The National Science Teachers Association website is a useful tool for teachers to use as they assist students in prepping for their local Terra Fair. On the NSTA website teachers can find over 800 classroom resources-including lesson plans, book chapters, videos, simulations and more- on a variety of topics for every grade level from K-12. Many of these classroom resources are free to download and implement into your own classroom. Each resource is vetted by NSTA curators, and easily adaptable to be in line with Next Generation Science Standards (NGSS).
In addition to classroom resources, NSTA also publishes a variety of newsletters, including a monthly publication called Science and the STEM Classroom that highlights important topics in STEM education and provides a variety of supplemental resources. There are 3 versions of this newsletter published for different grade levels; one for elementary school, middle school, and high school/college. Each issue is archived and available online to read.
This website can prove to be a useful resource as you guide students through fair preparation. Science Buddies and our Pinterest page are good resources for them to use as they create their projects, and begin project boards. Our blog posts also have resources for students including video guides on judging and creating project boards.
