Chemistry lab courses have traditionally followed a structured “cookbook” approach, where students perform pre-designed experiments with known outcomes. While this method teaches technical skills, it lacks the excitement and creativity of real scientific discovery. Across STEM disciplines, there is growing momentum to move beyond these standard labs and offer students the chance to engage in active learning that sparks curiosity, builds confidence, and mirrors the work of real scientists.
One way to achieve this is through Course-Based Undergraduate Research Experiences (CUREs). CUREs provide students with opportunities to explore scientific questions. Instead of merely following instructions, students learn to ask their own research questions, design experiments, collect and analyze data, and present their findings—just like professional researchers.
Design and Implementation of the CURE
Our CURE was first piloted in Spring 2023 with Chemistry and Biochemistry majors. After a successful trial run, the program was expanded in Spring 2025 to include every General Chemistry II lab, growing student participation from about 50 to over 300 students!
General Chemistry II was chosen as a key course for this initiative because it serves a wide range of SCSE majors, many of whom are in their first year. Introducing research at this early stage was a bold and exciting challenge. The Wainman research group, who specialize in chemical education research, took the lead in developing a CURE centered on a timely and interdisciplinary topic: biochar.
Biochar-Focused CURE
This unique CURE was developed in collaboration with the Natural Resources Research Institute (NRRI) in Hermantown, MN. NRRI is conducting cutting-edge work on bioengineered carbon materials, particularly biochar, which is gaining attention for its wide range of potential environmental, agricultural, and materials science applications.
Our students investigated how different types of biochar perform as filtering agents for environmental contaminants such as metals and dyes. Working in teams, students developed their own research questions and explored factors such as feedstock type, pore size, and production conditions. Their findings not only contributed to ongoing research at NRRI, but also gave them firsthand experience in conducting meaningful, real-world science.
Looking Ahead
The rollout of the CURE in General Chemistry II labs has been inspiring. The energy, creativity, and curiosity students brought to the project were on full display at the year-end poster session, where they proudly presented their work to peers, faculty, staff, and community stakeholders. For many students, it was their first experience sharing original research, and it sparked a passion for science that will carry forward into future studies and careers.
What makes this CURE especially exciting is that we’re just getting started. Biochar offers a wealth of unanswered questions and untapped possibilities. Whether it’s improving water quality, enhancing soil health, or advancing sustainable technologies, the research potential is enormous. Our students are at the forefront of exploring these challenges, and with continued support from our campus and research partners, this CURE is set to thrive and inspire future generations of scientists!
