This 14-minute video lesson looks at 3 basic differential equations that can be solved by taking the antiderivatives of both sides.
In this video, we use direction fields (drawn as quiver plots) to illustrate the numerical integration of differential equations. We include a heuristic example of how one might try to adapt step size by comparing different orders of approximation.
In the first video, we present a biological circuit topology from Ma, Trusina, El-Samad, Lim, and Tang, "Defining network topologies that can achieve biochemical adaptation," Cell, 138: 760-773 (2009). This topology supports adaptation, which is not the absence of change in response to stimulation/stress, but, instead, the ability to produce delayed compensation for those changes. In the second video, we summarize the method of almost linear stability analysis used to solve for the dynamics of this example system.
To describe how oscillations are supported in systems of differential equations, we present a classic "Romeo and Juliet" picture of two-dimensional oscillations, and we analyze how trajectories change as nullclines are arranged at different angles in the phase plane. In addition to models based on traditional systems of differential equations, dynamical systems with time delays and dynamical systems with stochastic fluctuation (i.e. stochastic resonance) can also support oscillations.
In the five parts of this video, we define the derivative and then build a cribsheet of rules for expressing the slopes of simple functions and combinations of functions. These include the power rule, the chain rule, the product and quotient rules, and the rules for differentiating sinusoidal functions.
The first video segment presents a canonical mathematical example from quantitative biology, in which mRNA is transcribed from a gene sequence, and protein is translated from mRNA. The second segment uses eigenvector-eigenvalue analysis to sketch the trajectories of the system in a phase portrait. Finally, the third segment generalizes the linear stability analysis used to study this example.
To reinforce students' understanding of the human digestion process, the functions of several stomach and small intestine fluids are analyzed, and the concept of simulation is introduced through a short, introductory demonstration of how these fluids work. Students learn what simulation means and how it relates to the engineering process, particularly in biomedical engineering. The teacher demo requires vinegar, baking soda, water and aspirin.
The digestive system is amazing: it takes the foods we eat and breaks them into smaller components that our body can use for energy, cell repair and growth. This lesson introduces students to the main parts of the digestive system and how they interact. In addition, students learn about some of the challenges astronauts face when trying to eat in outer space.
In this video we introduce the digestive system. We look at the two types of digestion: mechanical digestion and chemical digestion. We also look at the two subdivisions of the digestive system: the digestive tracts and the accessory structures.

The mouth is our first stop in our digestive system. It is made of our cheeks, lips, tongue, and teeth. We take a look at the mouth as well as the components and how they help with the digestion of food.

Moving down the digestive system we take a look at the throat. Specifically we examine the pharynx, and the esophagus. We also look at how we swallow, breaking it down into the two phases.

A read-aloud of Patricia PolaccoŐs "Thank You, Mr. Falker" helps promote deeper comprehension through questioning to achieve personal connections and discussions of character and theme.
This lesson, in which students research worms in order to create a classroom habitat, incorporates reading and writing across content areas as well as math and science activities.
Digital cameras are part of the aresenal of tools web designers need to use to produce oriignal images on web sites. Although many types of cameras are available, there are common elements in their use that are important for developing a sound foundation in the design of a web site.
A quick video on what is digital citizenship?
Common Sense Education offers free pre-built lessons for K-12 surrounding digital citizenship and staying safe online. Their lessons include a teacher's guide, lesson slides, activities with answer keys, videos, and songs for younger grades to help deliver the lesson. Teachers do need to create an account in order to access the lessons but it is free and you have total access once you sign up. I personally use this in connection with my Media Studies course and love the lessons that they offer. Super simple, and relevant to the students and their interactions online. They also offer a tips sheet and a parent connection sheet for each of their small themed units.
