Curated OER
Molecular Sequences & Primate Evolution: Amino Acids, Hemoglobins in Evolution
Students compare differences in amino acids in the beta hemoglobin from representative primates, complete a matrix of those differences, and from these data, construct and interpret cladograms as they reflect relationships and timing of...

Molecular Evidence for Evolutionary Relationships
Students compare the amino acid sequences in cytochrome-c for a variety of organisms and use this information to infer evolutionary relationships. Students investigate the role of homeobox genes and what this indicates about the...

Sequencing
Learners gather information about gene sequencing. In this biology lesson, students use the Internet to access information about gene sequencing, then work in pairs to read and record a gene sequence. Lesson includes extension activities.

Investigating the Soil
Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
