The Biomass Balancing Act
Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...
Curated OER
Earthworm Movement and Landscape Structure
Students describe differences in animal usage of habitats depending upon successional status of site. They also design other experiments to test movement patterns of animals through habitats of differing structure.
Curated OER
Sustaining Life Under the Ice
Students design and conduct experiments in order to identify the components of lake water environments that are affected by winter ice cover. They use the experiment results to propose effective human management of these ecosystems.
Curated OER
Bioremediation
Students design and conduct investigations that illustrate the effect bioremediation has on organic matter and determine environmental applications. They, in groups, present their findings to the class.
Curated OER
Inquiry into Heat Loss and Insulation
Pupils design an experiment to test the problem of the porridge in Baby Bear's bowl as being just right while the other porridge was either too hot or too cold. They explain the steps of their experiment and record their observations and...
Curated OER
Mixing Up Magic
Students explore the relationship between art and science through experimenting with color, design and recycled materials and creating their own art work.
Curated OER
Antisense Oligonucleotide Therapy
Students conduct Internet research on Antisense Oligonucleotide Therapy. They design a puzzle to represent these processes, read and summarize an article, conduct research, and design a theoretical experimental procedure.
Curated OER
Towel Testing
Students examine how to design and implement experiments. In this paper towel experiment activity students test the strength of paper towels.
Curated OER
What Goes Up Must Come Down!
Students hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...
Curated OER
Teaching Biology Through Problem-based Activities
Students plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.
