  • Why Does Biology Corner Have Advertisements?

    Why Does Biology Corner Have Advertisements?

    When I started this website in 2001, it was a simple project required to earn my graduate degree in educational technology.  At the time, all of the pages were created by writing html into a text file.  It was a painstakingly long process and the pages never really looked like I wanted them to.  Eventually,…

  • Bone Matrix Anatomy (Coloring)

    Bone Matrix Anatomy (Coloring)

    Anatomy students learn about the skeletal system, where they examine bones and how the bones fit together to make up an entire skeleton.   In addition, some course also explore bone tissue and how bone is formed, repaired, and even broken down to release minerals.   The bone matrix is composed of cells called osteocytes…

  • Analyzing Graphics:  The Carbon Cycle

    Analyzing Graphics: The Carbon Cycle

    This graphic illustrates how atmospheric carbon dioxide is produced during cellular respiration and combustion and then taken up by plants.   Students apply what they have learned about the processes of photosynthesis and respiration to label parts of the graphic an answer questions.  This activity is probably best done as a pair-share activity or a…

  • How to Use a Spreadsheet to Create a Graph

    How to Use a Spreadsheet to Create a Graph

    High school teachers often assume that their students know how to use basic word processing programs, internet browsers, and spreadsheets.  My students come to me with very little knowledge in how to do advanced tasks in those platforms, like inserting a graph or image.   I created this assignment to give students an introduction into…

  • Manipulate DNA in a Simulation to Explore Mutations

    Manipulate DNA in a Simulation to Explore Mutations

    This activity uses a simulation from the Concord Consortium. It shows how DNA is transcribed to RNA and then turned into a protein.  It’s a very clear animation and can be used on its own as part of a lecture on protein synthesis. I have even used this as a demonstration to show protein folding…

  • Scientific Method in Action

    Scientific Method in Action

    This simple worksheet has two reading passages, similar to what students may see on state standardized science tests.  Students read a short description of a science experiment and must answer questions related to science methodology, such as identifying controls and variables and summarizing conclusions that can be drawn from the text. The two stories are…

  • 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…

  • 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…

  • 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…

  • Inquiry in Genetics Using Wisconsin Fast Plants

    Inquiry in Genetics Using Wisconsin Fast Plants

    Genetic Experiments can be intimidating for teachers due to the time and cost of breeding plants or animals in a classroom.  These issues are further complicated in a public school setting which may have space issues, limited funds, and lack of access to labs.   My favorite model for genetic experiments is the Wisconsin Fast…

  • Meiosis Case:  SRY not SRY

    Meiosis Case: SRY not SRY

    Students are given a scenario about a female athlete who was stripped of her medal when it was discovered that her cells contain a Y chromosome.

  • Case Study – What’s Wrong with Timothy?

    Case Study – What’s Wrong with Timothy?

    The endocrine system can be a difficult subject to cover in anatomy.  It isn’t as showy as the other systems where you can label organs or dissect an eyeball.  Students must also memorize a number of hormones and their functions which have complicated names like thyroxine and tri-iodothyronine.   When I first started teaching anatomy,…

  • Case Study – Lice and Human Evolution

    Case Study – Lice and Human Evolution

    Google slides present a case of human evolution and the evolution of body lice. Students read details and data and answer questions in small groups.

  • Mitosis Coloring

    Mitosis Coloring

    Students read about each of the phases of the cell cycle and label and color a diagram that shows details of  interphase, prophase, metaphase, anaphase, and telophase.    Students must also label cell structures like the centrioles, aster, spindle, and nuclear membrane. This worksheet can be used as reinforcement for a lesson on mitosis and…

  • The Blue Bottle Demonstration

    The Blue Bottle Demonstration

    Most biology teachers must eventually accept the awful truth that they will need to include chemistry in their biology classes.  For years, the only chemistry I had to worry about was the very simple photosynthesis equation which was fairly easy to explain and also presented in an “unbalanced” form.   When I started teaching AP…
