I am currently a teacher candidate that is training to teach Intermediate/senior level chemistry and biology at the high school level. My love for teaching science comes with a philosophy that students in the 21st century need guiding and counselling to foster critical thinking through inquiry-based learning. My teaching method is scaffolding my lessons and providing learners with big ideas in science so that they can use those resources and tools to solve problems that they are interested in.
