Khan Academy science is your free, one-stop-shop for high-quality, standards-aligned content. Whether you’re introducing students to cells for the first time, exploring the ins and outs of chemical reactions, or guiding learners through the complexities of kinematics, you’ll find the right tools to bring science to life in your classroom.

Here’s what makes our science resources stand out:

Courses offered

Khan Academy offers engaging, comprehensive science courses for middle school, high school, and Advanced Placement (AP) levels. They are designed to engage students with high-quality, rigorous content. All courses are aligned to the Next Generation Science Standards (NGSS) or the College Board Course and Exam Descriptions (CEDs) and incorporate real-world phenomena and science practices.

Middle school courses introduce core topics in Earth science, life science, and physical science with curiosity and clarity. 

High school courses build deep understanding through rigorous, interactive content and real-world contexts.

AP courses mirror the scope and sequence of the College Board curriculum and help students prepare for exam success.

Each course includes videos, articles, and practice questions that help students master key concepts and skills.

Interactive, hands-on learning

Science is best learned through doing. So at Khan Academy, we go beyond videos and quizzes.

• Hands-on activities prompt students to explore and investigate science in action with real-world questions and simple materials. Our growing collection of middle and high school activities help students connect what they learn in class to the world around them.

• Simulations in articles and exercises let students manipulate variables, observe outcomes, and build understanding in interactive ways. Each simulation is rooted in a real-world phenomenon, designed to be relevant and engaging for learners.
  • Simulations are included in:

With these hands-on, interactive resources, students don’t just memorize facts—they analyze data, construct explanations, engage in scientific reasoning, and more.

*Simulation-based articles can be found in our middle school physics course. Check out an example here.

Teacher tools for easy planning

We know how busy science teachers are. That’s why we’ve created unit guides and planning tools to help you bring Khan Academy into your classroom with ease.Our goal is to help teachers save time while delivering meaningful, standards-based instruction. Every High School unit guide includes:

• Lesson overviews and essential questions
• Learning objectives and teaching tips
• Ideas for integrating Khan Academy videos, articles, and exercises
• Relevant phenomena to anchor lessons
• Common misconceptions and how to address them
• Student resources, such as simulations, note taking templates, and more!

Whether you’re planning a full unit or just looking for a supplemental resource, Khan Academy makes it easy to find what you need, when you need it.

Texas teachers, we’ve got you covered

Khan Academy offers a robust set of science resources designed specifically to support Texas teachers and students. Our TEKS-aligned science courses ensure comprehensive coverage of required content. 

Each unit in these courses is accompanied by high-quality, teacher-facing unit guides. These guides include learning objectives, teaching tips, common student misconceptions, and Texas-specific phenomena to anchor instruction.

Whether you’re planning a full curriculum or supplementing classroom instruction, these resources are built to help Texas educators teach with confidence and flexibility.
