Creating Colorful Classrooms with Blooming Bulbs

By Angela Carson (Bookerc1)February 1, 2014

As a teacher, I always like to have living things in my classroom (other than the children, of course!). Whenever possible, I keep fish, lizards, or even small rodents, and I always, always have plants in my classroom. Immediately after Christmas is a wonderful time to force bulbs with the kids. I have learned not to begin this project prior to Christmas, as the class misses out on the opportunity to witness the rapid growth, and sometimes even the fragrant blooms, while they are gone over Christmas break.

There are many types of bulbs that are ideal for off-season forcing. One of my favorites is the amaryllis because of its dramatic rate of growth and stunning blooms. Amaryllis bulbs are also widely available around the Christmas season, making them an easy project to start. Once you invest in bulbs, you can enjoy their blooms year after year, without further investment (a key factor for many teachers with limited classroom budgets.) I've included links at the bottom of the article to some excellent articles by Jill Nicolaus (Critterologist) with details on how to extend the life of your amaryllis bulbs.

Forcing most bulbs is ridiculously easy. The one warning I would give for amaryllis plants is to use a heavy pot, rather than a lightweight plastic one, as they do get rather top-heavy, and the custodians will not thank you for extra clean-up if it tips often.

Necessary materials:Amaryllis bulb and pot

  • a heavy pot (clay, ceramic, terra cotta, etc), with a good drainage hole
  • drip tray for underneath the pot, in case of overwatering
  • good-quality potting soil
  • one or more bulbs (odd numbers are usually more visually pleasing)
  • water
  • trowel
  • newspaper to cover work surfaces
  • gravel, marbles, or other decorative materials to cover the dirt, if desired
  • digital camera, if desired, to record growth
  • posterboard or chart paper, to record growth
Amaryllis Supreme, by Jill NicolausIf my pot is 6 inches or deeper, I put a layer of large stones in the bottom, to counterbalance the blooms at the top. I fill the container about halfway with good quality potting soil, often with a pinch of bulb-booster fertilizer, set the bulb or bulbs into the pot, and continue to fill around them. The top 1/3 of the bulb should extend out of the pot. If desired, you can top the soil with pretty marbles, decorative gravel, or moss. I hesitate to do that in my early childhood classroom, due to the choking hazards. Some of those decorative glass "globs" look too much like candy, and multi-colored gravel chips may be mistaken for Fruity Pebbles cereal!

I usually center my bulb-forcing lesson on math and graphing skills. First, we predict how big the amaryllis will get, and estimate when it will bloom. If the kids are unfamiliar with this project, you can also have them guess the color of the blooms. We mark all of their projections on a piece of posterboard, hung near the pot, and away we go! A digital camera is a wonderful tool for this project. I take pictures of the children potting the bulb, and of how it looked when we started the project, and glue them at the bottom of our posterboard. I also write up descriptions of the project, complete with photos, for their assessment portfolios.

Measuring Forced NarcissusAs the bulb begins to send up green shoots, we start measuring. Each week, on Monday, the "Plant Helper" gets out the ruler or measuring tape, and we take a picture of him or her checking the growth since the former Monday. That picture goes above the first one, and we record the measurement, both in centimeters and inches, to introduce both units of measure. If you prefer, you can use non-standard units of measure (how many snap-blocks tall is it?) but the kids love to use tape measures and rulers!

When the buds finally break forth into glorious color, take one final picture for the top of your poster, and record the final measurements. Revisit their earlier predictions, and talk about estimating. They have a great time seeing whose guess was nearest the actual date and measurement, and learn a bit of scientific process without even knowing it. With older classes, you can create graphs, to illustrate the rate of growth, or to compare the differing speed of growth of multiple bulbs. You can also work on sequencing, if you would rather wait until the end and have the students help assemble the poster. Which picture comes first? Second? Next? Last?

Last year, I used hyacinth and narcissus bulbs instead of amaryllis, with greatCaring for Hyacinths success. The stems don't attain the phenomenal height of the amaryllis (sometimes up to a yard tall, from the base of the stem to the top of the blooms), but in a classroom with limited space, that may be a good thing. If you plant different varieties of bulbs together, be aware that they may not bloom simultaneously. Regardless, it was wonderful to have lovely spring bulbs blooming in the midst of a long, gray winter. My only caution would be to remind you that hyacinth and paperwhites are highly fragrant, and will quickly scent your entire room. If you have a small room, or students that are sensitive to scents, you may prefer a less fragrant type of bulb. Autistic children in particular may be extremely sensitive to strong fragrances.

Finally, as the blooms fade, you can wrap up the lesson by explaining how the leaves will continue to produce food and feed the bulb, so they are ready to produce flowers again another year. Many children are surprised to find that the bulb isn't "dead" when the leaves wither, and just requires a little care to come back with more color next winter!

Of course, this project would be excellent to do at home with your children, as well. Learning and discovery should never be limited to the classroom!
