Modeling Meiosis and Independent Assorting Using Slides
Meiosis is a difficult topic for beginning biology students. There’s a lot going on in the cell to ensure that each new gamete receives half the DNA of the parent cell. In addition, each new cell is completely unique. This is the result of independent assortment and crossing over. Lessons on meiosis generally involve labeling…

Medical Errors – Don’t Use Pure Water Intravenously
I created this mini case study from a story about a patient given sterile water instead of saline in an intravenous drip solution. Students should probably have a learned about tonicity (hypertonic, hypotonic, and isotonic) before attempting this activity. The worksheet describes a scenario where a patient was hyperglycemic and the doctor ordered water be…

Label Digestive System
This worksheet was designed for anatomy students to practice labeling the organs of the digestive system. It is a little more advanced than what is typically seen in health or basic biology classes because it includes the three sections of the small intestine (duodenum, jejunum, ileum) and the three sections of the colon. (Note: I…

Jim Allison: Breakthrough
The film, “Jim Allison: Breakthrough” can be streamed through online platforms, like PBS or from Amazon Prime Video. Teachers can sign up for a free license at https://www.breakthroughdoc.com/for-educators The film is 1 1/2 hours long, which is longer than most class periods, and many teen attention spans, so I split the worksheet into two halves.…

Population Genetics in a Fishbowl
Students learn about Hardy-Weinberg equilibrium by exploring a virtual population of koi fish. This virtual lab allows students to run experiments where they can change variables, like population size, migration rate, mutation rate, and fitness of two separate alleles. The alleles being studied control the coloration of the fish. Fish can either be white, gold,…

Understanding the Evolution of Limbs in Snakes
Where did snakes come from? There’s a popular story about snakes in Ireland and how they were lead away by St. Patrick. From a science perspective, snakes likely never were in Ireland to begin with. Many islands don’t have snakes. Why? Because they haven’t had time to evolve there. The activity is adapted from Understanding…

How Can Changes in a Population Lead to New Species?
This lesson explores the two models of speciation: allopatric and sympatric. You can also assign a simple print version that explores speciation modes. Students first read about allopatric speciation and apply it to the finches on the Galapagos islands. Each finch species became isolated on its own island, which resulted in each island having a…
