Capture-Mark-Release-Recapture Experiment

This video tutorial guides viewers through a virtual experiment on the capture-mark-release-recapture technique, part of the Biology Form 5 KSSN curriculum. It covers setting up the experiment on virtualbiology.org, adjusting settings, conducting the experiment, and analyzing data to estimate population size. The tutorial emphasizes understanding the process and assumptions involved in the experiment.

What is the main focus of the virtual experiment discussed in the video?

• Cell division

• Genetic mutation

• Capture-mark-release-recapture technique

• Photosynthesis process

Which website is used to conduct the virtual experiment?

• virtualbiology.org

• biologyexperiments.com

• biologysimulation.org

• virtualscience.net

What should the population size be set to for the experiment?

• Small

• Medium

• Large

• Extra Large

How many traps are recommended for use in the experiment?

• Six or ten

• One or two

• Two or three

• Four or eight

What is the purpose of marking the animals in the experiment?

• To measure their size

• To identify their species

• To track their movement

• To distinguish them from unmarked animals

What assumption is made about marked and unmarked animals after release?

• They remain in separate groups

• They mix randomly in the population

• Unmarked animals avoid traps

• Marked animals dominate the habitat

How long is each capture session in the experiment?

• 8 hours

• 10 hours

• 4 hours

• 6 hours

What is the formula used to estimate the population size?

• (First capture + Second capture) / Marked in second capture

• (First capture / Second capture) + Marked in second capture

• (First capture x Second capture) / Marked in second capture

• (First capture - Second capture) x Marked in second capture

What is the estimated population size calculated in the experiment?

• 64.2

• 98.3

• 120.5

• 150.7

What is the benefit of using virtual experiments like the one in the video?

• They are more expensive

• They provide hands-on experience

• They allow for better understanding of concepts

• They require less time to complete
