Making pictures using seeds

Go on a seed hunt, act out germination, create seed mosaics, make and eat a plant parts salad, and more in this fun lesson on plants! This is part 1 of a 4 part unit study on Botany and Plants. This lesson is geared toward 2nd-3rd grade level children and their siblings. I created this to do with a weekly homeschool co-op which meets each week for 2 1/2 hours. Use this fun lesson with your classroom, family, after school club, camp, or co-op!

Using a flower and dye to show the importance of stems

Using a flower and dye to show the importance of stems

Introduction

(*At least a few days before your class/co-op, place some popcorn kernels and dried lima beans in moist paper towels. Place the paper towels with the kernels & seeds in a plastic bag. Keep the paper towels moist. The seeds will soon begin to germinate! You'll use the seeds to show the children the difference between monocot and dicot seeds. They are always amazed to see popcorn kernels sprouting!*)

1. Begin your stem experiment:

  • Place white carnation or camellia in water generously colored with food dye. (You could also use celery.) Cutting the stems just before placing them in the water will help.
  • It takes about 2 hours for the dye to show up a little bit in the flower petals if you have very short stems (about 1 inch long). If you use longer stems (about 4-5 inches), it will take about 3 hours.
  • I started soaking the flowers an hour before the class started. When it started, the flowers were still completely white. By the time the class ended, you could see a tinge of color on some of the petals.
  • The longer you leave the flowers in the colored water, the more colorful the flower petals will become.

YOU WILL NEED: a white flower or celery stalk, a disposable cup, and food dye

2. Read Bible story regarding seeds such as Matthew 7:15-23, 21:18-22, & 12:33-37. We read the parable of the sower from Matthew 13:1-23. (Show pictures from Bible stories as you read.)

3. Quickly review plant parts.

Book to use for this entire unit on plants & for activity 6

plant-seeds-lesson-plan

Seed Parts

4. Read "Oh Can You Say Seed?" by Bonnie Worth or "Seeds! Seeds! Seeds!" by Nancy Elizabeth Wallace.

5. Identify monocot & dicot seeds (bean & corn)

  • Look at them under a magnifying glass.
  • Cut them open and observe the parts.
    • Seed Coat/Testa = coat that surrounds it
    • Endosperm = stored food for energy (sugar)
    • Radicle = root system
    • Plumule = tiny shoot = stem & “leaves” but not true leaves = means feather in Latin (Just like babies aren’t born with teeth, plants aren't "born" with true leaves.)
    • Cotyledons = food absorption & storage (becomes first leaves)
  • Discuss the difference between monocot & dicot seeds. (If you need an idea of what to say, read "Exploring Creation with Botany" by Fullbright ahead of time and reiterate that info to them as you dissect the seeds.)
  • Briefly mention the difference between dicot and monocot seeds.
  • Monocot seeds will not separate into two halves. Instead, the food is stored around the embryo. Monocots have one seed leaf, which is generally long and thin, like grass. Some monocot seeds are rice, wheat, corn, coconuts and grasses.
  • Dicot seeds separate into two halves because they have two cotyledons. The embryos of dicot seed are large while that of monocot seeds are small. Dicot seeds contain large plumule and folded plumule leaves, whereas monocot seeds contain very small plumule and rolled plumule leaves. Hilum and micropyle of dicot seeds are clearly visible while that of monocot seeds are not visible. Some dicot seeds include beans, peas, and peanuts.
  • Point out the parts of the seed: cotyledon, plumule, radicle, & seed coat.

YOU WILL NEED PER CHILD: a bean (we used lima beans), corn kernel (from frozen vegetables), plastic knife, and magnifying lens

Collecting Seeds

6. Collect & study seeds.

  • Collect seeds. If weather permits, go outside to collect seeds. If that's not an option, bring some from outside and from in the kitchen.
  • Study the seeds. Note their shapes, sizes, textures, colors, etc.

YOU WILL NEED: A variety of seeds* (either outside or a box of wildflower seeds mix) and a container for the seeds (a plastic sandwich bag or disposable plate)

*If possible, include some more usual seeds like a peach pit, avocado seed, coconut, mango seed, papaya, etc.

Germination

7. Read "One Bean" by Anne Rockwell.

Book to read for activity 8

Acting out germination

Acting out germination

8. Act out Germination ("a seed waking up"):

  • Hand each child candy. This is the endosperm (stored food for energy) that the seed will need to grow before it can begin photosynthesis. The endosperm really is sugar.
  • Also give each child 2 leaves. These will be the cotyledons (first leaves).
  • Help the child completely crawl into a sleeping bag. This is the testa/seed coat.
  • The child is a dormant seed. Once it gets water [pretend to pour a bottle of water over the sleeping bag], warmth, and air, it starts to grow, or germinate.
  • First the testa (seed coat) splits and the radicle (embryonic root) emerges. (Have the student stick their legs out of the sleeping bag to be the radicle.)
  • In some sorts of seeds, the seed gets its nutrients from the endosperm (stored food). The stored food is mainly sugar. (Have the child eat their piece of candy.)
  • The hypocotyl (embryonic stem) and epicotyl go straight up through the dirt. (Help the child stand up. Their legs are the radicle/root, their body is the hypocotyl/stem, and their hands are the epicotyls, which are holding the cotyledons/seed leaves.)
  • The cotyledons (seed leaves) emerge. (Have the child stick out the 2 leaves from out of the sleeping bag.)
  • The testa/seed coat falls off and the plant grows as the taproot shoots down and the epicotyl straightens. (Have the child stand up all the way and allow the sleeping bag to fall off from the tops of their head.)
  • YOU WILL NEED PER CHILD: 2 construction paper or real leaves, a sleeping bag, & a piece of candy

9. (If you have extra time) Color or draw the stages of the germination of a seed.

YOU WILL NEED PER CHILD: (per child) a sheet with germination illustrated or a blank paper sheets pre-cut and crayons

Seeds for a Garden

10. Read "How Groundhog's Garden Grew" by Lynne Cherry.

11. Look at backs of seed packets and what the information means.

YOU WILL NEED: seed packets

12. Talk about faith of a mustard seed (Mt. 13). Pass out mustard seeds & compare with other seeds. Plant them in soil. Talk about planting seeds & sharing God's word (Is. 55:10-11). Guess (Hypothesize) which seed will sprout the fastest.

YOU WILL NEED PER CHILD: mustard seed & other seeds

Book to read for activity 11

Making seed mosiacs

Making seed mosiacs

Seed Mosaics

13. Create Seed Mosaics.

  • Look at pictures of mosaics.
  • Ahead of time cut out a piece of cardboard piece in a circle or other shape. Alternatively, use a paper plate.
  • Allow children to draw a simple outline of picture. (Adults can draw the picture if needed.)
  • While children are drawing, paper punch a hole for string or twine so you can hang it up later.
  • Squeeze a generous amount of glue on your picture over the outline and inside the lines.
  • Press your seeds into the glue! (It helps to start in one area instead of placing them all over the place in random areas. When it’s time to fill in the background, cover that area with glue & just sprinkle the beans, lentils, or rice over the area.)
  • Let the picture dry for at least 2 hours before threading twine or yarn in the hole to hang up your seed mosaic.

YOU WILL NEED: dried beans (black beans, white navy beans, pinto beans), dried split peas, dried lentils, glue (tacky glue works best but liquid Elmer's glue also works), a paper hole punch, yarn or twine, & cardstock or other heavy paper (such as a piece of cardboard from a cereal box) OR paper plates

Talking about roots

Talking about roots

Roots

14. Collect and study roots.

  • If weather permits, go outside and pull up weeds and study using magnifying glasses. If weather isn't permitting, tell the children to bring a weed with its roots from home.
  • What do you notice about the roots? Look at them using a magnifying glass. What else do you notice about them?
  • Talk about being rooted in the word.

YOU WILL NEED: plants with roots attached (either collected from outside or brought from home) & magnifying glasses

Plant parts salad

Plant parts salad

Plant Parts Salad & Review

15. Make a salad out of various plant parts:

  • First make poppy seed dressing using 1/2 cup sugar, 1/2 cup lemon juice, 2 teaspoons diced onions (or dried), 1 teaspoon mustard, 1/2 teaspoon salt, 2/3 cup oil, and 1 tablespoon poppy seeds.
  • The salad will have dressing with poppy seeds (seeds), lettuce (leaves), celery or asparagus (stalk), tomato or diced apple or other sliced fruit (fruit), & carrots (roots).
  • Ask children to match plant parts to vegetables & then carefully chop vegetables.
  • Eat the salad.

YOU WILL NEED: measuring spoons, liquid measuring cup, jar with lid, large bowl, plastic forks, disposable plates, cups for water, napkins, knives and cutting boards, 1/2 cup sugar, 1/2 cup lemon juice, 2 teaspoons diced onions (or dried), 1 teaspoon mustard, 1/2 teaspoon salt, 2/3 cup oil, 1 tablespoon poppy seeds, lettuce, celery or asparagus, tomato or diced apple or other sliced fruit, & carrots

16. Look at flower or celery (from activity 2) and discuss what occurred. Let each child or family take 1 flower home.

17. (If you have extra time), find plants outside, identify parts, mount on cardstock, and cover with contact paper.

18. Review what we learned.

Watching seeds germinate - We used bean plants and pumpkin seeds.

Homework: Growing a Bean Plant

Send children home with a bag of dried beans. Tell them to put them in wet paper towels in a bag or clear plastic cup. Keep the paper towels wet and tell us next week at co-op what you saw happen.

  • Oh Say Can You Seed?: All About Flowering Plants (Cat in the Hat's Learning Library) by Bonnie Worth is written in the rhyming Cat-in-the-Hat manner and includes a great overview of botany!
  • What Kinds of Seeds Are These? by Heidi Bee Roemer is another fun picture book on seeds that is good for young children.
  • Flip, Float, Fly: Seeds on the Move by JoAnn Early Macken and
  • Who Will Plant a Tree? by Jerry Pallotta are both fun picture books on seed dispersal. They are simple with nice illustrations and are ideal for preschool and early elementary-aged children!
  • A Seed Is Sleepy by Dianna Aston has gorgeous illustrations and includes lots of fun tidbits about various seeds.
