Water properties, biological macromolecules, and the chemistry that makes life possible
Organelles, membrane transport, and how cells maintain homeostasis
Explore each organelle's structure and function through interactive 3D models and cellular case studies.
Model water potential, tonicity, and membrane transport using virtual potato cores and dialysis tubing.
Discover why cells stay small by modeling diffusion rates across cube-shaped cells of different sizes.
Enzymes, photosynthesis, cellular respiration, and energy flow in living systems
Test how temperature, pH, and substrate concentration affect catalase activity. Graph initial rates and apply Michaelis-Menten reasoning.
Measure photosynthesis rate using floating leaf disks under varying light intensity and CO₂ levels. Includes simulation, class dataset analysis, FRQ, and 10-question mastery quiz.
Use simulated respirometers to compare oxygen consumption in germinating vs. dormant peas at different temperatures.
Signal transduction, feedback mechanisms, mitosis, and meiosis
Mendelian genetics, inheritance patterns, and chi-square analysis
DNA replication, transcription, translation, and operons
Step through semiconservative replication, leading/lagging strands, and the roles of helicase, polymerase, and ligase.
Transcribe DNA into mRNA, translate codons at the ribosome, and predict the effect of point mutations.
Toggle inducers and repressors to model bacterial gene regulation in real time.
Evolutionary mechanisms, Hardy-Weinberg, and phylogenetics
Run multi-generation populations and watch allele frequencies shift under selection, drift, and migration.
Compare fossil records, homologous structures, embryology, and DNA sequences across species.
Build cladograms from molecular and morphological data and interpret common ancestry relationships.
Population dynamics, community ecology, and ecosystem energy flow
Investigate taxis vs. kinesis using wet/dry and light/dark choice chambers. Run a chi-square goodness-of-fit test, analyze a case study, and tackle FRQ + mastery quiz.
Compare exponential and logistic growth, model carrying capacity, and predict predator-prey cycles.
Build food webs and trace the 10% rule through producers, consumers, and decomposers.
Calculate species richness and evenness across sample sites and connect biodiversity to ecosystem stability.
