Acid Precipitation
Students test the acidity of unknown solutions. They use this information to make inferences from data given from recorded rainfall records to identify areas that receive the most acid rain.
Curated OER
Acid and Bases - Alien II
Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

Molecular Evidence for Evolutionary Relationships
Learners 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...
Curated OER
DNA Sequencing Simulation
Students simulate the Sanger method of DNA sequencing using color pop-beads as a representation of nucleotides and dideoxynucleotides. Students assemble DNA sequences and run their sequences through a "sequencing gel" and sketch what...
