##Discover science by doing science

Science is more than formulas, vocabulary, and diagrams. It's a way of making sense of the world—by asking questions, gathering evidence, and testing ideas.

At Khan Academy, we want our learners to experience science in action. That's why we've created hands-on science activities for 5th grade, middle school, and high school. Through these activities, students will explore real-world phenomena, think critically, and build understanding through investigation.

##Explore real-world phenomena

Every activity begins with a phenomenon—something observable and intriguing about the world around us.

Learners will explore questions like:

  • Why does sand at the beach feel hot, even when the water feels cold?
  • How can measuring cellular respiration relate to fitness?
  • How can a skydiver fall safely?

Each activity includes a student guide that walks learners through the investigation step by step. Rather than simply stating the answers to the phenomenon-based questions, the guides prompt students to collect data, analyze patterns, construct explanations, and more.

##Carry out investigations with ease

Khan Academy's hands-on activities can be done wherever learning happens—in a classroom, at home, or anywhere in between. The required materials are easy to find around the house or can be purchased at a low cost, making it simple to jump in and get started.

##Get support from our teacher guides

Our collection includes 5th grade, middle school, and high school activities, covering topics in biology, chemistry, physics, and Earth and space science.

To aid in implementation, we've created comprehensive teacher guides that include:

  • standards alignments,
  • step-by-step instructions,
  • differentiation strategies, and
  • common student misconceptions.

These resources make it easy to facilitate meaningful scientific exploration—whether you're guiding a whole class or supporting learning at home.

##Start investigating, today!

Hands-on science builds more than content knowledge. It helps learners:

  • ask meaningful questions,
  • think critically about evidence,
  • solve problems creatively, and
  • connect science to their everyday lives.

Science isn't just a subject. It's a way of understanding the world.

So—are you ready to do science?
