Where does a buyer's demand curve come from? A rational buyer wants to get as much "bang per buck" from their consumption as possible. In economics, that's called marginal utility per dollar spent. When the price of a good decreases, the "bang per buck" on that good increases, which incentivizes consuming more of it. In this video, we derive the individual's demand curve for a good by tweaking the marginal utility per dollar spent. Created by Sal Khan.

Walk through the logic of determining what kind of good has the most elastic demand in this video.
There are several factors that affect how elastic (or inelastic) the price elasticity of demand is, such as the availability of substitutes, the timeframe, the share of income, whether a good is a luxury vs. a necessity, and how narrowly the market is defined. We explore each of these in this video.
Microbiology is the study of microorganisms, which are tiny organisms that can only be seen with a microscope. Microorganisms include bacteria, viruses, fungi, and protozoa. Microorganisms are found everywhere in the environment, including in water, soil, air, and in the bodies of plants and animals. Microbiology is an important science that helps us to understand how microorganisms interact with each other and with their environment. Microbiology also helps us to understand how microorganisms can cause disease and how they can be used to produce food and medicines. Teaching microbiology can be a fun and interesting experience for students. There are many different ways to teach microbiology, and the best way to teach it will depend on the students’ age and level of education. One way to teach microbiology is to use learning materials that are specifically designed for schools. These materials can help to make the learning process more fun and interesting for students. Some of the best practices for developing microbiology learning materials for schools include: 1. Developing materials that are age-appropriate 2. Using fun and interactive activities 3. Incorporating images and videos 4. Using real-world examples 5. Including assessment questions
