To celebrate spring, I’m sharing some spring science experiments middle school. Also, look at my page How to Successfully Homeschool Middle School and 4 Weeks Free Spring Unit Study & Best Hands-on Ideas for more ideas.
Also, we are creating an amazing display for a simple flower dissection but level it up a bit for middle schoolers.
This flower dissection display is wonderful for a home project but can be used for co-op presentations or just to take the ordinary to something more extraordinary while learning.
The structure and functions of flower parts all contribute to the intricate process of pollination.
Pollination is essential for plant reproduction and what better way to learn about each one than to dissect and label each.
You can use real flowers if you like or faux silk flowers so that they keep longer.
Try to choose flowers that clearly display the plant’s structure like lilies, tulips, daffodils, alstroemerias, and gladiolus.
By attracting pollinators, producing and receiving pollen, and protecting the developing seeds, flowers play a vital role in the life cycle of plants and the ecosystem.
Let’s look at the role of each part of the flower and where it fits into this
PARTS OF A FLOWER
Sepals: Often green and leaf-like, sepals form the outermost layer of the flower bud.
Their primary function is to protect the developing flower inside from drying out, damage, and pests. In some cases, sepals may be brightly colored and resemble petals, aiding in pollinator attraction. Once the flower blooms, sepals may remain as a support structure or wither away.
Petals: The most visually striking part of a flower, petals are often brightly colored or uniquely shaped to attract pollinators. Their colors, patterns, and sometimes even ultraviolet markings serve as signals to guide insects, birds, and other animals to the flower’s reproductive organs.
Some petals produce scents to further entice pollinators, while others have specialized structures to facilitate landing and pollen collection. In some flowers, petals may also play a role in protecting the reproductive organs from the elements.
Stamens: The male reproductive organs of a flower, stamens are responsible for producing pollen grains, which contain the male gametes. The number, shape, and arrangement of stamens within a flower can vary greatly, often reflecting adaptations for specific types of pollination.
Each stamen consists of two parts:
- Anther: The sac-like structure that produces and releases pollen.
- Filament: The stalk that supports the anther, positioning it for effective pollen dispersal.
FLOWER PARTS
Pistil/Carpel: The female reproductive organ of a flower, the pistil (or carpel) houses the ovules, which, after fertilization, develop into seeds.
A pistil typically consists of three parts:
- Stigma: The sticky or feathery tip that receives pollen grains.
- Style: The slender stalk that connects the stigma to the ovary.
- Ovary: The enlarged base that contains the ovules.
The ovary may be located superior (above the other flower parts) or inferior (below the other flower parts), depending on the flower type.
Receptacle: The expanded tip of the flower stalk where all the other flower parts are attached.
It provides structural support for the flower and may also play a role in the development and dispersal of seeds.
In some flowers, the receptacle becomes fleshy and forms part of the fruit, aiding in seed dispersal.
Leaves: The main function of a leaf is to produce food for the plant by photosynthesis. Leaves also provide structure and support, store water and nutrients, and help regulate temperature.
Stem: Stems provide support the the flower. It also transports water and minerals from the roots to the rest of the plant. They also produce new growth to extend the life of the plant.

SIMPLE FLOWER DISSECTION SPRING SCIENCE EXPERIMENT MIDDLE SCHOOL
You will need:
- Corkboard
- Patterned scrapbook paper
- Push pins
- 3×5 cards
- Real or silk flowers
- Scissors
- Letter stickers
Take your corkboard and decorate it with patterned scrapbook paper, stickers, ribbon, or washi tape.
You can glue these pieces on but if you want to be able to use your corkboard for other things just attach everything with clear push pins.
Have your child first label 3×5 cards with the name of each flower part by hand or using stickers.
And a short description of each.
Use scissors to carefully take apart each section of the flower and tape or glue them to the corresponding cards.
Arrange the cards around the board for display.
Don’t forget to make a title for the top.
