Plasmolysis
Students use a conductivity sensor to explain the results of different concentrations of salt water on plant tissue before they design an experiment to...
Osmosis
Students use a colorimeter to determine which extracellular fluid is hypertonic to a model cell and which solution is hypotonic.
Diffusion
Students use a pH sensor to investigate the diffusion of hydrogen ions through a semipermeable membrane, comparing the rates of diffusion for two solutions...
Enzyme Activity (Oxygen)
Students use an oxygen gas sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Enzyme Activity (Pressure)
Students use a pressure sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Fermentation
Students use an ethanol sensor to determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation.
Introduction to Materials Tester
This is a general introduction to PASCO's Material Testing Machine (ME-8236) to show how to set up the machine, make measurements, and use accessories.
Compliance Calibration Tutorial
This tutorial takes you through all the steps of calibrating the Material Testing Machine.
Tensile Testing
In this lab, brass will undergo a tensile test. Quantities measured include Young’s Modulus, Yield Strength, Tensile Strength, Ductility, and Modulus...
Young's Modulus
In this lab, students will collect stress vs. strain data for a test sample in the elastic region. Several runs will be taken for the same sample to calculate...
