This site’s evolution lab makes phylogeny and evolutionary history accessible to all students while scaffolding an understanding of the fossil record, the role of DNA in evolution, and an introduction to biogeography. Kids can also play the role of a molecular engineer by solving RNA folding puzzles.

Developed by a high school teacher, Biology Corner includes curated resources from around the web paired with extra practice and presentations and as well as ready-to-use investigations.

If you need a template for lab reports, ideas for your biology club, pacing guides or lessons for biology, Pre-AP Biology, or AP Biology, this is a good place to start.

Thoroughly covering all of earth science, including meteorology, oceanography, and astronomy, this site’s investigations take students through a series of pages that incorporate reading, animations and real data to introduce or extend topics.

Search through this great collection of hundreds of categorized ready-to-use handouts, labs, and lectures submitted by physics teachers. You’ll find resources on the conservation of energy and momentum, electromagnetism, fluid mechanics, and more!

With a curriculum corner, question bank, lab area, and a NGSS-devoted page, this is a valuable resource is among the best science websites for K-12—including distance learning!

Chemdemos are virtual interactives for more advanced chemistry students complete with particulate models and real-time data help you get through labs that you may not have sufficient materials to complete. They can also give your students extra practice at home before or after “wet” labs.

Like most chemistry sites, virtual labs and lesson plans are freely available, but ChemCollective stands out with their scenario-based activities and forensics tie-ins with activities like the “Mixed Reception ” Murder Mystery.

One of the best resources for Chemistry teachers nationwide, the AACT produces consistently high-quality resources including labs, demonstrations, and activities. The best part is that their materials are organized by grade and topic—including options for elementary school teachers, too.
