Meet Melyssa Guzman. She is one of 20 College First students who spent eight weeks learning about environmental science and doing a research project at the Chicago Botanic Garden.

College First student Mely G. would like people to plant butterfly gardens in their yards.

Mely, as she likes to be called, is a junior in the Chicago Public Schools district. She’s kind of a “girlie” young woman who wears a lot of pink, and likes flowery, feminine things. Mely also loves science. Each student had a staff mentor; I was Mely’s. Her project was teaching the public about butterfly-attracting flowers.

Although drop-in programs and exhibitions may be considered more “education” than “science,” understanding how people learn is an area of social science research that can challenge a smart student like Mely. This summer, Mely learned that museums and public gardens often test exhibitions and learning activities, using methods similar to those practiced by conservation scientists, to see how visitors will respond.

Mely began by researching butterflies and the flowers they prefer. Then she decided to set up a display at the Butterflies & Blooms exhibition, where she would teach visitors what flowers to grow in their yards to attract butterflies. The display would have different kinds of flowers—real flowers and pictures—and she would stand and talk with people who were interested.

After each group of visitors, Mely recorded notes about how long they stayed at her table, and how interested they seemed.

As kids today would say, her first try was an “epic fail.” Most visitors looked at her display with curiosity, but they seemed perplexed and did not stop to learn more. The display was lovely, with fresh flowers and pictures of native butterflies, but it lacked a clear focus. It needed something else to draw visitors in. The display board kept blowing over, which was another big problem.

Back to the drawing board: Mely made a new display— one that would stand up better and entice visitors with a title that asks: “What Is a Butterfly Flower?”

Mely brought the exhibit inside and modified the whole thing. Instead of using a folding display board, she mounted a poster board on a cardboard box so it would be more stable when taped to the table. She added a title, “What Is a Butterfly Flower?” as well as some facts about butterfly flowers. Then she tested the display again. After each group of visitors, she recorded the time they spent at her table, and gave them a score of 1 to 4 to rate how interested they were, the kinds of questions they asked, and things they talked about while looking at the display.

Museum exhibit developers call this process “rapid prototyping.” Inexpensive mock-ups of exhibits are tested to ensure they work—that visitors enjoy them and get the intended messages—before the museum invests a lot of money on a permanent display.

A mother and daughter listen as Mely explains what colors, scents, and shapes attract butterflies to a flower.

Mely made a few more minor changes to her display. Then she tested a hypothesis. She observed that adults with children seemed more distracted than those without children; that they did not seem to talk to her as much as the childless groups. She hypothesized that adults without children would spend more time, ask more questions, and talk more about butterflies than mixed-generation groups. She used the data she gathered during prototyping the display, analyzing who stopped by her table, how long they spent, and how engaged they were.

Surprisingly, she discovered that families with children actually spent a little more time on average than adults alone. She thought this may be true because adults who brought children to her display spent their time explaining things to them instead of talking to her. In other words, the adults were not distracted, but were directing attention on their children to help them also learn from the display.

Mely does not fully realize that she has stumbled upon a very significant principle of learning: that learning is social. Educational research has shown that interaction between family members has a positive influence on learning in museums and in other environments. I’m very proud of Melyssa’s accomplishment this summer, and I look forward to seeing her expand her research next summer—because we both learned something!

One of our favorite insects at the Chicago Botanic Garden is the praying mantis. So we were very excited to obtain an egg case earlier this spring. We decided to keep it indoors so we could watch it hatch, and then release the newly hatched insects into the Garden.

About 100 praying mantises emerged from this ootheca and were released into the Grunsfeld Children’s Growing Garden.

A praying mantis egg case is called an ootheca (pronouned oh-uh-THEE-kuh). The plural is oothecae (oh-uh-THEE-see). The ootheca was produced by a female praying mantis last fall. She laid her eggs in this foam of protein that hardened around a stick and protected the eggs through the winter. The eggs usually hatch in mid-June to early July. The half-inch-long immature praying mantis nymphs resemble the adult, but they do not have wings.

Colorless praying mantis nymphs emerge from the ootheca all at one time. During their first hour, they darken in color to blend in with their surroundings.

After our praying mantises hatched inside an insect cage, I discovered that a bed of false sunflower plants (Heliopsis helianthoides) in the Grunsfeld Children’s Growing Garden was infested with red aphids. I released the praying mantises, and the hungry babies immediately began to feed.

At first, the praying mantis babies seemed a little bewildered by their new surroundings, but they quickly acclimated.

This mantis held very still as it eyed its prey.

These four little mantises lined up and stared at the aphids that would certainly become lunch soon.

It wasn’t exactly aphid carnage—much to the disappointment of our eighth grade Camp CBG helper, Joshua, who assisted me with the release—but the young predators did appear to enjoy their first meal.

By the end of August, some of our little friends will be as big as this praying mantis (and just as hungry)!

It may surprise you to know that although it looked like a bad infestation, aphids are not really a big problem for the plants. When they are very abundant, it does not take long for natural predators like praying mantises and ladybugs to find them and move in for a feast. Predatory insects will take care of the problem if you are patient and let nature take its course. If aphids show up in your garden and they bother you, we recommend hosing them off with water rather than using an insecticide, because chances are pretty good that there are beneficial insects on your plants, too. Hosing with a strong jet of water will knock off all the bugs and kill most of the aphids, but it won’t be as devastating to the mantises or other beneficial insects as poison.

We have placed praying mantis oothecae in the Regenstein Fruit & Vegetable Garden and Elizabeth Hubert Malott Japanese Garden, as well as in the Children’s Growing Garden, to ensure that there will be a population of our favorite insect for you to find. Many of them will survive on aphids and other insects they capture and devour on our flowers, and they will grow up over the summer. The next time you visit, stop by and see if you can find them helping our plants remain healthy and less bothered by pests.

Having three daughters in middle school means trying to find a nice way to show my appreciation to all of their teachers. When I say “all” for the middle grades, that is not just three teachers any more, because they have separate teachers for each subject, as well as “special” teachers for art, gym, music, and library. And then there is the office staff members who were really nice and helpful during the year.

Do I need to give everyone something? Certainly not. But I would like to end the year on a pleasant note and say “Thanks!” for serving my three children—without spending too much money, that is. The answer is plants (which is what you expected from a Chicago Botanic Garden blogger, right?). 

PHOTO: A flat of 3-inch lavender pots.

This flat of lavender came in pots with care labels. All we need to do is add thank-you notes.

Every year, I go to a local nursery and buy a few flats of herbs or flowers. I prefer going to a local, small nursery or greenhouse rather than a large franchise store that sell other products. The plants tend to be in better condition, and supporting local businesses is good for the community. And it’s fun meeting and getting to know small business owners.

My daughters help choose the plants, which means we usually get purple flowers of some kind. If the plants come in cell packs, we transplant them to inexpensive containers. Otherwise, we give them as they come from the nursery. It does not have to be fancy to make everyone happy.

We make a thank-you note on the computer. It includes information about how to care for that plant. Then we use use bamboo skewers (left over from making rock candy!) or plastic forks to hold them in place.

We used a bamboo skewer to attach a thank-you note and oregano care instructions.

One teacher requested a plant for a shady yard, so we included some lily of the valley in the selection, and used a fork to attach a thank-you note.

I set aside one plant for each daughter to personally present to her homeroom teacher. I bring the rest of the plants to the school office during the last week. After years of doing this, the office staff now anticipates the delivery as if it’s Christmas. (I also bring a package of paper lunch bags so teachers have a clean way to carry their plants home.)

The principal makes an announcement during the school day that any teacher who would like a plant can pick one up in the office—first come, first served. Even if a teacher doesn’t want to take a plant (I’m pretty sure the computer lab instructor at our school is not interested), he or she can enjoy looking at them and smelling them in the office. That takes care of everyone I want to thank. All plants are claimed by the end of the day.

Creative wording makes writing the notes fun.

If this works for me, it can work for you, too. If plants are too much of a hassle or expense, consider giving seeds instead. Attach a ribbon with a note to let the teacher know your gratitude. You can say something cute such as “Thanks for helping me grow!”

Or use a clever rhyme:

Just like the year I spent in your room, I hope these seeds germinate, grow up, and bloom.

Looking for another idea? There’s always Bottle Cap Bouquets, which delight teachers and mothers alike. Cheap and cheerful!

I wasn’t sure how much the teachers appreciated the plants until one teacher asked my daughter if I would be bringing plants again, and what kind they might be. She was looking forward to the end of school, but she was also looking forward to taking home a plant to start the summer.

Bottle Cap Bouquets

Kathy J. —  May 4, 2014 — 3 Comments

Miniature flower arrangements offer a charming and whimsical gift for mom, grandma, or anyone special. A nice feature of these tiny bouquets is that you can show off the beauty of small flowers that always sing backup to showier blossoms in large arrangements. Also, you can use aromatic herbs with small leaves as filler greens to add a pleasant scent.

This little arrangement of mini-carnations, baby’s breath, and a sprig of sage has pink burlap ribbon wrapped around the bottle cap to mimic a fancy basket of flowers.

What you need:

  • A cap from a plastic bottle, such as a milk container or soda bottle
  • Floral foam (the wet kind)
  • A bunch of small flowers—I used mini-carnations, waxflowers (Chamelaucium uncinatum), and baby’s breath (Gypsophila paniculata)
  • Fresh herbs (thyme, rosemary, and lavender work well because they have stiff stems)
  • Optional: ribbon for added decoration

The directions are pretty simple.

Cut the floral foam to fit the inside of the bottle cap. Start a little larger than you need, and then trim it to fit. Push it into the cap. If your cap is narrow, like a milk bottle cap, you may want the foam to be above the level of the cap so there is enough room to hold the flowers. Otherwise, trim the top so the foam does not stick up. Add water to soak the foam.

Trace the cap on a piece of foam and then carve the foam with a butter knife to fit inside the cap.

Begin sticking the flowers into the foam. Here, we started with a waxflower in the center and added smaller flowers and herbs around it.

Cut the flower and herb stems about 3 inches. You can trim them shorter depending on the desired height in the arrangement. Stick them into the foam. You might want to start with one of your larger flowers in the center and then add smaller flowers and herbs around it.

Waxflower, baby’s breath, and rosemary complete this delicate arrangement.

Not into pink? This yellow cap with baby’s breath and thyme is fragrant and cheerful.

When you are satisfied with your floral creation, you can either leave it as is—especially if the color of the bottle cap looks nice with the flowers—or you can tie a ribbon around the bottle cap. The best way to keep it in place is by using a few drops from a hot-glue gun.

Surprise! An old contact lens case becomes a miniature garden of waxflower and thyme that smells as amazing as it looks.

Tips

When using a shallow bottle cap, limit the number of larger flowers like mini-carnations or mini-daisies to three or fewer. Floral foam has limits. Adding too many flowers will cause the foam to fall apart and the flowers to flop over. If the first attempt suffers from floppy flowers, start over with a new piece of foam and add fewer flowers. 

If you really want more than three large flowers, use a taller cup, such as a medicine cup from a bottle of cough syrup, as the vase. Even then, take care not to overload the foam. This is a small bouquet, after all!

Precious and colorful, these-mini bouquets will stay fresh and bring cheer for a few days.

Floral foam is irresistible. Your kids, even teenagers, will want to play with it. Parcel it out in small pieces so they don’t play around with the whole block before you can use it. 

You can use the same procedure to make a mini-dried flower arrangement; just don’t wet the foam. Any way you make them, these little bouquets are sure to bring big smiles from someone you love.

Are you tired of winter? Silly question—we all are. Spring is way overdue.

Cheer up! The Garden has an answer to the dragged-out-winter blues: Vertverre (green vision) glasses. Put on a pair of these specially designed glasses and you’ll see the drab landscape turn into a time when spring came six weeks early.

PHOTO: Google glasses showing a spring view through the prism, while the landscape is brown and wintry.

Using Google.AFD glass technology, the user’s experience of spring seems real.

Our sense of sight is a curious thing, and it can be manipulated to affect our outlook on the world. In the 1950s, a scientist created a set of vision-flipping goggles that made the world appear upside down. The first people who tested these glasses couldn’t even walk without stumbling when first wearing them. Eventually the brain adjusts, so that wearers see the world right side up again through the lenses. That is part of the scientific principle behind Vertverre.

Garden staff approached Google.AFD about this idea two years ago when we realized the wonderful health benefits of experiencing an early blooming spring. Google.AFD works with not-for-profit organizations like the Garden to develop tools and technology for a better world. While creating sense-altering vision seemed like a stretch, Google.AFD techies were already working on several devices to enhance retina viewing, so the partnership turned out to be a natural fit.

Vertverre™ technology turns the clock
forward, turning this…

…into this lush, verdant landscape.

How does Vertverre work? The lenses in these glasses send a signal to your retina, which transmits to your visual cortex, releasing a memory of that early blooming spring from years past. When you look at the landscape, Vertverre tricks your eyes into remembering spring flowers, green grass, from warmer times. The effect is so stunning that it has the same mood-enhancing effect as light therapy. Instantly you feel healthier and have a more positive outlook on life.

As the French philosopher Henri Bergson wrote: “The eye sees only what the mind is prepared to comprehend.” Come visit the Garden and see for yourself. We only have a limited number of prototype models for our visitors and are taking reservations on a first come, first serve basis.
