2013 AP® Biology Free-Response Questions
AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

Beaks as Tools: Selective Advantage in Changing Environments
How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

Evolution in Action: Data Analysis
An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

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...

Island Rotation: Lesson Plan 4
Foster's Rule? Allopatric speciation? After watching West of the West's documentary Island Rotation, class members use Venn diagrams to compare endemic species on the Channel Islands with mainland related species. They then create a...

Chapter 23 Guided Notes: The Origin of Species
This doesn't have to be used as a guided notes instructional activity because the questions are thought-provoking and applicable to any biology class that is learning about the origin of species. Pupils write out answers to questions...

AP: Chapter 24: The Origin of Species
AP biology buffs define vocabulary terms and answer critical-thinking questions about evolutionary trends. They compare macroevolution to microevolution, differentiate ploidy possibilities, explain isolation barriers, and more....

Speciation and Genetic Drift Worksheet
Fifteen terms pertaining to speciation, extinction, and gene flow are to be matched to their definitions. This simple, easy-to-read activity can be used as a pop quiz for your biology learners when studying natural selection principles...

Origin of The Species
After viewing information about different types of isolation, students will see that reproduction among a group will cause the frequency of a specific trait to increase. The history of prominent scientists such as Charles Darwin are and...

Survivors on the Ocean Ridge
High schoolers discover the uniqueness of deep sea hydrothermal vent organisms through an exploration of the NOAA Galapagos Rift Expedition. They study the genetics and evolution of a shrimp species that lives near the vents then they...

A STEP IN SPECIATION
Students place different subspecies of a CA salamander are placed on grid map of CA according to where samples were collected. Then discuss patterns of their distribution, their likely evolutionary relationships, and probable sequence of...

The Process of Speciation
Students illustrate the results of natural selection by identifying conditions that could lead to the development of new species (speciation) based on a given description of environmental conditions and description of variation within a...

How Do New Species Form?
Students read an article by Niles Eldridge about species and the environment and break into small groups to discuss it. They write essays noting strengths and weaknesses of punctuated equilibrium and gradualism, or other topics listed.

Island Biogeography and Evolution
Learners develop likely phylogenies for seven related populations of lizards living on the Canary Islands using real data. They organize charts, and record the data for geography, geology, morphology, and molecular genetics.

Anolis Lizards of the Greater Antilles
Students "take a trip" to the Greater Antilles to observethe Anolis lizards. They study the body structures and habitat of different species, then plot this data on a map to look for patterns in their distribution. From the patterns they...
