In courses and programs with community-sponsored or industry-sponsored projects, the handoff between the design team and the sponsoring partner is a particularly vulnerable transition. Innovations with the potential for impact fail shortly after the handoff for myriad reasons, including: inadequate resource allocation (time, money, skills); no clear institutional champion; inadequate institutional will to see the concept through further trial, iteration, and growth; and more. What might it look like to design the handoff? This lesson prompts design students (high school through graduate school) to begin a design project within a design project: to empathize with the handoff’s stakeholders; to define the handoff’s key needs and opportunities; to ideate novel handoff artifacts, strategies, and processes; to prototype improvements to their intended handoff strategy; and to test these strategies before the class or program ends so they can make adjustments and improvements.

In this deterministic cellular automata model, interactions between neighboring automata are described using a prisoner's dilemma. Limiting dispersal of seeds of annual plants can permit heterogeneous co-existence, whereas thorough mixing instead allows one subpopulation to dominate quickly.

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

Determine the dew point temperature for your classroom through a hands-on experiment. Use humidity and temperature probes to investigate the temperature at which it would rain in your classroom! Learn about water density and the conditions necessary to produce fog or rain.

These slides provide a brief overview of some of the problematic histories and legacies of the Dewey Decimal Classification System (and Dewey himself), particularly focusing on heterosexism and cissexism, but also sexism, racism, colonialism, and more discrimination. They critique the idea that libraries and librarians are neutral, discuss some of the creative and caring ways library workers and communities have challenged and continue to challenge and change these systems, and suggest ways we can all challenge discrimination in library classification (and other systems, policies and practices) too and why it is important that we do so.

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.

Movement of ions in and out of cells is crucial to maintaining homeostasis within the body and ensuring that biological functions run properly. The natural movement of molecules due to collisions is called diffusion. Several factors affect diffusion rate: concentration, surface area, and molecular pumps. This activity demonstrates diffusion, osmosis, and active transport through 12 interactive models.
