Quantifying Marine Microbes: A Simulation to Introduce Random Sampling

Colored beads in a bag are used to represent different types of microbes, with the bag itself representing the ocean. Working in groups, each learner randomly samples ten “microbes” from the “ocean,” and records the data. To learn about the inherent variability of random sampling, the learner then compares the composition of their individual samples, their group’s pooled sample data, and that of the entire population. Introduce this lesson by reading and talking about the diversity of marine microbes.
