Introduction to Adaptation
Tenth graders observe collections of specimens and discuss their answers to provided questions. They explore common ancestry, homology, analogy, adaptive radiation, and evolution, while formulating creative answers based on their...
Curated OER
The Evidence for Evolution
Summarize a unit on evolutionary evidence. Learners recount information about the fossil record, molecular record, homologous structures, convergent evolution. This learning exercise provides plenty of room for students to write out...
Curated OER
Homologous Shoes
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.

Understanding Evolution: Homology and Analogy
In this understanding evolution worksheet, 9th graders define homology and analogy. Students compare and contrast similar structures in several given species.
Curated OER
Evidence of Evolution by Natural Selection
Walk your junior biologists through the evidence that supports evolution. The fossil record, anatomical record, and molecular record are explained and supported by colorful graphs and pictures. Extensive notes are provided for some of...
Curated OER
Homology: Where Does The Evidence Lead
Students are introduced to the topic of homology. In groups, they read a case study and compare different drawings of early vertebrate emryos. They work together to answer discussion questions and label the various parts of each embryo.
Curated OER
Homology
Young scholars investigate the concept of homology. They are particularly interested in finding information about developmental homology. Students design a new animal correcting obvious mistakes on a worksheet provided by the teacher....

Dragon Genetics - Understanding Inheritance
Six pages begin with a detailed introduction to meiosis and homologous chromosome pairs. Instructions guide learners through a simulation in which they draw craft sticks marked with autosomes in order to decode the genes inherited by...
Curated OER
Evidence for Evolution
In this evidence of evolution worksheet, students review notes given by referring to the Nelson Biology text, chapter 11/13. Students read the notes and the specified pages in the text.

The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

How Eyes Evolved – Analyzing the Evidence
Octopodes existed for hundreds of thousands of years before humans, yet our eyes share many similarities. Scholars analyze the evidence to determine if the evolution of eyes best fits a homology or analogy model. They discuss the issue...
Curated OER
Evidence of Change
Students identify evidence of change in species using fossils, anatomical similarities, and embryology. They identify homologous structures and arrange the steps of fossil formation. Students complete a group of selection of organisms...
Curated OER
Meiosis
In this meiosis worksheet, student complete the blanks describing the process of meiosis. Students draw a diagram of homologous chromosomes.
Curated OER
Cell, Socks, and Sex
Donate old socks for science! Young biologists model mitosis and meiosis, using socks as chromosomes and a balloon as a nucleus. This ingenious idea for modeling cell division will be more memorable to your young biologists than any set...
