Will Global Warming Push Trees to Extinction?
Students examine the extinction of plants and animals through loss of habitat. They investigate the effects of global warming. They use a computer model to analyze the impact of global warming on tree growth and distirbution...
Curated OER
Making a Brassica Model
Students apply skills they have learned to construct an accurate model of the Brassica and then work together on a group project. They analyze how the parts of a system go together, and how these parts depend on each other. Finally,...

What Turns Seeds On?
Learners design, implement, and report a scientific research project using the scientific method. They explain the experiment and its findings through poster, essay , or other presentation method.
Curated OER
Investigate Non-native Neighborhood Invasion Species
Students investigate non-native species that are invading local or state environments. They choose one species to research and report on.
