Hitchhikers in the Bathroom by Liana Mahoney

Imagine this. You step up to the sink, wet

your toothbrush, and begin cleaning your

pearly whites. Out of the corner of your eye,

you see something moving on the wall.

Suddenly, you realize you’re not alone in the

bathroom. Your heart pounding, you turn

toward the tiny intruder to get a better look.

You’re horrified to see that it has eight legs,

and a pair of oversized pincers on its front

end. Is it some kind of miniature octopus, or

a bizarre crab? Is it going to sting you?

Actually, it’s a bug, and it’s no more harmful

to you than a housefly. This tiny bathroom

bug is called a pseudoscorpion (SOO-doh-

SCOR-pee-uhn). But don’t be fooled by its

name. It’s not really a scorpion; it’s just a

relative. The pseudoscorpion is a kind of

arachnid (uh-RAK-nid), which means it is

closely related to spiders, scorpions, and

mites. Like scorpions, pseudoscorpions have

a segmented body and two enormous

pincers. But pseudoscorpions lack the

curved stinger that all true scorpions have.

Pseudoscorpions

usually live outside in

mulch, under tree

bark, and in leaf litter.

So how do they end

up in the bathroom?

They use those pincer-

like claws to hitch a

ride on other bugs,

such as flies and

beetles. When these insects come in, so do

the pseudoscorpions - attached to their legs!

These tiny arachnids prefer moist places.

Since the bathroom tends to be humid after

bathing and showering, it’s a likely place to

find them. But they are easily overlooked.

Most pseudoscorpions are only about two to

eight millimeters long.

Pseudoscorpions don’t bite or sting humans,

and they can even be helpful. These bugs

feed on common household pests, such as

carpet beetle larvae, ants, mites, and small

flies. Welcoming this hitchhiker into your

home may mean there are fewer household

pests to “bug” you!

Spitting to Surviveby Liana Mahoney

Spit keeps our mouths moist and softens our food

when we chew. Without spit in our mouths, we

would have a hard time talking. We would find it

even harder to swallow. But for some animals, spit

works better after it has left the mouth. Some

animals are experts at surviving because they are

expert spitters.

Llamas are animals often found in petting zoos and

farms. These animals seem to like their personal

space. A llama that feels threatened or annoyed will

spit slimy gobs at you to get you to leave it alone.

Sometimes llamas even spit on each other to steal

food! This trick usually works, because llama spit

includes food from the llama’s stomach, and it can

be quite smelly. When a llama spits on another

animal, the animal usually loses its appetite and

walks away, leaving its food behind.

The archer fish is a very skilled spitter. This fish is like a

submarine with a loaded weapon. It takes aim and

spits jets of water at insects and other small creatures

to knock them into the water. Then it gulps them

down quickly. To create such a forceful stream of

water, an archer fish closes its gills, and uses its

tongue to form a tube in its mouth. Then the fish

sticks its snout out of the water and aims. Aim!

Launch! Lunch!

Spitting cobras are also known for their expert aim.

These snakes spray poisonous venom from their fangs

to protect themselves. Scientists believe that these

snakes actually aim for the eyes! When the cobra’s

venom gets into the eyes of an animal, the venom

causes terrible pain, and even blindness. This gives

the snake plenty of time to get away.

Spitting is considered to be rude behavior in people.

But for some animals, spitting can be a smart way to

get lunch –or a clever way to avoid becoming

lunch!

Planet Earth is our home, but it is just a part of a larger group of celestial objects known

as a solar system. Our solar system consists of a star, the Sun, and everything else that

orbits it including planets, moons, asteroids, meteoroids, and comets. Our solar system

formed over 4.5 billion years ago and is located on the outer spiral Orion arm in the

Milky Way galaxy. The planets in our solar system can be divided into two groups which

are referred to as the inner planets and the outer planets.

The inner planets are the four planets located closest to the Sun. These planets are

smaller in size and have much smaller masses. The inner planets have rocky or solid

surfaces and are referred to as terrestrial planets. These planets are mostly made up of

heavy metals and have either no or few moons. The inner planets, from closest to

farthest from the Sun, are Mercury, Venus, Earth, and Mars.

Mercury is the closest planet to the Sun and it is even smaller than the Earth’s moon.

Its close proximity to the Sun makes it the fastest planet to orbit the Sun. Venus is the

second planet from the Sun and is very similar to Earth in terms of its materials and

size. Therefore, it is often referred to as “Earth’s twin” or “Earth’s sister.” Venus also

has the longest days of all the planets due to its extremely slow rotation. Earth is the

third planet from the Sun and has one natural satellite, the Moon. It contains a large

amount of water on its surface as well as in its atmosphere. It is also the only planet

where life is known to currently exist. Mars is the fourth planet from the Sun. It has

two moons and is referred to as the “red planet” due to the rusty color of its iron-rich

soil. Mars is covered in craters and volcanoes. The largest volcano is three times taller

than the highest mountain on Earth.

The outer planets are the four planets located farthest from the Sun. They are

separated from the inner planets by a region of space that contains billions of asteroids

and is known as an asteroid belt. The outer planets are larger in size and have much

larger masses. These planets are mainly composed of gases such as hydrogen and

helium and are referred to as gas giants. The outer planets all have dozens of moons

and each also has rings, although the rings of some appear very faint. The outer

planets, from closest to farthest from the Sun, are Jupiter, Saturn, Uranus, and Neptune.

Jupiter is the fifth planet from the Sun and is the first planet located beyond the asteroid

belt. Jupiter is the most massive planet in the solar system and has the shortest days of

all the planets due to its extremely fast rotation. It appears to have a giant red spot

which is actually a huge storm that has been swirling for hundreds of years. Saturn is

the sixth planet from the Sun and is most known for its clearly defined rings. Even

though Saturn is large in diameter, it is the least dense of all the planets in the solar

system. Uranus is the seventh planet from the Sun and it is unique because it is

extremely tilted and rotates on its side from top to bottom. Uranus was also the first

planet in the solar system to be discovered by the use of a telescope in 1781. The

eighth and final planet in our solar system is Neptune. It is located farthest from the

Sun and takes 165 years to orbit the Sun one time. Neptune is nearly four times the

size of Earth and has the most violent winds of all the planets in the solar system.

Gravity governs the motion of all objects throughout the universe. Gravity is the force

that pulls all objects with mass toward one another. The greater the mass of an object,

the greater amount of gravitational force the object has. In our solar system, the inner

planets tend to have less gravitational force because they have smaller masses. The

outer planets have a greater gravitational force which explains why each has dozens of

moons in orbit around them. In our solar system, the Sun has the greatest mass of any

object. Therefore, the Sun has the most gravitational force which explains why the

planets revolve around it.

When studying the solar system, it is also important to understand the difference

between mass and weight. Mass is the amount of matter in an object. An object’s

mass does not change from one location to another. For example, an object’s mass on

Earth will be exactly the same as the mass of the same object if placed on another

planet. However, an object’s weight can change from one location to another. Weight

is a measure of the force that gravity exerts on an object. The greater the gravitational

force, the greater the weight of an object. For example, Jupiter has more mass than the

Earth and has a greater gravitational force. Therefore, an object’s weight on Jupiter

would be much greater than the same object here on Earth.

Even though astronomers have gathered a large amount of data on the objects that

make up our solar system, there is still so much more to discover. The distances

between the planets are extremely large and it can take years to collect pictures and

other information from these regions of our solar system. Astronomers continue to

study the components of our solar system to better understand the formation of the

“neighborhood” in which the Earth belongs.

Ferdinand Magellanby Kelly Hashway

When we think of explorers, one of the first names that

comes to mind is Christopher Columbus. But there are many

other explorers who did great things, one being Ferdinand

Magellan. Magellan was a Portuguese sailor who proved it was

possible to sail around the globe.

In 1492, Christopher Columbus had sailed west trying to

reach the Indies in hopes that Spain would be able to trade with

Asian kingdoms on the other side of the world. But as you know,

Columbus discovered America and never really made it to the Indies.

Later, eastern routes to the Far East were discovered, but Spain wanted to find a quicker

route by water. So in 1519, Ferdinand Magellan set sail from Seville, Spain under the rule of King

Charles I. His goal was to discover a westward route to the Spice Islands in Indonesia. The Spice

Islands were named for the spices produced there, which were in great demand in Europe.

Magellan took five ships and approximately 270 men with him on his expedition. During

the trip, Magellan explored the eastern coast of South America, looking for a water passage

through the continent. He discovered a body of water that cut through the southern tip of

South America, connecting the Atlantic Ocean and Pacific Ocean. This body of water was

named the Strait of Magellan.

The journey wasn’t an easy one for Magellan or his men. The rough waters caused one of

the five ships to be separated from the others and eventually return to Spain. Another ship



crashed into a rocky island. With only three ships left, Magellan continued for months, making it

to the Philippines. Here, Magellan was killed during a religious dispute with a local tribal king on

the island of Mactan. This was later called the Battle of Mactan.

The remaining crew members were led by Juan Sebastián Elcano. Because there

weren't enough men to sail all three ships, Elcano ordered the men to burn one of the

remaining ships. They then sailed two ships to the Maluku Islands, better known as the Spice

Islands. There they loaded up on valuable spices before attempting to return to Spain.

Near the end of the voyage one of the two remaining ships was captured by the

Portugese and wrecked in a storm. In 1522, three years after the expedition began, Elcano

returned to Spain with only 17 crew members and only one of Magellan's five ships.

While the voyage cost the lives of many men, it was important to our history. Magellan

was the first European explorer to sail from the Atlantic Ocean to the Pacific, and he was also

the first to cross the Pacific Ocean. But more than that, Ferdinand Magellan proved that a ship

could sail around the globe.
