One of the most powerful moments in our courses this summer did not come from introducing a brand-new topic. It came when educators realized that a small set of foundational models could help them work through biology that often feels too complex for high school classrooms.
In Modeling the Molecular World, teachers used the Cell Modeling Kit© to model gene expression, including a “walking” Golgi as proteins moved through the endomembrane system. In another moment, that work became even more specific: educators used the same modeling system to represent an immature B cell expressing its first unique antibody in the cell membrane, with the Phospholipid & Membrane Transport Kit© and Flow of Genetic Information Kit© helping them connect membranes, proteins, and gene expression into one coherent story.
That combination changed the conversation. Instead of treating cell structure, membrane transport, and the flow of genetic information as separate units, educators experienced them as connected ideas that can help students make sense of deep immunology content. One participant described the experience this way: “The sequence of modeling kits leading from properties of water to protein folding was a great way to develop student understanding of complex concepts and structures.”
This kind of sequence fits naturally into a high school biology, honors biology, or AP Biology course as a way to deepen an existing unit on cell structure and function, gene expression, immunity, or homeostasis. It can be used as a short enrichment sequence within the core curriculum, without requiring a separate immunology unit.
Most of the educators in these summer courses teach high school biology, though several introductory college instructors were also part of the work. That matters because the value of these model pairings is not limited to advanced electives or specialty seminars. The same foundational models can support the kinds of core ideas high school teachers already teach: structure and function, information flow, membrane transport, homeostasis, and cause-and-effect in biological systems.
The Cell Modeling Kit© gives students a place to start: the overall organization of the cell and the relationships among organelles, membranes, and genetic material. That big-picture view becomes much more useful when students can then zoom in on the membrane itself and on the information that leads to protein production.
Using the Phospholipid & Membrane Transport Kit©, students can model how membranes form, how proteins are embedded in those membranes, and how transport processes shape cell behavior. Using the Flow of Genetic Information Kit©, they can trace how DNA is transcribed and translated into the proteins that later become channels, receptors, enzymes, or membrane-bound antibodies.
Seen together, those models support a much richer question than “What does this organelle do?” They help students ask how a sequence in DNA becomes a protein, how that protein is processed and positioned in the cell, and how those molecular decisions shape what the cell can do.
This summer, one especially powerful example centered on immunology. Educators began with gene expression in the Cell Modeling Kit© and followed the movement of proteins through the cell, including the role of the Golgi apparatus in processing and trafficking them. From there, the model sequence expanded into a more detailed representation of an immature B cell expressing its first unique antibody in the plasma membrane.
That is a sophisticated idea, but the modeling sequence made it more accessible. The cell model held the big picture. The membrane model helped educators think about how a protein becomes part of the membrane. The genetic information model helped them connect that protein back to the sequence-based processes of transcription and translation.
For teachers, this kind of experience reinforces an important planning idea: students do not always need a brand-new unit for every emerging topic. Sometimes they need a well-chosen set of foundational models that can be revisited and recombined as the biology gets more complex.
One educator's response captured that broader value clearly: “Absolutely—got my curiosity going and thinking about how the kits can be used in my classes and possibly modified.” Another participant wrote, “All of the varied models… about how cellular structures function together. I learned how to use models more effectively and different ways to scaffold them into my curriculum.”
A shorter but equally revealing example came in courses where educators explored anthrax toxins and the A/B system involved in infection. Here again, the Cell Modeling Kit© helped participants work through their questions, apply what they already knew, and generate new questions about how toxins enter cells and disrupt cellular processes.
That work did not stand alone. Earlier experiences with the Water Kit©, the Phospholipid & Membrane Transport Kit©, and the Amino Acid Starter Kit© gave educators background they could draw on as they reasoned through a more complex story about protein structure, membrane interaction, and cellular entry. One participant summarized that experience simply: “Tim’s storytelling and then demonstrating how the anthrax gets into the cell with the kits.”
This is part of what makes foundational models so useful. They help students and teachers build transferable understanding. Instead of mastering one isolated activity, they develop ways of thinking that can travel from membrane transport to immunity, from protein folding to infection, and from one phenomenon to the next.
For high school teachers, the practical implication is not that every class needs a full immunology or toxin case study. The implication is that a strong set of foundational models can make advanced or current biology more teachable because students already have tools for thinking about cells, membranes, proteins, and genetic information together.
A sequence like this might begin with whole-cell structure, move into membrane organization and transport, and then return to the question of how specific proteins are produced and positioned in the cell. Once students have that foundation, topics that might otherwise feel out of reach become much more approachable.
In an immunity unit, a teacher could use this framework after students learn the basic immune response to help them understand why receptor proteins on cell membranes matter for recognizing pathogens and activating defenses.
In a homeostasis unit, students could connect membrane transport and protein function to how cells maintain internal balance, such as through pumps, channels, and signaling proteins. This fits naturally after a cell structure and function sequence, especially when students are asked to explain how cells regulate movement across membranes.
In a gene expression unit, an AP Biology teacher could extend beyond the central dogma by asking students how a gene’s protein product ends up in the correct location and what happens when that process fails.
This summer’s work reinforced a growing realization: foundational models can do far more than support isolated lessons. Used in combination, they can help educators make sense of current research topics and bring that kind of reasoning into the classroom in ways that are flexible, rigorous, and adaptable across many storylines.
That is one reason this line of work is so important moving forward. When students can connect cells, membranes, proteins, and genetic information as part of one story, they are in a much stronger position to understand the biology behind health, disease, and new discoveries.
