The Garden is a great place for people of all ages to learn to about plants and the natural world. These posts relate to programs offered for children and youth, but also offer educational information for the adults in their lives as well.

Kids Get Crafty

Amy Wells —  May 21, 2013 — Leave a comment

My 3-year-old son and I have enjoyed many seasons of Little Diggers. We have learned new things together and have had  a lot of fun with the projects—but our favorite project so far this year was with insects. We got up close and personal with ants, butterflies, grasshoppers, and ladybugs. The instructor set up habitats in mesh containers where we could look at each group of insects with magnifying glasses and two-way viewers—the same tools real scientists use every day!

After looking at all the insects up close, we talked about all the different body parts an insect has, and why that makes an insect an insect and not a spider or another bug (even though they have a lot of the same body parts). All insects have three body parts (head, thorax, and abdomen), six legs, antennae, eyes—and sometimes wings! We remembered what the body parts were and where they go by building our own model insect. It was really easy—a fun and funny way to teach our little people about the different parts.

You can build your own model insect at home, too. Here’s what you’ll need:

  • An egg carton—Cut into strips of three eggs-worth. You can get four insect bodies out of one egg carton, so you can explore and make more than one kind of insect.
  • Coffee filters—Cut these each into six pieces for wings. You can see how to cut them from the photo of our completed insect below.
  • Pipe cleaners—Cut these into 3-inch pieces for legs.
  • Craft supplies to decorate and color your insect—Use feathers, googly eyes, crayons, gems, and tacky glue. Insects come in all shapes and sizes from simple black ants to very colorful, shimmery beetles. Have fun creating!

Use these materials to build your own insect.

As we built our insect and decided what it should look like, we talked about the different parts of our particular insect. We put antennae and one eye on the head, a feather and another eye on the thorax, and wings on the abdomen—and this was fine by me! While he was hesitant to put parts where they should go, he said “head,” “thorax,” and “abdomen” out loud as we built and talked about our insect. He was very proud of this final specimen.

Every class we go to uses different activities to explore a different theme. We’ve used play dough, enjoyed circle time with great books, gone on Garden walks, and let’s not forget our favorite activity, planting! (This time we planted some Mexican heather as part of the insect theme. Butterflies and bees love the nectar from the flowers of this plant.) We planted our heather at home and are waiting to see if we get visitors this summer.

Our finished project!

We can’t wait until the fall season of Little Diggers, but if you don’t want to wait, you can sign up for My First Camp for 3-year-olds, and enjoy more hands-on science, art, food, and gardening.

True or false: There’s a spider 3 feet away from you right now.

A "save-the-date-for-World Environment Day" quiz

The (female) cross orbweaver spider, named for the cross on the top of her abdomen.

First things first: Mark your electronic calendar for June 1! That way you won’t miss out on the Garden-wide celebration of World Environment Day.

It’s a day to meet our scientists and horticulturists, to see the Daniel F. and Ada L. Rice Plant Conservation Science Center in action, and to check out senior ecologist Jim Steffen’s very cool display table on native spiders, which promises to be a kid magnet (live specimens, a big model spider, lots of good spider stories). 

After you’ve saved the date, work this quiz with every kid you know:

1. Spiders can fly. TRUE. Some spiders travel through the air by “ballooning”—sending out a thread of silk with a clump like a parachute at the end that carries them up into the air, where they swing along like Spiderman! Spiders have been found as high as 10,000 feet in the air and 200 miles out to sea.
2. Spiders can fish. TRUE. There’s a group called fishing spiders that can capture everything from tiny water insects to fish as big as a minnow!
3. Spiders can eat their own webs. TRUE. Webs get damaged all the time, so web-weaving spiders recycle their own silk by simply re-ingesting it. (It’s full of valuable nutrients.) Then they rebuild their web—sometimes every day!
4. Spiders have two eyes. FALSE. Almost all spiders have EIGHT eyes, the better to watch their prey while holding completely still. Some spiders have two bigger eyes, like binoculars, up front so they can focus on moving prey.
5. Spiders have stingers, like Shelob in The Lord of the Rings. FALSE. Spiders inject their prey with venom through fangs at the end of their jaws, which are called chelicerae. They don’t have stingers.
6. Spiders mummy-wrap their prey, like Shelob did in The Lord of the Rings. TRUE. That’s how they keep it from escaping.

7. Daddy Long Legs are spiders. FALSE. A Daddy Long Legs isn’t a spider; although it is in the Arachnid family, it’s in a separate order from spiders. All spiders have two body segments—a thorax and an abdomen—but a Daddy Long Legs only has one round body part (and just two eyes, see #4).
8. Spider silk is always sticky. FALSE. Spiders can control the feel of the silk they produce—some is sticky, some is non-stick, some is thick and heavy, some is airy and light.
9. Scientists have identified all of the spider species. FALSE. There aren’t enough spider scientists! New spiders are being discovered all the time—in fact, our ecologist, Jim Steffen, found a sheet web-weaver last year that might be a new species! Ask him about it on World Environment Day.
10. There’s a spider 3 feet away from you right now. TRUE. But you’ll have to come to the Plant Science Center on World Environment Day to get the full story! See you June 1!

Leave No Plant Inside

Karen Z. —  April 1, 2013 — Leave a comment

Remember when plant-care experts suggested that talking to your plants could make them healthier? New studies indicate that WALKING plants will keep your plants extra healthy, extra happy, and extra green. Perhaps you thought that dog-walking was just for dogs?

At the Chicago Botanic Garden we’ve been walking our plants for years—it’s one of the little-known reasons for our lush foliage and gorgeous flowers. Crews are out at the break of dawn around the Garden walking plants before the crowds arrive.

“All it takes is a wheelbarrow and a little patience,” says horticulturist Heather Sherwood. “I’ve never had a plant refuse a morning walk—but make sure temperatures are above freezing, and even warmer for tropical plants, before you take them out.”

Garden horticulturists know that walking the mums to the garden bed improves their blossoms.

Despite the groundhog’s forecast on February 2, spring’s arriving late this year, and temperatures have remained too cold to walk all but the hardiest native plants. Consider taking advantage of this week’s warmer air to get housebound plants moving now.

“It’s important for plants to get out and moving early in the season,” says plant scientist Dr. Pat Herendeen. “Movement and exercise open the stomata (tiny holes in the leaves that allow gas exchange), letting fresh air into the leaves. It gets the plant breathing and the sugars flowing, which improves their overall condition and promotes healthy flowering.”

Dr. Jeremy Fant was among the first to take his plants for a stroll when the weather warmed up last week.

Health experts agree that a walk is good for you and your plants alike. For houseplant owners, there are plenty of plant-walking strategies. My neighbor combines the daily duties of dog walking with plant walking in a novel way. He saddles up his dog and attaches his smaller plants to the dog’s back. The two of them draw a lot of attention from other neighbors, and it’s easy to see why!

Enzo the dog doesn’t mind taking plants along on his regular walks.

If you don’t have a dog, you can carry your plants in a backpack, roll them in a wagon, or even pull them on a skateboard. Just getting them moving is the key. I don’t recommend recruiting your cat, however.

Remember for lush green happy plant results—keep those plants moving!

Make a Bird-Nesting Bag

Kathy J. —  March 16, 2013 — 1 Comment

Spring is here and the birds are returning from their winter homes. Some birds fly through the Chicago area to their nesting habitats up north, while others return and stay in the area.

Spring is the season for laying eggs, because it gives the juvenile birds all summer to mature and become strong before they need to migrate in the fall. Also, as spring turns to summer, the growing chicks require more food. The trees grow leaves, insects hatch, fruits ripen, and other food sources become more plentiful. The birds’ habits are perfectly synchronized with the seasons. 

At this time of year, recently returned birds will be looking for material to build a nest and lay eggs. You can provide some bling for a lucky bird family with a few things you have around your home.

You will need items including these:

  • A plastic netting or mesh bag, like the kind oranges and apples are sold in
  • Scraps of yarn or strips of fabric cut 1/4 inch wide and at least 6 inches long (longer is fine)
  • Optional — dryer lint, metallic thread, any other attractive loose materials

Let’s put this empty apple bag and some leftover fabric scraps to good use!

Put all of the scrap materials into the mesh bag. Tease out the ends of the material through the holes in the netting all around the bag so it looks like a bundle of loose stuff. Tie the top of the bag. Hang the bag securely on a tree branch where a bird can perch and pluck pieces of material from the bag.

Wall art or condo furnishings? Hang your bag outside and watch for birds!

Now you will be ready for International Migratory Bird Day, which is Saturday, May 11, this year. Watch the bag for signs that a bird is using the material. Look around your neighborhood for nests to see if any bird used the materials to build its nest. And have a happy bird day!

Let’s see where our fabric scraps end up this spring…

How to Train Your Plant II

Part 2: Using Light

Kathy J. —  March 8, 2013 — Leave a comment

Blog followers will remember that in the first “How to Train Your Plant” post, we demonstrated how plants respond to the gravitational pull of the earth. Geotropism is difficult to overcome, but that didn’t stop me from trying to make a plant grow sideways through a maze. You can try this activity at home.

You will need these items:

  • a shoebox (or any kind of box)
  • cardboard to make dividers
  • duct tape (or any opaque tape)
  • soaked bean seeds—I used different beans from a soup mix
  • a container with soil
PHOTO: The materials for the maze are displayed.

You’ll need a shoe box, cardboard dividers, seeds, a pot with soil medium, and of course scissors and tape for constructing the maze.

Stand the box on its side. Then cut two pieces of cardboard to fit in the box and make divisions. You’ll want these to fit as snugly as possible inside the box, but they don’t have to be perfect. The tape will fix that. Cut a large window in each divider. Cut a window on one end of the box. Tape the dividers in place as shown in the picture.

PHOTO: The maze assembly is shown in the shoebox. There are two dividers with cut out windows and a whole in the side of the box for light to shine sideways on the sprouting bean seeds.

Pardon the crude appearance of this maze. I wasn’t going for style points.

Plant the seeds in the soil and put the container on the side opposite of the hole you cut. Just for fun, I used several different seeds from a bean soup mix to see if one kind would get through the maze better than the others. It was like a bean-seed “race.” You can try whatever you like.

Make sure the holes in the divisions are big enough to allow lots of light in from the side, and don’t vary the height too much. Remember, we are fighting the plant’s tendency to grow up—if it’s too challenging, it won’t work. Trust me, I learned this the hard way.

When the maze is complete, give your beans a last bit of water, and maybe a kiss, and then close the box. Apply tape along the top edge, to secure it and reduce light. Then put it next to a window and wait.

And wait.

It’s going to take a few weeks. Remember, horticulturists are very patient. Open the box every few days or so to be sure it has not dried out. Add a little water, but only enough to moisten the soil if it is very dry.

When you see the bean plant emerging through the open window in the box, open it and take a look. How long this will take will depend on the kind of beans you use, how far the plant has to grow, and how warm the room is.  

The beans have sprouted and are moving toward the light

 It took my beans about five weeks to grow through the second window.

 

PHOTO: all of the bean sprouts are leaning toward the light.

The beans were definitely torn between growing up and growing in the direction of the light.

 

The winning sprouts, which I believe were lentils, did not actually make it through to the last window when I took this picture, and I’m not sure it has enough “umph” to do it. Still, notice how all of the plants leaned toward the light and most of them grew through the first window. That is a positive result!

What is going on here?

This activity demonstrates phototropism. Photo is the Latin word for “light,” and you will remember that a tropism refers to an organism’s response to stimulus, so that phototropism means plants grow toward the light.

It makes sense for plants to reach for the light because they need light to make sugars, their source of energy. Normally, growing up against the pull of gravity is also growing toward the light. In this activity, we changed that condition, forcing the beans to deviate from their normal course to get the light they needed.

The sprouts that grew the farthest and were closest to completing the maze had leggy stems that would not support growth upward to the last window. If I leave them a few more weeks, they could possibly grow along the bottom and then up the side of the box. I’ll have to wait and see.
