👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A...

The video is about using radar diagrams (also known as ray diagrams) to investigate how the type of lens used and the distance between the lens and object affect the formation of an image. The video shows four different ray diagrams,...

The video explains the basics of electromagnetic waves, including their definition as transverse waves that transfer energy from a source to an absorber. It discusses the seven general sections of the electromagnetic spectrum, going from...

On Aug. 26, 2020, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that turned out to be one for the record books – the shortest gamma-ray burst (GRB) caused by the death of a...

👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

Scientists have mapped the environment surrounding a black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space...

The video discusses the different ways in which waves behave when they encounter a boundary between two materials. The behavior can either be reflection, absorption, or transmission or a combination of the three. The video also explains...

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

It was Marie Curie who first used the word radioactive to describe a phenomenon discovered by Becquerel in 1896. It...

Introducing angles in two-dimensional figures.

Planetary scientists believe that small impacts regularly bombard the Moon, but until recently, they’ve had no way to distinguish new craters from the already pockmarked lunar surface. In 2009, NASA’s Lunar Reconnaissance Orbiter...

Doodle Science teaches you high school physics in a less boring way in almost no time!

Medical Imaging | Waves | Physics | FuseSchool If only we were all given a window so a doctor could look inside us when we were ill.Think of the operations that would save! Luckily there are now many ways we can see what is happening...

This video provides an introduction to the structures and actions of two different types of lens - convex and concave lenses. The video also explains the focal length of each type of lens and how to obtain the principal focus for each.

👉 Learn all about points lines and planes. In this playlist, we will explore how to how to identify, write, label all points lines, and planes. We will learn how to determine the distance between two points as well as the midpoint. Learn...

It's time to check out Group 2 on the periodic table, the alkaline earth metals. This includes beryllium, magnesium, calcium, strontium, barium, and radium. What can we say about their properties, reactivities, and applications? Let's...

This nugget defines an angle and shows how an angle is formed. It also describes the various parts of an angle.

A lens is a piece of transparent material, like glass, that uses refraction to form an image by changing the direction of light. There are two types of lens; converging and diverging. Converging lenses are shown using this symbol. The...

This video explains the technical process behind the formation of images in plane mirrors, and justifies the characteristics of those images. It covers the laws of reflection, the formation of point images, and the fact that the image in...
