This activity is a field investigation where students will discover that everyone can be a scientist.
This Starting Point Teaching Collection page describes the Yellowstone Fires module created for NASA's Classroom of the Future. Emphasizing an integrated approach to environmental earth science through problem-based learning, the module asks students to assume the role of environmental biologist, and help several government agencies resolve the debate surrounding "let it burn" policies in national parks. The government agencies would like to know whether or not to allow naturally occurring fires in Yellowstone National Park to burn to their natural conclusion. The agencies are particularly interested in student recommendations based on an Earth System Science analysis of a fire's impact on the air, land, water, and living things. Many of the pages within the module site provide hyperlinked background resources to investigate wildland fire issues in more detail. A glossary, references, related links, and a general description of the problem-based learning model compliment the site. On this page, teachers can find learning goals, teaching notes and tips, teaching materials, assessment hints and references and resources dealing with this exercise. It also describes the context in which the module is best used.
In this segment from Curious, scientists conduct an experiment to learn how different areas of the brain are stimulated when making moral decisions.
Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!

Students investigate one trait in heredity, using models and quick results with a computer-generated game. Students have practice in predicting and creating solutions to specific heredity questions. The game becomes increasingly more challenging as it progresses.
