January Selected from: One Minute Mysteries: 65 Short Mysteries You Solve With Math! Setting the Date One night, Elijah and Kevin were watching the debate for the upcoming presidential election. They were in Kevin’s family room taking notes about the topics that were being discussed and the main points each candidate was making. There was going to be a quiz on the debate in their social studies class the next morning. Kevin’s younger brother, John, was sitting at the computer in the corner, working on the invitations for his birthday party, which was going to be on January 6th. He always had his party on the actual day of his birthday, even if it was a school day. He was getting excited about it already, even though it was more than two months away. Kevin had helped him get started on the computer program, but had to move over to the TV when the debate came on. John read aloud what he had written so far: “You are invited to a party for John’s birthday on . . . something, January 6th. Kevin, what day of the week is my birthday going to be? We don’t have a calendar for next year yet.” “How should I know?” Kevin said. “I’m trying to watch this debate.” “Do you remember what day of the week your birthday was on earlier this year?” Elijah asked John. “Sunday,” John replied. “I remember we watched a pro football game on TV during the party.” “Well, then shouldn’t it be obvious which day of the week your next birthday will be?” Elijah asked. REVEAL ANSWER

If you’re anything like me, you probably don’t spend much time thinking about just how incredible our sense of sight really is. Most of us are born with it, and because vision is such a natural part of daily life, we often take it for granted—until one day it isn’t. Maybe you notice your child squinting at a blurry screen or struggling to read a book, and suddenly you realize just how important good vision really is. October 9th marks World Sight Day —a day dedicated to raising awareness about preventable and treatable eye conditions, especially in children. Worldwide, 1.1 billion people live with untreated vision problems that affect everything from learning to playing to growing up confidently. International Agency for the Prevention of Blindness ( IAPB ) established World Sight Day to remind people everywhere to care for their eyes and to advocate for accessible, affordable eye care for all. This year, we at Science Naturally released a beautifully illustrated picture book called How Do You See the World?  —a fun and engaging way to introduce children to the amazing science of eyes and vision. Vision isn’t the same for everyone. Some kids might see clearly, while others might experience blurry or partial vision. Understanding this helps us better support their unique way of seeing and learning. So today, we invite you, parents and caregivers, to take a moment to #LoveYourEyes by focusing on your child’s eye health. Read along with your kids to discover how vision works and learn simple ways to keep their eyes healthy, so they can see the world clearly and confidently. How Does Vision Work? Ever wonder what’s actually happening behind the scenes when you open your eyes—but don’t want to get bogged down in medical jargon? Fortunately, the basics of how vision works are surprisingly straightforward. It all begins with light! Light enters your eye through the pupil , and the iris controls how much light to let in. The cornea and lens work together to bend, or refract, the light so it lands properly on the retina at the back of your eye. The retina contains two types of cells— rods and cones —that absorb light and convert it into electrical signals. These signals are then sent through the optic nerve to your brain, where the occipital lobe processes them into the images you see. Text and Illustrations from How Do you See the World? This seamless chain of events happens in milliseconds, allowing you to recognize faces, read books, enjoy art, and navigate the world. Understanding Vision Impairment When the eye’s internal processes are disrupted, even slightly, it can lead to common vision impairments. Myopia (nearsightedness) occurs when light focuses in front of the retina, making distant objects blurry. Hyperopia (farsightedness) is the opposite—light focuses behind the retina, causing nearby objects to appear out of focus. Fortunately, both conditions are easily managed with corrective lenses, which adjust how light enters the eye so it lands properly on the retina. Text and Illustrations from How Do you See the World? Here’s a quick way to give your child a vision check: Have your little one hold a book or tablet and slowly move it closer and farther away. If they complain of blurriness or eye strain, it might be time for a professional eye exam. Remember, this quick test is no replacement for a proper check-up, but it can help you notice early signs that your child might need help! Living with Low Vision and Blindness Vision impairment exists on a wide spectrum. Some people live with partial sight—often called low vision —where they may see only light, shadows, or indistinct shapes. Others experience tunnel vision or have blind spots in their field of view. Blindness can range from minimal perception of light to no visual input at all. For people with significant vision loss, tools like white canes and guide dogs assist with daily navigation. Assistive technologies, including screen readers, braille displays, and text-to-speech software, help make reading and digital access possible. Human assistance also plays a role—from sighted guides in athletic events like the Paralympics to the everyday support of friends and family. One serious cause of blindness is glaucoma , a condition where increased pressure inside the eye damages the optic nerve. Eye conditions like glaucoma can cause serious vision loss if not caught early. Regular eye exams are the best way to catch problems before they become serious, especially for kids with a family history or other risk factors. Text and Illustrations from How Do you See the World? How to Care for Your Child’s Eyes Understanding vision is only the first step—keeping our eyes healthy is just as important. Here are some tips for how to get started: Schedule regular eye exams.  Kids’ vision can change quickly, so regular check-ups with an optometrist or eye specialist are essential— even if they haven’t complained of problems! Feed their eyes with good nutrition.  Foods rich in vitamins A and C, like carrots, leafy greens, and colorful fruits, help keep eyes healthy. Limit screen time and encourage breaks.  Use the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds to reduce eye strain. Protect eyes from the sun.  Make sure your child wears sunglasses with UV protection when outside. Use safety gear.  Whether playing sports or helping with projects, kids should wear protective eyewear to prevent injury. Build healthy habits early.  Teaching kids to care for their eyes now sets them up for a lifetime of better vision. Whether it’s putting on sunglasses before going outside or taking screen breaks during homework, small daily actions can make a big difference. Helping your child understand the importance of eye health today empowers them to protect their sight for years to come.

Today at Science Naturally , we're celebrating Mole Day! But wait… what is a mole?   Every year on October 23rd , science-savvy individuals celebrate National Mole Day . No, we're not talking about the furry little creatures that dig holes underground. And no, we don’t mean the beauty mark on your skin that’s a bit bigger than a freckle.  So then what exactly are we talking about when we say mole?  The kind of mole we’ll be discussing today is a super important and universal kind of measurement—meaning everyone all over the world uses it. Usually when you measure something—like, say, your foot or hand—you would use centimeters or inches, right? But what if you’re measuring something so tiny that not even a microscope could help you to see it, like atoms? What do you do then? In that case, you use moles !  Still confused? Let’s break it down even further.  You can’t measure out molecules or atoms with a ruler because they’re just too tiny. To give you an idea of just how tiny we’re talking, look down at your fingernail. Pretty small, right? But what if we told you that just one  of your fingernails is made up of trillions of atoms. Measuring them the same way you would measure your foot or a book would be impossible, so scientists came up with a more practical solution! Instead of measuring the size  of molecules, moles help you to figure out how many   there are in an object.  Here’s the mind-blowing part: If you have 1 mole of atoms, that means there are 602 billion trillion of them. The number looks like this: 602,000,000,000,000,000,000,000. That’s an un-mole-ievable amount of atoms!  Let’s apply this to a real-life scenario. If you take a sip of water, you are drinking 1 mole of water—which contains 602,000,000,000,000,000,000,000 water molecules ! Whoa. So why do we call it a mole instead of just using the number 602 billion trillion ?  Do you have a nickname? My name is Sofia, but my family and friends sometimes call me Sof   for short. For the same reason, instead of saying “602,000,000, 000,000,000,000,000”—which takes forever — scientists just say “mole” for short! Similarly, instead of writing out “602 billion trillion,” scientists prefer to write it like this: 6.02x10^ 23 . Don’t worry too much about that formula right now—just know that 602,000,000,000,000, 000,000,000 and 6.02x10 23  is the same thing, even if they look really different.  Why is National Mole Day celebrated on October 23 ?  Well, if you write out the date, it looks like this: 10/23 . And remember that formula we just talked about? The second half of it is 10^ 23 . Pretty cool, right? Here’s the fun part: Mole Day is celebrated from 6:02 am to 6:02 pm , just like the 6.02 at the beginning of the formula!  Who first introduced the concept of the mole as a unit of measurement? Amedeo Avogadro! (No, not like the fruit, avocado. It’s Avogadro .) He was an Italian Chemist from Turin. Because he first proposed the idea behind the mole, scientists named the number after him. That said, it took a whole team of other scientists to double-check and confirm his theory about moles.  Where else can you find moles (besides water)? Everywhere! Moles are in everything, from sugar to sand to the very air you breathe. If it is made of atoms or molecules, you can count it in moles.  That was a lot of information, huh? We hope you enjoyed learning about moles and how they help scientists count itty bitty atoms and molecules. Next time you drink a glass of water or eat a cookie, we know you’ll think about the 602,000,000,000,000,000,000,000 molecules you are taking in with every sip and every bite.  At Science Naturally , we proudly share the American Chemical Society’s (ACS) goal of inspiring young minds to explore the fascinating world of chemistry. Mole Day is the perfect reminder that even the tiniest building blocks of matter—things we can’t even see—play a big role in our everyday lives. Learning about the mole, and scientists like Amedeo Avogadro who helped us understand it, encourages kids to see the world through a scientific lens filled with curiosity and discovery. If your budding scientist is eager to learn more about chemistry or the metric system , be sure to check out some of our engaging titles, including Mole and Tell , Women in Chemistry , and Talking Science . You can also explore more chemistry fun in our blog post from last year linked here .  We hope this post helps your little one head out into the world with a stronger and more confident understanding of science!
