Curated OER
Why do we need Vitamin C in our diet? Or Why do we carry old inactive genes in our genome?
Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...
Curated OER
What came first?
Students sequence events in their own lives and assign each a numerical time, students use the same process to sequence actual events in the evolution of life on Earth.

Taxonomy: Who is in My family?
Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...

Historical Climate Cycles
Ice core samples give scientists access to climates of old—those from more than 800,000 years ago. Through an analysis of various temperature graphs from ice cores, tree rings, and weather stations, scholars compare historical climates...
Curated OER
Species Diversity and Phylogeny
Students explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.
Curated OER
Niches and Adaptations
Young scholars present information about a species, its niche, and adaptations. In this lesson on animal environments, students explore how surroundings can affect a given population resulting in adaptation.
Curated OER
Birds
Students study birds and examine the idea that they evolved from reptiles or dinosaurs. In this birds lesson students divide into groups and research one side of the debate, then at the end have the students debate each-other.
Curated OER
Half Life Lab
Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
Curated OER
Chromosome Fusion
Students see how patterns can reveal events of the past, thereby merging elements of both experimental and historical science.
Curated OER
Biology: Natural Selection
Students explore evolutionary processes and theories using the spotted fish applet. They observe what happens to fish in a closed environment with both food and predators. Students run the model several times and answer questions about...
