Action Potential — Neuron Firing
A neuron diagram with a voltage-time graph showing all phases of an action potential. Ion animations (Na+ rushing in, K+ rushing out) are synchronized with the graph. The signal propagates down the axon at the end.

Natural Selection
A visual simulation of natural selection showing a population of bugs on a background. Camouflaged bugs survive while conspicuous bugs are removed by predators. Over three generations the population frequency shifts toward the camouflaged trait, tracked by a live bar chart.
Protein Synthesis: Transcription + Translation
A two-phase animation of the central dogma. Phase 1 shows transcription inside the nucleus: DNA unzips and mRNA is synthesized. Phase 2 shows translation at the ribosome: tRNA delivers amino acids matching mRNA codons and the protein chain elongates.
DNA Double Helix
An animated construction of the DNA double helix, starting from two parallel backbone strands and progressively adding base pairs. The structure then twists into the recognizable double helix and base pairing rules are displayed.
Mitosis — Cell Division
Step-by-step visualization of mitosis showing all six major phases. Each phase is clearly labeled and the key cellular events are animated with colored chromosomes and nuclear envelopes.
Cell as a City
An introduction to cell biology for primary school students (ages 6–11) using the analogy of a city. Each organelle is compared to a city building or service to make it memorable. Key takeaway: a cell is like a tiny city, with different parts doing different jobs.
Photosynthesis
A visual walkthrough of photosynthesis showing sunlight, CO2, and water entering a leaf and being converted into glucose and oxygen. The reaction equation is displayed alongside the animation to tie the visual to the chemistry.
