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.

I liked the project because
it was fun.Also I liked because it
was gooey.

Jocelynne's egg project(The Blue Chicken)

I really liked this egg drop project our science teacher made us do. The egg thingy was called the blue chicken. Ms. Zimmer climbed a ladder and let everyone's project one by one and most of the eggs cracked we used materials such as: plastic bags, bowls, cups, balloons, cotton balls, and string.So however, we had a lot of fun.....

victorias egg project.

We just did an egg project today at school and i just had allot of fun.We named it blue chicken. What i really loved about it was when we made it. We made it out of string,a cup,balloons plastic bag , cotton balls,and a plastic bowl.It was extremely fun.
I liked the project even though its a work in progress. We had to make a egg dropper, and put the egg in it like a egg with a parachute falling. but was last place Cuz egg went about 0.87 sec before hitting the ground. I liked the project when it fell to the floor really quick but what I didn't like about it is when it was not going slow enough to flow down to the ground.

I enjoyed this project because it was very fun. I liked the different parts of it. All of them except for the writing part. My favorite part of the project was the actuall dropping of the eggs. I saw that there was less air resistance to mine and Jonny's experiment. It went down pretty fast so there was a lot of speed and the reson for this is because the experiment was kind of small.
To improve my experiment so that my egg would fall slower. I would also put more things to improve it. I would also put more balloons on it so that it could slow down more even though it was pretty slow.



genny

What i liked about the egg drop was creating it
and blowing the balloons .What i didnt like about
the egg drop was worring about my egg breaking.

If i could change the project i would add more cotton.
I would also use hot glue for nothing could fall out.

(:ELiZABEtH:)

WAT I LIKED ABOUT THIS PROJECT
WAS CREATING IT;WAT I DIDNT LIKE
ABOUT THIS PROJECT WAS THAT
MY TEAM WON AND THAT OUR EGG DID
NOT CRACK;I SAW THE SPEED WEN THE
PROJECT WAS FALLING,AND HOW I SAW
THE MASS WAS WEN I LOOKD AT HOW FAST
THE EGG DROPED AND THE AIR RESISTENCE
WAS OF HOW SLOW SOME WENT AND THE
SAME THING WITH THE GRAVITY:)

Karina Garcia

To start over i am going to tell you that my egg
project was super cool and exciting and guess what we won .
For me the project was verry fun and interesting to do.All the
work that whe did was verry fun,for me the hard part was wh-
en whe started it because whe didnt know how whe were goi-
ng to design it and how whe were to make it go slow.

My project needed a lot of hard work to accomplish
it.But for me the most important thing is that whe won and whe
had to put lots of bollons and cotton balls so that way the parachute
wont go fasdt down and it wount break the egg.

Egg Drop
What I liked about the experiment was how we got to build a model for our egg. And watch the eggs drop. What I would I would do differently was add another plastic bag and protect the egg from cracking.
When the eggs were being dropped they went down fast, depending on how much weight there was. And what materials were used. We only had one bag and no protection so the egg went down, but not as fast as others because of the light weight.

Egg Drop

I like this experiment because it was fun and we got to use an egg. I didn't like this experiment because people were saying that are egg wouldn't work but it did. What I would do different is protect are egg more, so it wouldn't crack.

When Miss Zimmer dropped are egg it went down slow and fast. She dropped every ones egg at the same height. The egg was heavy, but not a lot of things were attached to are egg. It was string, tape and a bag. Are egg didn't stay in the air.

Anzueth

I like the egg drop becuase it was fun and it was a challenge It was Kind of hard because my group frogot to bring the supplies and we were limited with Mrs. Z's supplies but still our egg didn't break. I Would have made the contraption thingy ma bob weigh a little less so atleast it could be in the air for one second.

We didn't have very good air resistance because the ballons made it weigh more so it went faster than alot of other experiments. Gravity Also weighed it down too.

sam

What i liked about the project was that i got to build it. What i did not like was that the project failed. The thing im gonna do different next time is put less weight in it. Im gonna plan the project days before the day of the project and test it days before.

What also happened was that it was one of the worst projects in the class. The other projects runned smoothly and had no problems.

rebekah

I liked the whole project. We got to design an egg dropper, and then put eggs in them. Some survived and some didn't. When my egg dropper got to the ground the egg rolled out but the egg survived. My egg was the first to survive, but in second place for speed.
I thought this project was easy and hard. It was easy building it, but hard in thinking if the design was going to go the slowest.
Gravity came in by pulling it down to the ground. Air resistance came in from the bags, the air was holding the bag up from falling so fast. My egg droppers speed was 1.12, but another was 1.13. I came in second place.

Julie Lynne Egg Drop

We did an egg drop project in science.
I liked the fact ours came in second. It would have been better if it was first but still.
I wouldn't have changed our design, execpt for maybe putting a balloon on in.
We used a cup, string, plastic bags and cotton balls.

Frances

well what i like about this project was about making it with all the materials and working in groups. It was kind of hard trying to think about how to make it and since we didnt have an egg yet we didnt know if we needed to make it bigger or smaller then we kind of needed to know the weight so our egg drop "Blue Chicken" would go slower and so it would'nt break.

we used a lot of cotton and cups for protection so our egg wouldn't break or crack but when ms.zimmer dropped it go slower it went kind of fast but it didnt break.

Brandon

I liked that the project was fun and entertaining. I also liked building the stuff ourselves. The thing I would do differently is i would add more balloons and cotten balls so the egg woyld stay up longer and have more safety.

johnny

speed was not good for the eggs if it WAS FAST IT WOULD BREAK it WAS fun MAKING THE THINGS all THE materIALS IT was INTERESTIng and it was better cuz were working groups
and their was a lot of air resisstance

and gravity was slamming eggs to earth whatever your writting and um um that . . . . .their was air resistance in the wind was making the egg slam to the ground because of gravity

EGG DROP

What I liked about the egg drop was creating the model & seeing the egg drop & seeing if it dropped fast, slow, if it cracked, or didn't crack. What I didn't like was people kept making comments on everyone else's egg drop model. One thing I would do differently to my model is make the egg more protceted. Although, it wouldn't be slow, I think it would be better if it didn't break & go slow.

The concept was to make sure the egg dropped the slowest. Eggs that were more protected dropped fast, eggs that weren't as protected dropped slower. The eggs with more protection dropped fast than the other models. My group use a small amount of material, so it didn't drop fast.

Lead Movie Roles: Animal & Plant Cells







































Starring Roles

Nucleus:
The nucleus is the most obvious organelle in any eukaryotic cell. It is enclosed in a double membrane and communicates with the surrounding cytosol via numerous nuclear pores. Within the nucleus is the DNA responsible for providing the cell with its unique characteristics. The DNA is similar in every cell of the body, but depending on the specific cell type, some genes may be turned on or off - that's why a liver cell is different from a muscle cell, and a muscle cell is different from a fat cell. When a cell is dividing, the nuclear chromatin (DNA and surrounding protein) condenses into chromosomes that are easily seen by microscopy.

Nucleolus: The prominent structure in the nucleus is the nucleolus. The nucleolus produces ribosomes, which move out of the nucleus and take positions on the rough endoplasmic reticulum where they are critical in protein synthesis.

Cytosol: The cytosol is the "soup" within which all the other cell organelles reside and where most of the cellular metabolism occurs. Though mostly water, the cytosol is full of proteins that control cell metabolism including signal transduction pathways, glycolysis, intracellular receptors, and transcription factors.

Cytoplasm: This is a collective term for the cytosol plus the organelles suspended within the cytosol.

Centrosome: The centrosome, or MICROTUBULE ORGANIZING CENTER (MTOC), is an area in the cell where microtubules are produced. Plant and animal cell centrosomes play similar roles in cell division, and both include collections of microtubules, but the plant cell centrosome is simpler and does not have centrioles.

During animal cell division, the centrioles replicate (make new copies) and the centrosome divides. The result is two centrosomes, each with its own pair of centrioles. The two centrosomes move to opposite ends of the nucleus, and from each centrosome, microtubules grow into a "spindle" which is responsible for separating replicated chromosomes into the two daughter cells.

Centriole (animal cells only): Each centriole is a ring of nine groups of fused microtubules. There are three microtubules in each group. Microtubules (and centrioles) are part of the cytoskeleton. In the complete animal cell centrosome, the two centrioles are arranged such that one is perpendicular to the other.

Golgi: The Golgi apparatus is a membrane-bound structure with a single membrane. It is actually a stack of membrane-bound vesicles that are important in packaging macromolecules for transport elsewhere in the cell. The stack of larger vesicles is surrounded by numerous smaller vesicles containing those packaged macromolecules. The enzymatic or hormonal contents of lysosomes, peroxisomes and secretory vesicles are packaged in membrane-bound vesicles at the periphery of the Golgi apparatus.

Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells. Hydrolytic enzymes of plant cells are more often found in the vacuole.

Peroxisome: Peroxisomes are membrane-bound packets of oxidative enzymes. In plant cells, peroxisomes play a variety of roles including converting fatty acids to sugar and assisting chloroplasts in photorespiration. In animal cells, peroxisomes protect the cell from its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria. The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.

Secretory Vesicle: Cell secretions - e.g. hormones, neurotransmitters - are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for release.

Cell Membrane: Every cell is enclosed in a membrane, a double layer of phospholipids (lipid bilayer). The exposed heads of the bilayer are "hydrophilic" (water loving), meaning that they are compatible with water both within the cytosol and outside of the cell. However, the hidden tails of the phosopholipids are "hydrophobic" (water fearing), so the cell membrane acts as a protective barrier to the uncontrolled flow of water. The membrane is made more complex by the presence of numerous proteins that are crucial to cell activity. These proteins include receptors for odors, tastes and hormones, as well as pores responsible for the controlled entry and exit of ions like sodium (Na+) potassium (K+), calcium (Ca++) and chloride (Cl-).

Mitochondria: Mitochondria provide the energy a cell needs to move, divide, produce secretory products, contract - in short, they are the power centers of the cell. They are about the size of bacteria but may have different shapes depending on the cell type. Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds (cristae) as seen in the cross-section, above. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell.

Vacuole: A vacuole is a membrane-bound sac that plays roles in intracellular digestion and the release of cellular waste products. In animal cells, vacuoles are generally small. Vacuoles tend to be large in plant cells and play several roles: storing nutrients and waste products, helping increase cell size during growth, and even acting much like lysosomes of animal cells. The plant cell vacuole also regulates turgor pressure in the cell. Water collects in cell vacuoles, pressing outward against the cell wall and producing rigidity in the plant. Without sufficient water, turgor pressure drops and the plant wilts.

Cell Wall (plant cells only): Plant cells have a rigid, protective cell wall made up of polysaccharides. In higher plant cells, that polysaccharide is usually cellulose. The cell wall provides and maintains the shape of these cells and serves as a protective barrier. Fluid collects in the plant cell vacuole and pushes out against the cell wall. This turgor pressure is responsible for the crispness of fresh vegetables.

Chloroplast (plant cells only): Chloroplasts are specialized organelles found in all higher plant cells. These organelles contain the plant cell's chlorophyll responsible for the plant's green color. Chloroplasts have a double outer membrane. Within the stroma are other membrane structures - the thylakoids. Thylakoids appear in stacks called "grana" (singular = granum).

Smooth Endoplasmic Reticulum: Throughout the eukaryotic cell, especially those responsible for the production of hormones and other secretory products, is a vast network of membrane-bound vesicles and tubules called the endoplasmic reticulum, or ER for short. The ER is a continuation of the outer nuclear membrane and its varied functions suggest the complexity of the eukaryotic cell.
The smooth endoplasmic reticulum is so named because it appears smooth by electron microscopy. Smooth ER plays different functions depending on the specific cell type including lipid and steroid hormone synthesis, breakdown of lipid-soluble toxins in liver cells, and control of calcium release in muscle cell contraction.

Rough Endoplasmic Reticulum: Rough endoplasmic reticulum appears "pebbled" by electron microscopy due to the presence of numerous ribosomes on its surface. Proteins synthesized on these ribosomes collect in the endoplasmic reticulum for transport throughout the cell.

Ribosomes: Ribosomes are packets of RNA and protein that play a crucial role in both prokaryotic and eukaryotic cells. They are the site of protein synthesis. Each ribosome comprises two parts, a large subunit and a small subunit. Messenger RNA from the cell nucleus is moved systematically along the ribosome where transfer RNA adds individual amino acid molecules to the lengthening protein chain.

Cytoskeleton: As its name implies, the cytoskeleton helps to maintain cell shape. But the primary importance of the cytoskeleton is in cell motility. The internal movement of cell organelles, as well as cell locomotion and muscle fiber contraction could not take place without the cytoskeleton. The cytoskeleton is an organized network of three primary protein filaments:

- microtubules
- actin filaments (microfilaments)
- intermediate fibers
