Estimating Population Size – Remote Learning Unit
Population growth studies are a common element to studies in ecology in my basic biology class. Students learn about exponential and logistic growth the impacts populations have on the environment. As part of this unit, I have had students simulate techniques used to estimate the size of a populations. I have toys packed in bags…

Estimate a Person’s Height from the Bones
In this activity, students use tape measures to estimate the length of their femur, ulna, and tibia. These lengths are then with an equation to estimate their height which can then be prepared to their actual height.

Estimating Population Size: A Netlogo Simulation
Students learn how the “mark and recapture” technique can be used to estimate population sizes by using a netlogo simulation that allows students to alter variables such as population size, and number of individuals marked.

Random Sampling
Students model how field biologists would use a sampling technique to estimate the number of sunflowers in a field. First, they choose 10 plots at random by choosing paper slips, then take the average of those plots. The worksheet walks them through the steps of then using the average and the overall size of the…

Investigation: Estimating Population Size
In this investigation, students simulate how mark and recapture techniques are used to estimate population size. Prepare populations in advance by gathering 60-150 small objects, like toy spiders, beans, or beads. Toy animals seem to be more exciting for students, and you can sometimes find them at dollar stores. In my class, I…
