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…

Investigation – Animal Behavior with Isopods
An isopod is a crustacean with a segmented body and seven pairs of legs. They are commonly known as pill bugs, roly-polys, or woodlice. Isopods are found in a variety of habitats, including soil, under rocks, and in decaying wood. They are detritivores, meaning they eat dead and decaying matter. Isopods are an important part…

Food Web: Identify Consumers
Food webs are basic concepts in biology and ecology, where students learn the concept of energy flow in an ecosystem by viewing models of food webs. This labeling worksheet asks students to identify the primary, secondary, and tertiary consumers in a forest ecosystem. A food web is a representation of the complex interrelationship between…

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…

The Anatomy of the Kidney and Nephron
This coloring worksheet asks students to color the kidney to identify where structures like the medulla, cortex, renal vessels and ureters are located. Another image focuses on an individual nephron to identify the glomerulus, proximal and distal tubules, and the Loop of Henle. This worksheet is intended for advanced students of anatomy. Students will…

Modeling Independent Assortment & Dihybrid Crosses
Students examine how two traits are inherited, revealing that each allele has an equal chance of being passed on to the next generation, the principle of independent assortment.

Compare a Human and Chimpanzee Skeleton
This handout can be used in discussions on the evolution of bipedalism or in any unit on the skeletal system. Students label the bones of the skeleton and make comparisons between the forelimbs, hind limbs, and pelvis. I created this handout to compliment an evolutionary lesson and video from HHMI on the “Origin of Humans”…

Investigation: Modeling Heredity with Popsicle Sticks
In this activity, you will use popsicle sticks to model the process of gamete formation and the combining of sperm and egg to create offspring. Results of the simulation can then be compared to Punnet square expected results. Popsicles should be made in advance, the set contains a male and female set with the genotypes…

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…

Investigation: What Factors Affect Lung Capacity
In this investigation, students use balloons and rulers to estimate the vital capacity of lungs using test subjects within the class. To perform the test, subjects take a deep breath and blow into a balloon. The diameter is measured and a graph is used to estimate the volume of air expelled based on the diameter…

Case Study: Why Are There No Male Calico Cats?
This presentation case study asks two important questions regarding cat coloration: The case is presented as a slide presentation where students consider evidence and data related to cat coloration and chromosomes. Working in small groups, they discuss the case and eventually answer the two main questions. I usually collect their answers at the end of class…
