  • Sliding Filament Coloring

    Sliding Filament Coloring

    Step by step guide of the sliding filament model;, contraction starts with a nerve impulse and ends with muscle fibers shortening. Students color the diagram.

  • Label Steps of DNA Replication

    Label Steps of DNA Replication

    For freshman, DNA replication is only covered in basic terms, where students are told that the process is semi-conservative and leads to the production of two new identical strands. AP Biology students are required to learn te steps of DNA replication and the roles that enzymes like DNA polymerase, helicase, and ligase, play in the…

  • Evolution Crossword

    Evolution Crossword

    This simple worksheet is designed to help students with vocabulary and study for their test over the Theory of Evolution by Natural Selection.

  • Human Population Growth

    Human Population Growth

    Students graph population estimates for years ranging from 1650 to 2012. The graph will show an exponential growth curve which students analyze to determine how frequently the population doubles. Students also explore the concepts of carrying capacity and growth rates. Questions ask students to discuss what happens when the earth exceeds its carrying capacity and…

  • Cell Cycle Label

    Cell Cycle Label

    This worksheet was created for freshman level biology and is a simpler version of a worksheet I use in the advanced classes showing the cell cycle. The image shows a cell in interphase, prophase, metaphase, anaphase, and telophase. Students label each phase and then identify structures within the cell that are important for cell division,…

  • Exploring Enzymes by Analyzing Graphics

    Exploring Enzymes by Analyzing Graphics

    Students examine several images related to enzymes and answer questions. Worksheet covers how enzymes act on substrates, how they lower the activation energy of a reaction, how they have optimal temperature and pH, and how they can be inhibited.

  • Modeling Osmosis

    Modeling Osmosis

    This basic lab uses Deco-cubes to show how they change in size when soaked in salt water, distilled water, and tap water.

  • Reinforcement: Genetics

    Reinforcement: Genetics

    This exercise was created for an intro bio class though it would also be appropriate for other levels or students who struggle with basic vocabulary. The word list includes terms such as: phenotype, genotype, heterozygous, dominant, and recessive. Also included on the list are several genetic disorders like hemophilia and sickle cell. The worksheet was…

  • Anatomy and Physiology  Lesson on Tissues

    Anatomy and Physiology Lesson on Tissues

    Phenomenon based unit where students examine the case of a child with the epidermolysis bullosa.

  • Reinforcement: Cell

    Reinforcement: Cell

    This is a practice worksheet for students who are learning structures found in the cell. A list of terms can be matched with descriptions and definitions. The same terms can be used to label a diagram of an animal cell. I use reinforcement worksheets for review or remediation. I will give students 10 minutes to…

  • Falling Cats – CER

    Falling Cats – CER

    Students practice Claim, Evidence, and Reasoning (CER) while examining the relationship between falling height and cat injuries. The graphs show that cats who fall 2-7 stories often suffer more injuries than cats who fall from greater distances. Not much information is given about how the data was collected, though the original source is included, I…

  • Early Discoveries – CER

    Early Discoveries – CER

    Explore historical scientific discoveries, like Pasteur’s experiments to learn about the scientific method.

  • Investigation: Earthworm

    Investigation: Earthworm

    This earthworm lab is a revised version of the observation lab that I have used for years. I wanted to make the lab more open-ended and include terminology within the lab instead of expecting them to know it from their notes or textbooks. Taxonomy chapters on annelids and other invertebrates are being phased out, and…

  • The Martian and the Car

    The Martian and the Car

    This worksheet is one of the older ones in my collection, and was recently updated to include a Claim-Evidence-Reasoning section (instead of short response/essay). This a a great way to introduce the topic of life and how we define whether something is living or not. In this scenario, a Martian is observing earth and decides…

  • Investigation: Model Enzyme Activity with Toothpicks

    Investigation: Model Enzyme Activity with Toothpicks

    Use toothpicks to model enzymes. Explore substrate and enzyme concentrations by changing toothpick numbers. Model competitive inhibition by taping fingers.
