"Using Cichlids To Demonstrate the Effects of Human Activity On Ecosystems"
Young scholars explore the freshwater ecosystem of Africa's Lake Victoria by creating a freshwater aquarium. They investigate factors affecting the aquarium's ecosystem and conduct lab activities.
Curated OER
Hardy-Weinberg Equilibrium According to Hoyle:
Young scholars gain a feeling for the significance of the Hardy-Weinberg Equilibrium without using algebra but participating in an interactice game.
Curated OER
Habitat Dynamics
Students develop an interactive diary to record bird seed consumption. In this habitat lesson, students predict and record the amount of birdseed eaten each week by birds.
Curated OER
Norman Suburban Activity
Students analyze the factors affecting organisms in the pond ecosystem. In this environmental science instructional activity, students perform an experiment to determine pH, nutrients and temperature of different pond sites. They present...
Curated OER
Cactus Wheel
Students explore plant biology by conducting field experiments outside of class. In this desert plant lesson, students discuss how cacti thrive in such dry climates and how dense their populations are. Students utilize action cards, a...
Curated OER
Lake Pepperidge Farm
Students calculate proportions to determine the total population of Lake Pepperidge Farm. They collect a blind sample of fish and count the number of tagged and untagged fish. They collect data from all samples and record the data in a...
Curated OER
Leaving Home
Students explain the importance of larval dispersal and retention to populations. They collect data on organisms and examine it.
Curated OER
The Evolution of Canis pedatus
Students examine the given characteristics of a previously unknown dog-like creature, Canis pedatus, to decide if the creatures would survive when relocated to a new environment. They work in small groups to decide whether or not the...
Curated OER
Camouflage and Protective Coloration: A Model of Natural Selection
Students collect data and compare whether protective coloration or camouflage provides better biological fitness in a given environment. They simulate predator prey interactions of two different species and use gene frequencies to...
Curated OER
Composting
Eighth graders collect data from Bottle Biology compost columns and record using Excel spreadsheet.
Curated OER
Biotic Factors
Students identify individual organism, a species, and a population within the study community. They identify biotic factors at the site and attempt to characterize the site's species diversity.
Curated OER
A Model for Natural Selection- Spaghetti Worms
Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...
Curated OER
Creative Ways To Teach Evolutionary Concepts
High schoolers explore evolutionary concepts in cartoons and lab activities. They describe and explain evolutionary concepts featured in a cartoon and participate in laboratory activities.
Curated OER
Exploring Ecology
Students explore the basics of ecology through numerous hands-on and relevant activities. They participate in an online food chain demonstration, which explores food web dynamics. They dissect owl pellets, examine the prey's bones, and...
Curated OER
Allele Frequencies and Sickle Cell Anemia Lab
Students investigate how selective forces like food, predation and diseases affect evolution. In this genetics instructional activity, students use red and white beans to simulate the effect of malaria on allele frequencies. They analyze...
Curated OER
Pollen Collection And Identification
Students investigate plant reproduction, pollen collection and identification. They collect pollen samples over a twenty four hour period and examine them under a microscope.
Curated OER
Evaluate Ecosystems
Ninth graders conduct an environmental inventory on one ecosystem. They collect data, and write an environmental impact statement on that area. Students explain the interactions between different systems found within an ecosystem....
Curated OER
The Lynx Eats The Hare
Students investigate the predator and prey relationship. This is done using a simple simulation. The simulation is done as an arts and craft activity. Students record data and track it using a graphic organizer and then they discuss the...
Curated OER
Role of Cerci in Escape Responses of the Cockroach
Students investigate the changes in escape behavior in Madagascar Hissing Cockroahes when their sensory apparatus is removed. They use puffs of air at differnt angles to simulate a predator's approach then collect and analyze data on...
