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...
Peppered Moths Graphing Activity
How do genetic traits help or hurt organisms when environmental changes occur? See how you can use SPARKvue to help with analysis of data in a table.
Enzyme Activity (Oxygen)
Students use an oxygen gas sensor to investigate the catalyzed decomposition of hydrogen peroxide by catalase.
Mathematical Modeling of Evolution
Students work with a mathematical model and computer simulation to explore how inheritance patterns and gene frequencies change in a population.
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.
What Factors Affect Dissolved Oxygen?
Students will use a dissolved oxygen sensor to determine how different factors affect the concentration...
Plant Respiration and Photosynthesis
Students use a carbon dioxide sensor to measure the rates of photosynthesis and respiration in spinach leaves.
Enzyme Activity (Oxygen)
Students will use an oxygen gas sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
Enzyme Activity (Pressure)
Students will use a pressure sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
