Learn Sound and Light for Kids | Round-Up Lesson | Kids Academy If you want to learn sound and light then you are at the right place as we will guide you through it all. Sound: The sound is a type of energy that is produced when...

In this video Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.

Let's learn about the 7 wonders of the world!

This problem was given to Primary 6 (age 11-12) students in Singapore. What is the area of the shaded region in the video, which consists of the region bounded by 4 quarter circles in a 3x3 grid of squares, and each square has a side...

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from?

Waves transfer energy from one place to another. You should already know how to describe them in terms of frequency, wavelength and amplitude In this video we’re going to look at the two ways they can be classified. Waves are produced as...

Under the leadership of Lisa Jackson, Apple's environment and social VP and former head of the EPA, the company is already carbon neutral within their own corporate and retail boundaries. By 2030, Apple hopes to extend carbon neutrality...

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction,...

A quick craft using kitchen foil to make a dream come true toy for Max.

This video is a lesson about sound and how it works. It covers topics such as the definition of sound, how sound is produced through vibrations, the different types of waves (transverse and longitudinal), the speed of sound in different...

Explore the quirky world of penny-farthing racing with UK champion Richard, whose passion reignites a bygone era.

Learn about the different types of waves, including transverse and longitudinal waves. Understand how these waves move through different mediums and their properties. Discover the speed of sound and how it varies depending on the...

Why can you see your reflection in some objects? In this video we will look at ray diagrams for reflection, refraction and colour absorption. Visible light is part of the electromagnetic spectrum. Light is a transverse wave, and travels...

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

Waves are vibrations that transfer energy from place to place without matter being transferred. Think of a Mexican wave in a football crowd: the wave moves around the stadium, while each spectator stays in their seat only moving up then...

Learn how to write the equation of hyperbolas given the characteristics of the hyperbolas. The standard form of the equation of a hyperbola is of the form: (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1 for horizontal hyperbola or (y - k)^2 / a^2...

In this video Paul Andersen describes some of the properties of waves. He starts be identifying particles and waves as the only phenomenon that can transfer energy from place to place. He identifies the defining characteristics of...

A lot of people with coughs or fevers might be stressing out these days because they are worried that they have COVID-19. But with cold and flu season still in full swing, and the spring allergy season starting up (in the Northern...

This program explores the fascinating features of vibrations and waves. Vivid examples of these phenomenon help students understand how sounds are formed, how light travels, and how ocean waves move. Special attention is also given to...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...
