# Next Generation Science Standards Explorer

Are you a STEM, STEAM, and/or science teacher looking for great edtech for the Next Generation Science Standards (NGSS)? Browse hundreds of apps, games, and websites evaluated by our expert reviewers and tagged for relevant Performance Expectations (PEs).

To find the right tool for your NGSS-aligned activities, lessons, and curriculum: select a grade, choose a topic, and then find the PE that interests you. Click the green arrow on the right-hand side of the PE to see a list of suggested tools. Just below each PE you'll see three NGSS dimensions – Science and Engineering Practices (SEP), Disciplinary Core Ideas (DCI), and Crosscutting Concepts (CC) – for quick and easy reference.
