Safety First
Goggles, gloves, ventilation, small quantities, labels, and adult supervision. Never taste or inhale chemicals.
Periodic Table Image
Show the full AETHRA periodic table image: groups, periods, elements, symbols, and atomic numbers.
Periodic Table Lesson
Learn elements, atomic number, groups, periods, metals, nonmetals, and reactivity trends.
pH Testing
Use cabbage indicator or pH strips to compare acids, bases, and neutral solutions.
Filtration
Separate solids from liquids using filter paper, coffee filters, sand, charcoal, and gravity.
Crystallization
Grow crystals while learning solubility, saturation, evaporation, and nucleation.
Density
Measure mass per volume and observe how matter separates according to density.
Heat Transfer
Compare conduction, convection, radiation, insulation, and temperature change over time.
Fermentation
Observe yeast converting sugar and producing carbon dioxide. Connect to food science and biofuels.
Distillation
Study separation by boiling point. Use classroom-safe demonstrations only.
Material Testing
Compare plastics, metals, rubber, wood, and composites for flexibility, hardness, and heat response.
