A quick demonstration of gravity and motion in this experiment with raw eggs before we cook them for breakfast. All we needed was: a toilet paper tube, a paper plate, a glass of water and a bit of curiosity.

Students will learn about the different frequencies along the electromagnetic spectrum. Vivid animation is used to explore the visible spectrum of light and the colors it allows us to see everyday. The video also investigates various...

Award Winning Short Film. Learn how the body and brain function, observe how we can dispel the stigma of mental health and see how your mental health impacts a community. This highly sensitive suicide prevention film contrasts how...

In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

Another little dancie dance for you to learn babeh! Today we work on a contemporary dance suitable for all levels of dancers, with some ooey gooey movement and allll the feelings. Hope you enjoy! Don't forget to post a clip of you doing...

En este video aprenderás qué es el código postal o zip code y para qué sirve el código postal.

This is a lecture video on the topic of wavelength and color. The video focuses on the visible light portion of the electromagnetic spectrum, which can be split into different colors. The video explains the relationship between...

The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

The Doppler Effect is demonstrated. Animations are used to show the observed change in wavelength and frequency.

This video provides an introduction to the speed of sound in air and demonstrates several methods to measure or calculate it. It also presents equations to calculate the speed of sound based on the wavelength and frequency of a sound...

👉 Learn how to identify angles from a figure. This video explains how to solve problems using angle relationships between parallel lines and transversal. We'll determine the solution given, corresponding, alternate interior and exterior....

In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...

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...

What are isonitriles good for? The Passerini reaction! This is a very neat multi-component reaction that is good for generating chemical libraries. When was it invented? What's the mechanism? What are we doing with it today? Let's find out!

The video explains the concept of redshift and blueshift in the context of galaxy movement and how it relates to the shift in wavelength of light emitted by a galaxy. The video then shows how to use an equation to calculate the shift in...

The relationship between wavelength and frequency is determined. The number of waves, wavelength, and wave speed at each standing wave frequency is determined. The wave speed is measured independent from the standing waves.

We need to know the initial velocity of a projectile leaving the Nerd-A-Pult. That means we need the initial speed and the initial angle. This video shows exactly how I measured both.

Characteristics of a Wave explores the characteristics of a wave by defining the terms wave, amplitude, crest, trough, wavelength, and frequency.

👉 Learn how to simplify expressions by dividing its terms. Remember that dividing a fraction is the same as multiplying by the reciprocal. When multiplying expressions, each individual term of the expression is multiplied to its like...

Learn how to ask questions with the French word: pourquoi (why)

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...

In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...
