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...
How a Greenhouse Works: Light
In this lab, students use a light sensor to determine how light or brightness depends on the angle at which the sun’s light strikes the surface of the...
How a Greenhouse Works: Heat
In this lab, students use a temperature sensor to measure the heat generated in a model greenhouse by altering the types of material that light passes...
Enzyme Action (PASPORT sensors)
Use a PASPORT oxygen gas sensor to understand how optimal environmental conditions, such as temperature, play a key role in enzyme function. Note: This...
Membrane Permeability (PASPORT sensors)
Use a PASPORT pH sensor to explore the permeability of a cell-like membrane to hydrogen (H+) and...
Organisms and pH (PASPORT sensors)
Use a PASPORT pH sensor to determine how effective various substances are at buffering large changes in pH. Note: This investigation has been updated for...
Osmosis (PASPORT sensors)
Use a barometer/low pressure sensor to explore the concept of cell membranes and how water and other substances pass through a membrane through the process...
