Measuring Biodiversity in Gorongosa
Take your biology class' understanding of biodiversity to a whole new level! Ecology scholars use data to calculate three different diversity indices based on the organisms in the Gorongosa National Park. The four-part activity uses an...

Around the World with DNA
DNA analysis could be what saves some animals from extinction. An interactive lesson shows learners how DNA information proves variation among animals of the same species and how stakeholders use that information to make decisions. Easy...

All About Horses
Horses come in all shapes and sizes, but all belong to the same species. Young scholars explore the different traits and connect the information to genetic modification. The interactive gives them the option to read about 18 different...

What Little Herc Saw
See the underwater world through a different pair of eyes! Middle school marine biologists identify deep-sea organisms by examining images taken by an ROV from the Okeanos Explorer. After determining what creatures lie beneath the...

Sampling Variation in a Natural Population
Learners examine the phenotypic variation within a natural population of a single species. They collect data on the species and analyze the data using statistical/spreadsheet software. Students interpret their results and present their...

The Physiological Tolerance of Two Species of Protozoans
Students examine the differences in pH tolerance between the two species and relate these differences to their respective niches.

Natural Selection and the Evolution of Darwin's Finches
Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

Owl Family Natural Selection
How do genetic mutations within a population lead to future variations? Provide your class with the resources to answer this question and more upon completing an activity on natural selection. The entire class participates in a fun role...

Natural and Artificial Selection
Many people oppose genetically modified foods yet support selective breeding in dogs. Learn about the similarities and differences through a short presentation that features many video clips. It covers natural selection, artificial...

Variations
Sttudents examine populations of living things and identify variations in physical features.

Natural Selection: Exploring the 'Ohi'a Common Garden
Seventh graders examine natural variation by visiting the Ohi'a Common Garden in Volcano, Hawaii. In this natural selection lesson, 7th graders study background information about phenotypes, genotypes, and phenotypic plasticity before...
Curated OER
Charting Diversity
Young scholars organize different species of plans and animals according to various characteristics. Students then determine what characteristics enable them to survive in their habitat. Game ideas and activities are included.

Leaf Stomata as Bioindicators of Environmental Change
Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Carousel Brainstorm
A variation of the Walkabout Review process, carousel brainstorming directs groups to rotate through a series of stations posting ideas on the topic or question posted at each stop.
Curated OER
How Unique Are You?
Students explore how genetic information is passed down from parent to offspring. Because of this, they examine how this causes the variation in each species.
Curated OER
Comparison of Evolution Mechanism
In this comparison of evolution worksheets, learners read information about Lamarck's hypothesis of evolution and Darwin's hypothesis of evolution. Students then rate the scenarios given as either supportive of Lamarck's or Darwin's...

The Great Jellybean Hunt
Students explore natural selection and its influence on the populations to fine tune traits and characteristics. The acquisition of traits developed out of need is examined through a game played in class.

Survival of the Fittest -- Battling Beetles
Learners experiment with traits. In this Science instructional activity, students test the strength of beetles using M&M candies in lieu of the insects. Learners use the Hardy-Weinberg Equation to calculate possible offspring traits...
Curated OER
The Birds and the Beaks
Learners explore the adaptations that birds have. In this adaptations lesson students view a video and create a concept map of birds and their adaptive traits.
Curated OER
Variation in Human Skin Color
Students classify themselves according to the six skin types. In this biology lesson, students explore the causes of human skin variation. They present their findings in class.
Curated OER
Birds, Fractions and Percentages
Students study fractions, percentages, spreadsheets, and computers by watching and recording the number of species of birdsseen. They create a spreadsheet to record the results of their one month study.

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...

Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

Asexual and Sexual Reproduction
Can you name a type of reproduction that produces no variation in the offspring? The multimedia lesson covers both sexual and asexual reproduction through videos and discussions. It includes topics such as genetic modification, meiosis,...
