Fact of the day

Level	Fact	From
1	Rules help us. They keep us safe.	Kind Rules (Citizenship)
2	Wash your hands with soap and warm water. Rub, rub, rub, and then rinse them clean. Always wash before you eat.	Strong and Well (Health)
3	Try to fill half your plate with fruits and vegetables of many colors. Grains include bread, rice and pasta, and whole grains are best. Protein helps build your muscles. You can get it from beans, eggs, fish, meat or nuts.	The Five Food Groups (Health)
4	Every choice means giving something up. Say you have one free Saturday. You can go to the pool with a friend, or you can go to the fair. If you pick the pool, you miss the fair. The thing you give up when you choose is called the opportunity cost. It is the next thing you would have picked if you had not made your choice.	Scarcity and Choices (Money)
5	Where does the energy in your lunch come from? It all starts with the sun, high up in the sky. Green plants catch sunlight in their leaves, and they use it, along with water and air, to make their own food. Because plants make food, scientists call them producers. Grass, trees, and even the tiny green living things that float in a pond are all producers, and nearly every food web starts with them.	Food Webs (Science)
6	How can you tell morning from night when you say the time? After the time, you add a few more words. In the morning you add de la mañana, in the afternoon and early evening you add de la tarde, and at night you add de la noche. For example, Son las nueve de la noche means it is nine o'clock at night, which is close to bedtime for many families. Now look at a clock in your home or your classroom and think about what time it is. Then try to say the time out loud in Spanish, with the right words for the part of the day.	¿Qué hora es? (Languages)
7	What happens when you play more than one note at the same time? When you sing a tune, you are singing the melody, which is the main line of single notes that you could hum one after another. Harmony is what happens when other notes sound together with the melody and support it. A group of three or more different notes played at the same time is called a chord. Chords are the backbone of most songs you hear, from campfire tunes to enormous orchestra symphonies. They give a melody its color and emotion, a little like the background of a painting gives the main figure its mood.	Chords and Harmony (Music)
8	Much of what we know about inheritance began in a garden in the middle of the 1800s. There, a scientist named Gregor Mendel grew thousands of pea plants and studied their traits very closely. Some of his plants were tall, and some were short. Mendel crossed them, which means that he carefully moved pollen from one plant to the flowers of another. When he crossed a tall plant with a short one, all of the young plants grew tall, and the short trait seemed to vanish completely. But when those tall young plants were crossed with each other, about one in four of the next plants came out short, so the short trait had been hidden, not lost.	Genes and Traits (Science)
9	A fourth fallacy is the slippery slope, which claims that one small step will lead, through a chain of further steps, to some extreme result, without showing that each step really has to follow. For example, someone might warn that if students are allowed to pick one song for the class party, next they will want to pick every lesson, and soon nobody will be in charge of the school. Each link in that chain is a guess. It is not a fact. To spot fallacies, slow down and ask yourself a few careful questions. Is the reply about the idea, or about the person? Is this really what the other side said? Are there truly only two possible choices? Does each step have to follow from the one before it? Asking these questions helps you judge an argument by the strength of its reasons.	Spotting Logical Fallacies (Think)
10	Why do so many bridges look like rows of triangles? Engineers call a frame like that a truss, and it works because a triangle is rigid: if you join three bars at their ends with pins, the shape cannot change unless one of the bars actually gets longer or shorter. A frame of four bars, such as a rectangle, can fold over sideways into a slanted shape even when none of its bars bend at all. In a well-designed truss, the bars meet at joints, and the weight of the traffic is passed along to those joints, and as a result, each bar is mainly pulled along its length, which is tension, or pushed along its length, which is compression, and it is hardly bent. That arrangement allows builders to use slender bars that weigh far less than a solid beam of the same strength would.	Bridges and Trusses (Workshop)
11	A classic example is the factorial, which mathematicians write with an exclamation mark after the number. The factorial of a whole number is the product of every whole number from 1 up to it, so 4! means 4 times 3 times 2 times 1, which equals 24. Notice that 4! is simply 4 times 3!, and 3! is 3 times 2!. A recursive function can use that pattern: factorial(n) returns 1 when n is 1, which is its base case, and otherwise returns n times factorial(n minus 1). To find factorial(4), the function needs factorial(3), which needs factorial(2), which in turn needs factorial(1), and each of those calls must wait, unfinished, until the call beneath it returns an answer. That final call reaches the base case and returns 1. Then the answers travel back up the chain: 2 times 1 is 2, 3 times 2 is 6, and finally 4 times 6 is 24.	Recursion (Code & Robots)
12	Suppose each country has a single worker who divides the day evenly between the two goods: Northland makes 5 bikes and 10 shirts, and Southland makes 1 bike and 5 shirts, for a combined total of 6 bikes and 15 shirts. Now let each country lean toward its comparative advantage, so that Northland makes 6 bikes and 8 shirts while Southland concentrates entirely on shirts and makes 10 of them. Together they now produce 6 bikes and 18 shirts, which is the same number of bikes and 3 additional shirts. If they then exchange 1 bike for 4 shirts, Northland finishes with 5 bikes and 12 shirts and Southland with 1 bike and 6 shirts, so each country is better off than before. That is the whole idea in a small example. Real international trade involves many more goods and many complications, and economists point out that trade can benefit an economy overall while some particular workers or businesses lose out.

13	How does a chatbot come up with its answers? Many chatbots today are built on large language models, which are computer programs trained on enormous amounts of text. During training, a model is shown vast collections of writing and gradually adjusts a huge number of internal settings, so that it becomes better and better at one particular task: predicting what comes next. The National Institute of Standards and Technology describes the basic mechanism plainly, noting that large language models predict the next token or word in a sentence or phrase. A token is a small chunk of text, often a whole word or a piece of one, so a long word may be split into two or three tokens while a short word is usually just one. After predicting a single token, the model adds it to the text and then predicts the following one, building an entire answer gradually, step by step, from many small predictions.

How the day's picks are made

Nothing is written for the day and nothing is asked of a child. The date picks one word from each level's bank of 40 words and one fact from each level's bank (61 facts at level 1, 63 facts at level 2, 53 facts at level 3, 50 facts at level 4, 49 facts at level 5, 39 facts at level 6, 39 facts at level 7, 39 facts at level 8, 39 facts at level 9, 39 facts at level 10, 38 facts at level 11, 39 facts at level 12 and 39 facts at level 13), visiting each before any repeats. The levels are Peabody's own thirteen; the word bank covers levels 2 to 8, the fact bank levels 1 to 3.

Questions parents ask

How do I use the word of the day?

Say the word and its meaning at dinner, look for it in a book, and use it once yourself. Then see if your child spots it.

Which level should my child read?

Pick the row near the reading level Peabody shows for them. Level 2 is early readers and level 8 is a strong middle-school reader; the levels and grades page shows where each grade starts.

Is it free?

Yes, free through the end of 2026, with no sign-up.
