  • Squid Dissection for Beginners

    Squid Dissection for Beginners

    External and internal anatomy of the squid with directions for dissection and identifying structures.

  • Investigation:  Modeling Diffusion

    Investigation: Modeling Diffusion

    This inquiry investigation requires students to cut agar into 3 shapes (small, medium, large) and compare the rates of diffusion.

  • Introduction to the Light Microscope

    Introduction to the Light Microscope

    Students learn to use a basic light microscope by examining the structures and using a prepared slide of the letter “e” to practice focusing.

  • Comparing Plant Cells

    Comparing Plant Cells

    Students observe onion cells and elodea cells using the light microscope. Students compare structures found in each type of cell and create drawings.

  • Observing Human Cheek Cells with a Microscope

    Observing Human Cheek Cells with a Microscope

    In this lab, students use a toothpick to get a sample of cells from the insides of their cheek, stained with methylene blue.

  • Growing Sponge Animals

    Growing Sponge Animals

    This simple activity provides an introduction to laboratory techniques and data collection. Students measure how a sponge animal toy grows when submerged in cold and warm water.

  • Investigation:  What Are the Processes of Science

    Investigation: What Are the Processes of Science

    Inquiry investigation where students develop hypotheses to answer a question about lung capacity, design an experiment, collect data, and draw conclusions.

  • Scientific Method Scenarios

    Scientific Method Scenarios

    students work in groups to develop an experiment that answers a question. Students design the experiment, and must also identify the a control group and the independent and dependent variables in their experiment.

  • Population Biology with Paramecium

    Population Biology with Paramecium

    Activity illustrates the competitive exclusion principle by showing students how each population behaves when grown alone or when mixed together.

  • Removal of the Frog’s Brain

    Removal of the Frog’s Brain

    This worksheet provides instruction for removing the brain and reveal the lower leg bones, which include the femur and the tibiofibula (fused tibia and fibula).

  • Examining the Fossil Record

    Examining the Fossil Record

    During a unit on evolution, students learn a little about geologic time and how we use the fossil record to establish lineages.  In this project, students cut out pictures of fictional fossils and arrange them on a chart to show how one species become two species.   The activity includes a description of phyletic and…

  • Lab Safety Cartoon

    Lab Safety Cartoon

    This cartoon depicts students engaging in safe and unsafe activities.  It is a good starting point for a discussion on lab safety.

  • Sheep Brain Dissection Guide

    Sheep Brain Dissection Guide

    The brain is one of the most interesting dissections to perform, mainly because all of the structures are easily found and animal models closely resemble human brains..  In this lab guide, students are given instruction on how to remove the dura mater,  and locate the main structures of the external brain

  • Scientific Method and the Simpsons

    Scientific Method and the Simpsons

    NOTE: This is a new version of this activity, with new stories!  Old Version: Scientific Method and the Simpsons This activity requires students to read stories where experiments were performed by members of the Simpson’s family.  The stories are intended to be humorous. Students must identify the manipulated and responding variables (independent and dependent), the…

  • Human Traits Bingo

    Human Traits Bingo

    This activity is a good starter for genetics units.  Students are often fascinated by traits that are visible.   Lively discussions of human genetics will often include students asking tons of questions about what they view as “oddities.” Though, many of those traits would be difficult to establish as strictly genetics, it provides a good…
