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…

Investigation: Sticklebacks
This investigation was modified from the HHMI Stickleback Modeling activity where students examine two different forms of the the stickleback fish. One form has spines and bony armor and is found in the ocean. The other has less armor and is missing its pelvic girdle, and is found in fresh water lakes. The activity has…

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…

Amylase Enzyme and Copy Number Variant
This activity explores a data set on the frequency of copy number variants in the gene AMY1 that codes for amylase activity in the saliva. Amylase is an enzyme that breaks down starch into sugar. The activity builds on the HHMI data point showing how presence of multiple copies of the gene correlate to populations…

Muscles Labeling
This activity is aligned to my anatomy and physiology curriculum where students study the structure and function of muscle tissues. This has been a challenging topic to cover remotely because I can’t use traditional models. Typically, I would use straws and rubber bands to model fascicles and myofibrils. This activity is part of a unit…

Photosynthesis Virtual Lab
This lab was created to replace the popular waterweed simulator which no longer functions because it is flash-based. In this virtual photosynthesis lab, students can manipulate the light intensity, light color, and distance from the light source. A plant is shown in a beaker and test tube which bubbles to indicate the rate of photosynthesis.…
