In class 1 lever the fulcron is in the middle and the load in on one side and the effort force is on the other side.The class 2 the fulcron is on one side and the load is on the middle and effort force is on the other side.The class 3 fulcron the fulcron is on one side and the load is in the middle and effort force is on the other side

A lever is a machanical advantage by changing the direction of the force you use.When you use effort force to push or pull an object in one direction it travels in the over direction.
Ryan
4/12/2018 01:51:02 pm
You should’ve wrote more about the three types of levers

A lever is a very interesting spy tool there are three kinds of levers. All types of levers have a fulcrum. A first class lever the fulcrum is in the middle. The load is one one side and you push down and the load goes up.
James
4/10/2018 01:52:58 pm
Lever can help lift heavy objects like cinder bricks and let people use less energy
Mr. E.

Did you know that levers make heavy items use less force to lift? Yup,levers are very useful because they help is lift load. But levers aren't only used for work, they can also be used for fun, like a see-saw or catapults! There are 3 types of levers: First Class, Second Class, and Third Class.
Veer
4/12/2018 01:43:52 pm
You should do like one more sent me and explane what the different lever classes do and there good parts and bad parts But you did a perrty good Job but you can do more
Mischa
4/12/2018 01:45:45 pm
You did good but you did not exclaim why each class did.

Great job on your paragraph,but I think you should describe what the three different types of levers are
Zephan
4/12/2018 02:19:32 pm
Good job Zay! Maybe next time you should give a conclusion and talk about the fulcrum, load, and how each class of levers is meant for different uses. Other than these small mistakes, you did great.
Arasin
4/10/2018 01:55:57 pm
Have you ever heard about leavers, there a device that help people lift objects that are to heavy to carry by hand. I think levers reduce the weight, when you push/pull on one side with out stuff on it, it will feel lighter the if u pick it up with your hands, if you use effort force to push/pull in one direction, the load travels in the other direction.

A second class lever is when the fulcrum is one side, and the load is in the middle you push up on the side opposite to the fulcrum and the load will go up
Mischa
4/10/2018 01:56:46 pm
This is what I know about levers. I think levers can disguise themselves in many different ways. There are three different types of levers;first class, second class, and third class levers. First class levers, such as a seesaw, have the fullcrum between the effort and the load. Second class levers, such as a bottle opener, have the load between the effort and the fullcrum. Third class levers, such as a fishing rod, have the effort between the load and the fullcrum. For my conclusion, I think there are three types of levers.

Levers are a simple machine that can help lift things. Levers have a fulcrum, a fulcrum is an object that is most commonly used in the middle of the lever. There are three types of levers, one like a seesaw , another like a bottle opener. The last one has a similar setup to a fishing rod.In conclusion levers are a simple machine that has three different types.
Tasha

This is what I know about levers. I know that a lever needs effort,load, and a fulcrum. Levers help lift things that might be to heavy to lift. Levers makes things easier to lift, so if you we're to lift a dictionary without a lever it would be harder then with a lever.There can be 3 types of levers and that is what I know about levers.
Jai

Sarah
4/10/2018 02:00:22 pm
Up down. Up down. Have you ever played on a see-saw? A see-saw is a class 1 leaver. The spring is called a fulcrum. Leavers are used every day. For example, see-saws, wheelbarrows, and fishing rods are all leavers. A leaver is made with a bar-like item resting on a fulcrum. On a see-saw, the fulcrum is always in the middle. To conclude, a leaver is composed of a bar with a fulcrum that the bar rests on.

4/10/2018 02:03:23 pm
This is my paragraph on Levers. I think that Levers are a tool that lifts load by pushing down on the opposite side. A Lever can help you lift some thing heavey. If you where to lift something it would take more effort but if you where to use a Lever you could push down and your load would come up. Second class levers carry things on its left side and third class levers carry things on the right. In conclusion I think that in sometimes levers can be helpful.

There are six types of simple machines this phargrah is on levers. There are 3 types of levers if the valcrum is in the middle then you need same amount of force. Levers help use pick things up a frat class lever gives you the power of by letting you change the force easy. A second class lever give you power to make less efferent to push an heavy object. Fanily a threed class lever give you power to increase your speed. SPY VEER OUT

There are many simple machines. A lever is one of these objects. The way a lever works is the load is on one end and the effort on the other. There are three different types of levers,first class second class and third class. Levers are made for lifting heavy loads and for work,but they can also be used for fun, like when you are riding a tetter totter!

Levers. They are simple machines that can appear in three different forms. Levers are everywhere, they are masters of disguise that appear in our everyday lives. They can be teeter-totters, they can be used to move heavy loads easier, etc. A lever consists of a fulcrum,
Veer

That phargrah was long and great But you should have told use what the 3 classes do But you did a great job but you are using penny words
Kenzie
4/10/2018 02:09:10 pm
There are six different simple machines,and one is the lever.The lever is a bar that rests on a fulcrum.The lever was made to lift load easier.In total there are three things you need to make a lever,this is what they are, they are a bar,a fulcrum,and effort force to lift the load.Also there are three different types of levers,however each class involves a fulcrum,a bar,and of course effort force.You might be wondering how there is three different types of levers,because when you think of a lever you autimadically think of the first-class so I will describe them.The first-class lever has a fulcrum in the middle,the load on the far right,and the effort force on the far left.The second-class lever has the fulcrum on the left,the load in the middle,and the effort force on the right.The third-class has the fulcrum on the far right,the load on the far left,and the effort force in the middle.In conclusion simple machines are very useful,and can hardly be noticed.So keep an eye out for other simple machines because they are masters of disguise.
Caila
4/12/2018 02:05:48 pm
I love your paragraph it explains everything clearly, you should work on a better explanation for the conclusion though good job There are six simple machines in all. We will be looking a the lever. Levers are things that have a fulcrum at the left side, the right side, or the middle. There are three types of levers. First, second, and third Class levers. The first class lever has the fulcrum in the middle, the load on the right, and the effort on the left hand side, going down. A first class levergives you a mechanical advantage by changing the direction of the force you use. A second class lever has a fulcrum at the right side, the load in the middle, and the effort on the left going up. A second class lever gives you a mechanical advantage by allowing you to use less effort force to lift an object. A third class lever has the fulcrum on the left side, the load on the right side, and the effort on the middle going up. A third class lever gives you a mechanical advantage by increasing the speed and distance you are able to move the load. In concluson, I learned a lot about levers in this lesson.

Michael?
4/10/2018 02:12:50 pm
Levers are one of the simpler simple machines. There are class one, two, and three. The first class is the most common, where the fulcrum is in the middle, and the load is close to the edge. And the effort would be on the opposite side of the load. Next, is the second class lever. When the fulcrum is on one side, so the whole lever is diagonal. And the load would be on the centre of the lever, then the effort would be on the opposite side of the levers fulcrum. The last type of lever is the third class. So the fulcrum would be on a side, just like the second class, and the load would on the other side. And the effort would be in the middle, but a tiny bit closer to the load, so the effort goes to the load and not the fulcrum. The fulcrum is the balance point of a lever that makes the load go down if it is heavier than the strength of the effort. The load is the weight of an object that is on the lever. A load could be anything that has mass and volume. The effort is a force that pushes, pulls, or lifts.
Caila

This is what I know about levers.Levers can pull objects up and down. Think of a seesaw,it can pull the person up and down. The people use force on the lever to make it go up and down. Levers can be used for many different things. A lever has a fulcrum a load and an effort force. Your weight is the effort force. Your friend is the resistance force. If the oppisite person weighs 50 pounds,then you need to push down with 50 pounds. In conclusion that is what I think a lever is
čärtër the great

Joshua

We see levers in our everyday lives. A great example of a lever is a teeter totter. Teeter totters have a fulcrum in the middle, a load on one end, and the effert on the other. Teeter totters are great if your the same weight as the person on the other end, but if you aren’t the fulcrum would have to be closer to the person that is heavier. There are two other types of levers. A type two lever where the fulcrum is on one end, the load on the other, and the effort in the middle. A type three lever is where the fulcrum is also on the end, but the load is in the middle, and the effort is on the end. In conclusion, levers are in our everyday life, but in three diffrent forms.

There are 6 types of simple machines, and the one I'm typing about is the lever. There are 3 different types of levers first-class lever, second-class lever and third-class lever. Levers are made of a bar and fulcrum, first-class levers have the fulcrum is the middle of the bar. The second-class lever has the fulcrum near the end of the bar, and the third-class lever has the fulcrum at the end of the bar. An example of a first-class lever is a seesaw, an example of a second-class lever is a bottle opener and an example of a third-class lever is a fishing rod. If you were on a seesaw you are the effort force on one side and on the other side your friend would be the resistance. In conclusion there are three types of levers and levers help push a load up.

I like it how she added all three levers and examples like a seasaw and bottle opener

Awesome work I like how you added examples , but I’m not sure about the push and load, part.

Levers! Did you know there are three types of levers!? The first class lever has a fulcrum in the middle which is what a lever pivots on. Then the load goes on one end and then the effort goes on the opposite end. The second class lever has the fulcrum on one end and the load on the opposite end finally you apply the effort in the middle. Lastly the third class lever has the fulcrum in the same spot as the second class lever but the load is in the middle and the effort is on the opposite end as the fulcrum!

Good explanation so far but check for spelling and punctuation, you should also add a conclusion.

The lever is one of six simple machines you can use, It can make it easier to move a load, there are 3 classes or levers. Each class does different types of work, Levers require a fulcrum, force and load, They make lifting objects much easier,

I like what you wrote but it would be great if you wrote a bit about the fulcrum and the load and the force

That was great Nicholas. Just one little tweak, I think that you should have gave us an example on levers, but that was great

Good effort Nick! Next time you should say a little bit more about the load, fulcrum and about where you need to apply force on each type of lever.
