  • Color a Typical Prokaryote Cell

    Color a Typical Prokaryote Cell

    This worksheet is similar to the animal cell coloring and the plant cell coloring, where the focus is on structures found in the cell and how those structures relate to the cell’s function. Students read a short passage about prokaryotes and the two kingdoms of bacteria: archaeabacteria and eubacteria.   The passage includes information about…

  • Case Study: How Do Genes Determine Skin Color?

    Case Study: How Do Genes Determine Skin Color?

    This case study focuses on a news story whose headline declares that a “mother is a the only black woman to give birth to two white babies.”    Students look past the sensationalized headline to discover how skin color is controlled by multiple genes and make a final judgement about whether statements made in the…

  • DNA Coloring

    DNA Coloring

    DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses. It consists of two long chains of nucleotides twisted into a double helix structure. Each nucleotide is composed of a sugar molecule (deoxyribose), a phosphate group, and…

  • What Is an Autopsy?

    What Is an Autopsy?

    A short article about autopsies and medical examiners intended for students in anatomy. Students read a detailed description of an autopsy and answer questions that require close reading

  • Practice Problems:  Genetics and Blood Types

    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…

  • Analyzing Human Pedigrees

    Analyzing Human Pedigrees

    Examine pedigrees to determine carriers in a family and inheritance patterns.

  • Investigation – Animal Behavior with Isopods

    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 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

    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…

  • Modeling Independent Assortment & Dihybrid Crosses

    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

    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

    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

    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

    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…

  • How to Learn the 12 Cranial Nerves

    How to Learn the 12 Cranial Nerves

    Learn the 12 cranial nerves with this simple mnemonic and coloring worksheet, appropriate for high school anatomy students.
