Human Eye How The Eye Works For Kids

Your eyes are like two tiny movie cameras inside your head.
They are sending a steady stream of pictures back to your brain, like a television camera sending live pictures back to a TV screen.

Your eyes have a part called the lens, just like a camera. The lens helps to bring everything you look at into focus, so that details are as clear as possible.

What are Rods and Cones?

Human beings are luckier than many other animals because they see in color. Some other animals, such as birds and butterflies, can also see colors.
To see colors, we have special cells in the eye called cones.
They share the work of seeing with other cells called rods.
Rods do not detect the difference between colors and don’t need as much light as cones to make them work.
So at times, rods are more useful to you than cones, such as at night when the light is very dim.
Have you ever been for a walk in the moonlight and noticed how pale, silvery, and colorless everything seems?
Photographers can take pictures by moonlight which are just as colorful as pictures taken by day. So the colors are still there by moonlight, but we can’t see them.
Can you think why this is?
The cones help us to see color, but moonlight doesn’t provide them with enough light to function well at night.

What Is Stereoscopic Vision?

When we use both our eyes, we have a kind of sight called stereoscopic vision.

Because both eyes are at the front, they both see the same object. But your eyes are a little apart from each other, so each has a slightly different view of things.

You can check this if you place two objects, such as drinking glasses, on a table in front of you.

Place one about 8 inches (20 centimeters) away from you, the other 2 feet (60 centimeters) away.

Put your chin on the table with the two glasses in a straight line away from you.

Close one eye, then the other.

Do you see exactly the same thing with both eyes?

Your brain makes use of the fact that your eyes tell different stories.

By comparing the messages from each eye, your brain works out how far away an object is.

Your brain does this in a split second every time you look at anything.

Stereoscopic Vision Test for kids

Why are our eyes on the front of our head, both looking the same way?

It seems a waste of an eye, doesn’t it?

To discover the answer, play this game of throwing and catching a ball with a friend.

You will need:

stiff, black paper or cloth
scissors
a sharp pencil
a ball
thin elastic or ribbon

1.Cut out an eyepatch from the paper or cloth. Using the pencil point, make a small hole on either side of the patch. Thread the elastic or ribbon through the patch.

2. Play at catching the ball with both eyes first. Throw the ball 20 times, and make a record of how often you drop the ball.

3. Now cover one eye with your patch. Keep a record for another 20 catches. Did you do as well? Explain what happened.

Poor Effect AC Air Conditioner For Skin

Unconsciously, you may have spent some time in the air-conditioned room or air conditioner (AC). At the office, car, transportation age, shopping, to the bedroom. You might just find comfort in the midst of a tropical climate that makes hot, unknowingly bad effects on beauty.

Exposure to cold air space can trigger long-term damage to the skin and hair beauty. This happens because the engine air chamber absorbs humidity in the space.

"AC also draw moisture away from the skin causing dry skin. If not protected with a moisturizer, the skin can be easily damaged. Ongoing drought will affect the layer of the skin," says beauty and skin specialists, Dr. Rajan TD, as quoted by the Times of India pages.

When the skin is experiencing dryness itching will easily arise. Air-conditioning is also aggravate skin disorders being suffered by a person.

Air space to absorb water from the air inside the room and grab the outer layer of the skin epidermis. If terjaid constantly, losing water and lack of replacement water from the skin tissue can cause skin peeling, dry and cracked.

Water is essential to keep blood flowing. Water is also useful to maintain skin elasticity. When the humidity chamber disappeared, the skin can wither. The skin is also prone to creases and wrinkles finally accelerate. Latent effects, premature aging.

Effects worse befall those who frequently switch from the sweltering outdoor activities into the refrigerated space, unprotected skin. This extreme temperature changes can trigger enough more serious skin damage.

Adverse effect air more perfect when combined with high exposure to pollution, extreme weather changes, poor diet and other unhealthy lifestyle. Therefore, consider the following beauty tips for maintaining the health and beauty of your skin:

1. Because it is difficult deadly air conditioning in the office, try not to use it at home. Minimize exposure to air conditioners to your skin.

2. Limit the use of soap to areas where the skin prone to dryness. Dr Kshama Vibhakar, consultant dermatologist suggests, "Use lotion to moisturize the skin, not cream. Spread on the neck, face, hands, elbows, and knees. Lotion-based water will add moisture to the skin."

3. You can use the cream after applying the lotion as oils to help maintain skin moisture.

4. Drink plenty of water to keep skin hydrated, even in refrigerated rooms. Do not wait until you feel thirsty. Water is easily absorbed by the body, for it must never forget to drink to keep skin moist.

5. Place a bowl of water when in a refrigerated room. Because air conditioners pull moisture from the room, put water in the bowl is a simple way to reduce the drying effect on the skin when it is refrigerated room.

A Must Have For Homeschool Moms

K5 Learning

Disclaimer:

I am not a homeschool mom. My girls attend a school during the day. That does not matter to me. Just because they go to school, we do most of the education in the evenings and weekends. We learn through play. My girls are always learning but they do not even know it. We have so much fun. As much fun as we have together there are certain subjects that from time to time need to be reviewed such as reading and writing. When the opportunity arrived for me to review K5 Learning I was thrilled.

About:

The K5 Learning program is a program that makes learning math and reading fun. The math includes math examples as well as math facts while the reading focuses on reading and spelling. This program has everyone from kindergarden until fifth grade.

This is the best part, there are two logins one for parents and one for students. To show you how amazing K5 Learning really is, I will tell you all about each one.

Parents:

Before you start this program, it is up to the parent to create an account. The parents account is amazing. Very interactive and a pleasure to work with. There are many resources for the parent as well as for the student. You get it all.

Student and Reports:

In this section, the parent can keep track of the child from a distance. As my girl is just starting first grade, I am focusing more on accuracy rather then speed. Later on however, when speed becomes more important in math, I can always go back and re-assign a lesson or two to help build this up. I can really taylor the program for my girl based on her needs at the time.

Assesments/Change Levels:

K5 Learning recognizes the fact that the parent knows best when it comes tho their children. If at any moment, I want to make a level easier or more difficult, I have the power to do so to suit the needs of my child.

Worksheet Center:

Some parents do not always want their children to be on the computer and so K5 Learning has a huge amount of printable worksheets. They really have everything including a cursive writing section and flash cards. Very well thought out.

For the parent both in school or at home, this program has everything to track and help keep your little one up to par. You have access to everything. All you have to do is choose one or more areas to work with your child on, have them take the assessment and get to work. I only touched upon what the parent has. As this program is really for the child, lets get going and see how much fun learning through K5 Learning really can be.

Children:

Home Page:

This is geared for kids and so the homepage is simple yet very interactive. With three illustrations the child can select from read and math, math facts or spelling.

Reading &Math:

As my little one is in first grade, I like to start with something simple so she can learn the program before she advances. Saves on frustration later on. The reading is really simple and fun. It has some great illustrations and takes the child step by step from letter recognition to sounds. Very simple to follow and fun.

Math on the other hand starts with cute illustrations teaching the kids about number. After that it advances to addition drills. We skipped the number recognition and went to a drill. The drills are great. They start off with a lesson. It explained that anything plus zero is the number. As I previously mention I am more into accuracy then speed. This program is unlike others I have tired in that has patience. It will wait for you and give you a check plus for speed. My girl so far has seen more positive then negative and this makes her want to learn more.

Math Facts:

This is great in that you can choose what to learn. These are more drills and less illustrations but easy for the child to follow with a great lesson the beginning. Like I previously mentions we are starting with zero and advancing based on how my girl feels. I want her to learn at a happy fun pace.

Spelling:

A super important part of eduction, I feel children need to practice this most and my girls are no exception. After choosing the number of words per quiz, my girl had to listen to a word and then spell it out. We are only on 3 letter words but the more she learns with me and in school, I will increase the levels using my parent account.

My only real issue with K5 Learning is that is ages out after fifth grade. With so much to offer, I would love to see them extend the grade levels or come up with a program through high school. They teach the basics in such a fun way.

Bottom Line:

Although my girls attend a school during the day, if I were to home school them, this is the program I would use. It is fun interactive and my girls can learn at their own rate. I love this program and plan on using it for my first grader until she ages out after fifth grade.

Are any of your kids signed up with K5 Learning or any other similar program?

Index 375

I have been teaching biostatistics for more than a dozen years and I am always looking for a book that is readable, thoughtful and not too technical for a math phobic audience. This book does very well on all three criteria and will now be on my short list with Biostatistics: The Bare Essentials, 3e and Intuitive Biostatistics: A Nonmathematical Guide to Statistical Thinking. The prose is clear and the for dummies margin icons for important/dangerous/etc topics really helps to make this an easy and fast read. The book is not too shallow in the topics that are covered. I was not pleased when I saw Bayesian statistics were missing from the index but those ideas are mentioned as web bonus material. There is a bit of mathematical notation early on but readers who truly hate it will be able to read around it without loosing the gist.

The one real shortcoming of the book is the lack of a cohesive introduction to any statistical package. All the major packages (SAS, R, SPSS, etc) are introduced and many of the less expensive options (including web resources) are mentioned. The coverage of the packages are balanced (but the comments on SAS are not entirely true). The book would be much stronger with a web compendium that explains how to do all the common analyses in the common packages.

The book does an excellent job of encouraging people to think about data, as opposed to just doing math.

BIOSTATISTICS FOR DUMMIES is a 390 page book on biostatistics where the emphasis is on clinical trials. From my own experience as a medical writer, I know that Clinical Study Protocols, Clinical Study Reports, Investigators Brochures, and so on, make frequent use of statistical concepts and formulas such as, alpha value, type I error, type II error, Kaplan-Meier plots, Z statistic, t statistic, P value, confidence interval, standard deviation, and others. Most of these formulas are described in this book. This book takes care to explain concepts that might be overlooked in other statistics textbooks, such as the fact that the determination of a P value, "is arbitrary, it depends on how much of a risk youre willing to take of being fooled by random fluctuations, that is, of making a Type I error. Over the years, the value of 0.05 has become accepted as a reasonable criterion for declaring significance" (page 43). This type of description provides a good background for the medical writer. For example, this morning I was reading a Clinical Study Protocol, which had been submitted with a SPA, where the P value for interim analysis was 0.002 and where the P value for analysis when the clinical trial was completed was 0.04. The book fails to provide guidance on how to solve any formulas in biostatistics. The book fails to include any problem sets, and it certainly does not include any answers. This book will not enable any novice to understand any statistical formulas. On the other hand, if you already understand biostatistics and know how to work the formulas by hand, then this book will be useful for tying all of the formulas together, and for providing a "big picture" of biostatistics. The book takes the same tactic as that taken by actor Robert Preston in THE MUSIC MAN.
