Anatomy of the Eye (Coloring)
The coloring worksheet is intended to help students learn the location of specific parts of the eye, like the cornea, sclera, lens, and retina.
-
Pedigrees – Human Genetic Disorders
Students practice identifying genotypes on pedigree charts. Focus on human genetic diseases, such as albinism, dwarfism, tay-sachs, and sickle cell anemia.

Genetics Practice Problems – Easy Mode
This worksheet was created for an introductory level biology class. This worksheet is designed to move through difficulty levels, so students start with “easy mode,” then moving to “normal” and then finally “hard mode.” Students can move at their own pace, which instructors can help students who are struggling.
-
Cellular Respiration Graphic Organizer
Students complete a graphic organizer that shows the process of cellular respiration.
-
Reinforcement: Cell Division
This worksheet was created for an introductory biology class because they struggled with the difficult vocabulary associated with mitosis and the cell cycle.
-
Cells Alive Worksheet
This worksheet follows diagrams and activities at CellsAlive.com which focuses on the size of cells compared to other objects, such as viruses and pollen. Students view interactive plant, animal, and bacteria cells to learn about the different structures associated with each.

Cell Labeling: Simple and Complex
Students practice labeling organelles on a simple model (2D) and a more complex model. The idea is for students to gain an appreciation for how cell diagrams are created. They don’t all look alike, and are often artistically created. Cell organelles tend to follow basic design rules, like the mitochondria will generally look like a…

Cell Cycle Labeling
Students label the image of a cell undergoing mitosis and answer questions about the cell cycle.

Data Analysis and Interpreting Graphs
Students practice analyzing pie charts, scatter plots, and bar graphs in the basic worksheet that is designed to pair with lessons on the scientific method. Most beginning biology students (in high school) are fairly adept at interpreting basic information from graphs, though scatter plots are sometimes challenging for them. I usually do this type…

DNA, Proteins, and Sickle Cell
In this activity, students use a codon chart to compare the DNA sequence of HbA (normal hemoglobin) to HbS (sickle cell). The DNA differs in a single base, where the codon for normal hemoglobin codes for glutamine, and the mutant form codes for valine.

Genetic Crosses with 2 Traits with Rabbits
Beginning biology students can struggle with dihybrid crosses and setting up Punnett squares that have two traits. When tackling this concept, make sure students are familiar and competent with basic genetic crosses and setting up Punnett squares for a single trait. For example, a tall (Tt) plant is crossed with a short plant (tt). Once…

Dragon Genetics
Add a little fantasy to your genetics unit by having students practice doing genetic crosses using dragons as specimens. Dragon traits include fire breathing, wingless, and color. I have students practice on whiteboards as we work through the slides and then I have students share their solutions with the class. The level 2 questions include…

Practice Problems: Genetics and Blood Types
This worksheet provides students with practice problems on multiple allele traits, specifically on how blood types are inherited. The problems focus on the ABO blood groups and students are asked to perform crosses where parents’ blood types are known. For example, if one parent has type O blood and the other parent has…
-
Practice Genetics: Sex Linked Genes
Students learn basic Mendelian genetics by crossing traits from fruit flies and pea plants. In this extension, students can practice doing crosses that involve sex-linked traits, where the alleles are located on the X chromosome which affects the pattern of inheritance. This worksheet is designed for beginning biology students, as it provides in most…

Simple Mendelian Genetics Practice Problems
Students learning basic Mendelian genetics can practice assigning genotypes and identifying heterozygous and homozygous configurations. Squares are set up to do crosses with purple and white flowers as seen in Mendel’s pea plants. The worksheet is very simple, designed for beginning students of biology and genetics. More difficult versions of genetics practice problems might…
