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…

Storylab: Diffusion
This story is written from the perspective of a student who in experiencing the real lab. It describes how the lab is set up, by placing a bag filled with starch in a beaker full of iodine. The teacher in the story explains relevant terms, such as semipermeable, diffusion, and indicators.

Genetics: Sexy Chickens
This worksheet was designed for advanced students of biology or for honors students who are ready for an extra challenge. Birds have a ZW sex determination system instead of the XY system seen in humans. If your students have a good grasp on sex-linked traits in humans, then this scenario is a way to really…

Simple Diagram Labeling on the Parts of a Chromosome
A diagram of a chromosome in the nucleus of the cell. Students label the chromatid, centromere, chromosomes, cell membrane, DNA, and nucleus.

What is a Cladogram?
Students are given a description and an example of a cladogram showing the relationship between lizards, snakes, crocodiles, and birds. They are then walked through the process of creating a cladogram for five animal examples: frog, fish, bird, koala, and lizard. The process involves suggesting traits that these animals share and finding traits that are…

Label and Color the Urinary System
This simple worksheet asks students to label the major structures of the urinary system. They can also choose to color the diagram. I use coloring sheets in anatomy and physiology classes but this could also be used in biology or as a supplemental graphic for a frog or fetal pig dissection. Though many of my…

Devils, Chromosomes and Cancer
This is a good follow-up activity to the Tasmanian Devil Karyotype, where students examine how the chromosomes of cancerous cells can be altered. It is a short read about a transmissible cancer found in Tasmanian devils which causes facial tumors. This cancer, known as is has already killed 85% of the overall population and threatens…

Label and Color the Kidney
This worksheet has a very simplified view of a kidney showing the cortex, renal pyramids, renal artery and vein, renal pelvis, and ureter. Students can practice labeling the structures and color coding the diagram. This worksheet was designed for a high school anatomy and physiology class and complements two other labeling and coloring worksheets: urinary…

Hardy Weinberg Problemset
Hardy-Weinberg equilibrium (HWE) is a fundamental concept in population genetics that describes the theoretical relationship between allele frequencies and genotype frequencies in an ideal, non-evolving population. Students can practice using the Hardy Weinberg equilibrium equation to determine the allele frequencies in a population. This set of 10 questions gives students just enough information to solve…

Reinforcement: Evolution
This worksheet was designed for an introductory biology class where students are exposed to basic concepts of biology. The unit covers the history of evolutionary thought (Darwin and the finches of the Galapagos) I focus more on modern examples of evolution, such as rock pocket mice and giraffes. Students match a description or definition to…

Complete Cat Dissection Student Guide
Cat dissection manual for anatomy and physiology students. A cat dissection is not usually performed in biology and reserved for upper level anatomy or college students. My anatomy class is only available for juniors and seniors. Some students may have ethical issues with dissections, and I refer them to an alternate version for the dissection…

Reinforcement: DNA
This worksheet was designed for 2nd year biology (AP Biology) as a way for students to review the structure of DNA and the history of the experiments that lead to its establishment as the molecule of heredity. Historical references include those related to Frederick Griffith’s experiments with transformation in bacteria and Hershey-Chase experiments with bacteriophages.…

Digestive Concept Map
Students use this concept map to reinforce their understanding of the digestive system and how structures within that system are related. The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down food. The esophagus is a muscular tube that connects the mouth to the stomach. The…
