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

PhD Science® is an authentic phenomenon-based K–5 curriculum that provides students with a science education as limitless as science itself. The curriculum’s hands-on approach sparks students’ natural curiosity about the real world and its wonders as they build a deep, lasting knowledge of science concepts that they revisit throughout elementary school.

Science is a dynamic and intriguing field of study. Here's a curriculum that proves it.

What Makes PhD Science Unique?

Students create and observe a chemical reaction in the classroom.

Hands-On Investigations

Don't just memorize science—experience it.

Rather than simply memorizing—and quickly forgetting—definitions, PhD Science students acquire deep and lasting comprehension of scientific concepts through hands-on activities and evidence-based learning.

PhD Science utilizes an Activity Before Concept > Concept Before Terminology approach to give students a point of reference when applying scientific terminology to a concept.

Cross-Curricular Connections

Cross-curricular connections are a key component of the PhD Science learning design, which includes connections to art, literacy, math, social studies, history, geography, and more. This provides students with additional accessible entry points to the topic of study.
