    pH and Buffers

    Use a water quality sensor to measure the pH of buffers and the differences in pH values of various household products.

    Plant Pigments and Photosynthesis

    Use a colorimeter to determine the rate of photosynthesis in a suspension of chloroplasts.


    Bacterial Transformation

    Use the tools of biotechnology to transform competent E.coli cells and then select for antibiotic resistance.

    Mitochondrial Genetics and Biotechnology

    Use restriction endonuclease digests and agarose gel electrophoresis to diagnose an inherited mitochondrial disease. **Requires Mitochondrial DNA Kit (BP-6946)**


    Evolution and Population Genetics

    Use the Hardy-Weinberg equations to solve genetics problems.

    Genetics of Organisms with Drosophila melanogaster

    Use the common fruit fly, Drosophila melanogaster, to create and statistically analyze genetic crosses.

    Mitosis and Meiosis

    Use a microscope and prepared slides to explore the stages of mitosis and meiosis.

    Animal and Plant Physiology

    Animal Behavior

    Use a choice chamber to measure an organism's preference for different
    environmental factors.

    Endotherms and Ectotherms: Temperature Regulation in Animals

    Use a carbon dioxide gas sensor to explore how an endotherm and an ectotherm regulate internal temperatures by measuring the respiration rates of two different organisms exposed to varying temperatures.

    Physiology of the Circulatory System

    Use a sphygmomanometer or blood pressure monitor and a heart rate sensor to measure the changes in the blood pressure and heart rate of a patient in different body positions. Use a temperature probe to measure the changes in heart rate of Daphnia magna under different temperature conditions.

    Reflex versus Reaction

    Use a ruler, stopwatch, and reflex hammer to measure and compare human reflexes and reactions.


    Use a barometer to explore the effects of environmental factors, such as air movement, on the rate of transpiration in a plant.


    Air Pollution and Acid Rain

    Use a water quality sensor to measure the effects of CO2, SO2, and NO2 on the pH of water.

    Dissolved Oxygen and Primary Productivity

    Use a temperature probe and a water quality sensor to measure the effects of temperature on the dissolved oxygen concentration of water. Use a dissolved oxygen sensor to measure the effects of light intensity on the photosynthetic activity of algae.

    Elodea and the Snail

    Use a water quality sensor to measure pH changes in a series of simulated closed systems containing various organisms.

    Interrelationship of Plants and Animals

    Use carbon dioxide and oxygen gas sensors to measure changes in gas levels in a terrestrial ecosystem created within a PASCO EcoChamber.

    Population Ecology

    Use a colorimeter to explore the effects of habitat size, nutrient availability, initial population density and temperature on the growth rate of E.coli bacteria.
