The CLEAN collection of teaching/learning resources is now indexed to enable you to quickly and easily find resources for Middle School and High School that are aligned with the NGSS. There are multiple ways you can search the collection using NGSS

1. NGSS browse – a user-friendly search portal into the collection
2. NGSS at a Glance – overview of all NGSS standards that are relevant to climate and energy with clickable resource links
3. Use the regular search interface and use the filters on the right. 

If you loose any of these links there are now buttons at the top of the collection interface. 

Also – below is a link to the recording of NAGT/AGI’s webinar: NGSS Climate Education with the CLEAN Collection
