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...

Students explain the significance of population trends on world regions. They define relevant population vocabulary and examine age-gender patterns at various scales.

With this estimating populations assignment, your class will learn about taking random population samples and calculating the average number of species in the samples to estimate the total population. Students use the given data to find...

Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.

Young mathematicians define population, draw convenience sample from the population, draw quota sample from the population, and draw random probability sample from the population. They explain why a random probability sample usually...

Ninth graders discover how statistics are used to interpret results of scientific experiments. Students write hypotheses and test the hypotheses by collecting data and organizing the data. Students graph their data to produce a visual....

Students learn how to count animal populations by the Mark and Recapture method. In this counting animal populations lesson plan, students begin by predicting amounts of different candies in a jar. Students then simulate using beans, two...

In this sampling methods worksheet, students solve the six problems using sampling methods and determining if the results are biased or unbiased.

Students identify and describe major geographical features of the Middle East and explain how these features and other natural resources influence the economy of the area. Then they research one of the middle-eastern countries listed,...

Students test the factors that influence the rate at which a virus spreads through a population. They complete a lab activity then discuss data collected and review and answer a set of questions.

Lead young scientists on an investigation of fishery practices with the final installment of this four-part unit. Using a PowerPoint presentation and hands-on simulation, this lesson engages children in learning how...

Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

Eleventh graders practice the Quadrat Survey Technique to analyze the biodiversity of a local plant community. They compare its biodiversity with the documented changes in biodiversity of the tallgrass prairie over time.

Students use different sampling methods to determine the population size and appropriate space for monarch butterflies. In this averages lesson plan, students complete word problems where they can accurately estimate the size of an...

Biology aces analyze restriction maps to determine the relationships among different primate species and then complete a cladogram. Preface this lesson with an explanation of how restriction enzymes are used to create the DNA maps....

Students explore the population of grass plants in a given area. They plan and conduct a sampling activity to estimate the population of dandelions or the number of grass blades on the school grounds.

Seventh graders discuss water issues and its affect on salmon population. They recreate a sampling river with fish (cheddar) and scoop them to tag them (which means they exchange them for pretzel fish.) They complete a spreadsheet to...

A math and science worksheet prompts learners to simulate how scientists determine populations of animals out in the wild. They use goldfish crackers, paper bags, and a styrofoam cup as their tools. An excellent cooperative group activity!

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Grateful learners put turkey on a table (or a graph)! Through a creative project they show statistical information about turkey population, production, and consumption. A great Thanksgiving lesson that can be applied at any time to the...

Students define sample, describe a random sample, and discuss what compromises a sample. They determine a sample size to estimate a population characteristic with confidence.

Students explore the concept of a quadrat study. Students select and investigate a site and conduct a quadrat survey. They take measurements, observe the area and analyze their findings.

What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.
