  • Predator Prey Simulation

    Predator Prey Simulation

    Interactive program allows students to manipulate the type of organisms within a system and what they eat.

  • The Tardigrade Project

    The Tardigrade Project

    This project was created for AP Biology students where they scrape lichens from trees near campus and filter them over night so that tardigrades and other microorganisms can be collected from the water.

  • Deer: Predation or Starvation?

    Deer: Predation or Starvation?

     This activity asks students to calculate the population change (births – deaths) and then graph the number of deer and the number of wolves. 

  • Measuring Biodiversity Using Beans

    Measuring Biodiversity Using Beans

    Students analyze a community of beans (pinto, lima, navy) to determine the richness, abundance, and biodiversity index of two communities. 

  • Random Sampling

    Random Sampling

    Students model how field biologists would use a sampling technique to estimate the number of sunflowers in a field.  First, they choose 10 plots at random by choosing paper slips, then take the average of those plots.  The worksheet walks them through the steps of then using the average and the overall size of the…

  • Calculate the Biodiversity Index of a Beach

    Calculate the Biodiversity Index of a Beach

    This activity asks students to sort seashells and calculate the Simpson’s biodiversity index.  The calculation is based on the number species in an area, dependent upon richness (number of unique species) and abundance (number of individual species).

  • The Lesson of the Kaibab

    The Lesson of the Kaibab

    This activity asks students to graph the number of kaibab deer on the plateau after predators were removed, then analyze data and develop a better plan.

  • Niche Partitioning – Gorongosa Phenomenon

    Niche Partitioning – Gorongosa Phenomenon

    Explore niche partitioning in Gorongosa with this interactive graph and activity.

  • Ecology Lesson on Trophic Cascades

    Ecology Lesson on Trophic Cascades

    This year I decided to change the way I teach the last unit of the year, which is ecology.   Our textbook is really old, and not aligned to NGSS.  The lessons followed a familiar “old-school” pattern:  take notes mainly about definitions, do an activity or lab, then take a quiz.  This year, I wanted to…

  • Biome Project

    Biome Project

    Students become experts in a biome and create a product, such as a pamphlet, to showcase details about their assigned ecosystem (tundra, forest, ocean..etc.)

  • Investigation:  What Factors Affect Seed Germination?

    Investigation: What Factors Affect Seed Germination?

    This activity can be used as part of a unit on plants or as an activity to illustrate the scientific method.  The materials are cheap and can be obtained from the grocery store.  Students design an experiment to determine what factors affect seed germination.   They are given a list of variables that are appropriate…

  • Investigation: What Organisms Are Found in Ponds?

    Investigation: What Organisms Are Found in Ponds?

    Does your community have ponds, streams, or lakes?  Students enjoy working with real biology, and though it may not be possible to take students to a lake, you can bring the lake to the student.   This open-ended activity gives students the opportunity to explore pond water and compare the types of species found in…

  • Color the North American Biomes

    Color the North American Biomes

    This coloring activity is suitable for beginning biology students who are learning about the plants and animals found in each major biome.  The worksheet does require a basic geography knowledge, which I found somewhat lacking in my freshman students.   I usually place a large map of North America on the overhead projector for students…

  • 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…
