Case Study – The Placenta, MS, and a Viral Past
What if we told your students that a gene critical to human pregnancy came from a virus? And what if that same gene, when turned on in the wrong place, might play a role in multiple sclerosis? This is the real and fascinating story behind Syncytin-1, a protein that reveals just how tangled the relationship…

Murder Mystery Macromolecule Lab
If you’re looking for a creative and engaging way to teach biological macromolecules, look no further than this murder mystery lab activity. Students become forensic scientists, analyzing evidence to solve a crime. Using Lugol’s iodine, Biuret solution, Benedict’s solution, and Sudan IV, students will identify macromolecules in the contents of a victim’s stomach and match…

Macromolecules Lab – Testing for Starch
Most biology textbooks have a chapter on macromolecules. In chapter 2 of our textbook, students learn about the chemistry of life, which includes the basics of atoms and molecules, properties of water, and carbon compounds. I generally include a food testing lab where students determine the macromolecules found in food. The lesson is engaging, informative,…

Case Study: Cystic Fibrosis Mutations
This case study is a follow-up to the Cystic Fibrosis Case Study where students explore how changes in transport proteins affects the movement of ions, resulting in a build-up of chloride ions and the symptoms of the disease. Students were introduced to the idea that different mutations can cause differences in the transport proteins, but…

Genetics of Sickle Cell
This assignment was created for students who miss class and can be completed independently. There are sections to read with questions to answer, focusing on how DNA provides the instructions to make protein. A single base substitution in the gene that codes for hemoglobin results in sickle cell anemia. Students are walked through the process…
