Investigation: What Factors Affect the Heart Rate of Daphnia
This investigation starts with a guided procedure where students gather data on the heart rate of daphnia when the organism is exposed to 1% ethanol. Daphnia are tiny crustaceans that are visible with the naked eye, though a microscope or stereoscope will be needed to see their heart rate.

Teaching Evolution Using Animal Models
Most evolution units start with a history of evolutionary thought, where scientists of the past, like Darwin, Linnaeus, Larmarke, and Wallace, are discussed with regard to their contributions to evolutionary theory. If you’re not careful, you can end up spending too much time on the history, talking about the Voyage of the Beagle and the…

Evolution & Taxonomy
Evolution is often called the “unifying theory of biology” because it organizes all of the observations gathered by biologists and proposes and explanation for those observations. All state standards for teaching science include a section on evolution (sometimes called adaptation or change over time). Related Page: Animal Groups – Organized by Phyla Evolution Evolution: Fact,…
