Plant resources for teaching & learning

Questioning is the foundation of all learning.
The first step in rejecting not knowing is to ask, why?

Introduction

Plants are important food sources for the survival of animals and enhance the beauty of the world.

This page includes resources for teaching and learning about plants for primary and middle level learners. Analysis of information need to construct concepts about plants in meaningful ways. Information about plants and their properties. Properties of leaves, flowers, fruit, trunk anatomy, spirals in plants, and plant cells.

Background information for planning plant activities

Information is organized into categories as in this framework and explaned here.

Created by - Courtney Maas & Jennifer Thomas

Topic - Plants

Focus question - What are characteristics of plants?

Perceptual Responses

  • See - observation - location, shape, color, size
  • Feel - texture, sharp, light, hard, fragile, soft, fuzzy, and smooth while others are
  • Thorny and rough
  • Smell - sometimes have a good smell, some not so good or bad
  • Taste - can eat some plants
  • Hear - leaves rustle, needle clack

Properties

- Flowering plants

  • Seeds have a seed coat, embryo (baby plant) and cotyledon (stored food)
  • Plants - mon cot, dicot, biennial (life cycle 2 years) perennial (life cycle 2 or more years)
  • Flowers have petals, stamen, pistol, anther egg, filament
  • Germination, photosynthesis,
  • Bulbs
  • Fruit
  • Stems, twig, branch, trunk
  • Leaves
  • Needles - cones
  • Roots

- Non Flowering plants

  • Ferns - leaves, fronds, spores,
  • Mosses
  • Horsetail

Relationships and concepts

  • Plants are living
  • Plants create energy from sun for food
  • Plants reproduce
  • Fruits and vegetables can grow from a plant.
  • When you plant a seed in good soil, water it, and provide sunlight, a plant will grow from it.
  • Plants have leaves, stems, petals, roots, flowersPlants have a life cycle
  • In order to get plants, you need to have air, water, soil and sunlight.
  • You plant watermelon seeds and take care of them so that they grow into watermelons. Then you can eat the watermelon.
  • You plant the seeds from the watermelon you eat and grow more watermelon - life cycle of a seed.
  • Do plants have feelings? Do they have senses?
    • Plant Mimosa pudica seeds and after they have a second set of leaves, touch the leaves and discuss what happens.
    • Venus fly plants
  • Do plants need soil? gardening without soil. Grow mint seeds on sponges, move to holding trays in a hydroponic unit.

Observations

  • Observe that plants can be different colors, shapes, & sizes.
  • Observe all the flower parts - look, feel, taste, smell, hear.
  • Observe seeds can be all different colors, shapes, & sizes.
    • A bean seed is kidney shaped and white.
    • Lettuce comes from a little tiny seed and tastes good.
  • A rose smells good, has thorns on the stem and comes in many colors.
  • Some seeds are edible and taste good and some seeds are just for making something taste better.

Transformations

  • Drawing pictures of plants and label their parts.
  • Make a chart and list plant parts across the top - leaf, stem, flower, root, seed, other use store and labels to classify under column
  • Seed collection with labels ...Go to store - collect different plant parts, take to school, cut apart - count seeds, dry seeds, plant seeds...
  • Chain story - Watch seeds grow... Draw pictures, measure growth, communicate what is happening with a chain story. When we plant a seed for sweet corn, it grows into a corn plant. We need soil, air, & sunlight for it to grow. After it grows, we can pick it and eat it. The cycle can then start all over again.

Tasks or Activities

  • Hand out bean seeds for the kids to observe and talk about
    • Open up a seed to see the inside. Fill out parts of a seed and chart
    • Compare different types of seeds - for what purpose?
  • Plant seeds and put one in the dark & one in the sunlight.
  • Go on a field trip to a greenhouse to learn about different plants.
  • Go on a nature walk to look at different types of flowers & plants on a nearby walking trail or in the neighborhood to explore different types of plants
  • Go to a grocery store to learn about all of the different plants we can eat. - collect different plant parts take back - classify, cut apart - count seeds, dry seeds, plant seeds..
    Collect different plants parts take back - classify, cut apart - count seeds, dry seeds, plant seeds...
  • Plant a seed

Real World Value Application

  • We eat all kinds of plant parts - flowers, stems, roots, seeds, fruit,
  • Plants that we eat are good for us and give use energy, vitamins, and minerals
  • When you plant a garden, you can provide food for your family and friends
  • Gardening is a hobby
  • Flowers make your yard look pretty
  • Plants can be good for the soil
  • Make mulch, fertilizer
  • I can understand the world
  • Understanding the world gives me.... power
  • Plants make our world beautiful.

Classroom atmosphere

  • Hands on real life activities motivate and empower learners to explore and learn about their world.
  • Working in groups to explore plants encourages cooperation; and sharing learning experiences creates positive learning experiences and positive attitudes for science and achievement.

Assessment levels

  • Upper level - Plants have many different properties, but all have the ability to use energy from the sun to grow and store it for them to use and other animals to use.
  • Lower level - Plants grow, but don't move from place to place.

Instructional assessment

  • Learners ask questions and participate in the activities.

 

Vocabulary

Stem - holds up the flower

Sepals - the outermost ring of flower parts. It protect the bud; usually green but can be the same color as the petals.

Petals - Often in a ring of flower parts. They attract pollinators, often giving them a landing place; often colorful, may also make scent to attract pollinators.

Stamens - Often inside the ring of flower parts. Produce and hold the pollen. Made of

  • Filament (the stem),
  • Anther (the canoe-shaped structure at the tip that holds the pollen, and
  • Pollen, the tiny grains on the anthers.

Pistil(s) - At center of the flower, may be one or more. They act as catcher for pollen, container for the ovule(s). Pistil is made up of

  • Ovary - A vase-like structure
  • Style - the stem-like structure
  • Stigma is at the top of the style and has a sticky substance. to catch and hold the pollen.
  • Ovules (found inside the ovary, often look like tiny white beads) – become the seeds when fertilized by pollen that has landed on the stigma.

Nectar - Is the sweet reward for pollinators. It is located in the nectaries that can be located:

  • At the base of the Stamen, the male pollen-producing stalks.
  • Base of the Ovary. At the very bottom of the female central structure.
  • Petal Spurs. Inside long, hollow tubes or pockets formed by the petals.
  • Extrafloral Nectaries: Are outside the flower entirely, such as on stems or leaves, to attract insects like ants.

Fruit - The seed-bearing structure of a plant. The sweet and fleshy product of a plant that contains seed and can be eaten as food. Fruit types.

Non seed plants

Horsetail

Horsetail (Equisetum) is a unique "living fossil" plant known for being an ancient survivor, having an extremely high silica content, and reproducing via spores rather than seeds. Related to ferns as a fern ally.

Natural sandpaper: Because the stems absorb high amounts of silica, from the soil, the plant has a rough, abrasive texture. Historically used for scouring pots and polishing wood or metal.

Flowers

Some common flowers -Angiosperms

Tulips

Early spring flowers - Tulips & crocus.

Irises

Irises
Have seeds, but they also havve bulbs and rhizomes.
A rhizome is a horizontal underground stems.
Bearded irises actually need the top part of the rhizome exposed to the sun and air so they do not rot, hence exposed rhizomes.

Leaves are long, flat, and sword-shaped, growing in stiff, fan-like clusters from the base of the plan with parallel venation.

Sweet Clover in a yard. Provides nitrogen
