Curated OER
Microbes and Climate
Pupils examine how microbes play a role in the climate system. In this climate lesson students complete an activity, create a PowerPoint presentation and present it to the class.Â
Curated OER
Through A Pinhole
Learners construct a pinhole camera using their knowledge of the physics of light. This interdisciplinary activity give students hands-on experience in understanding the production and processing of photographic images.
Curated OER
A Watershed Monitoring Module
Students explore the relevance of water quality monitoring in relation to a local wetland ecosystem. They conduct standard water quality tests using wet tests and CBL calculators and probes. Student record and interpret the results.
Curated OER
Bioinformatics
Students are exposed to the tools and databases currently used by researchers in molecular and evolutionary biology. They gain a better understanding of gene analysis, taxonomy, and evolution.
Curated OER
Invent PCR: You May Win a Nobel Prize
Students gain an appreciation for the simplicity, but also complexity and elegance of PCR. They comprehend all components of the protocol. Students explain exactly how CPR works, and why, after the third cycle, the predominant DNA being...

Microbial Spoilers: The Impact of Microorganisms on the Shelf-life of Milk
Students are inroduced to a commonly used microbial culturing technique. They explore the role of microorganisms in determining the shelf-life of food products.
Curated OER
Operating the spectrophotometer
Working in small groups, students explore the operation of spectrophotometer. Using the spectrophotometer, they investigate Beer's Law with everyday items.
Curated OER
Global Awareness
Students read about how scientists are arriving at current theories of human origin and migration through mitochondrial DNA analysis. They then piece together a map showing the data from mitochondrial DNA analysis to plot the migration...
Curated OER
Creatures in Torch Lake
Students investigate pond ecology. They gather water samples from various sources, add grass, and let it sit for a week. Afterward, using microscopes, they identify the microorganisms present in the sample.
Curated OER
Selecting Soil Organisms in Compost
Students 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 the...
