Hey, Don’t Miss that Blind Spot!

Hey everyone. It’s Poppy here, your resident go-to girl for matters on science! Now, I know you might not like going to science class, but I’m going to tell you some cool stuff I learned from a psychologist I met at a college I visited with my mom. They were talking about the brain, and what happens in order for us to see something. The diagrams looked really complicated, but when she broke it down, I learned something really awesome about our vision!

We have something called a blind spot. And, it’s exactly what you’re thinking. It’s an actual spot where we can’t see. How does this happen? Well, let’s start from the beginning. When we look at an object, say a red apple, it sends physical waves to our eyes that move through the different parts of the eye. You know about your pupil, right? Well, that is just one of the many muscular components that make up our eyes, and allow us to see. Apparently, the pupil is actually a hole that is made from a gap in our eye muscles! Our eyes transfer those physical waves from muscle to muscle until they reach the site of transduction, which means they get turned into something called neural impulses. Now, I know it may seem like a lot of big words, which is what I thought, but the psychologist explained it to me in a simple way: the waves go through the eye, get to a site where things change, and then they come out as messages that are sent to our brains. Those messages tell us what we are seeing, and that we can out the image in our memory.

So, where does this whole blind spot come in? That has to do with memory. Our eyes don’t actually cover all the physical space in front of us when looking at a specific point. There is a spot that we can’t see, but we don’t see a hole or black spot there. Instead, our brain fills it in with our memories of familiar objects. For instance, if we only see a portion of something red, round, smooth, and shiny, our brain registers that the object is an apple. It does the same thing here, which is why we can’t see the blind spot. One way to know it’s there, though, is to look an object with one eye closed, and then switch eyes. The object isn’t in the same place, is it? This means that there is a blind spot, and that our brain fills it in for us! See, science isn’t always about words on a textbook- it can tell us cool things that our bodies do that we didn’t even know about!

Weird Science: Some cool facts about our bodies!

Anatomy  of the Human Body

Hey GirlMoguls! It’s Poppy here, and I came across some really cool scientific facts about the human body. I just wanted to share them with you.

Have you ever held your breath just to see how long you can go without breathing? Ever wonder why we can’t go on without breathing for a very long time? Out of all the oxygen that we breathe into our body, our brain uses up more than a quarter of it. Our brain is the most important part of our body, and it requires the most oxygen to function.

Can you locate the smallest bone in your body? Most people don’t realize but the smallest bone is located in the middle of our ears.

When was the last time you ate today? Chances are you have not digested your last meal yet. It takes about 12 hours after eating for a human body to fully digest its food. It goes through many phases in your digestive system before it is fully digested. Chances are you probably digest your breakfast around the time you have your dinner.

How long can you go without blinking? Can you imagine blinking only once or twice a minute? Chances are your eyes will start to burn and you will need to blink. Without consciously knowing, we blink every 5-6 seconds. However, there was a point in our life where each of us only blinked once or twice a minute. Babies/infants only blink once or twice every minute!

Ever wonder when our body stops growing as we get older? There comes a point in all of our lives when we age that our body physically stops growing. While that is true for most of our body parts, there are two parts of our body that continues to grow throughout our entire lifetime. They are our nose and ears! It’s kind of hard to believe, but it’s true. Well, while it may not be noticeable to a human eye, it certainly happens as we continue to get older.

Living a Better Life: The Science of H2O!

Hey girls, it’s GirlMogul Poppy here with a new science installment! So, you know I’m all about figuring how things work and why things happen. That’s the part I actually like about science! Ever wonder why something works the way it does? Or maybe why our bodies function a certain way? Well, then I’m your girl!

My mom always says, “Drink 8 glasses of water a day!” When I keep asking why, she just responds by saying “It’s good for you!” But, I always wanted to know WHY it’s good for you.

It turns out that you do need about 8 glasses of water a day, and that’s because water makes up a huge part of your body. Your skin, organs, and cells are all made up of a huge percentage of water, and you need to keep replenishing that level so you don’t get dehydrated. When you sweat and do daily activities, water evaporated from your skin into the atmosphere. Therefore, you’re constantly losing a steady supply of fluid that your body needs in order to function properly. Water is one of the best liquids you can drink because it is what your body is made, of, it includes no artificial ingredients, it contains no sugar, it has no calories or fat, and it is pure. Besides replenishment, water also has a ton of other benefits. It keeps the oils from clogging your pores on your face, and prevents acne. Also, it allows you to think more clearly because when you get dehydrated, you brain and organs start functioning slower in order to conserve energy.

But, one of the new reasons I’ve discovered to drink water is exercise! Health studies recommend that athletes start drinking water at least 1 hour before exercise and for at least 1 hour afterward, because of the physical strain you are putting on your body. Be careful though! Too much water (it has ot be a lot) can also be detrimental. Just make sure that if you find yourself drinking over 8 glasses a day, include drinks like sports drinks with a little sodium and electrolytes. Too much water can wash these ingredients out of your system and they are good for you too!

And don’t forget to be environmentally friendly. Tap water is often just as good as bottled water and if you use your own re-usable container like the one shown here, you aren’t adding more plastic that takes a long time to break down into the earth.
