Curated OER
Diversity/Natural Selection
Learners examine mechanisms behind biological evolution and the theories that feed it, and are able to demonstrate their knowledge of these theories in a story.

Natural Selection and Evidence Worksheet
Matching and fill-in-the-blank exercises give biology whizzes a chance to practice vocabulary associated with evolution. Terms to be reviewed focus on evidence for evolution, natural selection concepts, and some genetics words. You could...

Thanksgiving: Bird Evolution
Students explore the evolution of birds. For this biology lesson, students research articles that discuss evidence about the ancestry of birds. They discuss their findings with the group and draw a journal magazine cover highlighting...
Curated OER
Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...
Curated OER
Comparative Embryology
Students compare and contrast the embryonic development of human, chicken and fish embryos. They create a detailed outline of similarities and differences among the three embryos at various stages of development.
Curated OER
A Tree of Life Activity
Students solve a mystery of the identification of a unknown organism by comparing its morphological characteristics to those in a tree of life classification poster. They compare the observable characteristics of the specimen and...

Plant Diversity
Ginkgo trees existed for more than 350 million years, and, at this time, only one species still remains. While plant diversity generally increases over geologic time, some interesting exceptions occur. Young scientists learn about plant...
Curated OER
History Theory of Evolution
Students identify fossils. They identify evidence of change over time when given pictures of fossils to determine the proper sequencing. In addition, they determine evolutionary relationships by comparing embryonic structures.
Curated OER
Darwin's Theory
Students write an essay about evolution. They summarize Darwin's Theory and discuss its strength and weakness of evolutionary theory. Students discuss the struggle of existence and survival of the fittest. They discuss the evidence of...

Comparative Embryology Using Japanese Medaka Fish
Young scholars conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
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.

Basic Genetics
Ninth graders discover where their physical appearance and personality traits come from. In this genetics lesson, 9th graders learn about cells, chromosomes, DNA and genes. Students discover where genes come from as well as dominant and...
