NGSS Network Explorer

Graphically explore and identify the Next Generation Science Standards and their relationships

The Next Generation Science Standards (NGSS) comprises a set of more than 800 standards which maintain more than 2000 relationships with each other. When displayed as a network, we can make exploring the NGSS flexible and interactive.

Some NGSS Explorer features

Whereas in the NGSS Performance Expectations (PEs) and Disciplinary Core Ideas (DCIs) have individual identifiers/codes, Science and Engineering Practices (SEPs) and Crosscutting Concepts (CCs) do not have such identifiers. Of course, if you click them, they will identify themselves with their text. Double-click them and they display their own subnetwork.

Whenever a network involves more than a single grade or grade band, the involved grades are shown as nodes in the network. Here, for instance, we see that Engineering Design standards are distributed over each of the four NGSS grade bands: grades K-2, 3-5, 6-8, and 9-12 with no finer grade distribution within the grade bands.

Single-clicking standard nodes highlights them on your screen in a separate space adjacent to the network (not shown here). Double-clicking them makes them generate their own subnetwork. Networks can be shown in different geometries and at different depths.
