joshua mount Rainier

Dear President there is going to be a volcano in North Carolina. It is going to have lave run down slowly.We named the volcano mount Rainier

Illianna Volcanic Eruption

Mt. Rainier Facts:
Dormant. 14,411 ft high
Protected within Mount Rainier National Park
Puyallup is the closest town to the volcano. (20-27 mi away)

Mt. Vesuvius Facts:
Active
Southern Italy near Naples.
17,000 yrs old.

How to protect people of a Volcanic Eruption:

•Listen to a battery-powered radio or television for the latest emergency information.
•If you have a respiratory ailment, avoid contact with any amount of ash.
•Wear long-sleeved shirts and long pants.
•Use goggles and wear eyeglasses instead of contact lenses.
•Use a dust mask or hold a damp cloth over your face to help with breathing.
•Stay away from areas downwind from the volcano to avoid volcanic ash.
Stay indoors until the ash has settled unless there is a danger of the roof collapsing.
•Close doors, windows, and all ventilation in the house (chimney vents, furnaces, air conditioners, fans, and other vents.
•Clear heavy ash from flat or low-pitched roofs and rain gutters.
•Avoid running car or truck engines. Driving can stir up volcanic ash that can clog engines, damage moving parts, and stall vehicles.
•Avoid driving in heavy ash fall unless absolutely required. If you have to drive, keep speed down to 35 MPH or slower.

Mt.Rainier a national park and if that erupts a bunch of people will die. It's by a city!!

Jose Mount Pinatubo

Dear Mr.President,
We believe that the area of Mount Pinatubo might be in danger of a big eruption. Mount Pinatubo is located at the island of Luzon in the Philippines a mere 90 kilometers (55 miles) northwest of the capital city Manila. We believe if we don't do anything about it 800 people may die and 100,000 people could become homeless. The eruption could start on June 15, 2020 by series of earthquakes.


Mount Pinatubo is part of a chain of composite volcanoes along the Luzon arc on the west coast of the island. The volcano experienced major eruptions approximately 500, 3000, and 5500 years ago. We believe that the events that could cause the earthquake will begin on July 2019. A magnitude 7.8 earthquake can occurred 100 kilometers (62 miles) northeast of the Pinatubo region.

Volcano! Grades 6/7

The year is 2020, and a large Indonesian volcano has erupted. It is the worst eruption in recorded history. To make matters worse, Mt. Pinatubo, Mt. Rainier, and Mt. Vesuvius are erupting, all violently.

You are a volcanologist assigned as an aide to the president of the United States. Your assignment is to give the president a report on what can be expected to happen and what steps can be taken to help people cope with the disaster.

Use the Internet or other research materials to locate the volcanoes mentioned and learn some background material about each one. Answer questions such as “What kind of volcanic eruption are we dealing with in each case?” and “How fast is the lava or ash flowing?”

Make a logbook of your findings and recommendations. Who is in danger? What are your recommendations to save people and towns? How will each eruption affect the environment? How long will the effects last?

Post your report for the president on this blog.

Choose a sport and answer the following questions about that sport. Copy and paste the questions with your answers into a new post (don't forget your name). Use reliable websites to help answer the questions.


1. What sport did you choose? What is the history of your sport? When and by whom was it invented? How much has it changed since it was invented? I chose the sport of football. This sport has been around since around the time of 1840. It was invented by many men but perhaps the most important of all is Walter Camp. It has changed a bit because before in by the time of 1840 men only played football for fun and in college instead of in stadiums in front of hundreds or even thousands of screaming fans.



2. Describe the objects in motion in your sport. Do people move around a lot? Do they move in straight lines or do they change directions? Is a ball or other object the main part of the game or sport? In football the teams have to move around a lot they move in many different directions the ball is the main part and the objective is to get it and take it to the goal line.



3. What two things must be measured to determine the average speed of an object? Design a way to measure the average speed of a moving person or object in this sport, such as the speed of a served tennis ball or the speed of a figure skater gliding across the ice. Describe how this speed is controlled by the athlete. The distance and time it takes to get there. There can be an end point and you can use a stopwatch to see how long it takes the person to get there. Stay at the same rate and way that you are running.



4. Review the definition of work (the scientific definition). Try to identify and describe at least two examples of an action in which work is done in your sport. Remember, the force and the distance moved must be in the same direction. What information would you need to calculate the amount of work done? I don't know the scientific definition for work and I could not find it on the internet.



5. Find at least one example of each of Newton's laws of motion in your sport. Describe each example as clearly as possible. the law of motion that is in football is mass a ball can't get from one player to another player without one of the two players throwing it.

1. What sport did you choose? What is the history of your sport? When and by whom was it invented? How much has it changed since it was invented? I chose American football. It was Invented in the United Kingdom and was once rudgy football, mid 19th century but was changed by Walter Camp "Father of American Football. When it was played back then, it was all about running over lines and kicked at a goal.

2. Describe the objects in motion in your sport. Do people move around a lot? Do they move in straight lines or do they change directions? Is a ball or other object the main part of the game or sport? The football is the main object in the game. Its a like two cones connected by the the back, letting it fly really tight in the air. There are two teams that are facing each other. Usually there is only one team that is running, while the other one is trying to stop it; sometimes there will be an intersection and the apposing team will steal the ball. It is all about running and tackling.

1.The sport I'm choosing is Volleyball. Volleybal was invented on Feb. 9, 1895 by William G. Morgan. The game is suppose to be a combonation of handball & tennis. Volleyball has made one changed over the years. The one way it changed was that the sport use to be call Minoette.
2. In volleyball you have to move around to hit the volleyball so that the Volleyball doesn't touch the ground. You can only hit the Volleyball one time everytime it goes to your side of the net.
3. When you measure the speed, you use the formula S=D/T. Speed equals distance divided by time. You would use it to see how fast the athlete runs and how hard they hit the Volleyball.

Golf-
1. Different coumtries had there way of golf. Some countries are Rome, Europe and Germany. We don't know who invented golf. Golf hasn't really changed, you use a club and a golf ball.
2. Your club is in motion when you play golf. And the ball once you hit it. You do alot of walking. You change directions it depends on where you hit your ball, when you go to hit it again. The ball and the club is the main part of the game you need the club to hit the ball.
3. To measure the speed you do divide distance by time. Speed=Distance/Time. The speed is controlled by the athlete is how hard they hit the ball.
4. I don't know the scientific definition of golf. You move to hit the ball and and you walk to where your ball is every time you hit it. The information you would need to calculate the amount of work is how far you hit the ball.
5. First law- when you hit the ball it keeps going till it hits the ground. Then it stops moving.
Second law-
Tird law- when you hit the ball it doesn't come back to you.
