How Do We Clean Polluted Water?
How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...
Curated OER
Fish and Oxygen
Students explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.
Curated OER
Efficiency Means Getting More for Less
Students measure water and make predictions about efficiency.
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
Teaching About the Properties of Water
Students use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.

On the Microbe Trail: Bacteria and Aseptic Technique
Students pour, label, streak, seal and store plates in an incubator. They identify areas in their environment that provide a rich fauna of microbes once they have been swabbed. They identify areas of contamination through a laboratory...
Curated OER
An Introduction to Microbes and Microbes Are Everywhere
Seventh graders define the term microbe. They identify the five main groups of microbes. Students give examples of ways in which microbes have impacted or currently impact human life. They create a hypotheses for where they expect to...
Curated OER
Bacteria in Drinking Water And Water Purification
Students explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth from...
Curated OER
Mitosis And the Cell Cycle
Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.
Curated OER
The Great Fossil Find Hypotheses
Students are taken on an imaginary fossil hunt. Following a script read by the teacher, students find (remove from envelope) paper fossils of some unknown creature, only a few at a time. They attempt to reconstruct the creature.
Curated OER
Insects Are Helpful!
Students see that insects do lots good and are very valuable to humans and nature. This is part of an ongoing effort to dispel fears of insects. They rotate through a series of centers that have examples of how insects contribute to our...
Curated OER
Tobacco and Organisms
Students work in teams to design and carry out experiments which show the effects of tobacco / nicotine on organisms. They write reports which are submitted to "The Company" and prepare oral reports which are presented to the class.
Curated OER
Population Vs Consumption: Which is a Bigger Problem for the Environment & Who is Getting the Lion's Share of the World's Resources?
Students develop critical thinking and awareness about the complexity of natural resource use, wealth distribution, population densities, poverty, and the environment. They think about people living in different parts of the world and...
Curated OER
Family Pedigrees
Young scholars work as a class to first construct a pedigree of a popular singer, showcasing the singing gene being passed down through the generations. Students then make their own family pedigree and follow two traits through their...
Curated OER
Permeability of Earth Materials
Students observe and classify the permeability of a variety of materials.
Curated OER
Wait, They Can do it by Themselves?
Learners recognize the concepts of evolution and natural selection as well as cladistics and phylogenetics. They observe the process of regeneration in a sea anemone to simulate asexual reproduction.
Curated OER
Invertebrate Research Project
Students keep a scientific research notebook on an invertebrate detailing its behavior and responses.
Curated OER
Who's Who and How Do You Know for Sure?
Students investigate the applications of DNA fingerprinting, They read crime scenarios and using the details of the crime and laboratory experimentation decide the suspects guilt or innocence.
Curated OER
Inquiry-based Investigations into Pond Water Microorganisms
Students become familiar with common microorganisms and experience exploring the microbial world.
Curated OER
Hominoid Skull Comparison
Students are provided with evidence used to support evolutionary theory. They are introduced to classification by using primates as an example. Students read article related to Hominoid Skull Comparison and write a summary about the...
Curated OER
Ground Level Ozone
Students analyze real-time data and predict the level of ground ozone in their home city. They measure the level of ground ozone, submit their data to an online collaborative project, and create a web page presenting the dangers of...
Curated OER
Organs to Go...
Students explain the principles of experimental design and reinforce the steps of the scientific method. Each group of students create a "slush" type mixture to store a chicken liver.
Curated OER
Remote Control
Students explore and evaluate several distance learning Web sites. They defend whether or not they would like to participate in the distance learning experience by either writing a proposal for including this distance learning project...
