Our Chemical Lives:
Thousands of chemicals are used in everyday products – in our water, our food and in the air we breathe.
Units of measurement used in chemistry for length, mass and volume.
NUCLEAR CHEMISTRY Radioactivity & Radiation Alpha, Beta, Gamma Discussed are the topics of why a nucleus is unstable, what radioactivity is and how radiation is given off. The video concludes with alpha, beta and gamma radiation.
Reaction stoichiometry relates the quantities of reactants and products
Chemical Reaction and Quantities
Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically.
Why Fugu can kill you by illustrating the ideas of solutions and discussing molarity, molality, and mass percent.
Equilibrium: Crash Course
Equilibrium is all about balance and today Hank discusses Chemical Equilibrium, Concentration, Temperature, and Pressure.
Introduction to lipids, including fatty acids, triglycerides, saturated, unsaturated, phospholipids, steroids and cholesterol.
Amines and amides: naming, drawing and reactions
Understanding amino acids and their role in the Central Dogma of Molecular Biology (how the information in DNA eventually gets expressed as chains of amino acids). How amino acids are typically found as zwitterions at physiological pH.
The cofactors and coenzymes (organic cofactors) that help enzymes catalyze reactions
Vital nutrients -- water, vitamins, minerals, carbs, fats, and proteins.
Open Educational Resources (OER)
OER, a part of the global open content movement, are shared teaching, learning, and research resources available under legally recognized open licenses -- free for people to reuse, revise, remix, and redistribute. Why are OER important? High-quality OER can save teachers significant time and effort on resource development and advance student learning inside and outside the classroom. Further, open sharing of resources has the potential to fuel collaboration, encourage the improvement of available materials, and aid in the dissemination of best practices. The revolution of Open Online Learning brings great opportunities to millions of learners. However, the size of the learner population and the heterogeneity of the learners’ backgrounds make conventional one-size-fits-all educations inappropriate.
