WATER QUALITY FOR FRESHWATER ORGANISMS
Students use determination of dissolved oxygen and water temperature changes to determine the environmental impact from thermal pollution.
Curated OER
Reading the River
In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Natural Selection in Action
Students demonstrate natural selection through a lab activity. For this biology lesson, students explain how natural selection leads to speciation. They complete their lab report and discuss results in class.
Curated OER
Invertebrate Classification
Students discuss the recent disovery of the "furry lobster" to peak interest in the animal kingdom. They classify various speciments using invertebrate dichotomous keys, identifying major animal phyla and classes. Thy the complete the...
