PhD Science students think and act like real scientists as they ask questions, gather evidence, develop models, and construct explanations while investigating authentic phenomena.

All students deserve the opportunity to build an unshakeable knowledge of the scientific world. That’s why we offer PhD Science for Levels K–2 as an open educational resource (OER).

Knowledge Matters Campaign Celebrates PhD Science as A High-Quality Science Curriculum

PhD Science classrooms were visited and celebrated by the Knowledge Matters Campaign with students building enduring knowledge and skills in science, reading, and other areas.

Inspiring students to wonder about the world and empowering them to make sense of it.

Fostering Curiosity to Build Enduring Knowledge

Children are curious and observant and need the opportunity to make sense of the world around them. And yet, when it comes to science instruction, students are too often left reading about scientific discoveries of the past and memorizing scientific facts instead of experiencing science. PhD Science was crafted to change that, leveraging students’ curiosity to build a deep and lasting understanding of science.


PhD Science students acquire deep and lasting comprehension through hands-on activities and evidence-based learning. Students are actively doing science to build knowledge, rather than memorizing and quickly forgetting.

Learn How Materials Kits Support Hands-On Learning.


Teachers facilitate the learning, but students own it. Like real scientists, they ask questions, synthesize information, and apply their understanding to new contexts. 

Get Access to the Curriculum.


Each lesson builds on the lessons before it, so students develop their understanding of science concepts in the context of each module's anchor phenomenon.

Through this knowledge-building approach, PhD Science students develop problem-solving and critical-thinking skills that extend well beyond a science lesson.

PhD Science Level 3 Module 1 Science Logbook

Building Science Knowledge Through Fine Art

Art and science both begin with a sense of wonder that invites students to observe, question, and make sense of the world around them. Artists often highlight specific aspects of a phenomenon, sparking students’ curiosity about it and providing them with a new access point into the learning. See how PhD Science weaves art into science content, allowing students to practice the scientific skills of making observations, asking questions, and noticing patterns while they share what they notice and wonder.

Everything Needed to Teach and Do Science

PhD Science includes print, digital, and hands-on materials kits designed to spark student curiosity and provide
teachers with high-quality instructional materials to lead every science lesson with confidence.
