Random Sampling
In this random sampling worksheet, students compare data collected by a random sample to data collected by an actual count using pieces of paper with numbers written on them. They compare their data for the actual count to the random...

Mark, Recapture, Sampling
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...

Galaxy Hunter - A Cosmic Photo Safari
Space science stars journey through our night sky and take virtual photos of galaxies to investigate simple random samples. Higher math is used to analyze the data collected. Copy the evaluation/assessment questions onto a handout for...
Biology Corner
Random Sampling
Simulate a random sampling of data by tearing 20 sheets of paper into slips and place a number on 10 and a letter on 10. They place the slips in two separate containers and randomly draw a number and a letter. They record their...

Population Genetics
Genetic variation shows the health of a population, yet cheetahs show very little variation over that last 10,000 years. Scholars learn the importance of genetic variation in populations after viewing an informative presentation. It...

Random Samples: Estimating Population
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...
Curated OER
Surveys and Samples
For this surveys and samples worksheet, students discover data collection techniques and write their own survey questions. Students use random sampling, convenience sampling, and systemic sampling and analyze their results.

Hypothesis Testing: Two Sample Tests
Young scholars experiment and compare results of two populations. In this men and women populations lesson, students examine the difference in hand span for men and women. Young scholars calculate a norm based on their results. Students...

Sustaining Our Ocean Resources
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 fish populations are...

Annual Wetland Plant Diversity Survey
High schoolers locate an area of marsh and, by measuring the total number of individual plants in a sample area, determine whether purple loosestrife population density is correlated to the total plant diversity of the community. They...

From Restriction Maps to Cladograms
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....

Got Lactase? The Co-Evolution of Genes and Culture
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...

Activity 3: Using Photo Images to Explore Life on the Ocean Floor
Students work in groups with copies of the three photo images provided with the lesson. They make observations about mussels and clams. Students discuss reasons scientists use a representative sample of a population rather than the...
Curated OER
Catch, Tag, and Release
Learners discover how fish tagging is used by marine biologists and fisheries to estimate fish populations. Participating in a simulation, students use estimation to determine the whole population from a small number of items.

Questioning NASA
Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

Biodiversity in Your Backyard!
Take your enthusiastic ecologists outdoors to explore the biodiversity right in their own schoolyard! In preparing for this activity, it may be worthwhile to research websites with local flora to help in the plant identification portion.

Mussel Ecology
Students are introduced to the marine environment of the mussel. The emphasis of the instructional activity is upon what human factors are present to influence the environment in positive and negative ways. They brainstorm in groups in...

Brays Bayou Spiderwort Genetic Study
Students formulate hypothesis based upon data gathered by examining possible crosses of spiderworts using Punnett squares. They present explanations for physiological adaptations of spiderworts that resulted from interactions within the...
Curated OER
CATCH, TAG and RELEASE
Students apply estimation strategies for problem-solving purposes. They become familiar with one aspect of a marine biologist's work.
Curated OER
From Restriction Maps to Cladograms
Pupils develop a matrix to determine the number of differences between each set of primate species. They determine closely related organisms then complete the cladogram and answer a set of questions.
Curated OER
Insect Classification
Pupils compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
