Curated OER
Demonstrating an Epidemic
Young scholars use an experiment that allows them to experience a small scale "epidemic", demonstrating the ease with which disease organisms are spread. Students determine the originator of the epidemic. They transfer live bacteria by...

Using A Winogradsky Column to Analyze Microbial Communities
Young scholars use easily obtained materials to study ecological succession in a microbiological community. This investigation is appropriate for a variety of age groups. Elementary Students be fascinated by the changes occurring over...
Curated OER
The Global Impact of Insect Borne Diseases & Agriculture
Students study the global impact of insect borne diseases, the appropriate use of pesticides, and the concept of human interrelations on a world wide scale. They examine how to safely apply a pesticide, according to the label.
Curated OER
Some Like It Hot, Some Like It Cold
Students are explained that thermophiles are organisms that have optimal growth temperatures above 50oC. They investigate the temperature ranges for the growth of common bacteria. Students answer the question of do either of these...
Curated OER
Drifting Downward
Students study the effects of different salients and temperatures on vertical movement of an organism. In this experimental lesson students design different shapes of foil to simulate drifting planktonic organisms.
Curated OER
It's All in Your Mind
Students investigate the definition of memory. In this memory instructional activity students investigate strategies to improve memory as well as examine what the difference is between a short-term memory and a long-term memory.
Curated OER
Life in Streams and Ponds
Students collect microorganisms, demonstrate correct laboratory/Gram stain procedure, and design and construct tables to organize data.
Curated OER
Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
Curated OER
Investigating the Biosphere with Planetary Models
Students model the biosphere and manipulate variables affecting change and plan their experiments with the help of others. They describe their question, hypothesis, and methods of investigation.
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
Curated OER
Effects of Seed Soaking on Germination
Learners explain the standard growth pattern of a monocot seedling and word process a finished essay.
Curated OER
Benthic Macroinvertebrates
Students survey and describe a stream ecosystem. They sample the benthic macroinvertebrate populations of a given stream and determine community structure through the use of the Chandler Index and a species diversity index.
Curated OER
Swinging on a String
Students explore how pendulums work and why they are useful in everyday applications. In a hands-on activity, they experiment with string length, pendulum weight and angle of release.
Curated OER
Population Dynamics of Growth of Drosophila
Young scholars experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Students demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
Curated OER
E.coli and their Human Environment
High schoolers observe how environmental changes (antibiotics) can affect the growth of E.coli, the rod shaped intestinal bacterium. They use the "F" test for statistical analysis. Students
Curated OER
Population Dynamics of Growth of Drosophila
Young scholars investigate population dynamics such as variation in density of females, composition of food sources an environmental factors such as light and temperature on Drosophila. They then relate their findings to human...
