Allison Whitezell Teacher, Bonneville Elementary School, Utah While growing up, I loved school and learning. One of my favorite things to do was to read. I was able to experience so many things through books. I love being in charge and helping people, so I decided to become a teacher. Now, I have children of my own and I get to teach them too. Some of our favorite things to do together are playing outside and enjoying nature. We also love to read and visit new places.

Be a bird w ith a specialized beak!

Birds have beaks to help them get food. Experiment with different tools to represent different types of beaks to see which works best to pick up different types of food.

What you'll need:

Bird beak tools:

- Toby tweezers - two spoons - test tube or soda bottle caps - Blocky axils, twigs, or chopsticks - Various items to represent food for birds such as cereal, cut string, paper pieces, rice, seeds, beans, brads, pebbles, or marbles.

What you'll do: 1. Spread out a mix of “bird food” items for four bird beak groups.

Food items:

2. Join a bird group and get your “beak” tools.

3. Collect as much “food” as you can in 45 seconds with your tools.

4. Count and record the items you picked up in the Bird Beak Game data table.

5. Rotate groups and try again using a different “beak.”

2

Find small objects such as these around your classroom or home.

Bird Beak Groups Nuthatches Nuthatches use their beaks to feed on seeds.

Waxwings Waxwings use their short, thick beaks to feed on large berries.

Puffins Puffins use their short, strong beaks to grasp on tiny fish.

Herons Herons use their long beaks to grab large fish.

3

Question, investigate, and collect data When you have a great question, you can investigate to find an explanation. With an investigation investigation, you explore and make observations.

How does the shape of a bird’s beak affect its ability to pick up food?

Traits help organisms survive A trait is a special feature or behavior that an organism has such as the shape of a bird’s beak. Living organisms have traits that help them survive in the places they live. For example, camouflage is a trait that allows certain animals to blend into their surroundings, keeping them hidden from predators.

6

What advantage does camouflage give each of these animals?

Think, Pair, Share!

We get our traits from our parents An animal’s traits are inherited from its parents. This means that characteristics like fur color, size, and behaviors are passed down from parent to child. Inherited traits determine how an animal looks and acts.

A mother horse is called a mare and a baby is a foal. They look very similar.

Can you identify the similarities and differences between this mare and foal?

7

Plants have traits too Plants cannot move, which makes them at risk of being eaten, especially if they taste delicious to certain animals or insects.

So, how can a plant defend itself? Plants have traits that act as defenses such as thorns and spines that keep animals away.

Others taste bitter and some are poisonous.

Poison Oak (poisonous)

Death Nightshade (poisonous)

What advantage do these defense traits give each of these plants?

Foxglove

A specialized digestive system is a trait that allows this deer to get energy from tough, woody plants, such as weeds.

Thick, sticky sap is a trait that helps the pine tree not freeze during the cold winter.

12

Traits enable living things to thrive Different organisms look differently, act differently, and can do different things because of the traits they inherit. These traits help organisms live well in different habitats. A habitat is the environment that a plant or animal lives in.

L ooking like a bee keeps these flies safe Sometimes traits give organisms an advantage. Mimicry is a survival trait where one species evolves to look like another.

For example, hover flies resemble bees with their black and yellow stripes. Although hover flies are completely harmless, predators avoid them because they think they are bees.

This hover fly avoids being eaten by looking similar to a stinging bee.

The traits of a bee and a fly

You can tell the difference between a bee and a fly by some simple traits.

Honey bee

Traits of a bee:

Traits of a fly:

- Bees have long antennae.

- Flies have short, stubby antennae.

- Bees have hairy yellow and black stripes on their abdomen.

-Flies have less hair and different colored patterns on their body.

- Bees have two pairs of wings (four wings total).

14

House fly

- Flies only have one wing on each side (two wings total).

Is it a bee or a fly?

Bees and flies are different insects with distinct traits. Can you tell a bee apart from a fly by looking at their physical traits?

Feathers and Fur! Feathers and fur insulate animals by keeping cold air out and body heat in. They also keep animals dry and help them stay camouflaged. Look closely to see what makes feathers and fur good insulators.

What you'll need: - Toby tweezers - a petri dish - Meeka microscope or Maggie magnifying glass - samples of feathers or fur What you'll do: 1. Get some samples of feathers or fur. Your teacher may have some or you can go outside to look for some.

You could collect fur from a pet at home too.

2. Draw and describe what you see.

3. Use your observations to explain how each trait of the feathers or fur could be useful to the animal.

16

Oooh, this fur feels soft.

It looks interesting too.

Observe the insulative traits of fur Take a close look at these photos of a microscope’s view to see fur close-up.

How do you think these insulating materials help the animals survive?

40X magnification Buffalo Wool

Buffalo wool has crimped and twisted fibers that shed water and retain warmth even when wet.

Caribou have large, hollow hairs full of air, which helps insulate them from extreme cold.

They also have wool strands in their coat for extra warmth.

Some traits help individuals survive better Differences in traits among plants or animals of the same species can help them survive, find mates, and reproduce more successfully.

Some cats have better camouflage than others. Cats that are successful hunters may survive and have offspring.

These moths are members of the same species. The moth with better camouflage is more likely to stay hidden and survive to have offspring.

Tanuki Time Part 1:

Trouble in Shirakawa Try to read

It was a day like most others, but the animal residents of Shirakawa wanted something lucky to happen to them.

Read to me: It was a day like most others in the quiet Japanese village of Shirakawa.

Purple mountains loomed over thatched roofs and rice paddies. Lush green lotus ponds shimmered in the sunlight. Each house in the village had a garden statue of a raccoon-like dog called a tanuki. The village animals listened to folktales about takukis and carried around stuffed tanuki dolls because they thought they were lucky. All across the village, the mystical tanuki were celebrated, however, none of the village animals had ever seen a real live tanuki before.

What traits do the animals in this illustration have?

Try to read

They had been waiting to see a very important, lucky, and adorable animal called a Tanuki.

Read to me: Seeing a tanuki in real life meant luck and prosperity for years to come.

“Once, I saw a long snout,” said Sika the wetland deer. “As the animal scurried away, I saw its long, bushy tail too, but, it turned out to be a fox,” she said sadly.

“Don’t remind me,” said Serow, the forest goat, “Once, I thought I had heard the ‘yiy-yip’ sound of a tanuki and my heart raced. But alas, it was just the sound of a trotting horse.”

As the animals walked on, they heard a rustling in the leaves ahead.

Then, they heard the unmistakable call that was the stuff of legends.

‘Yip-yip!’ It was the barking sound of a real tanuki!

Would seeing a real tanuki bring prosperity their way today?

Do you think the ‘yip-yip’ sound of a tanuki is a learned behavior or an inherited trait?

An Adorable Baby Tanuki Try to read

They finally found a baby tanuki in the forest. It was a cute and it looked very sad and scared.

Read to me: The animals straightened up the best they could. They rearranged their whiskers, feathers, coats, and beards so they could impress whatever had made the sound. It was surely a tanuki—a celebrity with legendary status!

They wondered if they should bow or curtsy. Nobody knew, because they had never met a real Tanuki before.

They imagined how royal the tanuki would seem. But, when they finally saw what made the sound, they didn’t see a magnificent creature. Instead, they saw a very cute and very wide-eyed baby tanuki. With its glistening brown coat, button nose, tiny paws, and fuzzy belly, it was the most adorable thing they had ever seen!

Part 3:

What’s Wrong, Tanuki?

Try to read

The tanuki would not stop crying. The animals did not know what to do. Sika the deer thought they should feed it.

Read to me: Wise Serow went closer, followed by the other animals. “My dear Tanuki, you are here! Have you come to change our destinies and bring luck to the land?” he asked.

The animals held their breath, curious to see the wisdom the celebrated tanuki would share. Instead, the baby tanuki flopped over onto its stomach and started bawling.

Was the tanuki injured? Was it sick? Was it missing its family? Had it lost a valuable treasure? They almost forgot about the baby Tanuki as they debated each other’s ideas. They decided to take the tanuki back to the village.

“All this crying makes me hungry. Maybe our little tanuki is hungry too?” suggested Sika, the tiny forest deer.

37

Part 4:

Muddy’s Good Luck Roll

Try to read Muddy the coot used his webbed feet to swim and collect lotus root.

He made the tanuki a lucky rice roll.

Read to me: Since nobody had ever seen a tanuki, much less tried to feed one, they didn’t actually know what the tanuki would like to eat. They decided each animal would give the Tanuki the most special food they were able to gather.

Muddy the Eurasian coot went first. “With my wide, webbed feet, I can paddle through the water fast and walk in the mud very well.”

He made good luck rolls with a lotus root that he gathered from the pond.

The rolls were filled with rice and wrapped in seaweed. Muddy turned the tanuki to face exactly east where the sun rises and stuffed the lotus roll down its throat and into its grateful belly. Not a single grain of luck was lost. The animals were astounded and Muddy was pleased.

Kuchu the flying squirrel used her wing flaps to glide and search for fuki beans.

She gave the tanuki her lucky beans.

Read to me: “Dear Tanuki! If you liked that, just wait until you try my lucky food!” Kuchu, the giant flying squirrel, exclaimed.

Kuchu led Tanuki to a small patch of grass surrounded by branches. As if unveiling a masterpiece, he pushed some twigs aside and there, arranged as neatly as oranges in a grocery store, was Kuchu’s collection of lucky beans.

“It’s a bit of an obsession,” said Kuchu bashfully. “My wing flaps allow me to glide far and wide to search for beans and my cheek pouches help me carry them here.”

The tanuki began gobbling up the beans. Chomp, chomp! Munch, munch!

Tushi the mountain cat used her claws and teeth to catch his food. He gave the tanuki katsu chicken.

Read to me: “Now it’s time for you to try my favorite food!” said Tushi, the mountain cat.

Tanuki followed Tushi home.

“You’ve befriended a TANUKI and brought it home?” gasped Mama Cat. “Oh, the luck and prosperity this will bring! Please come in, Tanuki.”

The mountain cat family always had meat. “With our perfect eyesight and sharp claws,” beamed Mama cat, “we are good at hunting for our food.”

“Have some katsu,” she said as she served a thin piece of meat fried to a perfect golden crisp.

Crunch, crunch! Tanuki ate the katsu with a dark, sticky sauce.

“My strong arms make me an excellent climber. I can pick lots of fruits for you,” said the playful snow monkey. “Look at me! I can scamper and swing my way into lots of places!”

The monkey gave the tanuki his favorite lucky food—sticky green okra!

“I like okra because it’s slimy and fun to play with,” the monkey said, The tanuki took a bite of the sticky okra.

“There!” exclaimed the snow monkey. “Now that you’ve eaten a sticky food, you can do your best to stick to things until you finish them.”

Kawa the river otter used her strong tail to swim and catch fish. She gave the tanuki a delicious red tai fish.

Read to me: Kawa knew the other animals had impressed Tanuki, so it was time to bring her best paw forward.

“Oh great Tanuki, I’d be honored to offer you the luckiest food I know of—a delicious tai fish,” Kawa announced. “Tai fish are very fast, but I’m skilled at catching them!”

“I have a very strong tail,” said Kawa. I can swim fast, dive, and hold my breath as I search for the perfect fish.”

In a flash, Kawa slipped into the water. Tanuki tried to peer in wondering if he should follow, but soon Kawa was back. In her mouth was the special fish. Tanuki licked its lips and happily ate the entire lucky fish.

Part 9:

The Village Try to read Each animal could get special foods with their special abilities. The tanuki liked all the lucky foods that the animals gave him.

Read to me: Wise Serow asked Tanuki the question they’d all been most curious about: “Which food did you like best, dear Tanuki?”

The tanuki was so full it just leaned back and gave a little hiccup. It had liked all the lucky foods! In fact, this was one of Tanuki’s most important traits—not being a picky eater helps tanuki survive.

If there was one thing Tanuki knew for sure, it was that each of the amazing animals of Shirakawa-go had special talents and abilities. All it took for the animals to realize this was one poor baby tanuki that was grumpy because it had not had breakfast yet.

What type of trait describes the tanuki’s ability to like all kinds of food? Explain your reasoning.

A plant's surroundings affect its traits A plant’s traits can also be influenced by other factors in its surroundings such as availability of food and water. A fern growing in a dry place will not grow as well as a fern growing in moist soil even if they are the same type of fern.

This fern will stay smaller than others of its kind because it receives less water and has less soil in its rocky crevice.

These ferns grow large and healthy because they have good soil and lots of water.

How can the surroundings affect how these ferns grow?

An animal's surroundings affect its traits While the traits of an animal are inherited from its parents, other characteristics result from its surroundings. A coyote with little available food may look skinnier than a coyote with plenty of food.

This coyote is skinnier because it has less food in the desert.

This coyote grows large and healthy because it has lots of food in the forest.

How can the surroundings affect how these coyotes grow? How are the surroundings related to the traits of these coyotes?

Behavioral traits can be learned Many animals have unique behaviors and skills. Some behavioral traits are inherited but others are learned. Animals often learn these behaviors from other members of their species and by practicing.

Chimpanzees learn to use tools by observing other chimps. This chimp uses a stick to fish for termites.

Ospreys learn to catch fish with practice. A parent will feed its chick until it gets good at hunting too.

Dolphins learn to make dolphin sounds to communicate with others in their pod and to hunt as a group.

Mountain goats learn to navigate steep terrain by playing follow the leader with older goats.
