Drifting Downward
Learners study the effects of different salients and temperatures on vertical movement of an organism. For this experimental lesson students design different shapes of foil to simulate drifting planktonic organisms.
Curated OER
Selecting Soil Organisms in Compost
Young scholars conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine...
Curated OER
Termite Lab
Students examine insect behavior in a lab activity. Students explore the idea of chemical specificity and the reactions of termites to a chemical found in their trail pheromone. Students watch a demonstration with termites before...
Curated OER
Fish and Oxygen
Pupils explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.
Curated OER
Benthic Macroinvertebrates
Learners 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
Science: Put Your Heart into Engineering
Students examine the heart and vascular system and the need for artificial valves. After explaining how heart valves function, they design their own heart valves for experimentation. They predict the speed of fluid flowing through...
Curated OER
Effects of Seed Soaking on Germination
Students explain the standard growth pattern of a monocot seedling and word process a finished essay.
Curated OER
Field Experiments on Succession
Student develop a hypothesis regarding the effects of either mowing or fertilizer upon the diversity of plant species in a grassland ecosystem. They set up experiment field plots and measure species richness.
Curated OER
Mass vs. Weight
Students make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass lesson, students weigh both an empty beaker and beakers with various amounts of weight inside of them in order to find...
Curated OER
Age Structure Studies
Students collect data from Internet sources to compare age distributions in their city, county or state with that of other places in the US or other countries. They construct and interpret age-structure population pyramids and research...

Genome: The Secret of How Life Works
Young scholars become aware that genetic issues impact many areas of life, such as medicine, food and agriculture, and law. They become aware that there are many ethical issues related to genetics.
Curated OER
Superbugs
Students research deep sea communities and discover strategies for combating antimicrobial resistance and write reports on it. They consider overprescription and prophylactic uses of antibiotics as causes for their ineffectiveness.
Curated OER
