How Do Organisms Vary?
Students study variation of organisms. They determine this variation arises from genetic and environmental causes.
Curated OER
Where Do I Belong?
Tenth graders study the diversity of life in the world. They classify and sketch organisms into the 6 kingdoms.
Curated OER
Down, Dung and Dirty
Students investigate the stages of succession in animal dung communities. They create a dung culture using fresh cow, goat or horse dung then record data on the fungal species that appear over a two week period.
Curated OER
The Water Detectives
Students collect water samples from designated sampling stations, and discuss water pollution. They analyze the water samples, record the data on a spreadsheet, and present the environmental water quality data to the class.
Curated OER
Fish Parasite Survey
Students survey and dissect as many fish as possible. They count nematodes, cestodes and crustaceans on the fish, fill out autopsy reports, and transfer data to a chalkboard data table. Students graph the results of the entire class...
Curated OER
Fish Parasite Survey
Learners count nematodes, cestodes and crustaceans on approximately one-hundred and fifty fish. They fill out autopsy reports for external and internal parasites then complete and discuss guide questions to make inferences about parasite...
Curated OER
Introduction to Mendelian Genetics using Fiction
Students investigate Mendelian Genetics by studying the history of Mendel and what it was like to be a 19th century scientist. They read a pieces of fiction during this investigation.
Curated OER
Monitoring Aquatic Ecosystems Lesson Plan
Students perform an experiment to test the quality of the water in a marsh.
Curated OER
Pollution Solutions
Learners visit a local park to test the quality of the aquatic environments. They search for sources of pollution and examples of pollution control. Based on their obeservations and experiments, they rate their local environment.
Curated OER
Rates and Causes of Mortality in Classroom and Wild Monarch Larvae
Pupils observe, record and analyze the mortality rates of the monarch larvae that are being held in a controlled environment versus those that are in the wild.
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
Great Gravity, Batman!
Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...
Curated OER
Zebra Mussels and Water Pollution
Research the proliferation of zebra mussels and their effects on local bodies of water. The class obtains zebra mussels and examines them, identifying their basic structures. They brainstorm ways the mussel may have been introduced to...
Curated OER
Water and Ice
Students observe what happens to water as it goes from a solid to a liquid. In this exploratory lesson students gain an understanding for the water cycle while working in groups observing what happens to water as it changes...
Curated OER
Become an Expert
Students practice their researching techniques by preparing a presentation with little notice. In this information research lesson, students utilize the Internet to research one of several subtopics concerning panthers....
Curated OER
Sequence Alignment
Students explore the uses of sequence alignment. In this DNA lesson students complete several experiments on sequencing and algorithms.
Curated OER
How do new species form?
Tenth graders conduct a critical analysis of current evolutionary concepts. They describe how scientists continue to investigate theories. Students examine examples with experimental data that suggest alternative methods of species...
Curated OER
Molecular Approaches to Evolution
Students are introduced to working with molecular data. The first activity does both simulated and original data are used to compare amino acid, protein or DNA differences to construct phylogenetic trees or cladograms. These activities...
Curated OER
Natural Selection
Students practice calculating allele and genotype frequencies in the framework of a simple simulation using hard candy, calculators, and a worksheet. This instructional activity includes a three-page worksheet and an assessment question...
Curated OER
Feeling Crabby?
Students analyze data to investigate the influence of water depth on size among deep-water crabs. They interpret results from this data, and apply the results regarding appropriate fishery regulations.
