Show your class how to rotate a figure 90 degrees clockwise around the origin of a coordinate plane. The lecturer in this video explains the concepts and steps involved in reflecting a figure across the y-axis. Consider providing this...

Bring a little magic into the classroom. Fill a cup with water, place a plate underneath it, and watch a coin disappear. This is a great way to kick off a discussion involving the behavior of light and the concepts of reflection and...

Why do bricks make terrible windows? Learn about how the different properties of matter, including transparency, reflectivity, and freezing, boiling, and melting points can help you observe what they are, as well as indicate their...

Light can be a mysterious phenomenon. Take away some of the mystery with an intriguing video lesson. The 38th lesson of the Crash Course physics series studies the movement of light waves. Topics include refraction and reflection as well...

Your young economists will learn about non-colluding oligopolies and how their reactions to each other are reflected on a kinked demand graph.

According to the video, astronomy is like a jigsaw puzzle with an infinite number of pieces. The video explains the history and invention of telescopes, how they work, refraction versus reflection, and the changing technology. It...

Explore transverse and longitudinal waves through a video lesson. Building on the previous lesson in the Crash Course physics series, the 17th lesson compares and contrasts transverse and longitudinal waves. The narrator includes a...

Equal protection under the law for every citizen—what prompted this civil right? The Fourteenth Amendment pushes individuals, as well as the Supreme Court, to examine the need for the privileges and immunities following the Civil War....

Don't flip out over the resource, but be sure to flip the figures. By watching a short YouTube video, scholars learn about reflections in the coordinate plane. They see how to identify the line of reflection given two figures.

While Mexico often gets bad press for its drug cartels, the video is a limited version of the multi-faceted country. It's ranked by the UN as one of the hardest-working countries in the world based on hours and is home to bountiful...

Demonstrate how to rotate a figure around the origin of a coordinate plane. The instructor in this video tutorial explains the concept deliberately, showing how to complete the rotation as she presents the information. After she finishes...

Pupils who view this tutorial will gain a better understanding of how to rotate a figure around the origin of a coordinate plane. This video covers how to rotate clockwise and counterclockwise to achieve the same purpose. Show this video...

Derek Owens sketches as he teaches image formation in a plane mirror. When you look at an image in a mirror, it appears as if it is behind the mirror. Mirrors create a virtual image as opposed to a real image. This educational resource...

Reflect on your knowledge of reflections. Pupils watch a YouTube video to learn how to perform reflections of two-dimensional figures over a line. The resource includes examples with a reflection over a vertical line and over a diagonal...

What exactly can we tell about an unknown substance by its properties? is the driving question of this physical science video focusing on matter. Here, scholars find the answer to the big question via investigation of what lies...

Many students experience test anxiety, keeping them from performing their best and showing what they truly know. A helpful video guides stressed-out learners through negativity bias with a set of tips and explanations to help them get...

John Green, the narrator of a Crash Course Literature episode focusing on Invisible Man, offers his analysis of Ralph Ellison's novel. Using evidence from the text, Green details why Ellison's novel should be considered as a seminal work...

Not sure how to introduce young physicists to the Heisenberg Uncertainty Principal? Well this short video is a great place to start, as it explains how the particle and wave nature of matter makes it impossible to know both the...

Finally, a lesson to brighten up the place! The 40th installment of the Crash Course physics series explores the physics of a light source. The narrator examines patterns between light and films and studies the oscillation patterns of...
