Looking for Lunch

It’s another busy day in the ocean All the sea animals are hungry

A parrotfish eats the soft part of a coral as it swims around The energy from the food passes from the coral to the fish It keeps the parrotfish alive, but not for long! A much larger blacktip reef shark swims by and sees the parrotfish It moves closer Its sharp teeth cut the parrotfish Gulp! Energy moves up another link in the food chain The energy that was in the parrotfish is now in the shark And that shark or some other fish may end up on your plate for lunch!

Sea creatures—like people—eat more than one thing And many of these animals fight for the same food All of the animals and the food they eat connect to form a “food web.” In this web of life, energy moves from animal to animal We are-all connected to the ocean

Check T for True and F for False

1 Sea animals get energy when they eat other animals 2 Energy moves from strong animals to weak animals 3 A shark does not get energy from eating a small fish

Paragraphs of Contrast

In a paragraph of contrast, you write about the differences between two things You can use facts and descriptive words to show differences

You can also use words that show contrast, such as but and however, and

expressions such as in contrast

® Read Read about land turtles and sea turtles How does the writer Show differences? Underline the words and expressions

Land and Sea Turtles

All turtles begin their lives on land However, baby turtles lives are very different Baby land turtles crawl away

to live in woods, swamps, grasslands, or

deserts In contrast, baby sea turtles

crawl to the ocean to live in the water

Land turtles and sea turtles look different,

too Land turtles have hard, round shells

When they are afraid, they hide in their shells Sea turtles, however, have soft, fiat

shells They can't hide inside them, but

they can swim away really fast When cold weather comes, land turtles dig holes

in the ground and sleep all winter They

are too slow to move to warmer places

In contrast, sea turtles simply swim away sea turtle

to find warmer waters

® Write in your notebook Write about dolphins and sharks How are they different? Use words and expressions that show contrast

Trains Make the | {iris

World Go ‘Round ` circle the earth 30,000 times Stand back! The Shinkansen, or “bullet train,” is coming into the station! These

Japanese trains are some of the fastest trains in the world The journey from Tokyo to Nagano used to take three hours The bullet train travels at 300 kilometers per hour (186

miles per hour) and takes only 79 minutes! The trains are always on time (although once

one was 42 seconds late!), they’re comfortable, and they’re very quiet You feel like you aren’t moving at all But don’t fall asleep There is a lot to see The bullet train travels across 300 bridges, and you can see Mount Fuji out the window

In fact, trains are popular in many parts of the world—not just Japan Every day, billions of people in China, India, and Europe travel by train Trains are the fastest and safest way to travel on land (Cars and buses are much more dangerous.) Although trains are more expensive than they used to be, they still make the world go ‘round!

A Good Idea

In my opinion, sticky notes are a great yse my ‹ se

invention Theyre a really good idea and (magi =

they're easy to use You lift the paper off, write a note, and stick it on your notebook or

on your computer And they come off easily a

I think most people like them because they COG

are so useful Before I started to use sticky / h Ve ht ;

notes, I used to forget everything!

I believe that the story of sticky notes O

is interesting, too Sticky notes have two inventors Spencer Silver invented the glue in 1970 The glue wasn't very strong, so he

didn't Know how he could use it! Four years later, Arthur Fry found a way to use the glue One day, all his notes fell on the floor He wasn’t happy! But he remembered Silver's glue! Later, he used the glue on small pieces of paper It worked! The notes stayed on the paper, and it was easy to remove them And now we have a cool—and useful-——invention!

Video Games:

Then and Now

In the late 1950s, a scientist invented the first

video game It was a simple table tennis game It wasn’t until the 1970s that video games became popular Gamers used to pay to play games that

were short and slow They had to go to video arcades, which were large rooms full of machines This changed in 1972 with the invention of the first home video game Gamers could finally play at home! Soon, people wanted to play outside the home, too The first successful handheld game came out in 1989 After that, people could play games almost everywhere

The invention of the Internet in the mid-1990s changed gaming forever Thanks to the Internet, multiplayer games became very popular Gamers could compete online against people all over the world! Then came the modern game consoles in the late

1990s Suddenly, video games became popular with everyone For the first time, people saw video games as more than a hobby It was a way to learn or become healthy Even schools and hospitals began to use them! What’s next?

1 The interest in video games began in the 1970s

2 Arcades were large rooms where you could play soccer games 3 People wanted to be able to play video games everywhere

of Skateboarding

Skateboards are much more than just four wheels and a piece of wood There are three

important parts of the skateboard: the deck, the truck, and the wheels

The deck is the board It is usually made of strong wood that can also bend Skateboard

decks have curves at the “nose” (the front) and the “tail” (the back) After you push and

the wheels start turning, you should put your feet near the curves They help you balance The truck, connected to the wheels and the deck, helps you control the direction When you lean right, the truck makes the deck turn right When you lean left, the skateboard

turns left What about the wheels? The wheels move the board forward and backward They also control the speed

If you want to have fun, check that all three parts work before you go skateboarding And don’t forget your helmet, knee pads, and elbow pads!

ball so that it turns around and around

the pole! Tetherball looks easy, but it

isn't Every time I hit the ball, it flew

up in a big circle So it was easy for my brother to hit it! My brother is

better than I am First he hit the ball, and then he pushed it with his hands When he hit the ball, it went around the pole As a result, he won every

game! I want to play again soon, but not with my brother!
