Your circulatory system is responsible for moving blood all through your body. The major parts of your circulatory system are your heart, blood, and blood vessels. The heart is the second most important organ in your body (next to the brain, of course!) It is about the size of your fist. Its function is to pump blood through your blood vessels. There are four parts, or chambers, in your heart that each perform a specific function. Blood from all parts of your body enter the right side of your heart. That blood is pumped out of your heart to the lungs to pick up oxygen. Once it's gotten the oxygen from your lungs, it reenters on the left side. Then the oxygen-rich blood can travel back to your body to be used. The cycle repeats over and over.

Did you know that blood with no oxygen is actually blue? So why don't we bleed blue? As soon as the blood hits the air, it gets oxygen, of course, and turns red!

Blood is made up of both solid and liquid parts. The solid parts include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen, white fight germs that cause disease, and platelets plug holes in blood vessels when we are injured. A “bruise” is actually just a pool of blood under the skin that is being stopped up by platelets. Your blood carries oxygen from your lungs to all your cells. Blood also carries nutrients from your digestive system to the cells so they can function. Your blood also works to pick up the waste that your cells produce. It carries the waste to other organs, like the lungs and kidneys, that help the waste leave the body.

Blood vessels are the tubes that carry the blood. There are two main types of these tubes: arteries and veins. The arteries nearest the heart are very large. They get smaller as they branch out to different parts of the body. They are connected to veins, which carry blood back to the heart. An easy way to remember the difference is: “Arteries carry blood Away.” When too much waste from eating unhealthy food piles up in the blood vessels, the blood cannot move through them. Then the heart cannot keep doing its job. Eating healthy foods helps clean the blood vessels. What heart-healthy foods have you eaten today?

Words to know: circulatory system: the system that moves blood in your body blood: liquid-like matter that flows through our bodies, delivering oxygen and nutrients blood vessels: carry the blood in the body heart: the organ that pumps blood to the blood vessels artery: carries blood away from the heart vein (VAYN): carry blood to the heart for oxygen

Rock Cycle – Earth & Space Science (WS#5S35)



Page 1 of 2

Name: Date:

The sun was beating down on Edgar and his grandfather

as they went from row to row of the garden, removing the

many rocks that lay there.

“I found another one!” cried Edgar as he heaved the rock

over the fence.

“Good job, Eddie!” said Grandpa, smiling.

“Now that we get these rocks off the seeds, they can

grow better, right?”

Grandpa nodded. “Of course! Then we can make a delicious vegetable soup.”

Rocks are a combination of one or more minerals found within Earth’s crust.

These small parts are made from iron, carbon, silver, etc. There are three major

types of rocks. Each of these types is formed differently in the earth. The

process that forms rocks happens over and over again and takes many years.

All rocks are formed deep within the Earth. Igneous rocks are rocks that

are formed when magma from Earth’s core reaches the surface. There, it cools

and hardens into rock. Can you think of a place you would find lots of igneous

rock? Near a volcano would be a good place to start!

Over time, all rocks break down at Earth’s surface. Sand is an example of

how rocks can break down into tiny pieces. But over 200 million years, if enough

sand layers are pressed together, a rock forms. We call this type of rock

sedimentary rock. It can also be formed on the bottom of the oceans, in lakes,

and rivers.

Have you ever heard of the Mighty Morphing Power Rangers? Morph means

“to change forms” and that’s exactly what metamorphic rocks do. They are

igneous or sedimentary rocks that have been changed by heat, pressure, or both.

They can make beautiful, colorful minerals appear. We use metamorphic rocks in

our homes to decorate. Marble and slate are both metamorphic rocks.

Gold and silver are both metals that are found within rocks. These minerals,

along with platinum, are used today in coins and jewelry. They are valued because

they are rare, beautiful, and they can be worn or used on a daily basis without

breaking. Many rocks and minerals were used in the past in cities like Cairo, Egypt

for trading, decorating, and even writing! They would melt the gold and dip their

pens in it to write.

Whether igneous, sedimentary, or metamorphic, people have been using

rocks for building since the earliest days of man. Rocks might not be the most

interesting subjects in science, but if you look around you, you’ll see we use rocks

more than you might think.

Words to know:

minerals: natural Earth substance gotten by mining

igneous: rock formed when magma cools

sedimentary: rock formed due to pressure of layers of sediment

metamorphic: rock formed when other rocks are heated or under pressure

valuable: having lots of value for a person or group

Try This! Make your own crayon rocks.

You will need:

! crayons and crayon sharpener

! 2 pieces of board

! candle

! safety goggles or glasses

! aluminum foil

! hammer

! clothespin

Procedure:

1. Cut 2 pieces of aluminum foil about 20cm x 10cm. Lay one inside the other for double

thickness.

2. Sharpen crayons to get lots of shavings. This is your “sediment.”

3. Place crayon sediment inside foil and fold edges in.

4. Place aluminum foil packet between the boards and press down on the boards with your

hands to flatten the shavings.

5. Open the foil and examine your crayon sediment. Record what you observe under

“Conclusions #1.”

6. Rewrap the crayon rock and place it under the boards again. This time, use a hammer to

hit the top board and make more pressure. Examine your crayon rock again and record

what you observe under “Conclusions #2.”

7. Rewrap the crayon rock and hold the packet over a candle with a clothespin. *Remember:

Safety First! When dealing with fire!*

8. Heat your rock for one minute. Let it cool, unwrap, and record your observations in

“Conclusions #3.”
