How Science Got Us to 2020 | Compilation
As we forge ahead into the new year, let’s take some time to thank the intrepid researchers, volunteers, and even the occasional dog who came before us, made sure our food and drugs are free from poison, and built the devices that make...

Optical Isomerism: The Chemistry of Mirror Images
Optical isomerism occurs in molecules that are chiral, meaning they cannot be superimposed on their mirror images. These isomers, known as enantiomers, differ in their optical activity—they rotate plane-polarized light in opposite...

Congruent Figures and Lines of Symmetry
Mr. Addit defines the terms: congruent figures and lines of symmetry. He then models how to determine if figures are congruent and where lines of symmetry can be drawn.

Symmetry
Symmetry defines symmetry and lines of symmetry and separates a group of shapes into two categories: symmetrical and nonsymmetrical.

Organization and Symmetry in Kingdom Animalia
How are the contents of animals organized? How does this differ from animal to animal? Are all animals symmetrical, and in the same ways? Just a bit more information to get through before diving into all the animal phyla, I promise!

Exploring Reflections in Linear Equations
In this lesson, students will learn about reflections in linear equations. They will explore how the functions F of X and G of X are alike and different, focusing on the slope and Y-intercept. Through examples and a table of values,...

Isomers: Stereo (Chiral)
In the 50s and 60s, pregnant women were prescribed Thalidomide, a stereoisomer that prevented morning sickness but caused severe birth defects. The instructor in the videos explain stereoisomers, enantiomers, and chirality using...

Converging Lenses
Did you know your eyes can only focus to within about six inches in front of them? The video explains converging lenses, refraction, images, the difference in converging and diverging, focus, focal length, and ray diagrams.
