Kate Richards

Kate’s journey as a science educator spans over 15 enriching years. Her passion for unravelling the complexities of the human body led her away from medicine (as she hates blood but loves medical t-shows) and into the world of teaching. She’s had the privilege of nurturing young minds in KS3 and KS4 science, guiding A-level Biology students, and even taught year 4 students in Spain, broadening her teaching horizons early in her career. Kate holds a Masters in Teaching (MTeach) and specialises in biology. Her research for her Master's degree focused on the profound impact of self-efficacy on classroom learning. Beyond the classroom, she finds solace in leisurely family walks and exploring new destinations through travel. She finds that the most rewarding aspect of teaching is witnessing those magical "light bulb moments" when students grasp the intricacies of science right before her eyes.
