Welcome to PRISMS Home
PRISMS is a collection of reviewed phenomena and representations for middle school. Our goal is to help increase the amount of content aligned and pedagogically useful resources available in the National Science Digital Library (NSDL) for middle school teachers and students.
Resources are evaluated for how well they support learning goals in Science for All Americans, Benchmarks for Science Literacy, and the National Science Education Standards and are grouped in the main menu by categories used in the Science Curriculum Topic Study.
What are phenomena?
"Phenomena" are real-world objects, systems, and events that provide evidence of key ideas in science. A phenomenon may be experienced first hand or vicariously.
What are representations?
"Representations" are diagrams, models, animations, simulations, and analogies that can help clarify key ideas in science.
