Learners conduct a simulation to explore how scientists estimate the size of animal populations. They analyze a random sample and then extrapolate those results to a larger population. Additionally, they will apply the principals of...

Help learners discover methods to estimate animal population. They will participate in a simulation of catching and tagging fish in order to estimate the fish population. They scoop and count goldfish crackers, record data, and use...

Seventh graders use paper bags and crackers to simulate a wildlife sampling of salmon. They record data on spreadsheets and determine a formula to estimate salmon populations.

Students use their math skills to develop estimates for the population of several animal species native to the Austrailian rainforest. It is a simulation that researchers at the Center for Rainforest Studies in Australia perform to...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

How quickly do animals evolve? Can comparing different samples of the same fossil answer timeline questions? Scholars use virtual labs to examine fossils and learn about stickleback evolution. They compare pelvic morphology in lakes...

Students investigate marine life by researching aquatic organisms on the Internet. In this oceanography lesson, students monitor algae and animals of the ocean by identifying their population and habitat on data sheet ID cards. Students...
