Shannon started her journey with Developing Experts by completing PHD placement while studying for her Doctorate in Developmental Biology at the University of East Anglia. Shannon has since joined the team full-time as a Project Manager working with the company's industry partners. Shannon knows a lot about chickens!
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.
Resources:
Method 1: meter ruler with a thin uninsulated wire secured to it with masking tape (copper or constantan); connecting wires; crocodile clips and an ohmmeter.
Method 2: meter ruler with a thin uninsulated wire mounted to it with masking tape (copper or constantan); connecting wires; crocodile clips; 2 cells; voltmeter and an ammeter.
