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…

Falling Cats – CER
Students practice Claim, Evidence, and Reasoning (CER) while examining the relationship between falling height and cat injuries. The graphs show that cats who fall 2-7 stories often suffer more injuries than cats who fall from greater distances. Not much information is given about how the data was collected, though the original source is included, I…

DataClassroom
High school biology classrooms often lack the time and resources to do long term studies and data collection that researchers engage in. Luckily for us, many projects make their data available for use by schools. Organizations like HHMI and Data Nuggets have created student resources that focus on analyzing real scientific data. One of these…

Experimental Design
Students in most science classes start with an overview of scientific processes. For advanced students, I use this cheat sheet to remind them of the major features of the scientific method, such as a control group, dependent and independent variables. AP Bio students are also introduced to the concept of the null and alternative hypotheses…
