So many classes are moving to distance learning and science may be one of the harder subjects to master. It’s not easy to tackle biology and chemistry lab experiments from home! These websites will help supplement material in all middle and high school science subjects. Jump to your field of study:


Best Science Websites for Teaching Biology

HHMI Biointeractive

best science websites high school

You may be familiar with HHMI’s free movies and posters, they also offer films that are available to stream from the site. Other options include 3-D interactives, virtual labs, and printable activities. 

Biology Junction

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.

Biology Corner

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.

Virtual Urchin

Sounds odd I know, but this robust site hosted by Stanford University utilizes sea urchins as an engaging entry point to life science concepts ranging from basic biology (introductory microscopy and predator-prey relationships) to university-level curriculum (gene function in embryos).


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.

Ward’s Science featuring Ward’s World

Check out Ward’s World, a new destination that offers middle schoolers and their teachers free classroom activities, how-to videos, tips, tricks, and resources that make science easier—and more fun! Find chemistry, biology, physics, and earth science.


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.

Bozeman Science

Want clear, standards-aligned videos? If so, Bozeman Science is a great resource for teaching AP Chemistry. You’ll be able to flip your classroom and provide additional support to your students.

American Association of Chemistry Teachers

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.

Middle School Chemistry

Don’t let the name fool you. Sure, this site is perfect for middle school learners, but if you teach introductory chemistry or physical science, the level of materials is perfect for grades 9-10, as well. Lesson plans are easy to find and some are even available in Spanish for English language learners!


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.

Molecular Workbench

This site facilitates a microscopic understanding of our macroscopic world. You’ll be blown away by resources like their Semiconductor and Chemical Bonding Module. All of the modules contain embedded assessments to keep your students on track and inform you of their progress.

ChemMatters Online

Always free for everyone, this is a terrific resource for middle school and high school science teachers as well as parents. Each issue provides a new collection of articles on chemistry topics that students will find engaging and relatable. The back-issue online library offers interesting downloadable articles on all sorts of chemistry-related topics, while the Teacher’s Guides help you direct your students as they learn from their reading. 


Best Science Websites for Teaching Earth Science

 Annenberg Learner Interactives

The Dynamic Earth Interactive takes students through a visual feast through Earth’s layers and plate tectonics. The lessons can be extended by incorporating the Rock Cycle and Volcanoes Interactives.

National Oceanic and Atmospheric Administration Resource Collections

Along with oceans and coasts, weather and more, instructors can find lesson plans in this collection that contain NOAA data and real-time weather information.

Exploring Earth Investigations

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, including tricky ones like El Niño and Sunspots.


Best Science Websites for Teaching Environmental Science

Global Footprint Network Ecological Footprint Calculator

best science websites high school

If you’re among those who calculates the ecological footprints as an activity in your AP Environmental Science class, you’ll enjoy this site. The questions are relatable to daily life and the quiz can be retaken to analyze how lifestyle changes impact our footprint.

Population Education

This site helps to build a firm foundation so you can fully explore pollution, ecology, and biodiversity. It boasts interactive maps, a Find a Lesson  feature, and learning materials available in Spanish.

The Environmental Literacy Council

For science-based environmental resources, this one is hard to beat. Created by scientists, economists, and educators, the website offers over 1000 pages of curricular materials and textbook reviews on environmental topics.

National Energy Education Development Project

This great resource provides accurate energy usage data and information on energy technological advances through games, kits, math extensions, and their free downloadable Energy Infobooks


Best Science Websites for Teaching Physics

 PhET Interactive Simulations

Complete with teacher-submitted and reviewed lessons, these activities help students explore topics including circuits, waves, and quantum mechanics

The Physics Classroom

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!

Share My Lesson

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!
