold a paper in half. List the similarities on one side and the difference on the other.

Learn the Parts of Flowers

Students will quickly notice that all flowers have certain external parts. Start by teaching the non-sexual parts of flowers. They are already familiar with these parts of flowers.

Non-Sexual Parts of Plants

Petals

Colorful, outside part of the flower

Leaves

Where photosynthesis takes place in the flowering plant

Stalk

Supports the flower

Sepals

Protects the flower when it is a bud

Receptacle

Expanded tip of stalk that the flower grows out of; found at the bottom of the flower

Pistil - Female Parts of Flowering Plants

After identifying the non-sexual flower parts, it is time to learn the female parts. These are found inside the petals. First look at the picture on the worksheet, as well as opening a flower and finding these parts.

Stigma

Has a sticky surface to trap pollen, found sticking out of the petals

Style

Holds up the stigma; like a stem inside the petals

Ovule

Potential seed
The female gamete of the plant which may produce the new flower

Ovary

Holds the ovule or female gamete

Stamen - Male Parts of Flowering Plants

Explain that plants have male and female parts just as animals do. However, flowering plants are unique in that they have both male and female in one specimen.

Anther

Makes the pollen, which is the male gamete

Filament

Holds up the anther

Botany Projects

Flower Poster

Take apart at least six different flowers and identify the parts. Use contact paper to make the poster.

Coloring Book

Students can develop their own coloring pages by drawing different flowers. There is an unbelievable variety of structure, size and color even though the same flowers parts are present. Students may also choose to use any artistic medium to identify different flowers.

Flowers Inside Of Flowers

Some flowers, such as Blue Gem or Lantana, have flowers inside of flowers. That means that the petal of the flower is actually another flower with its own sepal.

Queen Anne's Lace has been called a flower inside a flower inside a flower.

How many complex flowers can you find?

Plant Your Own

Plant your own flowers, inside or out. Some fast growing flowers include sunflowers, marigolds, zinnas and snapdragons. Young and adult alike take pleasure in seeing the small seeds turn into sprouts and then flowers. They can identify their organs as they become visible.

You can also design an experiment where one type of flowering plant is exposed to different conditions (changes in soil, water, amount of sunlight or shade, inside or outside conditions.) Certain aspects of the plant can be measured in different conditions.

Experiment: Essential Oils from Flowering Plants

Essential oils are steam expressed from plants, and some aromatic oils are expressed from the petals of flowers.

Do you think the essential oils will benefit or hurt a plant when added to their soil? You can conduct an experiment of a flowering plant like lavender or geranium that also has commonly available expressed essential oils.

You will want to have two or three plants that are not exposed to the essential oil as a control. Other plants can have the oil added to the water applied to their soil. Other plants might have the essential oil dissolved in water and spritzed (lightly sprayed) on their flowers.

Can you predict any differences that might be found in a plant that is exposed to the essential oils from other flowers of the same species, and those that are not exposed?

Flowers to Eat

Marigold Spinach Surprise Salad

• Marigold petals (wash thoroughly)
• Spinach (or other leafy green)
• Cherry tomatoes cut in half
• Thinly sliced cucumber
• Celery diced

Fruit Salad with Rose Petals

Another sweet surprise is rose petals in a fruit salad. Wash the leaves thoroughly to make sure any chemicals are washed off.

• 1 cup of rose petals - separated & washed
• 1 cup of kiwi - sliced and quartered
• 1 cup of strawberries - sliced
• 1 cup of blueberries
