Camouflage

When I hike, I am always watching for animals, but many animals in the woodland ecosystem use camouflage as a defense mechanism, so it is not an easy task! Can you find the animals in the photos below?

My PreK students always enjoyed the camouflage game. After cutting-out lizards from colored construction paper, I placed the lizards on objects of identical colors to camouflage them. My young scientists wandered around the room trying to spot them. Click here to go to that post. During an evening lock-in, we did this activity in the dark, and the children used flashlights to find the animals. Play this game at home with any objects. Small stuffed animals, like Beanie Babies, are a great choice.

Why is the female duck camouflaged? She needs to protect her young from predators in her nest.

Click here for the Safeshare link. Listen for the different types of camouflage. Animals use color, patterns and mimicry. Do predators or prey use camouflage?

Why would a stagehand want to wear black and an umpire stripes? Sometimes we want to blend in and at other times stand out! Brainstorm other examples.

Camouflage

My PreK scientists began lab with a lesson about camouflage. Then we played a camouflage game in which they had to search for paper lizards around the science lab. We experienced how difficult it is to find an animal on an object that is the same color.



Play this game at home. Use camouflage to hide objects (Legos, stuffed animals, or small toys) around your home.

Can you find Luke, our tree frog?

We also met our new millipedes- Lily, Millie, and Jilly. See a previous post for more information about these interesting creatures!



I can always tell when PreK has left the room. 🙂

Do You See Me?

I love finding examples of camouflage which is used by both predators and their prey to hide from one another. In recent posts, we saw how a species used mimicry.

Most of us are familiar with concealing coloration when an animal matches its background, but this is an example of disruptive coloration. The striped pattern makes it difficult to identify the animal’s outline because it blends with similar markings on the decaying log. Zebras, tigers, and cheetahs also use this type of camouflage.

Gray Tree Frogs

This little gray tree frog has a big voice. After the spring peepers finish, the symphony of their voices fills the forest. One way to identify them is by the white patch under the eyes. They can change their color (gray, green, or brown) to match their surroundings or moods, and their blotchy appearance camouflages them in lichen.

Capturing Caterpillars

It has been my intention over the last month to capture photos of caterpillars, and August and September are the best months to do just that. I was rewarded with a cornucopia of finds! My daughter thinks I am a caterpillar whisperer.




Be cautious handling any caterpillar! Some can cause serious infections and rashes. Especially warn children not to handle fuzzy caterpillars with bristles. I believe this caterpillar is the venomous American dagger caterpillar. There are five projecting black barbs.

  • Caterpillars are the larval stage of butterflies and moths. This stage usually last two weeks to one month.
  • After spending their days eating and growing, a butterfly caterpillar will form a chrysalis and a moth caterpillar a cocoon. (Yes, they really are very hungry caterpillars!)
  • Six small eyes arranged in a semicircle are on each side of its head.
  • Well-developed jaws (mandibles) allow them to easily tear off leaves and chop them into small pieces.
  • Setae and antennae help the caterpillar sense its surroundings.
  • A caterpillar has six true legs on its thorax. Prolegs or false legs are on the abdomen and help them grasp objects.
  • As they grow and exoskeletons become too tight, they will molt.
  • Spiracles, breathing pores, are on each side of their bodies.
  • Caterpillars utilize camouflage, mimicry, venomous hairs, or a bright warning color to protect themselves from predators.

Order caterpillars through Insect Lore and watch them move through metamorphosis. “Just when the caterpillar thought the world was over, it became a butterfly.” A great reminder for us all!!

Copperheads

When I was on a woodland walk, a hiker warned me that a copperhead snake was crossing the path just ahead. Copperheads are a venomous (not poisonous) snake common in Georgia and other parts of the Southeastern United States. It is easily recognized by what appears to be chocolate kisses running along its body.

  • Copperheads are ovoviviparous which means that eggs develop within the mother’s body and babies are born alive in early fall. They are independent and venomous from birth.
  • Young have a tail with a bright yellow tip for about a year that attracts frogs and lizards.
  • This pit viper easily camouflages itself in leaf litter on the woodland forest floor.

  • Like other reptiles, copperheads are cold blooded, and their bodies are covered with scales.
  • Most adults grow to lengths of two to three feet.
  • These vertebrates have muscular bodies and are excellent climbers.
  • During the hot summer months, copperheads are nocturnal, but in the fall, they are active during daytime hours.
  • Copperhead bites are rarely fatal.

I saw these copperheads on a hike in North Carolina.

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.

Ghost Crabs

Have you seen these holes on the beach? They are perfectly round and are a variety of sizes. These burrows can be up to four feet deep and have angled entrances. Do you know what creates them?



GHOST CRABS!

These crustaceans are humorous to watch and move very quickly! They derive their name from their pale white color and provide a great example of camouflage because they can gradually change colors to match their surroundings. Ghost crabs are nocturnal, but occasionally make daytime appearances. Only one crab lives in each burrow.

Crabs have four pairs of legs and a pair of claws (decapods). One claw is larger than the other. They are invertebrates which means they have no bones, but their bodies are protected by an exoskeleton. They live near the water because they breathe oxygen through gills which must remain wet. Eyes are on stalks that swivel, and they will use their appendages to wipe sand from them.

I caught this one eating. They are omnivorous scavengers and help keep our beaches clean. (Remember not to use flashlights on the beach during the months turtles come on shore to lay their egggs.)

Females carry developing eggs under their bodies before releasing them into the water. Do you see the eggs under this crab?

Click here to watch full screen. I could watch these crabs for hours! Ghost crabs are evidence that God has a sense of humor.

Walk like a crab!

These cute crabs were made by former PreK students in Mrs. Lilge’s class. Make ghost crabs with white paint and mix a little sand into the beach color. Then add some claws.

New Phenomenon

I like beginning a science lesson or class with a phenomenon. Use them when you have a few extra minutes too. Click here for a list of phenomena to use with your scientists from NCSS. A reminder that a phenomenon is an observable event that fosters inquiry.

On my walk today, I spied a fawn. Why does she have a spotted coat, while her parents do not? Brainstorm answers. Encourage students to use their background knowledge on ecosystems and food chains. Look below the last photo for the answer.

Spots mimic patches of sunlight that shine through trees and other plants and thereby camouflage the fawn from predators. Click here for a previous post about camouflage.

Praying Mantis

I spied a praying mantis as I walked through my garden.

A praying mantis is a carnivore. The mantis will grab its prey with those front legs. Gardeners are a fan!

Do you know what is unique about the head of a praying mantis?

While in my lab, I purchased praying mantis egg cases each spring. Click here to see what happened! The life cycle of a mantis is incomplete metamorphosis – egg, nymph, and adult. Click here to learn more about the life cycle.

I went into my garden the next day and discovered the mantis was green. They are masters of camouflage! Click here for more information about these fascinating creatures!
