Time passes for all of us at the same rate of one second per second. But why does it sometimes feel like time is passing so fast, or so slowly? Especially during COVID? Let’s learn about how our brains keep track of and try to make sense of time, and how they get fooled.

What are you waiting for? Eclipses
Hello friends. In this educational video for kids we are going to learn about eclipses. There are two types of eclipses, a solar eclipse and a lunar eclipse, but first of all, do you know what an eclipse is?
An eclipse occurs when an astronomical object is temporarily obscured. Sometimes the Earth is placed between the sun and the moon and other times the moon is situated between the Earth and the sun. These are eclipses… but let’s investigate it better.
The lunar eclipse is when the Earth is situated between the moon and the sun making the Earth block out the sun’s rays which would be shining on the moon, creating a shadow and darkening it. This phenomenon allows us to see the moon in a reddish color…almost as if it were bleeding.
Lunar eclipses are quite frequent and can be seen from any part of the world at night time. They last various hours and can be different types, though the most frequent ones are the partial lunar eclipse and the total lunar eclipse.
When there is an eclipse and it looks as if someone has taken a bite out of the moon, it is a partial eclipse, and when there is an eclipse and one can see the whole moon, it is a total eclipse. Easy don’t you think?
By the way, to observe a lunar eclipse one doesn’t need anything special, a normal telescope or binoculars would do.
Solar eclipses only occur when there is a new moon, and is seen when the moon is in between the Earth and the sun. The moon hides all the suns light or at least part of it.
Solar eclipses can be of different types: total, partial or annular.
A total solar eclipse is when the moon hides all of the suns light and the sun’s face disappears behind the moon. In the middle of the day, it would seem as if night has fallen. The sky darkens and stars appear. Many animals, think it’s night time and go to sleep, and nocturnal animals such as this owl, begin their day, actually their night, not understanding that in a short time the sun will reappear.
Partial solar eclipses occur when the moon comes between the Earth and the sun, but not completely, leaving part of the sun visible. The day becomes slightly darker and the sun resembles a cookie with a chunk missing.
An annular solar eclipse occurs when the moon hides only the middle part of the sun. It is seen as a black circle surrounding a bright ring. It looks like a ring, doesn’t it?
By the way and this is really important, it is very dangerous to observe solar eclipses without special eye protection. Please remember this as it is extremely harmful.
Well now we know a little bit more about eclipses…don’t you think it is fascinating learning new things?
Goodbye friends, we hope you enjoyed this educational video for children about eclipses. Don’t forget to subscribe to Happy Learning TV, so you don’t miss any of our videos.

One of the most famous swords was the Cutlass, used by naval men for centuries but made famous by pirates.
The overall build of the Cutlass made it extremely popular among seafarers in the 17th and 18th centuries.
As a short broadsword, generally around 28 inches in length, the Cutlass was ideal for use on ships, where space was limited.

In which John teaches you about the Seven Years' War, which may have lasted nine years. Or as many as 23. It was a very confusing war. The Seven Years War was a global war, fought on five continents, which is kind of a lot. John focuses on the war as it happened in the Americas, Asia, and Africa. the "great" European powers were the primary combatants, but they fought just about everywhere. Of course, this being a history course, the outcomes of this war still resonate in our lives today. The Seven Years' war determined the direction of the British Empire and led pretty directly to the subject of Episode 28, the American Revolution.

Do you know what an abbreviation is or how to make one? An abbreviation is a shortened form of a word or phrase. You can make one by taking letters out and replacing them with other letters or symbols, such as a period. In this video, you and your kids will learn about some common abbreviations, many of which you probably use every day.
One of the most common abbreviations has to do with the time of day. We use a.m. in the morning hours and p.m. in the evening and night hours. What do those actually stand for? "Ante meridiem" is Latin for before noon, so we use a.m. for all the times before noon. "Post meridiem" is Latin for after noon, so we use p.m. for all the times after noon.
Other common abbreviations involve days of the week, months of the year, measurement, and time. For example, we can write Sat. for Saturday or Dec. for December rather than writing out the whole word. In recipe books, you will often find abbreviations for their measurements, like tsp for teaspoon or oz for ounce. And you've probably seen abbreviations like min for minutes or yr for year.
We hope you and your student(s) enjoyed learning about abbreviations! If you want even more practice, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

↓↓↓ More info and sources below ↓↓↓
Seemingly distant ecosystems, even half a world apart, are connected in surprising ways. In this special limited series, Emily Graslie and Trace Dominguez join me as we explore the universal rules of life that tie together Earth’s living systems. In episode 3, we look at ecosystems at their largest and smallest scales of time and size from the Serengeti to Andrews Experimental Forestin Oregon. How does the cycling of nutrients and molecules make life possible on Earth? Who are these recyclers and scavengers? Sometimes this recycling happens fast and violently, and sometimes it happens slow and beautifully.
In Our Nature is a special miniseries produced by It’s Okay To Be Smart for PBS. Stay tuned for more episodes coming this summer, here on our YouTube channel!

Welcome to the 2024 K12 Robotics Competition!
This year, we invited students in grades 4–12 to join the K12 Robotics League. Students worked in teams of two or three, with guidance from their instructors, and participated in two virtual qualifying rounds. Teams competed against others in their grade bands (4–6, 7–9, and 10–12) and skill levels (intermediate and advanced).
Today, we celebrate the top teams from the qualifying rounds as they compete for the national championship! Congratulations to all the students participating today—you’ve demonstrated incredible creativity, problem-solving skills, and coding expertise. Be proud of your achievements and enjoy this exciting culmination of your hard work!
Let the bot battles begin!

Why do we have sunny weather one day and heavy rain the next? Large air masses cause some of our weather. There are four main fronts caused by these air masses.
A cold front which is the result of cold air
A warm front which is caused by warm air rising over cold air.
An occluded front which is a warm air mass stuck between two air masses.
A stationary front which is two air masses with almost the same density and pushes against each other.
