How many plastic spiders are hiding in simulated “leaf litter”? Use the mark-recapture population sampling technique to estimate the number of organisms in a population. Capture, mark and release a random sample of spider in your "leaf litter". Recapture a second random sample of spiders and use a mathematical equation to estimate the total number of animals in the population. This complete "dry lab" activity contains all required materials.
