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.
Greenhouse Gases
Students use a temperature sensor to investigate how changing the composition of air affects the rate at which its temperature will increase when energy...
The Water Cycle
Students use a turbidity sensor, a conductivity sensor, and a condenser to explore how energy drives the movement and purification of water through Earth’s...
