When Antony Van Leeuwenhoek invented a hand held microscope, that could magnify images up to 270 times, it opened up a lot of new ideas for other people, and other bacteria.
So, without further ado, I give you, three ways in which the microscope changed the world.

1. When he made the new and improved microscope, Van Leeuwenhoek helped scientists discover the cure for polio. Polio, or poliomyelitis, is a sickness that in worst cases, can cause paralysis, or even death. Without the discovery of the hand held microscope, people all around the world would suffer from this horrible disease.

2. Another way in which the microscope changed the world, with it, we were able to make microchips. Microchips are very important in our world, because they help make electronic devices work. Electronics such as: Phones, computers, tablets, etc. These are essential things in our lives, because without phones, we would not be able to call loved ones that are far away, find out where people are when we don’t know, and most importantly, call 911 in case of emergency.

3. Last, but certainly not least, without the microscope, we would not have discovered bacteria.
Antony Van Leeuwenhoek was the first person to ever see bacteria. (Wow! If I was him I’d be pretty proud!) Bacteria are very important in the making of cheese, yogurt, vinegar, etc. They also help some animals digest some of the harder to digest things, that are in grass. Bacteria has actually even helped human intestines to produce Vitamin K!


That is all.

Thank you, thank you very much.

These are the three most interesting things I learned from the microscope video:

1. Polio, the properties of light, and microchips would have never been discovered if there was no such thing as a microscope in the world.

2. Levenhook discovered cells, bacteria and other organisms (which he called animalcules) in the rain water and your saliva using a microscope.

3. The electron microscope can magnify objects up to 10,000,000 times, which is extremely far vision into an object!

The steps for using a microscope are:

1. make sure that the nose piece is on the shortest lens
2. clip the slide into place
3. lower the lens to the lowest possible position
4. always look with two eyes (with or without glasses, whichever works best)
5. adjust the light to brightest point
6. turn the coarse knob towards you to focus the sample
7. use fine focus until it looks clear
8. move the stage to centre the sample
9. rotate the nose piece to the bigger lens and fine adjust
10. when you are done, rotate the nose piece to the shortest lens
11. return the stage to the lowest position if possible and remove the sample.

Here are the three most interesting things I learned from the microscope video:

1. With the microscope we found out about microchips. Without microchips there would be no phones, computers, tablets etc. Life would certainly be very different. Today people rely these for communication, business, education, media, banking and more. Some people wouldn’t survive a day without that microchip.

2.Without the microscope we wouldn’t have found out about animalcules and bacteria. They taught us about many viruses and diseases and also help us make medicine and find cures. How to preserve food and many more ways how the discovery of bacteria helped us.

3.Without the microscope we wouldn’t have found out about cells. Cells help make more efficient vaccines, better medicine and more about plants and animals. Cells have D.N.A inside of them which is really important. D.N.A tells everything about us, animals plants or any living thing. It teaches us about evolution, why animal life is able to grow and exist and more about each living thing that can help us in the future.

If it wasn’t for the microscope we wouldn’t have known about many of these things and our life and our world would of been very different.

Here are three ways (from the video) in which the microscope changed the world:

1. the microscope helped us make major medical discoveries, such as the cure for polio

2. the microscope helps us see bacteria which helps us understand stuff that is related to illnesses and life in general\

3. microscopes helped with the invention of microchips. If we didn't have microchips, you would not be reading this post right now because microchips are in computers, phones, tablets, and many (possibly every) other sorts of electronics.

1.Rotate the objectives to the smallest one which is the low power one. This helps to find your specimen easier.

2.Lower the lens as much as you can by using the coarse adjustment knob.

3.Next you place the slide onto the stage and clip it to secure it.

4.Setup the light control by rotating the diaphragm until you have the right amount of light (For example, pond water is better to examine with less light because many of the creatures don't really like light and would try to avoid it).

5.To focus, turn the coarse adjustment knob toward your body. Keep doing this until your image comes to focus. Use the adjustment knob to focus the image as much as you can.

6.Center your sample by moving the stage.

7.If you want to magnify your sample more: rotate it to the second smallest lens which is the medium power one. Refocus slowly and if you can't see just move the slide back and forth. If you lost the sample just rotate back to the smallest lens and try again. Also if you want, try the high power lens and repeat the same steps as for the medium power one.

8.When you are finished, turn the coarse adjustment knob to raise the lens and take out the slide. Then rotate back to the low power lens.

These are the three things that I think the microscope changed the world:
1. When the microscope was made, it could magnify images a lot bigger than normal sizes. The first microscope could make things 9 times bigger than normal. But when Antonie van Leeuwenhoek made the improved version of that, it could magnify up to 270 times, which was a lot more than 9 times, that greatly increased the potential of finding new things that were too small to see for the human eye.

2.The microscope made us be able to see and discover many small living things, such as bacteria, germs and microbes. We wouldn’t been able to cure many diseases or even knew it was caused by viruses if we didn’t have the microscope. With the microscope, we have found the cure for many diseases like polio.

3.We wouldn’t have microchips right now if we didn’t have microscopes to discover them, microchips are found in a lot of our devices nowadays, like MP3 players, phones, computers, internet servers, and most electronic devices (virtually all of them). Without electronic devices, it would be harder to do things, and we wouldn't be able to make phone calls, we wouldn't be able to do many things that we do today.

Steps to use a microscope:
1.Turn the revolving turret so the least power objective lens is in position.

2.Clip the microscope slide with the object that you want to view on it on the microscope.

3.Lower the lens to the lowest position without going too close to the slide.

4.To look more clearly, keep both eyes open while viewing.

5.Adjust the condenser and light intensity to get the greatest amount of light.

6.Adjust the microscope's distance from the slide to focus better.

7.Centre the sample.

8.Once you get a good focus, you can change to the other objective lenses, but you might need to adjust the light though.

9.When you are done, adjust the lens to lowest objective lens.

10. Lower the stage.

These are the steps you can do to prepare a microscope:

1. Rotate the rotating piece with the three lenses to the shortest one.

2. Put the stage clips to the stage of the microscope to lock the lens underneath it.

3. Rotate the bottom adjustment knob as far as it will go without making it touch the slide that locks the lens.
4. Look through the eyepiece, (the two straight things located at the top of the microscope) while opening both of your eyes to get better view from the microscope.

5. Adjust the diaphragm and the light strengthener to the greatest amount of light.

6. Rotate the adjustment knob closer to you towards yourself until you can see the image.

7. Use the fine adjustment knob to get the clearest image you can get.

8. Move the stage to see your image clearly so you can see what is in what you are looking at easy to see.

9. Rotate the rotating nosepiece to increase the power of the microscope, and also use the fine adjustment knob for more focus on the object.

10. When you are finished looking at the object, rotate the coarse adjustment knob to raise object away from the slide.

11. Take away the slide from the stage, and rotate the nosepiece to the lowest one again.

These are are the top 3 ways the microscope changed the world:

1. Without the microscope we would not be able to make microchips which are very important for making many electronic devices. Microchips are used in: Mp3 players, phones, computers, tablets and more! Without these we would not have the technology we have today and some of this technology is important.

2. Another way the microscope changed the world is Levehook discovered bacteria. Without this we would not be able to cure diseases or know how they happen.

3. Lastly we would not have the cure for polio. Polio is a terrible disease that had many children paralyzed and sick.Now that makes me wonder if we would have made a cure today..... anyways making a cure for polio is really great!

Bye the way I'm posting the steps on how to do work a microscope.
Now That is all.

Microscope instructions

I am going to tell you about how to use a microscope in thirteen simple steps:

1)Grab all your materials,you will need:
a)A standard microscope.

2)When transporting a microscope use both hands:
a)With the left hand on the arm.
b)And with the right hand on the base for support.

3)Rotate the revolving nose-piece to the lowest power or the shortest objective lens.

4)Fasten a microscope slide to the stage using the stage clips.

5)Use the course adjustment knob to lower the lens as far as it will go without touching the slide.

6)While looking through the eyepiece you can maintain better viewing by keeping both eyes open.

7)Adjust the light source and diaphragm to give the highest amount of light.

8)Slowly adjust the adjustment knob towards your body,do this until the image comes into focus.

9)Use the fine adjustment knob to focus the image as much as possible.

10)Move the stage to center the image in your field of view.

11)Rotate the revolving nosepiece to increase the objective lens power,Once again,use the course adjustment knob to focus the image better.

12)When finished,use the course adjustment knob to raise the objective lens

13)Remove the slide and revolve the nose-piece to the lowest power objective lens.

And You Are Done!!
