The Wonder of Science - Paul Anderson created an excellent resource for understanding the standards and finding aligned assessments. Use the State View Menu to find NYSSLS-specific standards (like HS-ESS1-7).
My Nasa Data - a fantastic site for finding authentic stimuli (maps, data sets, etc). I particularly like the Data Literacy Cube worksheets and these satellite images.
Scott Azar's NYSSLS ChatGPT Bot - Scott made an innovative chatbot to help write clusters aligned to the new standards. It does get a little confused on the non-NGSS NYSSLS ones. I like using it to reword questions or to come up with additional questions that connect to a stimulus.
Science by Tiff's TPT - Tiffany's materials are high quality and NGSS/NYSSLS aligned. When I need something I don't want to make from scratch, I go here! I used her ESSRT worksheets this year.
CEEE - Center for Education, Engagement, and Evaluation - I have used a few of these resources, which have all been extremely high quality and a great fit for NYSSLS. I really like the Data Puzzles!
