Reptiles By Science 4 Kids

Reptiles are cold-blooded, which means that their bodies react to the temperature of their surroundings. They are covered in scales of various types and sizes. When they are born, they are on their own, without their parents, but fortunately, they can rely on a strong instinct!

Turtles are equipped with a cartilaginous shell that works like a shield. Turtles may live underwater or on land. Turtles are ancient creatures. They are believed to have existed between 251 million and 199 million years ago. Most of them are highly endangered because of hunting (for food and traditional medicine) and pollution.

In paragraph 1, the details about young reptiles support the idea that newborn reptiles -

• are in need of protection

• need their parents

• can survive on their own

• live in groups

The Real Story About Sharks

Sharks now face a new enemy, mankind. Sharks have evolved and survived millions of years, but will they be able to adapt quickly enough to survive their new enemy? It is estimated that over 100 million sharks are killed each year by commercial and recreational fishing. An additional threat sharks face is the altering of their habitat by pollution. Like many animals all over the world, the growth in human population rapidly changed a once stable ecosystem.

These popular and iconic creatures are everywhere, on our TVs, in movies, and featured in social media. Even with their popularity, resilience, and evolution, sharks have become endangered species. Only time will tell if they will adapt and survive alongside mankind.

To Visit Mars or Not

Humans are eager to explore Mars. However, there are dozens of

problems that need to be solved before humans can safely land there

and live successfully. Just one of the many problems centers around

dust. Mars is known to have the largest dust storms of any planet in

our solar system. The dust grains are so tiny that they are unlike

anything we have here on Earth. Scientists fear that the Mars dust

could clog machinery, making them inoperable. To make matters

worse, Martian dust is thought to be toxic. As the Mars rover,

Curiosity, conducts soil experiments on the planet, scientists are

learning that Martian soil is full of chemicals dangerous to humans.

Fortunately, scientists are working on a solution to the dust

problem. A company called Paragon Space Development, which

specializes in making life-support systems for space, is working to

develop seals that will keep the dust out. Their engineers are doing

extensive testing and experimentation to make sure these seals will

work to protect humans and machines.

How does the structure of the passage best help the reader understand our concerns with visiting Mars?

• By comparing and contrasting life on Mars with life on Earth

• By describing the events in order that have occurred on Mars

• By listing the problems we face with exploring Mars and ways we are trying to solve them

• By giving the causes and effects of the dust storms on Mars
