8 Top Biology Websites for Teachers

The Internet is endless! 

No… really. 

The amount of information on websites for all subjects, biology included, is daunting. No one has time to look through and determine if a website is legitimate or gauge just how well a website will work for them. 

Now, I have done my fair share of vetting and researching the best websites for biology. And I want to share them with you today to save you some time!

Hopefully you will find a new website or two to bookmark for your lessons!

Right, let’s take a look at my top 8 biology websites.

1 – BioEd Online

BioEd Online is a website that provides free resources and professional development opportunities for biology educators. 

The website has a lot of different things to offer, like lesson plans, multimedia resources, and virtual courses. 

The content is aimed at K–12 and higher education and covers a variety of topics, including biotechnology, genetics, and ecology.

BioEd Online is paid for by the Baylor College of Medicine. Its goal is to help teachers get students interested in biology by giving them high-quality resources.

2 – The Biology Corner

Now, The Biology Corner is an amazing resource for biology. I have used it multiple times and always find the information to be accurate and the activities engaging.

The website was created by an experienced high school biology teacher, and it includes a variety of materials such as lesson plans, worksheets, lab activities, quizzes, and other resources organized by topic and grade level.

These materials are meant to help teachers teach biology in a way that is interesting and effective. The content can be used in both high school and college courses.

The Biology Corner also has resources for students, such as interactive quizzes, review sheets, and study guides!

It’s a one-stop-shop!

3 – Understanding Evolution

Understanding Evolution is a website made by the University of California Museum of Paleontology. It has information about evolution and ways to teach and learn about it. 

The website offers a variety of resources, including lesson plans, interactive activities, multimedia materials, and a comprehensive set of frequently asked questions about evolution. Phew!

The materials are organized into several categories, which makes it easier for you to navigate. 

Understanding Evolution is designed to be used by educators in a variety of settings, including K–12 schools, colleges, and universities.

Materials on the website are based on the most recent scientific research. They are made to be useful for both students and teachers.

4 – PhET Interactive Simulations

I use PhET Interactive Simulations almost weekly in my biology classroom.


The best part? All of the virtual simulations are free!

PhET simulations are interactive online games made by the University of Colorado Boulder that let students explore and experiment with a wide range of scientific ideas, including those related to biology. 

The simulations are meant to help students understand scientific concepts better by letting them change variables and see the results of their actions in real time.

The PhET website has many simulations about biology, such as ones about natural selection, photosynthesis, and the copying of DNA. Students can use these simulations as a virtual lab to learn about biological concepts. They have features like customizable settings, interactive models, and real-time feedback.

In my experience, I have used these simulations as supplements to in-class activities or make-up work for students that are absent on lab days. 

There is also a teacher portion of the site that includes various handouts created by other teachers that you can use as guides for the simulations.

5 – NOVA Labs

NOVA Labs Biology is an online resource made by the Public Broadcasting Service for high school students. It has interactive biology labs, designed to promote scientific literacy and engagement in science.

There are a variety of interactive labs, such as the “RNA Lab,” which teaches students about the role of RNA in protein synthesis, and “Evolution Lab,” which allows students to explore the process of natural selection. 

Interactive media, videos, and simulations are used in the labs to keep students engaged.

There are also resources for teachers, such as lesson plans and teacher guides. Woohoo!

NOVA Labs Biology is part of the larger NOVA Labs platform, which has interactive resources in many scientific fields, such as astronomy, physics, and chemistry.

This is awesome if you are teaching multiple subjects!

6 – Annenberg Learner: Rediscovering Biology

Does this name sound familiar?!

Paul Andersen, a high school science teacher from Bozeman, Montana, made Bozeman Science Biology as a way to help students learn biology with easy-to-watch videos.

Paul’s YouTube channel “Bozeman science” is super popular with teachers across the globe.

It is one of my Top 10 YouTube Channels to Use in Your Biology Classes!

The videos on Bozeman Science Biology cover a wide range of biology topics, including cell biology, genetics, evolution, ecology, and more. The videos are designed to be engaging and informative, and they use a variety of graphics and animations to help students understand complex concepts.

Bozeman Science Biology is available online for free and is used by educators and students around the world.

8 – HHMI Biointeractive
