Do you remember having a cold in 5th grade? Or the flu a couple years ago? Your immune system does. Our bodies hold many levels of immune defense.Physical barriers like skin, the innate immune system, and our body’s most powerful defender, the adaptive immune system. Millions of B cells and T cells and antibodies are constantly on patrol for germs and antigen invaders. As scientists learn more about how this system works and how to engineer it, could we ever actually be immune to everything?

This chemistry video tutorial discusses the relationship between cell potential and gibbs free energy. It contains plenty of examples and chemistry practice problems. It discusses the signs of the potential energy and delta G in determining if a reaction is spontaneous or nonspontaneous. The system is in equilibrium whenever delta G and E is equal to zero. This video discusses Faraday's constant which relates the electric charge to moles of electrons per mole of substance. 1 volt is 1 Joule per coulomb. voltage is a measure of electrical potential energy per unit charge. delta G represents the maximum amount of electrical work that can be performed by a reaction. This tutorial contains problems where you have to find the value of n in order to use it in the equation delta G = -nFE. To find it, you need to balance the half reactions and make sure the moles of electrons are the same using the least common multiple rule. In addition, you need to calculate the cell potential of the net reaction using the standard reduction potential of the half reactions. This lesson is basically a section in electrochemistry.

After serial photography became a thing, it wasn't long before motion pictures started to develop. And, at the front of that development was Thomas Edison, who you may know as an inventor and business person. In this episode of Crash Course Film History, Craig talks to us about Edison, his assistant W.K.L. Dickson, and their inventions that pioneered motion pictures.

In July of 2021, Robert “Robby” Asberry took over as the new superintendent of Hancock County Schools, a small district in Hawesville, Kentucky. Driven by the negative academic effects of the pandemic on students and his own son’s struggles with reading, Asberry made overhauling the district’s literacy instruction one of his first priorities. Here’s what happened next.

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish ladder to get over a dam. They first brainstorm their own ideas, and then learn about existing ways engineers have made dams "friendlier" to migrating fish, before being quizzed as part of the game.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).
