Central to Class CrunchLabs is the creative force of Mark Rober and his globally recognized YouTube team. With over 70 million followers across platforms, the team brings unparalleled expertise in science storytelling and digital engagement. Their content captures attention, sustains curiosity, and makes complex STEM ideas accessible and exciting for students.

The curriculum is built by a team of experienced educators, science writers, and learning specialists, ensuring that every unit is academically rigorous and standards-aligned. By designing for the Next Generation Science Standards (NGSS), the program supports educators in meeting instructional goals while engaging students in deeper learning.

The program builds on CrunchLabs’ proven success with buildable STEM kits and hands-on learning. With a track record of shipping millions of kits, the team’s background in designing STEM learning experiences ensures students don't just watch or read about science in class—they do it.

We believe joy fuels learning.

Students are more willing to grapple with difficult ideas when they are excited, invested, and having fun. Curiosity, surprise, play, and delight are not distractions from rigor; they are what sustain engagement and persistence through challenging thinking. This means learning should feel emotionally engaging and rewarding.

This means we design materials that:

• Use surprising phenomena and visually engaging experiences
• Include exciting videos and playful hands-on moments
• Create opportunities for wonder and discovery

We believe learning is a collaborative endeavor.

Students develop a deeper understanding when they build ideas together, challenge ideas, and make sense of the world as a community. Collaboration is necessary, not optional. Science learning should create opportunities for students to contribute ideas, revise thinking together, and see themselves as part of a collective effort to figure things out.

We design materials that:

• Structure meaningful discussion and shared sensemaking
• Support students to publicly compare, revise, and build on ideas
• Include collaborative investigations and model-building

We believe students should have agency in their learning.

Students grow as self-directed learners when they have agency in the learning process. They need meaningful opportunities to make decisions, pursue questions, shape investigations, and influence how learning unfolds.

This means we design materials that:

• Offer opportunities for choice, ownership, and continuous reflection
• Elevate student questions and investigations
• Allow flexibility in exploration and expression

We believe that students can build creative confidence.

Students learn science when they generate ideas, consider multiple solutions, test possibilities, and improve through iteration. Learning environments should normalize failure, encourage risk-taking, and value growth over perfection. Reflection and revision help students see how their thinking develops over time.

This means we design materials that:

• Encourage multiple approaches, solutions, and perspectives.
• Support student-generated explanations and models in sensemaking
• Foster growth by embracing failure, reflection, and revision.
