HOW DOES A TORNADO FORM?

Hello Science Breakers.

Today the mission is resolving the following question: How does a tornado form?

In order to accomplish the mission, we will give you some clues in which you have to look for the information is asked in each item.

RULES:

1. You must follow the instructions carefully.2. You must work with your classmate. It is a pairwork.3. You can not cheat. Cheating means a fail mission.4. You have to look for the main information in the clues we provide you.

FIRST CLUE: WHAT IS A TORNADO? ( I remember the main information!)

1. Assignment: You have to read the following text and answer the next questions with long answer. Once you have read the text twice you should answer. You can not go back and copy the answer. It will consider as cheating.

Tornadoes are ferocious and dangerous storms. They whirl and spin like a top. Tornadoes have the power to destroy anything that gets in their way. The tornado is like a whirlpool of wind that develops from a thunderstorm. Thunderstorms develop when warm, moist air rises and cools. This creates clouds. Water vapor condenses and releases heat. This release of heat creates the energy in a thunderstorm. Under certain conditions, when the air moving up into the cloud is very strong, a tornado can develop.

The whirling winds are like a spinning column of air that comes down from the thundercloud. The winds can be as strong as 300 miles per hour (483 kilometers per hour). When the tornado reaches the ground, the whirling winds can cause a great deal of damage. The tornado on the ground follows the same path as the thundercloud. The larger tornadoes can travel fast and can last for hours.

QUESTIONS:

1. What is a tornado?

2. Can be the clouds created by tornados?

3. A tornado doesn’t need wind at all. Is it true or false?

4. The component responsible of creating the energy of a thunderstorm is the

wind created. True or false?

5. A tornado can last at most…….

a)Hours b) Days c) Just one hour d) 30 minutes

SECOND CLUE: TORNADOES ON THE SOCCER FIELD’S STORY

Assignment 2: You have to read this story, and later on you will answer the items.

It was a hot, steamy day for an afternoon soccer game. I was 10 years old and forgot to bring my soccer shoes along, so the coach made me play in sandals. My team was ahead by a few goals. From where I stood in the net, bored and sweating, I had a perfect view of thunderclouds on the horizon.

The game was held at the National Sports Center in Blaine, Minnesota. With nearly forty fields, the National Sports Center is the largest collection of soccer fields in the country.

The longer the game went on, the darker the sky got. Thunderstorms can blow in quickly on summer days in southern Minnesota, but even so, we were surprised at how soon the first raindrops fell.

Before we realized what was happening, a tornado was spiraling down from the sky, spinning tight and fast toward the ground. The tornado touched down on the soccer field. A few miles away, another twister was also dropping from the clouds. A third twister would appear shortly in the distance over the town of Blaine.

I remember being scared but also thinking that the three tornadoes were the most amazing things I’d ever seen

• How would you feel if you were in this weather event?

• Would you do anything differently to make sure you stay safe?

THIRD CLUE: SAFETY RULES IN CASE OF TORNADOESAssignment 3: You have to choose between a list of safety rules we provide you. You must classify them according to the importance you give to them. Of course, you must reason the order of the rules according to your opinion.

In a home or building, move to a shelter, such as a basement or to a small interior room or hallway on the lowest floor and get under a sturdy piece of furniture.

Put as many walls as possible between you and the outside. Stay away from windows. If caught outside in a vehicle, do not try to outrun a tornado. Get out of the vehicle and seek

safe shelter. Mobile homes, even if tied down, offer little protection from tornadoes. You should leave a

mobile home and go to the lowest floor of a sturdy nearby building or a storm shelter.

It is a good idea for your family to select a place to meet following any tornado in case you are separated at the time of the incident.

Avoid elevators and stay away from windows.

FOURTH CLUE: WHERE ARE THE TORNADOES DEVELOPED?

Assignment 4: First of all, we are going to show you a world map and you have to think about the frequent places where a tornado occurs. There is a most frequent place in each continent. Also, you have to say why do you think there are most frequent places where the tornadoes are developed.

ANSWERS:

FIFTH CLUE: FACTS ABOUT TORNADOES

Assignment 5: You’ll see some curio facts about tornadoes. You can only choose three facts you like most. You should say why.

A tornado is a rapidly spinning tube of air that touches both the ground and a cloud above.

Tornadoes are sometimes called twisters. Most tornadoes have wind speeds less than 100 miles per hour (161 kilometers per hour). Extreme tornadoes can reach wind speeds of over 300 miles per hour (483 kilometers per hour). Most tornadoes travel a few miles before exhausting themselves. Extreme tornadoes can travel much further, sometimes over 100 miles (161kilometres). The Tri-State Tornado was the deadliest tornado in US history, killing 695 people. The USA averages around 1200 tornadoes every year, more than any other country. The majority of these tornadoes occur in a geographically unique area nicknamed ‘Tornado Alley’. US States most often hit by tornadoes include Texas, Kansas, Oklahoma and Florida. In 1989 the deadliest tornado ever recorded in the world killed around 1300 people in Bangladesh. In the southern hemisphere tornadoes usually rotate in a clockwise direction. In the northern hemisphere tornadoes usually rotate in a counterclockwise direction. Weather radars are used to detect tornadoes and give advanced warning. Basements and other underground areas are the safest places to seek refuge during a tornado. It is also a

good idea to stay away from window.

SIXTH CLUE: Make a Tornado in a Bottle

Assignment 6: Learn how to make a tornado in a bottle with this fun science experiment for kids. You will answer why that happens in the bottle.Follow the instructions and enjoy!

What you'll need:

Water A clear plastic bottle with a cap (that won't leak) Glitter Dish washing liquid

 

Instructions:

1. Fill the plastic bottle with water until it reaches around three quarters full.2. Add a few drops of dish washing liquid.3. Sprinkle in a few pinches of glitter (this will make your tornado easier to see).4. Put the cap on tightly.5. Turn the bottle upside down and hold it by the neck. Quickly spin the bottle in a circular motion for a few

seconds, stop and look inside to see if you can see a mini tornado forming in the water. You might need to try it a few times before you get it working properly

SOLUTION:

What's happening?

Spinning the bottle in a circular motion creates a water vortex that looks

like a mini tornado. The water is rapidly spinning around the center of the

vortex due to centripetal force (an inward force directing an object or

fluid such as water towards the center of its circular path). Vortexes found

in nature include tornadoes, hurricanes and waterspouts (a tornado that

forms over water).
