Can you see sound

Introduction

Do you think you can see sound? Well when you see a baby inside a mothers belly that is not a camera or an x-ray. It is sound that they can detected. Ultra sound is a medical technology that uses high sound frequency sound waves. This creates echos that creates an images in the body. This type of scientific method was used in World War 1.

 
Opinion

I think the reason we can't see sound with our eyes is because we can't detect small sound waves. A machine that is designed to see sound can probably see something from 10 miles away. If anyone could see or hear though walls without a machine the army would be very well made.


I hope you enjoyed my blog. The question of this blog is what would you do if you could see though walls with your hearing. I got all the information from Wonderopilis.

Why is Ice slippery

Introduction

Ice is very slippery when its snowing out side with ice it is dangerous to drive. But for sledding it is a good thing to have as much speed and ice can give that. But what makes ice slippery? Many people think it is the solid of the ice but it is actually the water in side. Scientists have discovered that there is a very thin layer of water that exist at the outer most part of the ice. Even the ice that is freezing.

Challenge 

The challenge for this blog is if you ever thought of why ice was slippery what did you think made it slippery. The information in this blog was found in Wonderopilos.

Time

Introduction 60 seconds per minute, 60 minutes per hour, and 24 hours per day. Time ticks and life doesn't speed up or slow down for you. Your future can be interesting but when all you think about is your future then your not making the most of the present. Also if you don't make the most of the time that you have then time will fly faster than usual. There is also no way to speed up time.
Opinion 

 I wish we had more time sometimes because if you had more time in a day what would you do. It would be so much more productive. I would get more work done, have less stress to deal with. But since we only have 24 hours it isn't enough sometimes.  60 seconds per minute, 60 minutes per hour, and 24 hours per day is not a lot of time if you really think about it. I think of an hour as 10 minutes then 10 ten and so on, since i think like that time goes by so quickly.


 Challenge 

The challenge for this blog is to go in the comments and say what you would do with more time. Or would you want less time and tell me about that. All the information in this blog is from Wonderopolis. Remember if your not living in the present then your probably living in the past.
