How Many Critters Live Here? Estimating Wildlife Populations.

A quick discussion question that brings some collaboration into your classroom will allow your thinkers to make a decision about sampling. Mr. Briggs wants to know if the results from his class are a valuable comparison to the entire...

When more basketball players are taller than field hockey players at a school, is it safe to say that in general they are always taller? The activity takes data from two college teams and your learners will be able to answer questions...

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...

When you are trying to learn a particular characteristic of a large population, you need to be able to study an unbiased sample of that population to be able to draw accurate conclusions. Watch this video for an in-depth explanation. [5:04]

Have you ever wanted to take a short cut? How about when doing your math homework? In this experiment you can learn how estimation can save you time doing math calculations. But beware, some estimations are better than others. Can you...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Be stupefied by stratified sampling. Viewers of a short YouTube video learn about stratified sampling. Given information on the number of people majoring in a particular subject, they decide how many of each major they need to create a...

Students create a WANTED poster about an invasive species to an ecosystem. In this invasive species lesson plan, students watch a video and research an invasive species and create the WANTED poster about it.

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...

Students experiment with pea pods to observe/appreciate the diversity of individuals within a population, and to explain of how dominant and recessive traits, genotypes, and phenotypes help produce variation in a population.
