  • Investigation: Villi Height

    Investigation: Villi Height

    Use a Netlogo simulation to observe how different heights of villi within the intestine affect absorption rate. Change the height of villi or size of food.

  • Dog Tales – NOVA

    Dog Tales – NOVA

    Worksheet for the NOVA program “Dog Tales” which explores the evolution and domestication of dogs. Includes multiple choice questions with a final reflection.

  • Horse Genetics

    Horse Genetics

    Practice genetic crosses with horse traits. The gait-keeper gene controls whether a horse will trot or pace and the flaxen gene determines mane color.

  • Genetic Crosses – 2 Traits

    Genetic Crosses – 2 Traits

    This worksheet was designed for freshman learning dihybrid crosses. Students struggle with setting up Punnet squares, so the squares are set up for them at first. Students only need to fill in the letters of the genotype can determine the phenotype proportions. A final task requires students to set up their own 4×4 square when…

  • 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.

  • 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.

  • 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…

  • Reinforcement: Biomolecules

    Reinforcement: Biomolecules

    This worksheet is used with a unit on biological molecules in an introductory biology class. Students match definitions or descriptions to words provided in a word bank. The anchoring phenomenon in this unit is hagfish slime, which explains the inclusion of this concept in the list. Google Slides and Student Notes for the unit are…

  • Reinforcement: Cell Transport

    Reinforcement: Cell Transport

    This reinforcement worksheet was designed for introductory biology, to help students learn concepts related to cell transport across the membrane. Words include osmosis, diffusion, hypertonic, and hypotonic, semipermeable, and active and passive transport. The exercise has vocabulary terms and a list of sentences or definitions for students to match to the words. I use google…

  • Cell Membrane Coloring

    Cell Membrane Coloring

    Color the cell membrane with a focus on diffusion, osmosis and transport proteins. Students color the structures of a cell membrane according to the directions. Then they answer questions about cell transport. I designed this worksheet for an introductory biology course to reinforce concepts related to cell transport. An image shows the phospholipid bilayer with…

  • Genetics of Chicken Combs

    Genetics of Chicken Combs

    The combs of chickens are controlled by four alleles, which interact to produce four distinct phenotypes: single, rose, pea, and walnut. In this exercise, students predict the outcomes of chicken crosses. Ideally, students should already know how to do crosses that involve two traits, the mechanisms for solving these problems are similar. My honors biology…
