Lab: How Do Enzymes Work
Explore how enzymes work with this engaging lab. I redesigned this lab with freshman students in mind. The directions are simple. Students drop hydrogen peroxide onto raw liver, and observe the bubbling. The bubbles are oxygen as it is being released in the reaction. The lab handout includes a background section that explains how enzymes…

Data Analysis – Tool Use in Primates (CER)
Chimpanzees, capuchins, and long-tailed macaques use tools to crack the shells of nuts. They place the nut on a hard surface, like a flat rock, and strike it with a stone to crack the shell. These three primate species use different techniques. Chimpanzees and macaques crack the nuts while sitting, but the capuchin stands on…

Label the Digestive System of a Rabbit
Students in biology may or may not do extensive dissections, but most biology classes do include a unit on comparative anatomy. Many teachers substitute dissections with virtual labs or paper versions of dissections where students label, color, or cut out parts. This worksheet shows a simplified diagram of a human and a rabbit digestive system…

Bird Digestive System
This worksheet provides an image of a chicken focused on the digestive system as part of an overall unit on comparative anatomy. Students label the major organs of the system which are similar to the human and frog. The chicken does have some digestive system adaptations , such as a crop, proventriculus, and gizzard, which…

Frog Anatomy Label
This worksheet is a supplement to the frog dissection activity where students examine a preserved specimen. The main structures of the abdominal cavity are shown on this image and students practice identifying them using the included word bank. ( The worksheet could be modified to not include it should students need a greater challenge. )…

Label Steps of DNA Replication
For freshman, DNA replication is only covered in basic terms, where students are told that the process is semi-conservative and leads to the production of two new identical strands. AP Biology students are required to learn te steps of DNA replication and the roles that enzymes like DNA polymerase, helicase, and ligase, play in the…

Reinforcement: Scientific Processes
I designed this worksheet for an introductory biology class. It reinforces concepts that are introduced in the first chapter. Students learn about how science works, what a hypothesis is, and how data is analyzed. Reinforcement worksheets have definitions or sentences that include a key word and students much choose from a bank of vocabulary words…
