Feathers

Feathers are science treasures that catch my eye as I hike near the woodlands or stroll through my backyard. However, did you know that it is illegal (with a few exceptions) to collect feathers? Therefore, I capture their beauty in photos and leave them where I find them. Go here to read the law.

We think and communicate in words, so learning vocabulary is a critical component of any lesson when you teach young scientists. Use this opportunity to call attention to labels on a diagram. Note the downy feathers which keep the bird warm near the bottom of this contour feather. I purchased feathers for classroom use from Nasco.

For a previous post about how ducks waterproof their feathers, go here.

For a simple cutting activity that introduces symmetry, ask children to fold a piece of paper and draw half a feather from the top of the crease to the bottom. For my youngest scientists, I placed dots to indicate where to start and stop on the fold. After opening their feathers, students cut snips (barbs) along the feather edges.

Are Bugs Insects?

Are the words bug and insect synonyms? According to scientists, the two terms are not interchangeable. Let’s learn the difference between them. True bugs belong to the insect order Hemiptera.

The specialized piercing mouthparts bugs use for sucking is the primary difference between insects and bugs. Also, all bugs (and some insects) move through incomplete metamorphosis (egg, nymph, adult) during their life cycle, rather than complete metamorphosis (egg, larva, pupa, and adult). So, a bug is a type of insect. All bugs are insects, but not all insects are bugs.

The diversity in the world of bugs and insects is displayed through the accurate and colorful illustrations in the informational book, Bugs are Insects.

Bugs Are Insects by Anne Rockwell

Recently, I’ve come across several true bugs – cicadas and aphids. Stink bugs are also true bugs.

The sound of cicadas reminds me of hot Atlanta summers and their forgotten exoskeletons that cling to the trunks of trees. Go here for a previous post about cicadas and here for to learn more about a cicada killing wasp.

I discovered two species of aphids on my plants this summer, not a pest a gardener wants to find! I hoped the ladybugs I purchased, a natural predator, would eliminate them. Go here for a previous post about ladybugs. Neem oil, a naturally occurring pesticide, is another alternative to rid your plants of aphids.

The yellow oleander aphids, native to the Mediterranean, blanketed the top of my milkweed plants. I cut off the branch, and they have not returned.

Amazing Animal Bridges

Is the deer crossing the path or is the path crossing the forest?


Roadways fragment or isolate animal populations. They create barriers for animals to access food or mates, migrate, or reach nesting areas. The flow of energy through the ecosystem is altered. Many animals are also killed crossing roads every year. “Surveys conducted by the Humane Society and the Animal Protection Institute estimate that one million animals per day die on the road in the United States.” Read more here.

As a result of these concerns, engineers and scientists have collaborated to design and build innovative bridges and underpasses to help wildlife move safely across highways. Scientists ask questions and construct explanations based on evidence, while engineers define problems and design solutions.

Designing and building bridges is a common classroom STEM activity. The most meaningful engineering challenges are those that solve a real-world problem. Ask your students to research the wildlife that are threatened by crossing roads in the area in which you live, and then challenge them to design a bridge that would help that specific animal cross the highway safely.

Learn bridge building terminology here.

Add these books to your library to extend your children’s knowledge about the history of bridges and various bridge designs. Here to There and Me to You is an engaging book for you to introduce bridges to your students or children. Examples of architectural designs and real-life bridges are included. Use Google maps to locate these bridges. The overarching message is that bridges bring people together. Discuss real problems that the construction of a bridge has resolved.

Stripes

I’ve written other posts about patterns in nature, such as concentric circles, spirals and hearts. In this post, let’s focus on stripes. I’ve previously shared that I enjoy setting an intention for my walks, and finding stripes was an especially challenging task that has taken time. Both prey and predators use stripes for camouflage. Some of the stripes on shells and plants are growth rings or body segments while the stripes or layers on rocks result from heat and pressure.


Zebras, skunks, tigers, and raccoons are known for their stripes, but there are many other animals that have stripes too.

Merlin App

During my first education class in college, we visited the kindergarteners at the Model School on campus. The seasoned teacher was playing tapes of bird calls and her young students were identifying the recorded bird calls with amazing accuracy. With wisdom, she explained to this group of aspiring teachers that identifying bird calls improves auditory discrimination (subtle differences in sounds) which is a building block in phonics, reading, and writing.

The free Cornell Lab Merlin Bird app on my phone has quickly become a favorite. “Sound ID listens to the birds around you and shows real-time suggestions for who’s singing. Compare your recording to the songs and calls in Merlin to confirm what you heard. Sound ID works completely offline, so you can identify birds you hear no matter where you are.”  I’ve been surprised at how many birds are close by that I do not see. Go here to learn more about this app.

When you walk outside with your children and keep a list of the birds you hear. Add this app to classroom iPads and use it around your school campus.

I heard the following birds one morning as I savored a cup of coffee on my deck:

In this classic book, the owl tries to sleep, but the diurnal animals keep him awake. Young children will enjoy repeating the predictable text and laugh at the surprise ending. Use this book in a nocturnal unit and to introduce onomatopoeia, a word that phonetically imitates, resembles, or suggests the sound that it describes. It is a simple book to dramatize with instruments and bird calls. (Can you think of other sounds to add?)

So Many Engaging Color Activities!

As I mentioned in a previous post, I am intentionally capturing photos of summer colors.This post will highlight the primary colors, red, yellow, and blue and a sampling of my photographs follow. They are considered primary colors because they can’t be created by mixing other colors together. There are warm and cool variations of each color.






The primary colors mixed together create the secondary colors (orange, purple, and green), as well as the tertiary or intermediate colors. Four engaging investigations follow: Go here and here for a simple color mixing activity that introduces the concepts of hydrophilic and absorption.

Go here for a favorite color mixing exploration. Name the colors you create.

Green

Green is often the first color associated with summer. Don’t miss the variety of warm and cool hues. A warm green is closer to yellow, while a cool green approaches blue.





Give your child yellow and blue paint to mix and watch the science happen. Green is a secondary color because it is created from two primary colors. Add white to lighten (tint) the greens or a touch of black to darken them (shade). Red is across the color wheel from green and is therefore its complementary color. Mixed together they neutralize each other and create brown.

Go here to take a peek inside the book, Green, by Seeger.

The green pigment inside leaves is chlorophyll. Rub a leaf onto paper to see the pigment.

Test for the pigments inside leaves with chromatography.

Highlight green with a green day celebration! Have your children wear green and eat green food. Then go on a scavenger hunt to search for green living and nonliving things. How many different items can you find? Play I Spy with green items to develop vocabulary skills.

Urban Gardens

No matter where we each live, there is always room for a garden! Perhaps the greatest need is in those places where concrete and steel have replaced the natural landscape. These picture books feature urban gardens:

Summer Color

Celebrate summer! Using the following picture book as inspiration, search for natural items of each color that you identify with this season.

Capture photos and use them to create a book about color or a slideshow with or for children. Be sure to label the color and the object or include a repetitive sentence to build literary skills. Create a scavenger hunt and check off how many different items you find of each color.

Summer Color! - by Diana Murray (Hardcover), 1 of 2I like walking with intention and purpose. I’ve made a goal this summer to hunt for examples of each color and first up is orange. Often a color associated with fall, I was surprised at the number of orange pops in the summer landscape just waiting to be discovered. Now it’s your turn, how many orange items can you find – maybe a bird, stone, sunset, or shell? I tried to snap a photo of a chipmunk, but it was too fast!

All ages will enjoy mixing yellow and red paint (primary colors) to create orange (a secondary color), as well as the tertiary or intermediate colors which fall between them. Then add black and white paint to create shades and tints of orange. Blue is across the color wheel from orange and is known as its complementary color. Many sports teams wear complementary colors. Why? What happens when you mix blue and orange together?

Scientists describe their observations using physical traits, one of which is color. Color is also used to classify both living and nonliving things.

Such a great story about creativity! Use it to jumpstart an engineering activity in which students design and build 3D facades of their dream houses. Go here to view full screen.
