For the assignment on bridges, students were asked to answer the following question after viewing films and sites of on various types of bridges in the world:Which type of bridges would an engineer build for crossing the following: 1. a small river 2. a bigger river 3. a big river with a soft bed and deep water 4. a big and deep canyon 5. a river or land with a distance of 50 football field wide 6. a small water space for a tall ship to go through By Angela (Grade 3) First Draft I am a engineer and I need to cross a small river, so I need to build a beam bridge. Then I must cross a bigger river, so now I have to build a cantilever bridge. And then I have to cross a river that has a soft river bead and is deep, I will need to build a arch bridge. And also I have to cross a canyon that is 50 football field lone and so I have to build a suspension bridge. And last I have to let a very big ship cross with little space, so I need to build a lift bridge or a swing bridge. By Angela (Grade 3) Second Attempt I am an engineer, and I am going to build a bridge so that people can cross a small river, so I will need to build a beam bridge. And then I will build another bridge so more people can cross a bigger river, and now I have to build a cantilever bridge. Then I must build a bridge, for a big river with a soft bed and deep water, I will need t build a arch bridge. And also there is a canyon that is 20 foot ball field long and so I have to build a suspension bridge, and the suspension bridge is made with strings and cable. And last a very big ship has to move forward on the water but it is too tall, so I need to build a swing bridge or the lift bridge. By Jolene (Grade 4 ) First Draft I am an engineer and I will cross a small river with a arch bridge. I am an engineer and I will cross a big river with a beam bridge. I am an engineer and I will cross a river that has a soft bed and deep with a cantilever bridge. I am an engineer and I will cross a river that has a canyon that is 50 football field long with a suspension bridge. I am an engineer and I will cross a river that a very big ship can go through with a lift bridge. I am an engineer a bridge that swings is called a swing bridge. By Jolene (Grade 4) Second Attempt I am an engineer and I will build a beam bridge to cross a river. I am an engineer and I will build a arch bridge to cross a big river. I am an engineer and I will build a cantilever bridge to cross a river that has a soft bed and deep. I am an engineer and I will build a suspension bridge to cross a river that has a canyon that is 50 football field. By Samm (Grade 4) First Draft Hi I’m Samantha a engineer. I’m going to tell you what kind of bridge you would need to go over a different kind of river. Well to cross a small river you would need a beam bridge. To cross a big river you would need a arch bridge. To cross a river with a soft river bed and deep water you would need a cantilever bridge. To cross a canyon that is 50 football fields long you would need a suspension bridge. To let a big ship cross a little place you would need a swing bridge. There are also 6 bridges in all. So what one am I missing. I am an engineer and I build bridges. I will show you why I build a beam, arch suspension, swing bridge. I like making bridges. But when the bridges fall I have to fix all of them all over again. I will have to to home every night. By Samm (Grade 4) Second Attempt Hi, I’m Samantha an engineer. I’m going to tell you what kind of bridge you would need to go over a different kind of river. Well to cross a small river you would need a beam bridge because it is small and will get past a narrow gap. To cross a big river you would multi-span beam bridge because it is a big river and you need a multi-span beam bridge. To cross a river with a soft river bed and deep water, you would need a arch bridge because there is no pier to sink and no rock to sink to the bottom. To cross a canyon that is 50 football fields long you would need a suspension bridge because it has no pier plus it’s a canyon so it’s too low for a pier. To let a big ship cross a little place you would need a lift bridge because it lifts up so it won’t damage the boat. There are also 6 bridges in all. By Tyra (Grade 3) First Draft Arch The keystone that holds all of the stones. They all stay if the key stone holds it tight. So all of the little stones can stay in so they would not fall out. Cantilever That you have to use diving boards only three and then you just have to walk and you are on island. And the bridge that goes up and down that can save the boats from going under the bridge so they can go past. That it has 19 of the bridges that can go very long that you can’t even get past the whole bridge and maybe it will take long to get past the whole bridge. By Tyra (Grade 3) Second Attempt That the bridges are something like a flexible bridge and also a very long bridge that a log can’t eve fit in the space where the water is going. And that you can’t even get pass where the water is going when you want to get passed. The whole bridge and also when you want you can call someone like the worker that builds bridges and tell that you need to build a bridge so you can get passed so you can get home or to your grandma’s because or something like that and also that’s why you have to have a bridge then so you can walk pass or maybe go to your house because you went for a walk. By Shanissa (Grade 4) First Draft A beam bridge is to cross a small river. A cantilever bridge is for a wide river. A suspension bridge is for a soft river bed. A arch bridge is a canyon that is a 50 football fields long. A lift bridge lifts up when there is a very big ship with a little space. y Shanissa (Grade 4) Second Attempt Hi I’m the engineer Shanissa. I’m going to make a swing bridge because there is a soft surface in the ground. It will be a fine bridge. I can build lots of bridges but I think I will build a swing bridge. Bye Bye. By Ashley (Grade 3) First Draft I’m a arch. I am a big bridge. The setting is outside . I was feeling hapy. It happed by the workers building me. I go over the river. A lift bridge crosses a long river. I feel very happy. Cross a river with beds and soft beds is a beam. By Ashley (Grade 3) Second Attempt I am an arch I am large and strong. I am bigger than a beam bridge. Workers built me because I am smart. I am a beam bridge I go over a small river. I am a arch I go over a bigger bridge. I am a arch I have a soft deep water bed. I am a suspension bridge a big deep canyon a river or land with a distance of 50 football field wid. The bridges that I talked about already are the best. The arch bridge is smart and it has metal on the bottom to hold it up. By Ronnie (Grade 3 ) First Draft I would build a suspension bridge. Arch- cross a river that has soft river and deep. Beam- cross a small river. Cantilever-cross a bigger river. Swing bridge- very big ship with little space. By Roman (Grade 4) First Draft If I was an engineer and if I cross a small river, I would use a beam . If I was a engineer and if I cross a bigger river, I would use a bigger beam. If I was an engineer and if I cross a river that has soft river bed and deep I would probably use a suspension bridge. If I were a engineer if I would cross a canyon that is 50 football field long I would use a cantilever bridge. If I was an engineer and I would cross a very big ship with little space I would use a lift bridge. By Roman (Grade 4) Second Attempt If I was an engineer and if I built a bridge over a small river, I would use a beam bridge. Because bigger ones are too big to cross with. If I was an engineer and if I built a bridge over a bigger river, I would use a multi-span bridge. Because a beam bridge isn’t long enough for a bigger river. If I was an engineer and if I built a bridge over a soft river bed and deep, I would use an arch. If I was an engineer and if I built a bridge over a canyon that is 2o foot ball field wide, I would use a suspension bridge. By Lucia (Grade 4) First Draft I am a engineer. I am crossing a small river, I have to cross a swing bridge. I am crossing a river that has soft river bed and deep I have to cross a arch bridge. I have to cross a canyon that is 50 football field long, I have to cross a beam bridge. Last a very big ship with little space, it has to go under a lift bridge. By Lucia (Grade 4) Second Attempt I am an engineer. I have to build an arch bridge to cross a small river. I have to build a cantilever bridge to cross a soft and deep river. I have to build a suspension bridge t cross a canyon that is 20 football field long. Last I have to build a lift bridge so a ship can go to the other side of the bridge. That’s all the bridges I need to build so people and boats can cross. By Tracy (Grade 3 ) First Draft Cross a small river. Beam Cross a big river. Cantilever Cross a river that has soft river bed and deep. Beam A canyon that is 50 football fields long. Cantilever Very big ship with little space. Beam If I were an engineer I would build a cantilever because it takes days. By Tracy (Grade 3 ) Second Attempt I’m a engineer, and I want to build a Beam bridge across a small river that people can walk across. I’m still an engineer and I want to go and walk across a big river I would want to build a cantilever bridge. I still goona be a engineer, so I’m gonna build a canyon that is twenty football fields long so I would us a suspension bridge. For all my life I’ve been an engineer and I want to cross a very big ship with little space so I need to build a swing bridge. By Steven (Grade 4) First Draft If I want to cross a small river, I would use a beam. If I want to cross big river use cantilever bridge. If I want to cross a soft and deep I use swing bridge. If I want to cross 50 football field long I use suspension. If big ship come I use lift bridge I know because I am a physical engineer. By Steven (Grade 4) Second Attempt If I want to cross a small river, I would use a beam bridge. If I want to cross a bigger river I would use a cantilever bridge. If I want to cross a river that has a soft river bed and deep, I would use a swing bridge. If I want to cross a canyon that 50 football field long I use the suspension. If there was a big ship I would use a lift bridge. By Sonya (Grade 4 ) First Draft I am writing about bridges today. There are many kinds of bridges in the world short, long, big, small and short. I will name some bridges Beam, Arch, Cantilever, and suspension. I am a bridge engineer and I am going to talk to you about bridges. The Beam bridge was first made by putting a tree trunk on the other side of the river. If the piece of wood was thin that mean it does not have a stable structure. So if it doesn’t have a stable structure it will snap. Some time the beam bridge will have a pier. The arch is made from brick. The arch is shaped like a wide n because if the water is too deep the bridge will sink so that’s why they made the arch. The arch is like a wide bridge. A cantilever is like a diving board but with two carxter. The cantilever is like the arch. They build the cantilever because they build arch the arch is for deep water. By Sonya (Grade 4 ) Second AttemptBR> I am writing about bridges today. There are many kinds of bridges in the world short, long, small and big. I will name some bridges Beam, Arch, Cantilever, Suspension, lift bridge and swing bridge. I am a bridge engineer and I am going to talk to you about bridges. Beam bridges were first made by putting a tree trunk from one side to another side. If the tree trunk was too thin, it would snap. A beam bridge is good for small rivers. Some time the beam bridge will have a pier. The arch is made from brick. The arch is shaped like a wide n because if the bottom of the water is too soft the arch pier will sink. Did you know the longest bridge is 20 football fields long?. The cantilever is like three diving board put together. It is called the carxter. Did you know the longest suspension bridge is 100,062 feet long? The suspension bridge could be made from string or cable. To make the suspension bridge you need to throw a rope to the other side and hang rope on the bottom and hang wood on the very bottom. The lift bridge is for when you pull on a rope for the boat to go by. It’s like when you go to the airport and then you leave you have to roll your window so you can pay. By Ilyas (Grade 3) First Draft The bridges rivers canyon because it is s50 football field long and your cross a river that have soft river bed and deep very big ship so go under that river because it is so high I have sat in the river with many big ships have small space. By Ilyas (Grade 3) Second Attempt The biggest river is canyon because it is 20 football field long. And you should true drive our walk. It would be more better if you drive. That would be the best thing to do. When I was making canyon someone asked are you the one who made the bridge. I said yes then he said I want to know how to make a bridge. Then I said it is not spoll. I know he said. But I still want to learn. Then I said to the first thing you need is a cantilever when you using the bridge and some of them you know I think then he make he was a fastest person. I saw he and I made 5 canyon bridges and we broke one of the bridge then that was the funnest day. By Navaneet (Grade 4 ) First Draft A beam bridge is when the ground and then you put a tree trunk on it. Then when the ground is wider. Then you have to put a longer tree trunk and skinner then it will break. That is a beam bride. A arch bridge is made with stones. A cantilever bridge is a long bridge. A suspension bridge is like a 50 football field and the meter is 1990. That’s why bridges are good. By Navaneet (Grade 4 ) Second Attempt A beam bridge is when the ground and then you put a tree trunk on it. Then when the ground’s wider. Then you have to put a longer tree trunk and skinner then it will break. Also there is a arch bridge with it is made of stone and the top of the arch bridge there is a stone on top so the horse rides on it. A cantilever bridge is a long bridge when the gap is too big then they had to build a cantilever bridge and it was really big. Also there is a bridge called the suspension bridge is 20 or 30 soccer field and it is 1990 meters. A multi-span bridge is when you put a rope on a tree and then it will be a multi-span bridge. By Anthony (Grade 3 ) First Draft Cross small bridge. Why. This will be nice and easy just change a log put it by the thing. This bridge is a beam bridge. Cross bigger bridge. Get two pieces of log and find a rock after it will take more than one. This bridge is a pier bridge. For this bridge you will need two diving boards and not log diving so then you can cross . Your bridge is cantilever. You need to find out it is a arch bridge. The ship needs to get under so it is a lift bridge. By Anthony (Grade 3) Second Attempt Cross small bridge. Why. This will be nice and easy. Just get a log put it by the bridge. This bridge is a beam bridge. We want to make a new bridge because the space got bigger. You will need 2 logs which you should call a span. Then get a big rock which they call pier. This is a multi-span bridge. Now the bottom got more soft you will need an arch bridge. It is better than the multi-span bridge. Because it has bricks and a key stone. So when you put on the key stone it pushes against the bricks. Let’s say you have tow diving boards you will need to put one on each side. Then put a very small thing over top. The biggest suspension bridge is twenty football fields long. You can also have tow trees and a big hole in the middle. The lift bridge is a bridge that will lift for a boat. So the boat can get under. A swing bridge is not that much different than a lift bridge. It just swings around. By Shawn (Grade 3) First Draft I am a engineer and I am talking about rivers. If you cross a small river you would need a beam bridge because it is strong. If you cross a bigger bride you would need a cantilever bridge because it is curved. A soft and deep river is a suspension bridge because it is long. A big and long beam is 50 football fields because it is very long and wobbly. By Shawn (Grade 3) Second Attempt I am an engineer and I am building bridges. I am building a small river and you would need a beam bridge to cross the river because the river is not that wide. I am building a bigger river and you would need a pier bridge because a multi-span is two beam bridges with a rock in the middle. A big river with a soft bed and deep water is a arch bridge because it has small rocks that are strong. A big and deep canyon is a cable bridge because it’s made out of wood and string. A river or land with a distance of 20 football fields wide is a suspension bridge because it is very long. A very big boat to pass is a lift bridge because it stops all the traffic and lets the boat pass. By Rajneel (Grade 3) First Draft You need a beam bride to cross a small river. You can use a arch bridge because the arch can fit good and the arch has a keystone in the middle. To cross a soft river bed and if it is deep you need a cantilever and use diving boards to do it. A canyon that is 50 football fields long is the suspension bridge. A ship with little space is a lift bridge. By Rajneel (Grade 3) Second Attempt I am an engineer. Build beam bridge to cross a small river. You need a cantilever to pass a bigger river the bridge was chosen by me because a cantilever is a way to pass a bigger river. A big river with a soft bed and it is deep it is a arch bridge. A canyon that is 20 football field long is a cantilever bridge. A ship with little space is a lift bridge because it can give the ship to pass. By Alex (Grade 3) First Draft I am an engineer. Now I’m going to cross a small river , ;put a beam bridge. Then to cross a bigger river, I would use an arch bridge. Now to cross a river that have soft river bed and deep is swing bridge. To cross a canyon that is 50 foot long is suspension bridge. How to have a bridge for a very big ship with little space is lift bridge. By Alex (Grade 3) Second Attempt I am an engineer. I need to build a bridge to cross a small river to do that I need a beam bridge because I can’t jump to the other side. I need another bridge because it is bigger and to do that is to put a multi-span bride because it’s bigger than one log. Now it’s a bigger river Now I can’t put a beam bridge so then I use an arch bridge because it’s made out of little stones and you can make it as long as you want. Now I need a bridge to cross a river that have soft river bed and deep is a cantilever because it was three diving boards. Now I need another bridge to cross a canyon that is 50 foot long is a swing bridge. I need another bridge because I need to have a bridge for a very big ship with little space is draw bridge. By Paigep (Grade 3) First Draft I am an engineer and I build bridges. I will show you why I build a beam, arch, suspension, swing bridge. I like making bridges but when the bridges fall I have to fix all of them all over again I will have to go home every night. By Paigep (Grade 3) Second Attempt I am an engineer. I build big and small bridges. I build arch beam multi-span cantilever bridge, suspension lift bridge and swing bridges. But if I am on the other side of the city I will have to come and go back to work in the morning. By Sams (Grade 3) First Draft I am an engineer and I am going to build a bridge. The river is a small one so we will do a beam bridge. The beam bridge has a hard bed not deep water when it is dig out. Not deep water and not soft bed it is time for multi-span bridge with a island in the middle and two thick twigs on the island. The Romans created the arch bridge. The cantilever bridge is like diving bridge. The suspension bride is longer than the cantilever and the arch bridge. The lift bridge lifts when a boat comes through. The swing bridge has a mountain and a string that sounds record. I think that being an engineer is fun to build a bridge. By Kyle (Grade 4) First Draft Hi, I’m engineer Kyle I want to build a bridge. I need one for a small water space so I am going to make a beam bridge. Now I have a bigger gap of water so I need a multi-beam bridge. Now I have to make a bridge for a bigger river with softer sand at the bottom so I need a arch bridge. If I need to walk across a canyon I would need a suspension bridge. And if I need one that is twenty football fields wide, I need a cantilever bridge. Oh great one more bridge to go then I done. If a boat needs to go through a bridge I would need a lift bridge. There that is all of the bridges that I know of but I might know more later. For the assignment on electricity, students were asked to write about electricity right after they saw the electricity presentation by EPCOR.Electricity Travels by R Grade 1Electricity goes through the ground. Electricity is very nice to you because it gives you light.
Electricity can burn you. It will take
out a lot of yur skin. If a power line is on you, it will go right through you because
it wants to go into the ground. Electricity wants to go to a
station called Epcor. The best thing to do around electricity is nothing. Stay away from it that's
whaat to do. If anyuone is around electricity
step ten centimeters far. I am telling everyone to stay away from electricity. So everyone in the
world be careful of fire.
Someone could really get hurt around fire. So be careful around fire.
That's why electricity is nice to you sometimes.
That's why I'm not ever going to go near electricity.Electricity by N. Grade 2 |
For the writing on Magnets, students were asked to write about what they learned about magnets after they finished the unit on Magnets. Below is a sample writing from a grade 2 student.
Magnetism by T. Grade 2
Hi I'm T. I can tell you all about Magnets. Do you want to hear about them. It's easy to explain. But the most amazingest thing is that on a bar magnet, there is an N. and an S on each side of the bar magnet. And the N always points to the north pole and the S always points to the south pole. Magnets do not atttract to everything! They do not attract to pillows, rubber, shirts, pants, all sort of things. And things it does attract to are: iron, steel, dime and others. Magnets are used by doctors, dentists and some other occupations as well. A laow of the magnetism is: All magnets have north and south poles. The poles are the areas of strongest magnets or pulling force. If you rub something that is not magnetized on a magnet that is strong, it will turn into a magnet itself. And it will pick up other magnetic things.And if you bang it against hard material, it will loose it magnetic. Thanks for listening to my magnetic facts.
