Our approach to character lighting.
Character transformation and their needs.
In this video we show you how to craft the chassis for the Bit-zee using a $3 piece of Lexan and tap light housing. Created by Karl Wendt.
This video shows how Bit-zee's shell was modified to allow space for the bumper switches. Created by Karl Wendt.
Learn how to use jQuery to check that the webpage is fully loaded before you try to access and modify the DOM.
Chemical bonds are the glue that hold molecules together. We will learn about the different kinds of bonds, ways chemists draw bonds and molecules, and how the type of chemical bonding affects the bulk properties of a material. We will cover electronegativity, Lewis dot structures, VSEPR, bond hybridization, and ionic, covalent, and metallic bonds.
Many chemical reactions are reversible, and the forward and backward reactions can occur at the same time. When the rate of the forward reaction is equal to the rate of the backward reaction, we call that a dynamic equilibrium. We will learn how equilibrium can be described by the equilibrium constant K, and how different factors than can affect the chemical equilibrium.
We are now going to delve into the heart of chemistry. We learn ways of representing molecules and how molecules react. To do this, we'll even think about "how many" of a molecule we have using a quantity called a "mole".
Kinematic equations help solve for an unknown in a problem when an object has either a constant velocity or constant acceleration. This video will help you choose which kinematic equations you should use, given the type of problem you're working through.
How homologous chromosomes exchange fragments in prophase I. Tetrads, chiasmata, and alleles.
Overview of DNA transcription, translation, and replication during mitosis and meiosis. Learn about chromosomes, chromatids, and chromatin.
Discussion of the relatively recent changes in our ability as a species to shine light on our deep past. Created by Sal Khan.
Adafruit founder Limor Fried and virtual reality designer Nat Brown show how simple logical circuits underlie everything your computer does.
Definition of circuit terms: element, component, node, branch, mesh, and loop . Created by Willy McAllister.
Introduction to the circulatory system and the heart.
Pamela encourages you to use comments to make your code clearer and easier to understand.
In this video we show you how to connect Spider's motors to his tap light base. Created by Karl Wendt.
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
