Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

For free. For everyone. Forever. #YouCanLearnAnything

A surprising story from the AI industry: **Boris Cherny**, the head of Claude Code at **Anthropic**, briefly left the company to join **Cursor**—and then returned just two weeks later.

In this video, we break down why Boris made the move, what he discovered after joining Cursor, and why he ultimately decided to go back to Anthropic. While he admired Cursor’s product and team, he realized something important was missing: the mission.

At Anthropic, the focus on **AI safety** drives everything. For Boris, that shared mission was a major reason he joined in the first place. Without that deeper purpose, even working on an exciting AI coding product didn’t feel the same.

His quick return highlights an important lesson in tech and career choices: sometimes the **“why” behind the work matters more than the work itself**.

Was this the fastest job reversal in AI? Maybe. But it also raises a bigger question about purpose, mission, and what really keeps people motivated in the fast-moving world of AI.

What do you think — is mission everything, or is it overrated?

In 1789, the French Monarchy's habit of supporting democratic popular revolutions in North America backfired. Today, we're talking about the French Revolution. Across the world, people were rising up to throw off monarchies, and Louis didn't see the writing on the wall until it was too late. Today we'll talk about how the French Revolution unfolded, and what (if anything) was really accomplished. You'll learn about stuff like the National Assembly, the Tennis Court Oath, the Declaration of the Rights of Man and the Citizen, the guillotine, Robespierre, and a bunch of other kind of unbelievable details.

What is the difference between something that is alive and something that is not? You and your kids will learn all about the characteristics of both living and non-living things. Both have special characteristics that differentiate the two groups. Living things grow, eat, and reproduce. They can also breathe, have senses, and move. However, some non-living things can move, too. Think about fire or water. They aren't alive, but they definitely move!

Things that are alive grow, such as chicks that become hens or sprouts that become plants. They also have to eat, or take in nutrients, to survive. Different species need different nutrients, but they all require nutrients to live and grow. And both plants and animals reproduce to create more of their own kind. Non-living things can't do any of these things.

In addition, things that are not alive also do not breathe or have senses. For instance, a teddy bear cannot feel you touch it. A waterfall cannot see anything. However, some of these objects do move. As mentioned, fire and water aren't alive, but they move all on their own. Other things, like cars, can move as well, but not on their own. These objects require people to make them move. In addition, non-living things can be solids, liquids, or gases.

We hope you and your student(s) enjoyed learning about what determines if something is alive! If you want even more information, head over to our website and download one of our many free lesson plans, full of activities, worksheets, and more!

Because young children have an interest about the world around them and want to know how things work, science is a subject that is captivating for young students in Preschool and Kindergarten. Here at Kid’s Academy, we explain the concepts of sound and light clearly and easily and students can’t help but want to learn more! In the videos, teacher Andrew and the fun cartoon character, Ball-y, explain these concepts with light and sound experiments for Kindergarten and 1st grade.

This series of videos teaches students what sound and light are as well how sound and light are made. In addition to teaching that sound and light are energy, there are experiments for kids that the videos demonstrate for the children to see and do on their own. Students may not understand how sound waves travel. The videos show sound wave experiments to explain this concept. Pluck a guitar string and see the vibrations, or watch how rice on a baking sheet vibrates when held over a speaker playing loud music. Other sound experiments for students include listening to sounds and trying to guess what makes the sound.

Students also learn how we use sound and light to communicate. When discussing light, students learn that traffic lights, lighthouses, and lights on radios, phones and appliances all tell us something. Sounds communicate to us too. Doorbells, sirens, school bells and whistles use sound to convey a message. Do sound experiments for kids and brainstorm other ways that light and sound communicate to us! Or, think of new ways that sound and light can be used.
Kid’s Academy includes a review video that teachers use to summarize the concepts in this lesson series. The review video defines light and sound again, shows how light and sound travel to our eyes and ears and then to our brain, and gives examples of light and sound.

When incorporating these science videos into your classroom, the concepts of sound and light are clearly explained. The videos show experiments for kids that encourage and engage students to learn and explore their world!

Astronomers think there should be 5 times as much dark matter as ordinary matter – a shadow universe that makes up most of the mass in the universe. But after decades of trying, no experiments have found any trace of dark matter – except one.
