Informational Text Structure

1. Dinosaurs existed about 250 million years ago to 65 million years ago. This era is broken up into three periods known as the Triassic, Jurassic and Cretaceous periods. The Triassic Period lasted for 35 million years from 250-205 million years ago. Planet Earth was a very different place back then. All the continents were united to form one huge land mass known as Pangaea. The Jurassic Period was the second phase. The continents began shifting apart. The time scale for this famous period is from 205 to 138 million years ago. The Cretaceous Period was the last period of the dinosaurs. It spanned a time from 138 million to about 65 million years ago. In this period the continents fully separated. However, Australia and Antarctica were still united.

The Cretaceous Period was filled with dangerous predators, but two of the most feared hunters were the tyrannosaurs rex and the velociraptor. The tyrannosaurs rex was one of the largest carnivores to ever walk the Earth. He was 20 feet tall and weighed seven tons. His jaws could crush down with 3,000 lbs. of force, enough to smash the bones of his prey. The velociraptor was very small compared to rex. Raptors only stood three feet tall and were seven feet long, weighing merely 35 pounds. But the velociraptor was fast. Scientists think that raptors could run 24 miles per hour and turn on a dime. Both dinosaurs used their jaws to kill prey, but the raptor had a secret weapon: a retractable toe claw that he pulled out like a knife to slash at his prey. Both dinosaurs had eyes on the front of their heads, which helped them track prey. If these two dinosaurs had fought, it would be difficult to say which would win; however since raptors died over ten million years before the first tyrannosaurs was born, scientists don’t believe such a fight ever occurred.

Creating a Dinosaur Sculpture

Materials: pipe cleaners, clay, non-toxic paint

Wouldn’t you like a scary dinosaur model on your desk to protect your pencils and textbooks? You can easily make one by following these simple directions. First, bend your pipe cleaner to make the frame of your dinosaur. I suggest you create a tyrannosaurus frame by using one long pipe cleaner as his neck, spine, and tail, and then bend another into a u-shape to make his feet. Wrap the feet around the spine piece. Next, roll out clay to wrap around the pipe cleaners. Let the clay dry overnight. The next day you may want to paint your dinosaur using non-toxic paint. His eyes should be white, but feel free to color your dinosaur as you wish. Nobody really knows how dinosaurs were colored, so don’t let anyone tell you that your dinosaur can’t be pink. Lastly, put him on your desk and watch as he or she scares away bullies and pencil thieves.

What Happened to the Dinosaurs?

There are many theories about why the dinosaurs vanished from the planet. One theory that many people believe is that a gigantic meteorite smashed into the Earth. Scientists believe that the meteorite was very big and that the impact may have produced a large dust cloud that covered the Earth for many years. The dust cloud may have caused plants to not receive sunlight and the large plant eaters, or herbivores, may have died off, followed by the large meat eaters, or carnivores. This theory may or may not be true, but it is one explanation as to why these giant reptiles no longer inhabit the Earth

One day Dino the Dinosaur decided to go for a walk to the watering hole. It was a sunny day and the sky was blue and clear. Dino was thinking about his girlfriend Dina when he saw a pack of wild lizards and animals running through the plains in a frenzy. Dino tried to ask the critters why they were running, but they just kept running. Dino scratched his dinosaur head and continued walking toward the watering hole. Soon after, Dino heard a loud thumping noise like the slow beat of a drum. The earth shook and fruit fell from the trees, but Dino was so deep in thought over his girl Dina that he didn’t even notice. The thumping grew louder and louder as Timmy the Tyrannosaurs Rex approached Dino. Dino kept thinking about his girl Dina until the moment Timmy ate him.

The surface of the Earth is divided into pieces called “tectonic plates.” These plates move. When the plates rub against each other, they do not move smoothly. When the plates do not move smoothly, earthquakes result. Some parts of the world get more earthquakes than other parts. The parts of the earth that get most earthquakes are near the edges of these plates.

Some countries, such as Japan, or parts of a country, like California in the United States, have a lot of earthquakes. In these places it is a good practice to build houses and other buildings so they will not collapse when there is an earthquake. This is called seismic design or "earthquake-proofing".

Have you ever wondered what the inside of a volcano looks like? Deep underground is a magma chamber. The magma chamber is under the bedrock of the earth’s crust. The conduit or pipe runs from the magma chamber to the top of the volcano. The conduit connects the magma chamber to the surface. Most volcanoes also have a crater at the top. Volcanoes are quite a sight, and you can enjoy this site all over the universe. Volcanoes are found on planets other than Earth, like the Olympus Mons on Mars.

Most people have had red pizza, or pizza covered with red sauce, but have you ever had white pizza? White pizza is made in almost the same way as red pizza: the dough rises and is rolled out, toppings are applied, and it is cooked in an oven—but the key difference is that white pizza does not have any tomato sauce on it. Instead, a white pizza may have olive oil or no sauce at all. I like white pizza more than red pizza because you can really taste the ingredients. Adding some fresh tomatoes to a white pizza will give it that tomato flavor without the completely overwhelming taste of the red sauce that covers most pizzas. If you have not had a white pizza, I recommend that you order or make one today.

Pizza is so old that its origins are not quite clear to historians, but the word pizza comes from the Latin verb pinsere, meaning to press. It may also be related to the Greek word pitta. In any event the word “pizza” was first documented in Italy in 997 AD. Whatever they were eating back then, however, was quite different from the pizza that we know today. Pizza as we know it could not really have been invented until sometime during the 16th century, when tomatoes were brought to Europe from America. This was big, but in my opinion the greatest development in the history of pizza occurred in 1905, when pizza was first sold in America. The rest, as they say, is history.
