Project: Design a Galvanic Cell
Students use a voltage sensor and a variety of supplies to design a galvanic cell that can light LED bulbs in series or in parallel.
Research Enhancement: Galvanic Cells
Students research, discuss, and write about the pros and cons of moving towards homes and cars fully powered by rechargeable batteries.
Half-Lives
Students model radioactive decay to determine the half-life of a “radioactive” sample.
Bonding and Organic Chemistry
Students use the Molecular Model Set to explore the variety of bonding configurations possible by a carbon atom.
Distilling Aromatic Compounds
Students use a condenser to extract an aromatic distillate from a spice sample.
Fragrant Esters
Students use a temperature sensor and a Molecular Model Set to study the properties of reactants and products of three distinct esterification reactions.
Polymers
Students investigate a polymerization reaction and compare the properties of polymers with varying degrees of cross-linking.
Amino Acid to Protein
Students use a Molecular Model Set to explore amino acids and a polymerization reaction where amino acids are joined to build a “protein”.
Chlorophyll Extraction
Students use a colorimeter to investigate which wavelengths of light are best absorbed by green plants.
Respiration and Energy
Students use a Pressure Sensor to explore the effect of different energy sources on the respiration rate of yeast cells.
