Catalyst Science Hub provides simulation-based lab courses in chemistry, physics, biology, and earth science. Each experiment includes pre-lab reading, data collection, analysis questions, and a formal lab report template.
Each discipline includes lecture content, virtual labs, problem sets, and cumulative assessments.
Atomic structure, periodic trends, stoichiometry, chemical bonding, reaction kinetics, equilibrium, acids and bases, thermochemistry, electrochemistry, and organic chemistry fundamentals. Virtual labs include titrations, calorimetry, flame tests, and chromatography separations.
Kinematics, Newton's laws, work-energy theorem, momentum, rotational motion, gravitation, fluid mechanics, waves, sound, optics, electric circuits, and magnetism. Labs use virtual motion sensors, oscilloscopes, and circuit simulators to collect and analyze real data sets.
Cell structure and function, DNA replication and transcription, Mendelian and molecular genetics, evolution and natural selection, ecology and population dynamics, human anatomy systems, and microbiology. Labs cover microscopy, gel electrophoresis simulation, population modeling, and dissection.
Plate tectonics, rock cycle, weathering and erosion, atmospheric science, ocean currents, climate systems, water resources, soil science, and human environmental impact. Virtual field work includes mineral identification, topographic map reading, and weather station data analysis.
Each experiment replicates the workflow of a physical laboratory: pre-lab preparation, controlled procedure, data recording, and post-lab analysis with written conclusions.
Students read the experimental background, identify variables, and complete a safety assessment specific to the chemicals, equipment, or organisms involved. A pre-lab quiz must be passed before the simulation unlocks.
Interactive simulations model real laboratory conditions. Students manipulate variables, take measurements, and observe outcomes. Chemistry labs include burette readings and pH indicators. Physics labs include motion graphs and oscilloscope traces.
Raw data is recorded in digital lab notebooks. Students create graphs, calculate percent error, perform statistical analysis, and compare experimental results against theoretical predictions.
Formal reports include purpose, hypothesis, procedure summary, data tables, calculations, error analysis, and conclusions. Reports are graded on scientific reasoning, not just correct answers.
Dedicated modules for each AP Science exam with practice FRQs and lab-based assessment questions.
Atomic theory, molecular geometry, thermodynamics, kinetics, and equilibrium. 6 required lab investigations included.
Algebra-based mechanics, waves, and circuits. Inquiry-based labs with virtual motion sensors and force probes.
Evolution, cellular processes, genetics and information transfer, and interactions in biological systems. 13 lab activities.
Ecosystems, biodiversity, land and water use, energy resources, pollution, and global change. Field study simulations.
