Every investigation starts with a question about something real—something students can see, wonder about, and try to explain. These phenomena ground learning in shared experiences and help students stay curious from start to finish.

Reading, writing, talking, and using math are woven into every investigation. Students read to gather information, write to explain their ideas, and talk with their peers to refine their thinking.

Students work together to collect data, share ideas, build arguments, and offer feedback. Collaboration isn’t an add-on—it’s part of the learning process at every stage.

You can use our investigations to supplement your current curriculum, strengthen a unit, or address a standard you may not cover elsewhere. Each one is a complete, stand-alone learning experience that brings science to life.

Students use science and engineering practices, core disciplinary ideas, and crosscutting concepts together to figure things out. Instead of memorizing vocabulary, students build understanding through hands-on exploration and sense-making.

Our materials are built to give every student a fair opportunity to learn and participate. All students are encouraged to contribute their ideas and experiences, which helps create a classroom culture where everyone sees themselves as a scientist.

All of our investigations follow the Argument-Driven Inquiry (ADI) instructional model, developed through classroom-based research and shaped by teacher feedback. Each investigation is aligned with NGSS and state standards, so you can be confident they support your curriculum.
