Celebrating Wildflowers and Miss Lady Bird Johnson

We are pleased to be hosting STEM Friday this week, a celebration of Science, Technology, Engineering and Math books for children. The theme for today is wildflowers, so be sure to click through the link and check it out. (This post contains affiliate links to Amazon).

We are fast approaching the the centennial of Lady Bird Johnson’s birth, December 22, 2012, and it seemed like a perfect time to pull out Miss Lady Bird’s Wildflowers: How a First Lady Changed America
by Kathi Appelt and illustrated by Joy Fisher Hein. This is a beautiful picture book biography that overflows with the beautiful wildflowers that Lady Bird Johnson enjoyed so much. (For a full review of the book, see our sister blog, Wrapped in Foil.)

You may wonder how a picture book about a former first lady who loved wildflowers could be used as a jumping off point for STEM. Here are just a few ideas:

Science:

– use the website and the guide in the backmatter of the book to identify all the lovely wildflowers in the illustrations

  • Seed dispersal
  • Ecology issues, such as how introduced and invasive plants change an area
  • Food webs
  • Weather and climate, and how that effects plants

Technology:

  • Use a computer program to design a wildflower garden
  • Construct two weather stations and compare the weather in a wildflower garden versus a parking lot

Engineering:

Wildflower seeds come in many different sizes and shapes. Investigate how wildflower seeds are planted, harvested, processed or threshed, and packaged for sale. Can you think of a machine to do this in a better way?

Math:

Investigating wildflowers can be a wonderful way to promote all aspects of STEM.

Lupine life cycle

Let’s take a look at the life cycle of one of Lady Bird Johnson’s favorite flowers, the bluebonnet or lupine. Her favorite was Lupinus texensis, the Texas bluebonnet. We are showing the arroyo lupine, Lupinus succulentus, which is a similar plant.

Lupine seeds

sprout into seedlings. The first two smooth oval “leaves” are actually the cotyledons.

Soon the regular leaves emerge and the plants begin to grow.

In a few short months the lupines begin to flower.

Honey bees and other pollinators pollinate the flowers. When the flower has been pollinated, the white part turns red.

Now the petals fall off and the seed pods begin to form. You can see the dark green seeds forming inside.

When they are mature, the pods turn brown. Do you see the ones towards the bottom of the photograph that are twisted? The pods burst open when they are mature and send the seeds shooting through the air. Hopefully, the seeds will land in a good location and grow into new lupines the following year.

Plant some wildflowers so you can follow your own plant life cycles. In the Sonoran Desert the time to plant wildflowers flowers for a spring bloom is right now (November).

For the Birds: The Cornell Lab of Ornithology

A few weeks ago our family got to visit the Cornell Lab of Ornithology in Ithaca, New York.

It’s a fun place to go to if you ever get a chance, especially if you are a bird lover or you enjoy nature.

That’s the main building across the water.

There are trails through the woods.

The trails can be wet in the spring, but they are well-maintained.

Of course, there are plenty of birds to observe. At the main building, the staff provides bird feeders so you can watch birds at any time of day.

Surprisingly, although they are known mostly for studying birds, the scientists at the lab also study a variety of other animals. Because they have pioneered sound recording of animals and now filming animal behavior, you will also find information about animals as diverse as frogs and whales. This promotional video gives you an idea of the variety of topics studied.

Although the video is quite loud and dynamic, we actually found our visit to be quiet and soothing.

Our final stop was to the gift shop. They carry a number of great nature books, including the exciting new children’s books about birds listed below. You might want pick up some of these books and read them to help get prepared for the trip. 🙂

See what Susan Stockdale has to say about her book at STEM Friday.

Even if you can’t go in person, the Cornell Lab of Ornithology has a number of education and citizen scientist projects you can participate in no matter where you live. The Lab partners with other institutions for the Great Backyard Bird Count, which is a very child-friendly event. The next count is going to be Feb. 15-18, 2013, so be sure to put it on your calendar. (A previous post about the Great Backyard Bird Count with related activities).

Have you ever visited the Lab of Ornithology? If you go, we’d love to hear about your trip.

Edit: Archimedes Notebook has a wonderful interview with young Olivia Bouler, who wrote and illustrated Olivia’s Birds, about her book and her recent visit to the Lab of Ornithology.

Awesome Snake Science!

Do you know what an ophiologist is? After you read today’s featured book, Awesome Snake Science! 40 Activities for Learning About Snakes by Cindy Blobaum, you might want to become one yourself!

What is an ophiologist? As you probably have guessed, unlike a herpetologist, who studies amphibians and reptiles, an ophiologist is a person who specializes in the study of snakes.

Why would anyone study snakes?  Snakes are fascinating (yet also sometimes feared creatures) that deserve further study. They can be important predators of pests like mice, rats, insects and slugs. Researchers are finding new medical uses for snake venom. Understanding snakes helps keep people safe from the venomous ones. Studying snakes helps us understand our natural world. The list goes on and on.

Do you need live snakes to do the activities from this book? No, Blobaum has created scientifically-relevant activities that can be done with items from around the home, although they beg to be supplemented by a trip to a zoo to see some live specimens. For example, learning how to estimate the length of a snake lying on the ground is something snake scientists must do in the field quickly and accurately. In Blobaum’s “Snake Survey” activity, snake stand-ins like lengths of yarn and belts to help children learn the estimating, measuring and data-collecting skills that can definitely be applied in the real world.

Other activities sure to appeal to children include making foldable fangs, creating a model of snakes’ eyes, investigating snake venom using an enzyme found in pineapple, and creating a bad odor to mimic snake defensive compounds. These are fabulous for the young hands-on learner.

Although I only have highest praise for the text in the book, I should mention that the photographs used to illustrate the activities are not printed in color like the vibrant cover. Some of the photographs are too dark to be really effective. It was probably done to reduce printing costs, which is unfortunate because the rest of the book is so good.

Awesome Snake Science! is an amazing book that sets a new standard for how hands-on science should be done. It is sure to appeal to budding scientists, particularly those interested in becoming ophiologists. 🙂

Our own learning adventures, inspired by the book:

Snake Identification Activity

Snakes can be hard to identify because you often only catch a glimpse of one slithering by, because many species are camouflaged, or because they may mimic other species that are well-defended. The good news is that these days there are Internet sites and even apps to help with snake identification.

Let’s figure out which of the following photographs is of a Sonoran gopher snake, a desert king snake and a desert blind snake using the Discover Life snake identification guide.

First of all, these snakes are all from western North America (Arizona to be exact).

A.

Make a guess which of the three snakes this might be.

Click on the Discover Life snake identification guide. Select the following choices (I provided the choices because they may not be visible in the photograph. Feel free to modify them.)

1. Body bottom color: other

2. Body bottom pattern: solid

3. Body color: solid

4. Scales:  smooth

5. Divided? don’t check box

6. Range:  North American West

Now hit one of the “search” buttons on the far right side

You should see matches come up in the column on the left side. Click on your guess for which snake it is (hopefully it will be in the list) and check the photographs to see if it matches. If not, try one of the other names. Remember, snakes can vary a lot in color, so look other characteristics, too.

B.

Click in the top menu to “restart”

Which snake is this?

1. Body bottom color: other

2. Body bottom pattern: blotches

3. Body color: spots

4. Scales:  smooth

5. Divided? don’t check box

6. Range:  North American West

This time only one of the names will probably come up in the list on the left. See if this snake matches.

C.

If all went well, there’s only one name left. Let’s see what kind of snake this is.

Characteristics:

1. Body bottom color: white

2. Body bottom pattern: solid color

3. Body color: spots

4. Scales:  keeled strongly

5. Divided? don’t check box

6. Range:  North American West

Skip all the rattlesnakes, because it doesn’t have a rattle on its tail.
